I get id generated by database (MSSQL) after insert like below, imports:

  import org.springframework.jdbc.core.BeanPropertyRowMapper;
  import org.springframework.jdbc.core.JdbcTemplate;
  import org.springframework.jdbc.core.RowMapper;
  import org.springframework.jdbc.core.SqlParameter;
  import org.springframework.jdbc.core.SqlReturnResultSet;
  import org.springframework.jdbc.core.simple.SimpleJdbcCall;

and the code snippet:

    final String INSERT_SQL = "INSERT INTO [table]\n"
            + " ([column_1]\n"
            + " ,[column_2])\n"
            + " VALUES\n" +
            " (?, ?)";

    Connection connection = jdbcTemplate.getDataSource().getConnection();
    PreparedStatement preparedStatement = connection.prepareStatement(INSERT_INVOICE_SQL, Statement.RETURN_GENERATED_KEYS);
    preparedStatement.setString(1, "test 1");
    preparedStatement.setString(2, "test 2");

    preparedStatement.executeUpdate();
    ResultSet keys = preparedStatement.getGeneratedKeys();

    if (keys.next()) {
        Integer generatedId = keys.getInt(1); //id returned after insert execution
    }
