Answer 1

@ResourceMapping("queryRackLists")
public RpcResult<Rack> queryRackLists(@JsonParam("rackOlds")
List<RackVo> rackList, ErrorContext error) {
    RpcResult<Rack> dataResult = new RpcResult<Rack>();
    try {
        List<Rack> list = rackBo.getRackList(rackList);
        dataResult.setDataList(list);
    } catch (Exception e) {
        logger.error("queryRackLists rackList={}, err : ", JSON.toJSONString(rackList), e);
        dataResult.setSuccess(false);
        if (e instanceof ServiceException) {
            addError(error, e);
            dataResult.setInfo(e.getMessage());
        } else {
            addError(error, ErrorCode.Query_Error);
            dataResult.setInfo(ErrorCode.Query_Error.getMsg());
        }
    }
    return dataResult;

}

类似于这种，传入JSONArray，用list来接收。

前台拼接成json，传到后台转成bean的list。http://blog.csdn.net/zhangdai...

<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> 

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