spring MVC之Spring MVC3.0的RESTFul方式的访问

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/1	HTTP GET =>	得到id = 1的blog
/blog/1	HTTP DELETE =>	删除 id = 1的blog
/blog/1	HTTP PUT  =>	更新id = 1的blog
/blog	HTTP 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(value="/blog/{id}",method=RequestMethod.DELETE)
 public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,
    HttpServletResponse response) {
    blogManager.removeById(id);
     return new ModelAndView(LIST_ACTION);
}

@RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)
public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,
	HttpServletResponse response) {
	blogManager.removeById(id);
	return new ModelAndView(LIST_ACTION);
}

 

 

@RequestMapping @PathVariable如果URL中带参数，则配合使用，如:

@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) {

}
