1.user实体类定义了一个Date类型数据
代码语言：javascript
复制package entity;
import lombok.Data;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.*;
/**
* zt
* 2020/10/9
* 21:22
*/
@Data
public class User {
private String username;
private String password;
private String email;
private Integer age;
//默认是yyyy/MM/dd
// @DateTimeFormat
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date birthday;
}
2.在springmvc.xml开启注解驱动（一般在开启包扫描就开启注解驱动）
代码语言：javascript
复制<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 包扫描-->
<context:component-scan base-package="controller"></context:component-scan>
<!-- 开启注解驱动-->
<mvc:annotation-driven/>
<!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
这里的Date类型数据是自定义yyyy-MM-dd格式，如果是默认的就不需要配置注解驱动也能运行
代码语言：javascript
复制//默认是yyyy/MM/dd
@DateTimeFormat
