spring MVC之Spring MVC3.0的RESTFul方式的访问

----------

?

下面的例子都是在基于Spring MVC 3.0基于注解的配置上进行的.?springmvc3.0中增加RESTful URL功能,可以通过下面的方式访问，如：

/blog/1HTTP GET =>得到id = 1的blog/blog/1HTTP DELETE =>删除 id = 1的blog/blog/1HTTP PUT ?=>更新id = 1的blog/blogHTTP POST =>新增BLOG

springmvc rest实现

springmvc的resturl是通过@RequestMapping及@PathVariable annotation提供的,通过如@RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)即可处理/blog/1 的delete请求.

??

@RequestMapping?@PathVariable如果URL中带参数，则配合使用，如: ??@RequestMapping(value="/blog/{blogId}/message/{msgId}",method=RequestMethod.DELETE) ??public?ModelAndView?delete(@PathVariable("blogId")?Long?blogId,@PathVariable("msgId")? ??????Long?msgId,HttpServletRequest?request,HttpServletResponse?response)?{ ?????? ??}??
