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

Java代码

 

1. @RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)   
2. public ModelAndView delete(@PathVariable
3.     HttpServletResponse response) {   
4.     blogManager.removeById(id);   
5. return new
6. }

@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:

Java代码

 

1. @RequestMapping @PathVariable如果URL中带参数，则配合使用，如:   
2. @RequestMapping(value="/blog/{blogId}/message/{msgId}",method=RequestMethod.DELETE)    
3. public ModelAndView delete(@PathVariable("blogId") Long blogId,@PathVariable("msgId")     
4.     Long msgId,HttpServletRequest request,HttpServletResponse response) {   
5.        
6. }
