java直接獲取request、response

 

 

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(!!!!!!---比較重要,能夠憑空獲取)(獲取當前線程的request ，response)

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