创建User时，调用的构造函数是Users user = new Users(username, userpass, nickname, Integer.parseInt(age), gender, email,phone, new Date(), new Date(), new Date(), 0);

而实际的构造函数是Users(String name, String userpass, String nickname, Integer age, String gender, String phone, String email, Date createTime, Date updateTime, Date lastLogin, Integer userStatus)

phone 和 email 的位置错了

而提供的sql语句，phone VARCHAR(13) COMMENT '联系方式',
email VARCHAR(20) COMMENT '用户邮箱',

phone是13是字符，email是20个字符，那么当填的email大于13个的时候，程序运行就会报错了，这个user根本插入不到数据库

你检查一下数据库中phone字段定义的是多长的，再检查对照一下你插入的数据是不是超过了字段长度~~ 

祝学习愉快！

    你把要插入的数据改短一点，之前插入10位，现在改为5位试下可以吗？
