JS之JSON字符串到後臺用Java轉換成List實體類

重點：JAVA之JSON字符串轉換LIST實體類

​​​​​​​List<ExamListInVO> list = new ArrayList<ExamListInVO>();
list = JSONObject.parseArray(strResult, ExamListInVO.class);

下面展示實例

 

1、靜態頁面

<div class="form-group">
	<label class="col-sm-3 control-label">個人簡歷：</label>
	<div class="col-sm-8">
		<table class="table table-bordered" id="crList">
			<tr>
				<td class="active">
					<label class="control-label">起止年月</label>
				</td>
				<td class="active">
					<label class="control-label">在何處任何職（工種）</label>
				</td>
			</tr>
			<tr data-type="cr">
				<td class="active">
					<input id="startEndDate" name="startEndDate" class="form-control" type="text">
				</td>
				<td class="active">
					<input id="workContent" name="workContent" class="form-control" type="text">
				</td>
			</tr>
			<tr data-type="cr">
				<td class="active">
					<input id="startEndDate" name="startEndDate" class="form-control" type="text">
				</td>
				<td class="active">
					<input id="workContent" name="workContent" class="form-control" type="text">
				</td>
			</tr>
			<tr data-type="cr">
				<td class="active">
					<input id="startEndDate" name="startEndDate" class="form-control" type="text">
				</td>
				<td class="active">
					<input id="workContent" name="workContent" class="form-control" type="text">
				</td>
			</tr>
		</table>
	</div>
</div>

2、js封裝參數並提交

//獲取工作經歷部分的列表數據
function getContractResumeData(){
	var contractResumeArray=[];
    var tr = $("#crList tr");
    tr.each(function(index){
        var isCrTableTr = $(this).attr("data-type");
        if(isCrTableTr !== "cr"){
            return ;
		}
        var tempCr = {};
        tempCr["startEndDate"]=$(this).find("input[name='startEndDate']").val();
        tempCr["workContent"]=$(this).find("input[name='workContent']").val();
        contractResumeArray.push(tempCr);
    });
    return contractResumeArray;
}

//提交表單
function saveSubmit() {
	var signupFormData=$('#signupForm').serialize();
	var crStr=JSON.stringify(getContractResumeData());
	$.ajax({
		cache : true,
		type : "POST",
		url : "/contract/contractInfo/update",
		data : signupFormData+"&crStr="+crStr,// 你的formid
		async : false,
		error : function(request) {
			parent.layer.alert("Connection error");
		},
		success : function(data) {
			if (data.code == 0) {
				parent.layer.msg("操作成功");
				parent.reLoad();
				var index = parent.layer.getFrameIndex(window.name); // 獲取窗口索引
				parent.layer.close(index);

			} else {
				parent.layer.alert(data.msg)
			}
		}
	});
}

3、java後端接收json字符串並轉爲List<實體>

/**
 * 保存
 */
@ResponseBody
@PostMapping("/save")
@RequiresPermissions("contract:contractInfo:add")
public R save( ContractPartyDO contractParty,String crStr){
	String contractId=UUID.randomUUID().toString().replaceAll("-","");
	contractParty.setContractId(contractId);
	int res2=contractPartyService.save(contractParty);
	
	//保存乙方工作經歷
	List<ContractResumeDO> crList = new ArrayList<ContractResumeDO>();
	crList=JSONObject.parseArray(crStr, ContractResumeDO.class);
	int count=0;
	ContractPartyDO cpb=contractPartyService.getByContractId(contractId);
	for (ContractResumeDO cr : crList) {
		//如果獲取到該行工作經歷爲空，也要保存，留出空白行方便用戶以後的編輯。
		cr.setPartyBId(cpb.getId());
		count+=contractResumeService.save(cr);
	}
	if(res1>0 && count==crList.size()){
		return R.ok();
	}
	return R.error();
}
