spring filter httpmethd

1. < filter >     
   
2.   < filter-name > HiddenHttpMethodFilter </ filter-name >   
3.     < filter-class > org.springframework.web.filter.HiddenHttpMethodFilter </ filter-class >   
4. </ filter >

• 在web.xml中配置以上，就可以拦截delete和put请求
• <!-- 浏览器不支持put,delete等method,由该filter将/blog?_method=delete转换为标准的http delete方法 -->
