SpringMVC(八) RequestMapping HiddenHttpMethodFilter

標籤：map   隱藏   cti   spring   htm   integer   imp   lte   sys   

SpringMVC隱藏方法：

使用PUT和DELETE方法。預設HTML支援GET和POST方法。通過HiddenHttpMethodFilter將POST轉成PUT和DELETE方法。

1、將HiddenHttpMethodFilter配置到web.xml中

    <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>    

2、控制器代碼

package com.tiekui.springmvc.handlers;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;@Controllerpublic class HiddenHttpMethodFilterTest {    @RequestMapping(value="testHiddenHttpMethod/{id}",method=RequestMethod.DELETE)    public String testHiddenHttpMethodDelete(@PathVariable("id") Integer id){        System.out.println("Delete" + id);        return "success";    }        @RequestMapping(value="testHiddenHttpMethod/{id}",method=RequestMethod.PUT)    public String testHiddenHttpMethodPut(@PathVariable("id") Integer id){        System.out.println("PUT" + id);        return "success";    }    }

 

3、視圖代碼

    <form action="testHiddenHttpMethod/1" method="post">        <input type="hidden"  name="_method" value="PUT">        <input type="submit" value="testHiddenHttpMethodPUT">    </form>    <br>    <form action="testHiddenHttpMethod/1" method="post">        <input type="hidden"  name="_method" value="DELETE">        <input type="submit" value="testHiddenHttpMethodDelete">    </form>
