Technical Field
The invention relates to the field of computer software, in particular to a transaction connection establishing method and device based on middleware.
Background
In the transaction, a connection with the server needs to be established first.

And if the connection with the server is established, executing the query instruction and receiving a corresponding query return result. And after receiving the result, if the operation instructions in the transaction are all executed, releasing the connection with the server. When a plurality of transactions exist, it is time-consuming to frequently establish connection with the server, and a middleware mode is adopted, wherein the middleware is established on the server, and the middleware establishes a connection pool. When there is a transaction, a connection can be taken from the connection pool of the middleware to directly establish connection with the server.
The transaction can contain a plurality of state operation instructions, and if one connection is taken from the connection pool of the middleware and the plurality of state operation instructions in the transaction are processed in sequence, the connection cannot be released for a long time and is kept in a connection state all the time. When a plurality of transactions need to be processed, a plurality of connections in the connection pool are always kept in a connection state, so that the connection pool occupies a larger memory, and the memory occupied by the connection pool is suddenly expanded, thereby affecting the transaction processing speed.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flow diagram of a middleware-based transaction connection establishment method according to an embodiment of the invention. As shown in fig. 1, the method for establishing a transaction connection based on middleware specifically includes the following steps:
and step S101, receiving a kth state operation instruction of the transaction, and establishing a kth connection with the server.
The transaction is a complete execution unit and comprises n state operation instructions, and the n state operation instructions have a front-back execution sequence. Wherein n is a natural number. And when the transaction is executed, n state operation instructions are executed in sequence. Take the k-th status operation command of the received transaction as an example, where n is not less than k.
And receiving a kth state operation instruction of the transaction, and establishing a kth connection with the server, wherein the kth connection is a free connection selected from a connection pool and used as the kth connection with the server. The connection pool is provided by middleware arranged on the server, and a plurality of connections exist in the connection pool and are all connected with the server. The kth connection connects the middleware to the server.
Step S102, obtaining and analyzing the 1 st item result to the k-1 st item result corresponding to the 1 st item state operation to the k-1 st item state operation of the transaction, and respectively reconstructing the 1 st item state operation instruction to the k-1 st item state operation instruction of the transaction.
After the kth connection with the server is established, the 1 st result to the k-1 st result corresponding to the 1 st state operation to the k-1 st state operation of the transaction are obtained. And storing the 1 st result to the (k-1) th result in the middleware, and acquiring the 1 st result to the (k-1) th result from the middleware. And analyzing the 1 st result to the k-1 st result, and reconstructing the 1 st state operation instruction to the k-1 st state operation instruction corresponding to the transaction. And during reconstruction, reversely acquiring the 1 st state operation instruction to the k-1 st state operation instruction according to the 1 st result to the k-1 st result, and completing reconstruction.

And step S104, receiving a kth item result corresponding to the kth state operation instruction returned by the server, saving the kth item result and releasing the kth connection.
And through the kth connection with the server, sequentially transmitting the reconstructed 1 st state operation instruction to the kth-1 st state operation instruction and the current kth state operation instruction to the server. Because the k state operation instructions in the transaction have a front-back execution relation, before the current k state operation instruction is executed, the server sequentially executes the 1 st state operation instruction to the k-1 st state operation instruction, and then executes the current k state operation instruction. After the server executes, since the 1 st to k-1 st results corresponding to the 1 st to k-1 st state operations have been previously saved, only the kth result corresponding to the kth state operation instruction returned by the server is received and saved this time, for example, the kth result may be saved in the middleware. When saving, the number of data in the k item result, the data length of the k item result, each data type of the k item result, the transaction ID, and the like, which are included in the k item result, are saved. The transaction ID is the identification of the transaction, and the transaction IDs of the results corresponding to the n state operation instructions in the transaction are consistent. And saving the kth item result and releasing the current kth connection. When releasing, for example, sending a connection release message to the server to put the kth connection back into the connection pool, so that the state of the kth connection is changed into an idle state.
And executing the steps to finish the operation corresponding to the current k state operation instruction. And circularly executing the steps until the operations corresponding to the n state operation instructions contained in the transaction are completed.
According to the transaction connection establishing method based on the middleware, provided by the invention, a kth state operation instruction of a transaction is received, and a kth connection with a server is established; acquiring and analyzing the 1 st result to the k-1 st result corresponding to the 1 st state operation to the k-1 st state operation of the transaction, and respectively reconstructing the 1 st state operation instruction to the k-1 st state operation instruction of the transaction; sequentially transmitting the reconstructed 1 st state operation instruction to the k-1 st state operation instruction and the k state operation instruction to the server through the k connection; and receiving a kth item result corresponding to the kth state operation instruction returned by the server, storing the kth item result and releasing the kth connection. According to the scheme, the 1 st state operation to the k-1 st state operation before the k state operation instruction are reconstructed according to the obtained 1 st result to the k-1 st result, and the reconstructed state operation instruction and the k state operation instruction are sequentially transmitted to the server, so that the integrity of the whole transaction is ensured. Meanwhile, the connection establishment, the reconstruction of the state operation instruction and the transmission of the reconstructed state operation instruction are all based on the middleware, and the middleware is arranged on the server, so that compared with the prior method that the state operation instruction is directly transmitted to the server, the speed is higher, the time spent is shorter, and the problems of the sudden expansion of a connection pool memory, low execution efficiency and the like caused by the fact that the transaction connection is occupied for a long time are effectively solved.
Fig. 2 is a flowchart illustrating a transaction connection establishment method based on middleware according to another embodiment of the present invention.
When k =1, the middleware-based transaction connection establishing method specifically includes the steps shown in fig. 2:
step S201, receiving the 1 st state operation instruction of the transaction, and establishing the 1 st connection with the server.
Step S202, the 1 st state operation instruction is transmitted to the server through the 1 st connection.

Receiving a 1 st state operation instruction of a transaction, and selecting a free connection from a connection pool of the middleware as a 1 st connection with the server so as to establish the 1 st connection with the server. And transmitting the 1 st state operation instruction to the server through the 1 st connection. The 1 st state operation instruction of the transaction is directly executed by the server because no other state operation instruction exists before the 1 st state operation instruction. Receiving the 1 st result corresponding to the 1 st state operation instruction returned by the server, and storing the 1 st result in the middleware. When saving, the number of data in the 1 st result, the data length of the 1 st result, the data types of the 1 st result, the transaction ID, and the like, which are included in the 1 st result, are saved. The transaction ID is the identification of the transaction, and the transaction IDs of the results corresponding to the n state operation instructions in the transaction are consistent.
According to the transaction connection establishment method based on the middleware, provided by the invention, the 1 st state operation instruction of a transaction is received, and the 1 st connection with a server is established; transmitting the 1 st state operation instruction to a server through the 1 st connection; receiving the 1 st result corresponding to the 1 st state operation instruction returned by the server, saving the 1 st result and releasing the 1 st connection. And after the stored 1 st result can be analyzed, reconstructing to generate a 1 st state operation instruction so as to be sequentially transmitted to the server with a k state operation instruction later, and ensuring the integrity of the whole transaction during execution. Meanwhile, the connection establishment and the state transmission operation instructions are all based on the middleware, and the middleware is arranged on the server, so that the speed is higher and the time spent is shorter compared with the original method that the state operation instructions are directly transmitted to the server, thereby effectively solving the problems that the internal memory of a connection pool is burst and the execution efficiency is low due to the fact that the business connection is occupied for a long time.
Fig. 3 is a flowchart illustrating a transaction connection establishment method based on middleware according to another embodiment of the present invention. As shown in fig. 3, the method for establishing a transaction connection based on middleware specifically includes the following steps:

The connection pool is provided by middleware arranged on the server, and a plurality of connections exist in the connection pool and are all connected with the server. The kth connection connects the middleware to the server.
Step S302, according to the transaction ID carried by the kth state operation instruction, searching the saved item 1 result to item k-1 result which are consistent with the transaction ID.
And searching a result of the transaction ID which is consistent with the transaction ID in the result stored by the middleware according to the transaction ID carried by the kth state operation instruction, namely the result from the item 1 to the item k-1 of the transaction.
The middleware may have multiple results stored simultaneously for multiple different transactions, with different transactions having different transaction IDs. In the two embodiments of the method described above, it has been described that after the receiving server returns the result, the result is saved. The transaction ID is included in the saved results. And searching a plurality of results of the transaction corresponding to the kth state operation instruction according to the transaction ID included in the results and the transaction ID carried by the kth state operation instruction.
Step S303, the 1 st result to the k-1 st result corresponding to the 1 st state operation to the k-1 st state operation of the transaction are obtained and analyzed, and the 1 st state operation instruction to the k-1 st state operation instruction of the transaction are respectively reconstructed.

Step S305, receiving the kth item result corresponding to the kth state operation instruction returned by the server, saving the kth item result and releasing the kth connection.
The above steps can refer to steps S102-S104 in the embodiment of fig. 1, and are not described herein again.
In step S306, it is determined whether k is equal to n.
If k is equal to n, i.e. the k-th operation instruction is the last operation instruction of the transaction, step S306 is executed, otherwise, steps S301 to S305 are executed in a loop, and the operation instruction of the next transaction is received continuously.
Step S307, returning the kth result corresponding to the kth state operation instruction of the transaction to the initiator of the transaction.
And returning the kth result corresponding to the kth state operation instruction of the transaction to the initiator of the transaction to finish the execution of the transaction.

And when k = n, namely when the last state operation instruction of the transaction is received, returning the k item result corresponding to the k item state operation instruction of the transaction to the initiator of the transaction. And finishing the processing of the whole transaction, and returning a corresponding transaction processing result to the initiator of the transaction. The method comprises the steps that the state operation instructions of connection establishment, reconstruction and reconstruction transmission are all based on the middleware, and the middleware is arranged on a server, so that the method is higher in speed and less in spent time compared with the method that the state operation instructions are directly transmitted to the server, and the problems that the business connection is occupied for a long time, the memory of a connection pool is burst, the execution efficiency is low and the like are effectively solved. Meanwhile, before the kth state operation instruction is executed, the 1 st state operation instruction to the kth-1 st state operation instruction are all reconstructed and are sequentially transmitted to the server and executed by the server, so that the integrity of the whole transaction is ensured.
Fig. 4 shows a functional block diagram of a middleware based transaction connection setup apparatus according to an embodiment of the present invention. As shown in fig. 4, the middleware-based transaction connection establishing apparatus includes the following modules:
the connection module 410 is adapted to receive a kth state operation instruction of the transaction and establish a kth connection with the server.
The transaction is a complete execution unit and comprises n state operation instructions, and the n state operation instructions have a front-back execution sequence. Wherein n is a natural number. When executed, the transaction executes n state operation instructions in sequence. The connection module 410 is illustrated by receiving the kth state operation instruction of the transaction, where n is not less than k.
The connection module 410 receives the kth state operation instruction of the transaction, and establishes the kth connection with the server, where the kth connection is a connection selected by the connection module 410 from the connection pool as the kth connection with the server. The connection pool is provided by middleware arranged on the server, and a plurality of connections exist in the connection pool and are all connected with the server. The kth connection connects the middleware to the server.
The reconstruction module 420 is adapted to obtain and analyze the 1 st to k-1 st results corresponding to the 1 st to k-1 st state operations of the transaction, and reconstruct the 1 st to k-1 st state operation instructions of the transaction, respectively.
After the connection module 410 establishes the kth connection with the server, the reconstruction module 420 obtains the 1 st to the k-1 st results corresponding to the 1 st to the k-1 st state operations of the transaction. The 1 st result to the (k-1) th result are stored in the middleware, and the reconstruction module 420 acquires the 1 st result to the (k-1) th result from the middleware. The reconstruction module 420 analyzes the 1 st to k-1 st results, and reconstructs the 1 st to k-1 st state operation instructions corresponding to the transaction. When the reconstruction module 420 reconstructs the data, the 1 st to the k-1 st state operation instructions are reversely acquired according to the 1 st to the k-1 st results, and the reconstruction is completed.
The result module 430 is adapted to sequentially transmit the reconstructed 1 st to k-1 st state operation instructions and the k state operation instruction to the server through the k connection; and receiving a kth item result corresponding to the kth state operation instruction returned by the server, storing the kth item result and releasing the kth connection.
The result module 430 sequentially transmits the reconstructed 1 st state operation instruction to the k-1 st state operation instruction and the current k state operation instruction to the server through the k connection with the server. Because the k state operation instructions in the transaction have a front-back execution relation, before the server executes the current k state operation instruction, the server sequentially executes the 1 st state operation instruction to the k-1 st state operation instruction, and then executes the current k state operation instruction. After the server executes, since the 1 st to k-1 st results corresponding to the 1 st to k-1 st state operations have been previously saved, the result module 430 only receives the kth result corresponding to the kth state operation instruction returned by the server for saving, for example, the kth result may be saved in the middleware. When saving, the result module 430 saves the number of data in the kth item result, the data length of the kth item result, each data type of the kth item result, the transaction ID, and the like, which are included in the kth item result. The transaction ID is the identification of the transaction, and the transaction IDs of the results corresponding to the n state operation instructions in the transaction are consistent. The result module 430 saves the kth result and releases the kth connection this time. When the result module 430 releases, for example, a connection release message is sent to the server to place the kth connection back into the connection pool, so that the state of the kth connection is changed to an idle state.
And executing the modules to complete the operation corresponding to the current state operation instruction. And circularly executing the modules until the operations corresponding to the n state operation instructions contained in the transaction are completed.
When k =1, the connection module 410 is further adapted to receive the 1 st state operation instruction of the transaction, select a free connection from the connection pool of the middleware as the 1 st connection with the server, and thereby establish the 1 st connection with the server. The results module 430 is further adapted to communicate the 1 st state operation instruction to the server over the 1 st connection. The 1 st state operation instruction of the transaction is directly executed by the server because no other state operation instruction exists before the 1 st state operation instruction. The result module 430 receives the 1 st result corresponding to the 1 st state operation instruction returned by the server, saves the 1 st result, and releases the 1 st connection. The 1 st result is saved in the middleware. When the result module 430 saves the 1 st result, the number of data in the 1 st result, the data length of the 1 st result, the data types of the 1 st result, the transaction ID, and the like included in the 1 st result are saved. The transaction ID is the identification of the transaction, and the transaction IDs of the results corresponding to the n state operation instructions in the transaction are consistent.
According to the transaction connection establishing device based on the middleware, provided by the invention, a kth state operation instruction of a transaction is received, and a kth connection with a server is established; acquiring and analyzing the 1 st result to the k-1 st result corresponding to the 1 st state operation to the k-1 st state operation of the transaction, and respectively reconstructing the 1 st state operation instruction to the k-1 st state operation instruction of the transaction; sequentially transmitting the reconstructed 1 st state operation instruction to the k-1 st state operation instruction and the k state operation instruction to the server through the k connection; and receiving a kth item result corresponding to the kth state operation instruction returned by the server, storing the kth item result and releasing the kth connection. According to the scheme, the 1 st state operation to the k-1 st state operation before the k state operation instruction are reconstructed according to the obtained 1 st result to the k-1 st result, and the reconstructed state operation instruction and the k state operation instruction are sequentially transmitted to the server, so that the integrity of the whole transaction is ensured. Meanwhile, the connection establishment, the reconstruction of the state operation instruction and the transmission of the reconstructed state operation instruction are all based on the middleware, and the middleware is arranged on the server, so that compared with the prior method that the state operation instruction is directly transmitted to the server, the speed is higher, the time spent is shorter, and the problems of the sudden expansion of a connection pool memory, low execution efficiency and the like caused by the fact that the transaction connection is occupied for a long time are effectively solved.

As shown in fig. 5, compared with fig. 4, the middleware-based transaction connection establishing apparatus further includes the following modules:
the searching module 440 is adapted to search the saved item 1 result to item k-1 result which are consistent with the transaction ID according to the transaction ID carried by the kth state operation instruction.
The searching module 440 searches for a result that the transaction ID is consistent with the transaction ID in the result stored in the middleware, that is, the result of item 1 to item k-1 of the transaction, according to the transaction ID carried in the kth state operation instruction.
The middleware may have multiple results stored simultaneously for multiple different transactions, with different transactions having different transaction IDs. As described in the above device embodiment, the result module 430 saves the result after the receiving server returns the result. The transaction ID is included in the saved results. The searching module 440 may search multiple results of the transaction corresponding to the kth state operation instruction according to the transaction ID included in the result and the transaction ID carried by the kth state operation instruction.
