有两个接口
RequestBodyAdvice和ResponseBodyAdvice 在spring4中新添加的两个接口
RequestBodyAdvice接口
该接口是在获取@RequestBody参数数据之前进行处理的
public interface RequestBodyAdvice {
boolean supports(MethodParameter methodParameter, Type targetType,
Class<? extends HttpMessageConverter<?>> converterType);
Object handleEmptyBody(Object body, HttpInputMessage inputMessage, MethodParameter parameter,
Type targetType, Class<? extends HttpMessageConverter<?>> converterType);
HttpInputMessage beforeBodyRead(HttpInputMessage inputMessage, MethodParameter parameter,
Type targetType, Class<? extends HttpMessageConverter<?>> converterType) throws IOException;
Object afterBodyRead(Object body, HttpInputMessage inputMessage, MethodParameter parameter,
Type targetType, Class<? extends HttpMessageConverter<?>> converterType);
}
ResponseBodyAdvice接口
该接口是在消息体被HttpMessageConverter消息解析器写入之前执行的
public interface ResponseBodyAdvice<T> {
boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType);
T beforeBodyWrite(T body, MethodParameter returnType, MediaType selectedContentType,
Class<? extends HttpMessageConverter<?>> selectedConverterType,
ServerHttpRequest request, ServerHttpResponse response);
}
