@RequestBody的使用

@RequestBody是spring mvc中的一個標籤，用來接收json格式的字符串數據，而不是json對象，所以json對象需要使用JSON.stringify()方法來將對象轉化爲字符串。然後將dataType的值寫爲json，此外contentType的值寫爲application/json

<script type="text/javas\cript">  
    $(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>

控制層的代碼爲：

  @RequestMapping(value = "saveUser", method = {RequestMethod.POST }}) 
    @ResponseBody  
    public void saveUser(@RequestBody List<User> users) { 
         userService.batchSave(users); 
    }
