我尝试@RequestMapping(value = "/test", method = RequestMethod.POST)但是是错误的

代码是

 @Controller
 public class HelloWordController {
 private Logger logger = LoggerFactory.getLogger(HelloWordController.class);

 @RequestMapping(value = "/test", method = RequestMethod.POST)
 public String welcome() {
  logger.info("Spring params is welcome");
  return "/WEB-INF/jsp/welcome";
 }

}

web.xml是

<servlet>
<description>This is Spring MVC DispatcherServlet</description>
<servlet-name>SpringMVC DispatchServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
  <description>SpringContext</description>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath*:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>



  <servlet-mapping>
<servlet-name>SpringMVC DispatchServlet</servlet-name>
<url-pattern>/</url-pattern>

和springmvc.xml是

index.jsp是

<form action="<%=request.getContextPath() %>/test" method="post">
<input type="submit" value="submit"> 
</form>

我输入提交botton浏览器是错误的
