 第一种、参数

@RequestMapping("/test")
@ResponseBody
public 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

ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
  
    HttpServletRequest request = servletRequestAttributes.getRequest();
    HttpServletResponse response = servletRequestAttributes.getResponse();
