Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It will be appreciated that the method may be applied to a terminal, a server, a system comprising a terminal and a server, and implemented by interaction of the terminal and the server.
In some embodiments, as shown in fig. 1, a method for transferring a transaction by using a resource is provided, where the method is applied to a terminal for illustrating, it is understood that the method may also be applied to a server, and may also be applied to a system including the terminal and the server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
Step S102, a main transaction for a target resource transfer task is acquired.
Wherein the main transaction comprises at least one sub-transaction.
The sub-transactions are data table adjustment transactions for the target resource transfer task.
In practical application, a main transaction can comprise a plurality of sub-transactions, and when the plurality of sub-transactions comprising the main transaction are all completed, the main transaction is completed; taking a main transaction as an example of book selling, a first sub-transaction is used for reducing inventory, a second sub-transaction is used for obtaining income, the first sub-transaction and the second sub-transaction jointly form the main transaction, and the first sub-transaction and the second sub-transaction are completed, namely, the book selling flow corresponding to the main transaction is completed.
As one example, in response to a transaction instruction for a target resource transfer task, a server determines a master transaction corresponding to the target resource transfer task, and the server determines a number of sub-transactions included in the master transaction.
Step S104, for any sub-transaction in each sub-transaction, transaction data to be adjusted corresponding to any sub-transaction is obtained from the database.
The database may refer to a database where a data table that needs to be processed by each sub-transaction is located.
The transaction data to be adjusted may refer to data to be adjusted in a data table to be adjusted in a sub-transaction when the processing state of the sub-transaction is set to a completion state, and in practical application, when the transaction data to be adjusted in the data table to be adjusted in a certain sub-transaction is adjusted, the processing state of the sub-transaction may be set to the completion state.
As an example, since the main transaction includes several sub-transactions, for any of all the sub-transactions included in the main transaction, the server determines the data table in which each sub-transaction needs to be adjusted using sql parsing, and the server determines the transaction data to be adjusted in the data table.
Step S106, under the condition that the data adjustment authority for the transaction data to be adjusted is obtained, the data table adjustment operation matched with the target resource transfer task is executed for the transaction data to be adjusted, and the adjusted transaction data corresponding to any sub-transaction is obtained.
The data adjustment authority may refer to an authority that an initiator of the data adjustment operation should have when performing data adjustment on transaction data to be adjusted corresponding to each sub-transaction, in practical application, the transaction with the data adjustment authority may perform data adjustment on the transaction data to be adjusted, the data adjustment authority may include an instruction implemented by a database statement, and the data adjustment authority may include a local lock.
As an example, a server obtains a local lock for transaction data to be adjusted, the server performs a data table adjustment operation matched with a target resource transfer task on the transaction data to be adjusted corresponding to each sub-transaction, the server obtains adjusted transaction data corresponding to any sub-transaction, the server generates a rollback log for the data table adjustment operation, and each sub-transaction corresponds to one rollback log.
Step S108, under the condition that the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, the processing state of the main transaction is updated.
As an example, the server obtains the global lock, the server sends the adjusted transaction data corresponding to each sub-transaction to the database, when the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, the server deletes the rollback log corresponding to each sub-transaction, the server sets the processing state of each sub-transaction to be a successful state, and the server updates the processing state of the main transaction to be a successful state.
According to the resource transfer transaction processing method, the sub-transaction included in the main transaction is determined by acquiring the main transaction aiming at the target resource transfer task, namely, the data table adjustment transaction aiming at the target resource transfer task and included in the main transaction is determined, for any sub-transaction in all sub-transactions, the to-be-adjusted transaction data corresponding to any sub-transaction is acquired from the database, so that the data to be adjusted of each sub-transaction is positioned, under the condition that the data adjustment authority aiming at the to-be-adjusted transaction data is acquired, the data table adjustment operation matched with the target resource transfer task is performed on the to-be-adjusted transaction data, so that the adjusted transaction data corresponding to any sub-transaction is obtained, the transaction with the related data adjustment authority is adjusted on the basis of the data adjustment authority, the data is prevented from being confused due to the fact that a plurality of transactions are adjusted simultaneously, under the condition that the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, the processing state of the main transaction is updated on the basis of a plurality of sub-transactions, the processing state of the sub-transaction is updated on the basis of the fact that the data corresponding to the sub-transaction is successfully submitted, and the state of each sub-transaction is updated is prevented from being updated, and accordingly, the transaction efficiency after the transaction state adjustment is improved is achieved.
In some embodiments, as shown in fig. 2, in a case where the data adjustment authority for the transaction data to be adjusted is acquired, performing a data table adjustment operation matching the target resource transfer task on the transaction data to be adjusted, including:
step S202, obtaining a local data adjustment permission code for transaction data to be adjusted.
The local data adjustment permission code may refer to a local lock, in practical application, the local lock may be implemented by a statement of a database select.
As one example, as each sub-transaction is processed by a server, the server obtains a local lock for the transaction data to be adjusted and the server runs the local lock.
Step S204, responding to the local data adjustment instruction corresponding to the local data adjustment authority code, and executing the data table adjustment operation matched with the target resource transfer task on the transaction data to be adjusted.
As an example, after the server acquires the local lock, the server responds to a local data adjustment instruction corresponding to the local lock and aiming at the transaction data to be adjusted, the server executes data table adjustment operation matched with the target resource transfer task on the transaction data to be adjusted, and the server obtains modified transaction data corresponding to the transaction data to be adjusted.
In step S206, when the data table adjustment operation is completed, the execution of the local data adjustment authority code is canceled.
As an example, after the server performs a data table adjustment operation matching the target resource transfer task on the transaction data to be adjusted, the server cancels the execution of the local lock, i.e., the server releases the local lock.
In this embodiment, by acquiring the local data adjustment permission code for the transaction data to be adjusted, and responding to the local data adjustment instruction corresponding to the local data adjustment permission code, performing a data table adjustment operation matched with the target resource transfer task on the transaction data to be adjusted, and under the condition that the data table adjustment operation is completed, canceling the execution of the local data adjustment permission code, the data confusion caused by the concurrent modification of data of a plurality of transactions can be prevented based on the local lock, and the transaction data processing accuracy is ensured.
In some embodiments, the above method further comprises: acquiring global data submission authority codes of the adjusted transaction data corresponding to each sub-transaction; and responding to a data submitting instruction corresponding to the global data submitting authority code, and submitting the adjusted transaction data corresponding to each sub-transaction to a database.
The GLOBAL data submitting authority code may refer to a GLOBAL LOCK, in practical application, the GLOBAL LOCK is implemented by a code, and maintains information through a database table global_lock_info, and indicates that data with an id of Y in an X-sheet table is in distributed transaction, and modification is not allowed; internal transactions can be prevented from accessing each other, the global lock prohibits inter-transaction modification data from the code layer, and only the global lock is taken, the server can submit local transactions.
As an example, after the server performs the data table adjustment operation matched with the target resource transfer task on the transaction data to be adjusted, the server obtains adjusted transaction data corresponding to any sub-transaction, after the server acquires the global lock, the server responds to a data submission instruction corresponding to the global data submission authority code, and the server submits the adjusted transaction data corresponding to each sub-transaction to the database.
In this embodiment, the global data submission authority code of the adjusted transaction data corresponding to each sub-transaction is obtained; and responding to a data submitting instruction corresponding to the global data submitting authority code, and submitting the adjusted transaction data corresponding to each sub-transaction to a database, so that the modified transaction data can be accurately submitted based on the global lock, and the transaction processing accuracy is improved.
In some embodiments, the above method further comprises: generating a data recovery log corresponding to each sub-transaction according to the transaction data to be adjusted and the adjusted transaction data corresponding to each sub-transaction; and under the condition that the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, deleting the data recovery log, and updating the processing state of the main transaction to a completion state.
The data recovery log may refer to data used for recording data adjustment operations of the transaction data to be adjusted corresponding to each sub-transaction, and in practical application, the data recovery log may include a rollback log.
As an example, in the process of performing data adjustment operation on the transaction data to be adjusted corresponding to each sub-transaction, the server generates a rollback log corresponding to each sub-transaction according to the transaction data to be adjusted and the adjusted transaction data, in practical application, the server records the transaction data to be adjusted corresponding to each sub-transaction in the rollback log, that is, the server records the transaction data before adjustment of each sub-transaction in the rollback log, the server can restore the transaction data to a state before data start according to the rollback log, when the server successfully submits the modified transaction data corresponding to each sub-transaction to the database, the server determines that the processing state of each sub-transaction is a successful state, the server deletes the rollback log, and the server updates the processing state of the main transaction to a completion state.
In this embodiment, a data recovery log corresponding to each sub-transaction is generated according to the transaction data to be adjusted and the adjusted transaction data corresponding to each sub-transaction; under the condition that the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, deleting the data recovery log, updating the processing state of the main transaction to be the completion state, determining the rollback log based on the transaction data to be adjusted and the adjusted transaction data corresponding to each sub-transaction, ensuring the sustainable operation and the data stability of the transaction processing by using the rollback log, and under the condition that the adjusted transaction data corresponding to each sub-transaction is successfully submitted to the database, deleting the data recovery log, updating the processing state of the main transaction to be the completion state, and improving the transaction processing accuracy.
In some embodiments, the above method further comprises: under the condition that the transaction data corresponding to at least one sub-transaction in each sub-transaction fails to be submitted to the database, according to the data recovery log corresponding to each sub-transaction, the transaction data corresponding to each sub-transaction after adjustment is recovered to the transaction data corresponding to each sub-transaction to be adjusted; and deleting the data recovery log corresponding to each sub-transaction.
As an example, when the server detects that the transaction data corresponding to at least one sub-transaction in each sub-transaction fails to be submitted to the database, the server restores the adjusted transaction data corresponding to each sub-transaction to the transaction data to be adjusted corresponding to each sub-transaction according to the data restoration log corresponding to each sub-transaction, the server deletes the data restoration log corresponding to each sub-transaction, the server acquires the local lock of the transaction data to be adjusted corresponding to each sub-transaction again, the server executes step S106 and subsequent steps until the server successfully submits the modified transaction data corresponding to each sub-transaction to the database, the server determines that the processing state of each sub-transaction is a successful state, the server deletes the rollback log, and the server updates the processing state of the main transaction to a completion state.
In this embodiment, under the condition that the transaction data corresponding to at least one sub-transaction in each sub-transaction fails to be submitted to the database, according to the data recovery log corresponding to each sub-transaction, the adjusted transaction data corresponding to each sub-transaction is recovered to the transaction data to be adjusted corresponding to each sub-transaction; deleting the data recovery log corresponding to each sub-transaction can recover the transaction data according to the rollback log based on the rollback log under the condition that the transaction data is failed to be submitted after adjustment corresponding to the sub-transaction, thereby ensuring the consistency of the transaction data and improving the transaction processing accuracy.
In some embodiments, obtaining transaction data to be adjusted corresponding to any sub-transaction from the database includes: acquiring a data table to be adjusted corresponding to any sub-transaction from a database; determining the position of data to be adjusted in a data table to be adjusted; and determining transaction data to be adjusted according to the position of the data to be adjusted.
The data table to be adjusted may refer to a data table where transaction data to be adjusted corresponding to the sub-transaction is located.
The data position to be adjusted may refer to position information of the transaction data to be adjusted corresponding to the sub-transaction in the data table to be adjusted, and in practical application, the data position to be adjusted may include a data line position and a data id.
As an example, a server acquires a data table to be adjusted corresponding to any sub-transaction from a database, the server determines position information of the transaction data to be adjusted in the data table to be adjusted according to data types of the transaction data to be adjusted corresponding to each sub-transaction, the server determines the transaction data to be adjusted according to positions of the data to be adjusted, and the server records the transaction data to be adjusted in rollback logs corresponding to each sub-transaction.
In this embodiment, the obtaining transaction data to be adjusted corresponding to any sub-transaction from the database includes: acquiring a data table to be adjusted corresponding to any sub-transaction from a database; determining the position of data to be adjusted in a data table to be adjusted; according to the position of the data to be adjusted, the transaction data to be adjusted is determined, the transaction data to be adjusted corresponding to each sub-transaction can be determined based on the position of the data to be adjusted in the data table to be adjusted corresponding to each sub-transaction, the transaction data to be adjusted is accurately positioned, and the transaction processing accuracy is improved.
In some embodiments, obtaining a master transaction for a target resource transfer task includes: acquiring a field identification of a target resource transfer task; and determining the main transaction corresponding to the target resource transfer task according to the field identification.
The field identifier may refer to an identifier that characterizes a transaction type corresponding to the target resource transfer task, and in practical application, the field identifier may include @ TccAction annotation.
As an example, when the target resource transfer task is started, the server scans the service stub of the transaction related to the target resource transfer task, and when the server detects that the service stub contains the field identifier corresponding to the target resource transfer task, the server determines the transaction containing the field identifier corresponding to the target resource transfer task in the service stub as a sub-transaction, where the sub-transactions together form a main transaction, that is, the server determines the main transaction corresponding to the target resource transfer task.
In this embodiment, the field identifier of the target resource transfer task is obtained; according to the field identification, the main transaction corresponding to the target resource transfer task is determined, the transaction object corresponding to the target resource transfer task can be accurately determined based on the field identification, and the transaction accuracy is improved.
For the understanding of those skilled in the art, fig. 3 exemplarily proposes a flow chart of a resource transfer transaction processing method, taking a main transaction as an example of selling books, where the main transaction includes two sub-transactions, a first sub-transaction is to reduce inventory, a second sub-transaction is to obtain income, the first sub-transaction and the second sub-transaction together form a main transaction to complete the book selling flow, a method defining the main transaction is named selbook, a method of the first sub-transaction is named as decreestore, a method of the second sub-transaction is named as addAccount, the decreestore needs to operate the store data table to let the value of the transaction data a to be adjusted be-1, the addAccount needs to operate the account data table to let the value of the transaction data B to be adjusted be +10, and a clean sub-transaction of another main transaction needs to modify the store data table to let the corresponding value of the transaction data a to be-100, where the processing logic of a resource transfer task can be expressed as: the server analyzes the service sql to obtain a table name, id and the like needing to be modified, the descalestore obtains a local lock, the descalestore obtains a global lock, the server executes the service sql, the server modifies the service data (not submitted) to obtain modified service data, the server generates a rollback log (not submitted), the descalestore releases the global lock (not submitted), the server simultaneously submits the modified service data, the rollback log and the released global lock of the sub-transaction descalestore in one local transaction (the local transaction is the function of the database, the database can ensure that all the local transactions are submitted) to the database, if the server needs to execute a cleanup sub-transaction, the server tries to modify the storage table, the modification fails because the local lock cannot be obtained, the descalestore releases the local lock, releases a connection resource, the server executes the cleanup sub-transaction, the server modifies the cleanup sub-transaction, and the cleanup sub-transaction corresponds to the database which is not successfully modified, but the database is only able to modify the database A, and the database is not successfully modified; the method comprises the steps that a server performs try logic, the server analyzes service sql to obtain table names, ids and the like to be modified, the addAccount obtains local locks, the addAccount obtains global locks, the server performs execution service sql, the server modifies service data (not submitted), the server generates a rollback log (not submitted), the addAccount releases the global locks (not submitted), the server simultaneously submits the modified service data of the addAccount, the rollback log and the released global locks in a local transaction (the local transaction is the function of a database, the database can ensure to be submitted), the addAccount releases the local locks, releases connection resources, and releases global locks, if a clean sub-transaction tries to obtain the global locks, the server can obtain success and successfully submit, and at the moment, the value of the transaction data A to be regulated in a store data table in the database is-101, the addaccoundstock releases the global locks, the addaccoundstock executes a concim logic, and the addaccoundstock performs self logic; the try logic and the confrim logic may include a try phase and a confrim phase of the TCC mode, among others.
In an exemplary embodiment, the existing TCC mode has the disadvantage of strong service intrusion, three phases of the TCC mode all need to be accessed to apply self-design and coding, the TCC mode is adapted to the AT mode, the AT mode can ensure the advantage of strong isolation and supplement the disadvantage of the TCC mode, the three phases of operation generated automatically are utilized to reduce the service intrusion, and if the AT sub-transaction is adapted to the TCC mode, the situation to be completed can be expressed as: (1) Try: and analyzing the service sql, submitting the service data, the rollback log and the global lock in the same local transaction, and releasing the local lock and the connection resource, wherein the connection resource refers to the resource of the connection database. The database connection itself consumes resources such as network, memory, CPU and the like, so the database connection needs to be released in time after the use is finished; (2) Confirm: deleting the rollback log; (3) cancer: and rolling back by using the rollback log, and then deleting the rollback log. Table structure changes that need to be made for AT mode adaptation TCC mode may include: (1) dtx_tcc_sub: the original sub-transaction table needs to have a field added to indicate whether this is a sub-transaction for an AT; (2) GLOBAL_LOCK_INFO: the sub-transaction newly-added table is used for recording the information of the global lock, and main fields include a main transaction id, a sub-transaction id, a line number, a database name, a table name and the like. The local lock representation may modify local data, while the global lock representation may commit. The transaction needs to check whether this in-table lock is released before commit, where the global lock is released when the try phase is performed, whether successful or failed; (3) UNDO_LOG: the sub-transaction newly-added table is used for recording the rollback log of the sub-transaction, and the SQL analysis can be utilized to obtain the data change related to a certain transaction processing service, namely, the main transaction id, the sub-transaction id, the table name, the line number, the value before change, the value after change and the like.
In one exemplary embodiment, the sub-transaction of the At mode does not require the write try, confirm, cancel method, only the write traffic method, but the At requires an automatic three phase registration method due to the need to adapt the TCC mode and the great similarity in flow of the At mode. In practical application, a field is first added to the @ TccAction note to identify whether this is an AT sub-transaction, useAt defaults false. Similar to the Spring-based loading of beans for TCC traffic handling in the traditional TCC mode, such as abstract reference Proxyfactor, these beans scan the service stubs associated with TCC AT application start, the service stubs scan AT application start, if this annotation is scanned and useat=true is obtained, it is known that this is an AT sub-transaction, this annotation needs to be stored in context, with continuous delivery of service calls. In the case of TCC sub-transactions, we need to record service names, try methods, confirm methods, and cancel methods, etc. in the cache, however, one AT sub-transaction, like recording service names, its try methods record service codes, confirm and cancel records really about to be executed are confirm methods and cancel methods provided by attunextractor, and one service can be written, named attunextractor, in which fixed confirm methods and cancel methods are written. Because of the special design of the AT mode, all sub-transaction confirm methods delete the corresponding images, all cancel methods restore data using images and then delete images, each sub-transaction is executed only for the corresponding images, and images are distinguished by sub-transaction ids, which are recorded in the transaction context. The application does not need to rewrite any TCC code, and only needs to write business logic in the method of @ TccAction mark.
In an exemplary embodiment, the AT identification needs to be transferred by using a Filter of an RPC framework, such as a Filter mechanism of Dubbo, writing dubbotccconsummer Filter, setting useat=true in an indication when a service is invoked, and the DubboTccProviderFilter obtains the identification from the indication and then sets the identification in TccTransactionContext to be transferred along with a thread; the AT mode needs to walk the database agent, the database agent is enhanced in front and behind the conventional database operation, when the framework calls AT mode sub-transaction, processing logic needed by the framework is added when the written service code is applied, then the connection agent is returned, and then the SQLStatent agent is returned, the SQLStatent agent generates a rollback log by utilizing SQL analysis, wherein the SQL analysis can be realized by means of related tools, such as a drive, the SQLStatent object is taken by the agent, then the MYSQLSchemastatVisor is used for establishing a server, then the table-name can be obtained by the object table, the table value can be obtained by the operation (such as SELECT), the value of where the window condition value, the value of the insert and the like can be obtained by traversing, if the SQL statement is only the SELECT statement, the rollback log can be not needed, the condition in the SQL can be obtained, the modified data can be found, and the data before the data can be updated can be recorded; the front mirror image of insert only needs to show that the new data is deleted when rolling back, and the front mirror image of delete only needs to record the deleted data, and the data is reinserted when rolling back.
In this embodiment, an AT sub-transaction is introduced into a TCC mode, the AT sub-transaction is adapted to the TCC mode, and three phases of the AT sub-transaction are automatically registered, so that the AT mode joins in the TCC mode, the AT sub-transaction identifier is transmitted by using a Filter mechanism, and the AT sub-transaction is completed by using SQL parsing and a database proxy, so that the AT mode and the TCC mode can be adapted to realize a resource transfer transaction, thereby reducing the business invasiveness of the TCC mode to the original processing framework, simplifying the processing flow of the resource transfer transaction, and improving the transaction processing efficiency.
