REST架构中的PUT、DELETE请求如何实现?

---

web.xml

<!-- 将POST请求转化为DELETE或者是PUT 要用_method指定真正的请求参数 -->
<filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

html

<form:form action="/admin/users/update" method="post" commandName="user" role="form">
    <input type="hidden" name="_method" value="put"/>

---

Controller

@RequestMapping(value = "/update", method = RequestMethod.PUT)
  or
@PutMapping(value = "/update")
