详解element-ui日期时间选择器的日期格式化问题

2020-06-14 06:14:31易采站长站整理

最近在做vue+element-ui的后台管理页面,其中用到了DateTimePicker来选择日期时间,但是在将数据传回后台的过程中遇到了一些令人头疼的问题,在此记录一下解决方案,以免日后再次遇到。

前端页面

前端代码


submitForm(formName) {
this.$refs[formName].validate((valid) => {
let url = 'http://localhost:8088/pethospital/order-record'
let data = qs.stringify({
title: this.orderForm.title,
hospitalId: this.orderForm.hospitalId,
orderDate: this.orderForm.orderDate,
orderType: this.orderForm.orderType,
petVariety: this.orderForm.petVariety,
mobilePhone: this.orderForm.mobilePhone,
supplement: this.orderForm.supplement
})
if (valid) {
axios.post(url, data)
.then(response => {

}).catch(error => {
this.$message({
message: '错误:' + error,
type: true
})
})
} else {
this.$message('验证错误:请确认信息是否填写完整')
}
});
}

实体类代码


private Long id;
private String title;
private Integer hospitalId;
private Date orderDate;
private Integer orderType;
private String petVariety;
private String mobilePhone;
private String supplement;

Controller代码


@PostMapping("/order-record")
public CommonResult addOrderRecord(OrderRecordDO orderRecordDO) throws ParseException {
System.out.println("添加的预约记录:" + orderRecordDO);
orderRecordDOMapper.insertSelective(orderRecordDO);
return null;
}

控制台输出

Field error in object ‘orderRecordDO’ on field ‘orderDate’: rejected value [2019-04-10 10:00:00]; codes [typeMismatch.orderRecordDO.orderDate,typeMismatch.orderDate,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [orderRecordDO.orderDate,orderDate]; arguments []; default message [orderDate]]; default message [Failed to convert property value of type ‘java.lang.String’ to required type ‘java.util.Date’ for property ‘orderDate’; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.util.Date] for value ‘2019-04-10 10:00:00’; nested exception is java.lang.IllegalArgumentException]]

看了控制台的输出信息,大概知道是前端将日期当做String类型传输的,但是我们后台定义日期用的是Date类型,因此这里报的转换异常。本来我想用SimpleDateFormat来转换的,但是觉得这样很麻烦,然后在网上查找相关资料发现可以有更简单的方法。
