spring 怎么获取response

Posted 2023-05-02

参考技术A 1.最简单方式：参数

[java] view plain copy
@RequestMapping("/test")
@ResponseBody
public void saveTest(HttpServletRequest req, HttpServletResponse resp)　　

2.加入监听器，然后再controller里面获取
(1)web.xml相应位置插入
[html] view plain copy
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

[java] view plain copy
HttpServletRequest req = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
HttpServletResponse resp = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();

Java-Spring-获取Request,Response对象

第一种、参数

@RequestMapping("/test")
@ResponseBodypublic void saveTest(HttpServletRequest req, HttpServletResponse resp){　　
}

第二种、注解

@Autowired  
private  HttpServletRequest request;

第三种、上下文获取

1、在web.xml配置监听器

<listener>
      <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class></listener>

2、程序使用

HttpServletRequest req = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
HttpServletResponse resp = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();

 

根据个人喜好使用

推荐第三种
