Java-Spring-獲取Request,Response對象

第一種、參數

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

第二種、注解

@Autowired  
private  HttpServletRequest request;  

第三種、上下文獲取

1、在web.xml配置監聽器

<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();
