在SpringMVC中获取request对象的几种方式

1. 注解法
   

   @Autowiredprivate HttpServletRequest request;

   
   
   
2. 配置一个监听器(Spring)
   

   <listener><listener-class>org.springframework.web.context.request.RequestContextListener</listener-class><listener/><pre name="code" class="java">

   
   

   HttpServletRequest requet = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();

   
   
   
   
   
3. 最直接的方法
   public String sendEmail(HttpServletRequest request, HttpServletResponse response)
