隐藏注解里的http方法过滤器

web.xml里

<filter>

    <filter-name>HiddenHttpMethodFilter</filter-name>

    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

</filter>

<filter-mapping>

    <filter-name>HiddenHttpMethodFilter</filter-name>

    <servlet-name>spring</servlet-name>

</filter-mapping>

.java里

@RequestMapping(value = "/list", method = RequestMethod.GET)     //（就是这个method）
