SpringMVC隐藏方法：
使用PUT和DELETE方法。默认HTML支持GET和POST方法。通过HiddenHttpMethodFilter将POST转成PUT和DELETE方法。
1、将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、控制器代码
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;
@Controller
public 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、视图代码
<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>
