위 처럼 타입 핸들러를 셋팅 하면 된다고 하는데 안된다

import java.sql.CallableStatement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Timestamp;
import java.time.LocalDateTime;
import org.apache.ibatis.type.BaseTypeHandler;
import org.apache.ibatis.type.JdbcType;
import org.apache.ibatis.type.MappedTypes;

@MappedTypes(LocalDateTime.class)
public class LocalDateTimeTypeHandler extends BaseTypeHandler<LocalDateTime> {

    @Override
    public void setNonNullParameter(PreparedStatement ps, int i, LocalDateTime parameter, JdbcType jdbcType)
        throws SQLException {
        ps.setTimestamp(i, Timestamp.valueOf(parameter));
    }

    @Override
    public LocalDateTime getNullableResult(ResultSet rs, String columnName) throws SQLException {
        Timestamp timestamp = rs.getTimestamp(columnName);
        return getLocalDateTime(timestamp);
    }

    @Override
    public LocalDateTime getNullableResult(ResultSet rs, int columnIndex) throws SQLException {
        Timestamp timestamp = rs.getTimestamp(columnIndex);
        return getLocalDateTime(timestamp);
    }

    @Override
    public LocalDateTime getNullableResult(CallableStatement cs, int columnIndex) throws SQLException {
        Timestamp timestamp = cs.getTimestamp(columnIndex);
        return getLocalDateTime(timestamp);
    }

    private static LocalDateTime getLocalDateTime(Timestamp timestamp) {
        if (timestamp != null) {
            return timestamp.toLocalDateTime();
        }
        return null;
    }
}

위 처럼 @MappedTypes(LocalDateTime.class) 선언을 해주니 정상적으로 잘된다.
