Question

spring 怎么获取response

Answer 1

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();
