@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
