Jdbc 返回空列表但 SQL 查询成功获取数据 [Spring]

Question

I am trying to execute this query:

@Override
public UserInfo get(Long id) {
    String sql = "SELECT * FROM users WHERE id = ? ";
    List<UserInfo> list = jdbcTemplate.query(sql,new UserInfoMapper(),id);
    return list.get(0);
}

but jdbc return empty list and I get exception at return line. But if try to execute directly though the console it returns: Query, Answer

Query was executed with id 1 and retured correct anwser; But in method its returned this

I couldn't find any same questions so that may be point at my inattention to something. But I can't see any problem that may cause this. Thanks in advance;

Updated 1 Changing code to

@Override
public UserInfo get(Long id) {
    String sql = "SELECT * FROM users WHERE id = ? ";
    List<UserInfo> list = jdbcTemplate.query(sql, new Object[] {id},new UserInfoMapper());
    return list.get(0);
}

resulted in same: result Updated 2

@Override
public UserInfo mapRow(ResultSet resultSet, int i) throws SQLException {
    UserInfo info = new UserInfo();
    info.setId(resultSet.getLong("id"));
    info.setFirstname(resultSet.getString("firstname"));
    info.setMiddlename(resultSet.getString("middlename"));
    info.setLastname(resultSet.getString("lastname"));
    info.setUsername(resultSet.getString("username"));
    info.setPassword(resultSet.getString("password"));
    info.setEmail(resultSet.getString("email"));
    info.setMobilephone(resultSet.getString("mobilephone"));
    info.setPosition(resultSet.getString("position"));
    return info;
}
public class UserInfo {
    private Long id;
    private String firstname;
    private String middlename;
    private String lastname;
    private String username;
    private String password;
    private String email;
    private String mobilephone;
    private String position;

    public UserInfo() {
    }
}

Getter and setters for each field is there but I think there is no need to show them up.

Answer 1

Check user credentials that you are using to connect database from your application and the user credentials in console. And also check owner schema , table owner schema in your application.
