spring 中的自定义异常消息 云 function 部署在 aws-lambda

Question

I have a java project written using spring-cloud-function and deployed in aws-lambda.

I am trying to return a custom exception with some fields in the exception message body, something like"

{
  reason: <exception reason>
  code: <error code>
  <some other fields>
}

@ExceptionHandler, that is generally used in spring boot doesn't seem to work here.

I can return the exception in the required format by creating a class for building the exception message in required format but in that case the error code will always be 200 since it will not be an exception object per se. Instead it will be my custom error object.

Is there a way I can set this up so that the above required format of exception object is returned and correct error code can be returned too?

Thanks in advance

Answer 1

First, the exception has nothing to do with Spring Boot. It's part of spring-web, so yes it would not work here since sc-function is a general purpose framework, where the same function could be deployed and triggered via web, streaming, aws-lambda etc. .

Now, yes we had a problem returning JSON error (as you show) or object that represents the same, but that was fixed. So please update sc-function to 3.2.3.
