Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The transaction rollback method provided by the embodiment of the invention can be applied to the environment shown in fig. 1. Referring to fig. 1, the server 102 receives a transaction rollback instruction sent by the terminal 104. Specifically, the server 102 communicates with the terminal 104 through a network, the server 102 receives a transaction rollback instruction sent by the terminal 104, and the transaction rollback instruction carries a rollback mode; if the rollback mode is partial rollback carrying the screening condition and the transaction batch identifier, screening out target transactions meeting the screening condition from the transactions corresponding to the transaction batch identifier; detecting a transaction state of a target transaction; and if the transaction state of the target transaction is processed, rolling back the target transaction. The terminal includes, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. It should be noted that the transaction rollback method provided by the embodiment of the present invention may also be implemented only through the server 102.
In one embodiment, as shown in fig. 2, there is further provided a server, where the server includes a processor, a non-volatile storage medium, an internal memory, and a network connection port, which are connected by a system bus, and the non-volatile storage medium stores therein an operating system and computer-executable instructions for implementing the medical service reservation method provided in this embodiment. The processor is used for improving the calculation and control capacity and supporting the operation of the whole server. The internal memory is used to provide an environment for the operating system and the execution of computer-executable instructions in the non-volatile storage medium. The network interface is used for network communication with the terminal. Those skilled in the art will appreciate that the architecture shown in fig. 2 is a block diagram of only a portion of the architecture associated with the subject application, and does not constitute a limitation on the servers to which the subject application applies, and in particular that a server may include more or fewer components than shown, or combine certain components, or have a different arrangement of components.
In one embodiment, as shown in fig. 3, there is provided a transaction rollback method, which is described as applied to a server as in fig. 2, including:
The transaction rollback means that after a client directly or indirectly performs product trading on the internet (for example, fund transaction), data obtained after the transaction is executed becomes meaningless due to changes of transaction parameters and the like (for example, when the net value of a unit of the fund buying transaction on the same day changes, the share of the fund purchased by the user changes, and the share of the fund obtained by originally executing the fund transaction is no longer useful), so that the data obtained after the transaction is required to be restored to the last correct state.
The transaction rollback instruction may be an instruction for presetting timing start, or an instruction initiated by an operator in real time through a terminal. In an embodiment, the server starts a preset transaction rollback instruction according to a preset start time, for example, the transaction rollback instruction is started at 5 pm and 6 pm of 25 th in 2017, the transaction rollback instruction carries data indicating a rollback mode, and if the transaction rollback instruction carries a screening condition and a transaction batch identifier, the rollback mode is partial rollback in the transaction corresponding to the transaction batch identifier, and if the transaction rollback instruction only carries the transaction batch identifier, the rollback mode is full rollback of the transaction corresponding to the transaction batch identifier. In other embodiments, the terminal operator first enters data indicating the rollback mode, and specifically, may select a dimension of the filter condition in a given filter condition drop-down list, and then enter a specific filter form corresponding to the dimension of the filter condition in a text box, such as the selected dimension of the filter condition being a transaction product, entering a transaction product name or a transaction product identifier in the text box, and/or entering (or selecting) a batch identifier in which the transaction to be rolled back is located in a given batch identifier input box (or selection box), and then sending a transaction rollback instruction to the server by clicking a "send" button.
The rollback mode includes full rollback and partial rollback. The full rollback refers to rolling back the received batch transaction data, wherein the batch transaction data may be transaction data with a transaction application date as a batch identifier. Specifically, the transaction application date may be a specific date (e.g., 7/month 2 of 2017) or a time range (e.g., 6/month 2 of 2017 to 7/month 2 of 2017).
And 304, if the rollback mode is partial rollback which carries the screening condition and the transaction batch identifier, screening out target transactions which meet the screening condition from the transactions corresponding to the transaction batch identifier.
The screening conditions are based on actual transaction requirements. In this embodiment, the filtering condition includes at least one of two dimensions of a transaction product and a transaction user. Specifically, the expression form of the trading product may be a trading product name, a trading product type, or a trading product identifier (such as a product code); the expression form of the transaction user can be a transaction product holding user name, or a transaction product holding user identifier (such as a user identification number) and the like. It should be noted that the screening conditions are not limited to the screening conditions of two dimensions of the transaction product and the transaction user listed in this embodiment, and in this embodiment, screening conditions of other dimensions may also be formulated according to actual transaction requirements.
The transaction lot identifier is used to uniquely identify the received batch transaction, and specifically may be a transaction application date, such as the lot 20170405, or a variant of a string based on the transaction application date, such as the lots 20170405001 and 20170405002, or a transaction lot identifier generated by a custom rule, such as the lot S342209A. In addition, the number of received transaction batch identifiers is not limited, and may be one or more.
The target transactions are screened out from the transactions stored in the server based on the screening criteria and the transaction batch identification. The transactions stored by the server are obtained from a sales platform such as a bank. For example, if the screening condition is a fund product identification of 004282 and the transaction lot identification of 20160504, then the target transaction is a fund transaction in which the user purchased or redeemed the fund product identification of 004282 in a fund transaction conducted on the day of 2016, 5, 4; or the screening condition is that the fund transaction holds the user identifier of 342401196802058475, the transaction batch identifiers are 20160504, 20160505 and 20160506, and the target transaction is the fund transaction which is carried out by the user with the user identifier of 342401196802058475 in 2016, 5-month-4-2016 to 5-month-2016, 6-three days.
At step 306, the transaction status of the target transaction is detected.
For transaction products with large transaction amount, transaction data are processed by adopting a multi-thread parallel execution mode, so that after target transactions are screened out, the transaction state of the target transactions also needs to be detected. The transaction state comprises three states of pending, processing and processed. Specifically, after the server receives transaction data carrying a transaction batch identifier uploaded by a terminal, the transaction data is stored in a database and marked as a to-be-processed state; the server detects whether the transaction in the pending state is in the database or not at regular time, if so, the processing state of the transaction is changed into the processing state, and the transaction is executed according to a preset transaction execution rule; when the transaction is successfully executed, such as in a fund purchase transaction, the server successfully writes the fund share of the fund transaction into the database and sends the fund share to the user terminal, and the processing state of the transaction is changed into the processed state.
In this embodiment, after the target transaction meeting the screening condition is found out from the received batch transactions, the transaction state of the target transaction needs to be detected, and corresponding subsequent operations are performed according to the transaction state.
In this embodiment, if the transaction state of the target transaction is processed, it indicates that the target transaction is in the executing batch transaction, and the target transaction is processed, the target transaction can be rolled back, and there is no influence on the non-target transaction in the batch transaction still in the executing state; or the batch transaction of the batch of the target exchange is processed, the target transaction can be rolled back. In addition, after the target transaction rollback is successful, the target transaction needs to be re-executed according to the changed value of the transaction execution parameter, so that the server sends data obtained after the target transaction is re-executed to the terminal. For example, a client spends 2000 yuan in 7/3/2017 to purchase a fund, the server acquires that the unit net worth of the fund is 1 yuan/share in 7/3/2017, informs the client that 2000 shares of the fund are purchased, and the unit net worth of the fund is 1.5 yuan/share in 8/3/2017, so that the server is required to perform transaction rollback, change the account assets of the client in 8/3/2017 into the total account assets in 6/3/2017, namely empty, and re-read the unit net worth data of the fund in 8/3/2017, thereby calculating that the client owns 3000 yuan.
In this embodiment, after the batch transaction is being executed or is completed, it is found that parameters of part of the received batch transaction are changed, and only the part of the transaction needs to be rolled back.
In one embodiment, as shown in FIG. 4, the step of rolling back the target transaction includes:
The execution flow of the transaction is preset, and the data written into the database in the execution process of the transaction is determined. For example, the execution flow of each fund transaction is as follows: reading the fund transaction type, if the fund transaction type is purchase, reading the fund transaction amount, obtaining the unit net value of the fund transaction application date provided by the fund net value interface, calculating the user holding share according to the fund transaction amount and the unit net value, calculating the current user holding share according to the calculated user holding share and the pre-stored user historical holding share, obtaining the current unit net value of the fund, and calculating the current asset net value according to the current user holding share and the current unit net value; if the fund transaction type is redeemed, the share held by the user is read, the unit net value of the fund transaction application date provided by the fund net value interface is obtained, the redeemed amount of the user is calculated according to the share held by the user and the unit net value, the current unit net value of the fund is obtained, and the current equity is calculated according to the current unit net value of the fund and the pre-stored historical share held by the user. Thus, the data written to the database during execution of the fund transaction is the user's share or the user's redemption amount. Then, for rollback of the target transaction, the value corresponding to the user's share (fund transaction type is purchase) or the value corresponding to the user's redeemed amount (fund transaction type is redemption) written into the database during the execution of the target transaction needs to be modified to be null before the execution of the transaction, and the current net asset value is changed to be the historical net asset value before the execution of the transaction.
After the target transaction is executed, the transaction state is changed to a "processed" state. Then, for rollback of the target transaction, the transaction state needs to be modified to a "pending" state.
In the embodiment, the rollback of the target transaction is realized through the program codes, instead of the rollback of the target transaction through the database, when the rollback of the target transaction has a problem, the error position can be positioned in real time, so that the problem is solved in time, the data rollback is carried out again, and the timeliness of transaction processing is ensured.
In one embodiment, as shown in fig. 5, after step 308, the method further includes:
step 502, if the rollback mode is partial rollback with transaction data, analyzing the transaction data to obtain a transaction product identifier, a transaction application date and a transaction product holding user identifier.
In this embodiment, the transaction data is generated by a user directly or indirectly performing a trade transaction operation via the internet. For example, the fund transaction data includes: the fund holds user identification, fund transaction type, fund identification, fund transaction application date, transaction amount or user hold share, etc.
And step 504, if the transaction product identification is consistent with the preset additional transaction product identification in comparison and the transaction application date is earlier than the current date, searching for the transaction to be rolled back which is stored in the database, identical to the transaction product identification and the transaction product holding user identification and has the transaction application date later than the transaction application date.
In this embodiment, if the transaction product identifier is consistent with the preset additional transaction product identifier, it is indicated that the transaction product is a transaction product capable of performing additional transaction data operation, and the transaction application date is earlier than the current date of the system, which indicates that additional transaction data of the transaction product is currently required to be performed. Then, after the transaction data of the transaction product is additionally recorded in the system, all transaction data after the additional transaction application date need to be rolled back before executing the additional transaction data.
For example, for some low volume fund products, the system does not perform batch transactions every day, but rather performs post-transaction subsidies. Taking the transaction application date as the transaction batch identifier as an example, the following description is made: when the transaction with the transaction batch identifier 20170605 is entered first and the transaction with the transaction batch identifier 20170302 is entered later, transaction data rollback is performed before the transaction with the transaction batch identifier 20170302 is executed, that is, the transaction data with the transaction batch identifier 20170605 is restored to the state with the transaction batch identifier 20170301.
At step 506, the transaction to be rolled back is rolled back.
In the embodiment, a single-thread execution mode is adopted for processing the transaction data with a smaller transaction amount, so that before the additional transaction is executed, the transaction data to be rolled back needs to be directly rolled back after the transaction to be rolled back is determined, namely, a data value written into a database in the execution process of the transaction to be rolled back is changed into a data value before the transaction to be rolled back is executed, and the transaction state of the transaction to be rolled back is modified into a state to be processed.
In the embodiment, the rollback method for partial rollback of the transaction product with large transaction amount is provided, and the rollback method for partial rollback of the transaction product with small transaction amount due to the additional transaction is also provided, so that the system can perform rollback in different modes according to the transaction amount of the transaction product, and the flexibility of transaction rollback is improved.
In one embodiment, as shown in fig. 6, after step 308, the method further includes:
Similarly, the transaction batch identifier is used to uniquely identify the received batch transaction, and specifically may be a transaction application date, or a variant of a character string based on the transaction application date, or a transaction batch identifier generated by a custom rule, or the like. In addition, the number of received transaction batch identifiers is not limited, and may be one or more.
At step 604, the transaction status of the transaction corresponding to the transaction batch identifier is detected.
Similarly, for a transaction product with a large transaction amount, the transaction data is processed in the multi-thread parallel execution mode, and therefore, after a transaction corresponding to the transaction batch identifier is acquired, the transaction state of the transaction needs to be detected. The transaction state comprises three states of pending, processing and processed.
In step 606, if the transaction status of the transaction corresponding to the transaction batch identifier is processed, the transaction corresponding to the transaction batch identifier is rolled back.
When only the transaction batch identifier is received and the transaction state of the transaction corresponding to the transaction identifier is determined to be processed, rolling back the batch transaction corresponding to the received transaction batch identifier: changing the data written into the database in the execution process of the transaction corresponding to the transaction batch identifier into the data before the transaction corresponding to the transaction batch identifier is executed; and modifying the transaction state corresponding to the transaction batch identifier into a to-be-processed state.
In this embodiment, a rollback method that can perform partial rollback on transaction products with large transaction amounts is provided, and a rollback method that can perform full rollback on received batch transaction data is also provided, so that the system can perform rollback in different ways, and flexibility of transaction rollback is improved.
In one embodiment, as shown in fig. 7, another transaction rollback method is provided, comprising:
Similarly, the transaction rollback instruction may be an instruction for presetting timing start, or an instruction initiated by an operator in real time through a terminal; the rollback mode includes full rollback and partial rollback.
And 704, if the rollback mode is partial rollback which carries the screening condition and the transaction batch identifier, screening out target transactions which meet the screening condition from the transactions corresponding to the transaction batch identifier.
The screening conditions are based on actual transaction requirements. In this embodiment, the filtering condition includes at least one of two dimensions of a transaction product and a transaction user. Specifically, the expression form of the trading product may be a trading product name, a trading product type, or a trading product identifier, etc.; the expression form of the transaction user can be a transaction product holding user name, or a transaction product holding user identifier and the like. It should be noted that the screening conditions are not limited to the screening conditions of two dimensions of the transaction product and the transaction user listed in this embodiment, and in this embodiment, screening conditions of other dimensions may also be formulated according to actual transaction requirements.
The transaction batch identifier is used to uniquely identify the received batch transaction. In this embodiment, the number of received transaction batch identifiers is not limited, and may be one or more.
At step 706, the transaction status of the target transaction is detected.
For transaction products with large transaction amount, transaction data are processed by adopting a multi-thread parallel execution mode, so that after target transactions meeting the screening condition are found out from received batch transactions, the transaction state of the target transactions needs to be detected, and corresponding subsequent operations are carried out according to the transaction state.
At step 708, if the transaction status of the target transaction is processed, the target transaction is rolled back.
The transaction state comprises three states of pending, processing and processed. The rollback may be performed only after the target transaction execution is complete.
And step 710, if the rollback mode is partial rollback with transaction data, analyzing the transaction data to obtain a transaction product identifier, a transaction application date and a transaction product holding user identifier.
The transaction data is data generated by the user directly or indirectly conducting trading transaction operations through the internet. For example, the fund transaction data includes: the fund holds user identification, fund transaction type, fund identification, fund transaction application date, transaction amount or user hold share, etc.
And 712, if the transaction product identification is consistent with the preset additional transaction product identification in comparison and the transaction application date is earlier than the current date, searching for the transaction to be rolled back which is stored in the database, identical to the transaction product identification and the transaction product holding user identification and has the transaction application date later than the transaction application date.
If the trade product identification is consistent with the preset additional trade product identification, the trade product is a trade product capable of conducting trade data additional record operation, and the trade application date is earlier than the current date of the system, and the current additional record of the trade data of the trade product is needed. Then, after the transaction data of the transaction product is additionally recorded in the system, all transaction data after the additional transaction application date need to be rolled back before executing the additional transaction data.
At step 714, the transaction to be rolled back is rolled back.
The processing of the transaction data with a small transaction amount adopts a single-thread execution mode, so that before the additional recording transaction is executed, the transaction data to be rolled back needs to be directly rolled back after the transaction to be rolled back is determined.
In step 716, if the rollback mode is full rollback with the transaction batch identifier, the transaction corresponding to the transaction batch identifier is obtained.
When only the transaction batch identifier is received, it is indicated that the transaction corresponding to the transaction batch identifier needs to be rolled back in a full amount currently.
At step 718, the transaction status of the transaction corresponding to the transaction batch identifier is detected.
For a transaction product with a large transaction amount, a multi-thread parallel execution mode is adopted to process transaction data, so that after a transaction corresponding to a transaction batch identifier is acquired, the transaction state of the transaction needs to be detected.
In step 720, if the transaction status of the transaction corresponding to the transaction batch identifier is processed, the transaction corresponding to the transaction batch identifier is rolled back.
And after the transaction corresponding to the received transaction batch identifier is obtained and the transaction state of the transaction corresponding to the transaction identifier is determined to be processed, rolling back the transaction in full.
In this embodiment, a rollback method for performing partial rollback on a transaction product with a large transaction amount, a rollback method for performing partial rollback on a transaction product with a small transaction amount due to entry-added transactions, and a rollback method for performing full rollback on received batch transaction data are provided, so that the system can perform rollback in different ways according to the transaction amount of the transaction product, and flexibility of transaction rollback is improved.
