更新ステートメント(UpdateUser)を実行しようとすると、MyBatisでこの例外が発生します。

私が使用しているデータ型ユーザーは次のようになります。
public class User {
private String firstName = "";
private String lastName = "";
private String personCode = "";
private Date birthDate = new Date();
private Gender gender = Gender.MALE;
private String email = "";
private String password = "";
private UserState userState = UserState.UNAPPROVED;
public User() {
}
もちろん、適切なゲッターとセッターと一緒に。
mybatisのUserMapper.javaインターフェイスは次のようになります。
public interface UserMapper {
public User getUserByEmail(String email);
public void addUser(User user);
public void removeUser(String email);
public int getNumberOfUsers();
public int userExists(String email);
public boolean updateUser(@Param ("oldUser") User oldUser, @Param("newUser") User newUser);
public Map<String, User> getAllUsers();
}
そして、私のUserMapper.xmlは次のようになります。
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper

前述したように、updateUserが呼び出されると例外がスローされます。奇妙なことに、ここで整数に関連するものは何も表示されません。つまり、1つのフィールドを更新するだけでテストを試みたということです。それはすべて同じです。クエリが完全に削除された場合にのみ例外が発生しません。クエリエラーまたは何かエラーが発生します...
助言がありますか?前もって感謝します。
