SpringMvc 需要对返回的json做统一的处理时用

import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice; @ControllerAdvice public class MyResponseBodyAdvice implements ResponseBodyAdvice { @Override public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {

//写自己的统一处理逻辑

}
