解决后端需要接收Date类型参数，前端传过来的是字符串的问题。

在pojo中对特定的date类型属性加了以下配置
@DateTimeFormat来控制入参，@JsonFormat来控制出参

复制    
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
    private Date payTime;

参考教程

Spring Boot jackson（Date类型入参、格式化，以及如何处理null）

 

elementui需要配合得表单为：

<el-date-picker v-model="dataForm.startTime" type="datetime" placeholder="选择日期" value-format="yyyy-MM-dd HH:mm:ss"
:disabled="disable">
</el-date-picker>
