用于控制器的Spring自定义json消息转换器

Question

I would like to configure Custom JSON message converter which extending MappingJacksonHttpMessageConverter to work in Specific Controller. I have tried using AnnotationMethodHandlerAdapter but that would add it to every end point / controller.

Also FYI there are other custom message converters which are configured as AnnotationMethodHandlerAdapter .

Answer 1

Depends on your use-case.

Manual Conversion

As Sotirios wrote in his comment, the easiest way is if you marshall and unmarshall your requests manually.

Configure ObjectMapper

You can configure ObjectMapper to use different settings based on the class of the object it is (un)marshalling.

Spring Stuff

You can implement your own HandlerMethodReturnValueHandler and / or HandlerMethodArgumentResolver . These have access to handler method annotations. You can implement your own annotation and pretty much implement any custom conversion behavior.
