REST請求方式-使用hiddenhttpmethodfilter實現增刪改用同一個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表單中增加一個隱藏input標籤

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