类 PackageResponseBodyAdvice

java.lang.Object

com.github.yt.web.result.PackageResponseBodyAdvice

所有已实现的接口:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware, org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice<Object>

@Order(value=200)
 @ControllerAdvice
public class PackageResponseBodyAdvice
extends Object
implements org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice<Object>, org.springframework.context.ApplicationContextAware

1.返回体拦截器 实现ResponseBodyAdvice接口的supports和beforeBodyWrite方法 2.异常拦截器 @ExceptionHandler作用的handleExceptions方法

ApplicationContextAware 的作用是可以获取spring管理的bean

正常返回和异常返回分别被该类处理 拦截返回结果或者异常包装成HttpResultEntity
