[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

The descriptions with reference to the terms "one embodiment", "a specific embodiment", "some embodiments", "for example", etc. mean that the specific features, structures or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be appropriately adjusted as needed.

[0025] Figure 1 FIG. 1 is a schematic diagram of a transaction processing system across new and old systems in an embodiment of the present invention. Figure 1 As shown, the system includes:

[0026] The transaction splitting and combining device 101 is used to extract multiple routing record elements of the transaction sent by the calling end; split the transaction according to the multiple routing record elements; send the split multiple atomic transactions to the distribution device; receive the transaction result returned by the distribution device and feed it back to the calling end;

[0027] The distribution device 102 is used to query the routing table to obtain the target system corresponding to the routing record element of each split atomic transaction; send each split atomic transaction to the corresponding target system; receive the transaction result returned by the target system and feed it back to the transaction splitting and combining device; the target system is a new system or an old system;

[0028] The linkage device 103 is used to receive a transaction data processing request sent by the first system and send it to a message queue; wherein the second system monitors the message queue, obtains the transaction data processing request and performs transaction data processing to obtain a transaction data processing result; wherein the first system is a new system and the second system is an old system, or the first system is an old system and the second system is a new system.

[0029] In the embodiment of the present invention, while supporting the new and old systems synchronously, the high-performance operation of the new and old systems is maintained, and the transactions of the new and old systems can maintain their original integrity.

[0030] During the specific implementation, the new system and the old system coexist. Figure 2 This is another schematic diagram of the transaction processing system across the new and old systems in an embodiment of the present invention. In one embodiment, the system also includes an account verification device 104, which is used to perform account verification between the new system and the old system according to a preset period based on the transaction data processing results of the linkage device to check whether there is a unilateral transaction.

[0031] Figure 3 This is a schematic diagram of a transaction processing system across new and old systems in an embodiment of the present invention. In specific implementation, the routing record element may be an account number. For example, in a transfer transaction, a transfer-out account number, a transfer-in account number, a fee account number, etc. may be involved. The atomic transactions corresponding to these accounts may be distributed in the new system and the old system respectively. In this case, the original uploaded transaction needs to be split into three atomic transactions according to the transfer-out account number, the transfer-in account number, and the fee account number, namely, a transfer-out transaction, a transfer-in transaction, and a fee transaction, wherein each atomic transaction has a corresponding target system. For example, if the target system corresponding to the account number of the transfer-out transaction and the fee transaction is the new system, and the account number involved in the transfer-in transaction is found to be an account number of the old system after routing calculation, it needs to be routed to the old system for processing.

[0032] In addition, the transaction interface format of each atomic transaction needs to be organized according to the format of the target system (such as fixed-length package, XML, JSON, etc.).

[0033] In one embodiment, the transaction splitting and combining device is further used for:

[0034] For each atomic transaction, determine whether the atomic transaction requires the transaction result of the preceding atomic transaction;

[0035] If so, after receiving the transaction result of the preceding atomic transaction, the atomic transaction is sent to the distribution device;

[0036] If not, the atomic transaction is sent to the distribution device synchronously with the preceding atomic transaction.

[0037] The above embodiment is aimed at the transaction result of the previous atomic transaction that may be involved in a non-first atomic transaction. For example, if the transfer-in transaction is the transfer-out amount + the interest involved in the transfer-out amount, then after the transfer-out transaction is completed, the return amount and interest need to be filled into the transfer-in account and then distributed.

[0038] In one embodiment, the transaction splitting and combining device is further used for:

[0039] When the returned transaction result is a transaction failure, the reverse transaction of the preceding atomic transaction of the atomic transaction corresponding to the transaction failure is sent to the distribution device; the transaction result of the reverse transaction returned by the distribution device is received and fed back to the calling end;

[0040] The distribution device is also used to: receive the transaction result of the reverse transaction returned by the target system and feed it back to the transaction splitting and combining device.

[0041] In the above embodiment, the reversal of atomic transactions is achieved.

[0042] In one embodiment, the transaction splitting and combining device is further used for:

[0043] After receiving the transaction results of all atomic transactions after the upward transaction is split, the transaction results of all atomic transactions are spliced ​​together and fed back to the calling end.

[0044] In the above embodiment, the purpose of splicing is to send the result corresponding to the transaction to the calling end, rather than sending it in the form of the transaction result of all atomic transactions.

[0045] In the embodiment of the present invention, most of the data in the old and new systems are processed separately, and some data will not be divided according to the granularity of the switch between the old and new systems. For example, the total quota table, etc., these data will be synchronized with one side as the main one. For such data, the system needs to be linked and processed.

[0046] Therefore, the linkage device can receive a transaction data processing request sent by the first system and send it to a message queue; wherein the second system monitors the message queue, obtains the transaction data processing request and performs transaction data processing to obtain a transaction data processing result; wherein the first system is a new system and the second system is an old system, or the first system is an old system and the second system is a new system.

[0047] That is, if the data is mainly from the old system, the transaction data processing request needs to be sent to the old system through the linkage device. In the old system, if the data is mainly from the new system, it will be processed in reverse. The linkage device uses a two-way message queue for asynchronous transmission, which reduces the coupling relationship between the two systems. Due to performance considerations, the processing results are not returned to the new system or the old system, but can be sent to the account reconciliation device. Based on the transaction data processing results of the linkage device, the account reconciliation between the new system and the old system is performed according to a preset period (for example, every day) to check whether there is a unilateral transaction. If so, feedback can be given to the business personnel.

[0048] In summary, in the device proposed in the embodiment of the present invention, the transaction splitting and combining device is used to extract multiple routing record elements of the transaction sent by the calling end; split the transaction according to the multiple routing record elements; send the multiple atomic transactions after splitting to the distribution device; receive the transaction result returned by the distribution device and feedback to the calling end; the distribution device is used to query the routing table to obtain the target system corresponding to the routing record element of each atomic transaction after splitting; send each atomic transaction after splitting to the corresponding target system; receive the transaction result returned by the target system and feedback to the transaction splitting and combining device; the target system is a new system or an old system; the linkage device is used to receive the transaction data processing request sent by the first system and send it to the message queue; wherein the second system monitors the message queue, obtains the transaction data processing request and performs transaction data processing to obtain the transaction data processing result; wherein the first system is the new system and the second system is the old system, or the first system is the old system and the second system is the new system. In the above process, while synchronously supporting the new and old systems, the high-performance operation of the new and old systems is maintained, and the transactions of the new and old systems can maintain their original integrity.

[0049] The embodiment of the present invention further proposes a transaction processing method across new and old systems, the principle of which is similar to that of the transaction processing system across new and old systems, and will not be described in detail here.
