The date selected using the el-date-picker date picker is of type string and is in the format pointed by the arrow
Solution one:
1. Add these two after this component to modify the format
<el-date-picker type="date" placeholder="选择日期" value-format="yyyy-MM-dd HH:mm:ss" format="yyyy-MM-dd"></el-date-picker>
2. Add annotations to the back-end entity class
Even if the front-end is of string type, the string is converted to LocalDateTime type through the format matching annotation tool that comes with json
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private LocalDateTime userBirthday;
Solution two:
Download a moment.js with npm
1、
npm install moment --save
2. Register in main.js
import moment from "moment";
//需要汉化
moment.locale('zh-cn');
Vue.prototype.$moment = moment;//赋值使用
let date = new Date(moment(this.userInfo.userBirthday).format('YYYY-MM-DD HH:mm:ss'));
