@RequestBody Spring MVC 示例

1.前端的访问请求

<script type="text/javascript">
    $(document).ready(function(){
        var saveDataAry=[];
        var data1={"userName":"test","address":"gz"};
        var data2={"userName":"ququ","address":"gr"};
        saveDataAry.push(data1);
        saveDataAry.push(data2);
        $.ajax({
            type:"POST",
            url:"user/saveUser",
            dataType:"json",
            contentType:"application/json",
            data:JSON.stringify(saveData),
            success:function(data){ 

            }
         });
    });
</script> 

2.前端的访问请求

// 方式一:
@RequestMapping(value = "/saveUser", method = {RequestMethod.POST }})
    @ResponseBody
    public void saveUser(@RequestBody List<User> users) {
         userService.batchSave(users);
    }
 // 方式二:
@RequestMapping(value = "/saveUser", method = {RequestMethod.POST }})
    @ResponseBody
    public void saveUser(@RequestBody List<Map<Object, Object>> maps) {
         userService.batchSave(users);
    } 

3.其他

[1].@RequestBody可以处理一下格式:

application/json
application/xml

[2].multipart/form-data的数据格式不能使用@RequestBody 处理
