Description

Method and device for uniformly processing response message, computer equipment and storage medium

Technical Field

The invention relates to the technical field of Spring MVC development, in particular to a method and a device for uniformly processing response messages, computer equipment and a storage medium.

Background

In the Spring MVC development process, most companies use a front-end and back-end separated application mode, the front end accesses the back-end service, and except for a normal returned result, the situations that a service code is abnormal, a server cannot find a request and the like can also occur. The formats of the data response messages returned to the front end under different conditions are not consistent, if the front end is required to analyze the result types, the workload of the front end is increased undoubtedly, and a bigger problem is that: the data formats of all response messages cannot be expected.

In the prior art, it is common practice to capture exceptions using the annotations @ exceptinonhandler and @ controlleraddress.

Referring to fig. 2, the exception from Service to artifact may be sent to the exception class defined by @ exception handler for processing, and then a response message with a uniform format is returned. However, since the @ exceptinonhandler cannot handle the abnormality of the Filter layer (Filter pre and Filter after in fig. 2), when the request of the front end is abnormal in the Filter layer, the front end may receive a response message in a different data format.

and filling the abnormal type and the abnormal information of the request into an abnormal type space and an abnormal information space in the response message template respectively, thereby generating the response message with a uniform format.

S4, if detecting that the request is abnormal between Service and afterCompletion, processing the request abnormality by a preset annotation, wherein the format of the response message generated by the preset annotation is the preset format.

In a specific implementation, if it is detected that an exception occurs between Service and afterCompletion of a request, a preset annotation is used to process the exception of the request, wherein a format of a response message generated by the preset annotation is the preset format.

In one embodiment, the preset annotation is the annotation @ exceptinonhandler.

The exception from Service to artifact can be sent to @ exception handler for processing, and then a response message is returned to the terminal. The format of the response message is the preset format.
