上一篇以简单介绍了一点RESTFUL URL
Spring MVC 3.0中一个重大的变化是增加RESTFUL URL功能,可以通过下面的方式访问,如:
/userManagerContoller/1 |
HTTP GET => |
得到id = 1的user |
/userManagerContoller/1 |
HTTP DELETE => |
删除 id = 1的user |
/userManagerContoller/1 |
HTTP PUT => |
更新id = 1的user |
/userManagerContoller/1 |
HTTP POST => |
新增user |
模板中的参数可以定义多个
@RequestMapping("/welcome/{param}/{sex}")
springmvc restful实现
springmvc的resturl是通过@RequestMapping及@PathVariable annotation提供的,通过如@RequestMapping(value="/userManagerContoller/{id}",method=RequestMethod.DELETE)
即可处理/userManagerContoller/1 的delete请求.
- <span style="">@RequestMapping(value="/userManagerContoller/{id}",method=RequestMethod.DELETE)
- public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,
- HttpServletResponse response) {
- userManager.removeById(id);
- return new ModelAndView(LIST_ACTION);
- }</span>
@RequestMapping @PathVariable如果URL中带参数,则配合使用,如:
- <span style="">@RequestMapping @PathVariable如果URL中带参数,则配合使用,如:
- @RequestMapping(value="/userManagerContoller/{userId}/message/{msgId}",method=RequestMethod.DELETE)
- public ModelAndView delete(@PathVariable("userId") Long userId,@PathVariable("msgId")
- Long msgId,HttpServletRequest request,HttpServletResponse response) {
-
- }</span>
