为什么Java的date 插入MySQL会报这样的错？

错误提示：

Hibernate: insert into telecom.admins (name, loginname, loginpassword, phone, email, enrolldate) values (?, ?, ?, ?, ?, ?)

Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: could not insert: [com.tantan.ssh.domain.Admin];SQL state [01004]; error code [0];

Caused by: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data truncated for column 'enrolldate' at row


SQL语句：

SQL code:

create table admins(
id int primary key auto_increment,
name varchar(20),
loginname varchar(20) unique,
loginpassword varchar(20),
phone varchar(20),
email varchar(30),
enrolldate date
)type=InnoDB default charset=utf8;





Java测试代码：

Java code:

public void testSave(){
Admin admin=new Admin();
admin.setName("tantan");
admin.setLoginname("longling");
admin.setLoginpassword("longling");
admin.setEmail("tantanqin2006@126.com");
admin.setPhone("13594693567");
//字符编码问题
admin.setEnrolldate(new Date());
