spring mvc注解回忆

重点内容

@Transactional 回滚
@ResponseBody 返回
@RequestMapping 跳转
@PathVariable获得请求url中的动态参数

>

controller方法中的用法

value = “/outDepot/{userId}”, produces = MediaType.APPLICATION_JSON_VALUE,
method=RequestMethod.POST,params={“product_id”,”out_num”})
跳转地址、提交类型、提交方式、必须有的参数

 @RequestMapping( value = "/outDepot/{userId}", produces = MediaType.APPLICATION_JSON_VALUE,
 method=RequestMethod.POST,params={"product_id","out_num"}) 
 public String getLogin(@PathVariable("userId") String userId,  
     String product_id,String out_num){  
     System.out.println("User Id : " + userId);  
     return "hello";  
 }
