SpringBoot 日期时间参数匹配问题
前端使用Element-UI的 el-time-picker,设置value-format=timestamp
前端打印参数如下,timestamp类型
Chrome报错截图:
400错误
后台错误:

核心错误:
Failed to convert from type [java.lang.String]
to type [java.util.Date]
for value ‘1561336773000’; nested exception is java.lang.IllegalArgumentException
无法将字符串类型的值转换为Date类型
解决方法:
1. 前端处理,修改参数格式为”yyyy-MM-dd HH:mm:ss”
2. 后端Controller 增加自定义处理
/**
* 自定义时间格式处理
*/
@InitBinder
public void initBinder(WebDataBinder binder) {
//转换日期
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
// CustomDateEditor为自定义日期编辑器
binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
