Spring mvc 构造RESTful URL 详细讲解

1. /blog/1  HTTP GET =>    得到id = 1的blog  
2. /blog/1  HTTP DELETE => 删除 id = 1的blog  
3. /blog/1  HTTP PUT  =>   更新id = 1的blog  
4. /blog     HTTP POST =>   新增BLOG  

1. @RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)  
2. public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) {  
3.     blogManager.removeById(id);  
4.     return new ModelAndView(LIST_ACTION);  
5. }  

1. @RequestMapping(value="/blog/{blogId}/message/{msgId}",method=RequestMethod.DELETE)  
2. public ModelAndView delete(@PathVariable("blogId") Long blogId,@PathVariable("msgId") Long msgId,HttpServletRequest request,HttpServletResponse response) {  
3. }  

1. <!-- 该servlet为tomcat,jetty等容器提供,将静态资源映射从/改为/static/目录，如原来访问 http://localhost/foo.css ,现在http://localhost/static/foo.css -->  
2. <servlet-mapping>  
3.     <servlet-name>default</servlet-name>  
4.     <url-pattern>/static
