REST请求方式-使用hiddenhttpmethodfilter实现增删改用同一个resultmapping

1. web.xml中配置如下

<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. 在jsp的form表单中增加一个隐藏input标签

<input type="hidden" name="_method" value="PUT" />
