本文解析了一个关于MyBatis框架中构造函数引发的异常问题，并提供了具体的错误信息及解决方案。异常出现在尝试实例化User类时，原因是构造函数参数类型不匹配。文章最后给出了移除特定构造函数作为解决办法。

异常原因：

public User(Long id, String userName, String userPhone, String userEmail, String userPwd, String pwdSalt, Date createTime, Date modifyTime, Short isDelete) {
    this.id = id;
    this.userName = userName;
    this.userPhone = userPhone;
    this.userEmail = userEmail;
    this.userPwd = userPwd;
    this.pwdSalt = pwdSalt;
    this.createTime = createTime;
    this.modifyTime = modifyTime;
    this.isDelete = isDelete;
}
