springmvc 将post转换为delete，put

摘要: springmvc 将post转换为delete，put

web.xml

<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>

页面

<form:form action="/xxx/xxx" method="put">
</form:form>

生成的页面代码会添加一个hidden的_method=put,并于web.xml中的HiddenHttpMethodFilter配合使用，在服务端将post请求改为put请求

<form id="userInfo" action="/xxx/xxx" method="post">
<input type="hidden" name="_method" value="put"/>
</form>

controller方法

@RequestMapping(value="/{id}",method=RequestMethod.PUT)
@RequestMapping(value="/{id}",method=RequestMethod.DELETE)
