Service calling method and device

Abstract

The invention discloses a service calling method and device, and relates to the technical field of automatic programming. A specific embodiment of the method comprises the following steps: querying corresponding index information in a database according to a transaction element carried by a calling request, wherein the transaction element comprises a transaction identifier defined on the old service, and the index information comprises a service identifier of the new service; determining that index information exists in a database, and searching a corresponding new service interface according to an old service interface corresponding to the transaction identifier and a set interface inheritance relationship, wherein the interface inheritance relationship is used for interface conversion between the old service and the new service; and calling a corresponding new service according to the service identifier and the new service interface. According to the method, the transaction identifier of the old service is carried in the calling request, and the new service interface is determined based on the transaction identifier and the interface inheritance relationship when the new service is determined to be called, so that new service calling is realized, repeated development is not needed, and the development workload is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic program design, in particular to a method and device for invoking a service. Background technique [0002] In the process of structural transformation of the banking system, it is usually upgraded in batches. In this switching mode, there will be transactions under the state of the fusion architecture, and the transaction logic development under the state of the fusion architecture is required, especially when the service integration layer calls downstream atomic services, it needs to take into account both old services and new services. Among them, the functions of the new and old services are the same, but the protocols and specifications adopted are different. During development, application developers need to develop different transaction logics through different calling methods according to the called services. [0003] In the process of realizing the present invention, there are at least...

Problems solved by technology

[0004] The existing technology writes a set of transaction logic for the old service call and the new service call, which increases the complexity of the transaction logic, and there is a lot of repetitive development work, which increases the development workload; at the same time, because the existing technology is at the transaction level Differential processing of different calling methods, not scalable
