    Statement statement = connection.createStatement();
    ResultSet resultSet = statement.executeQuery("SELECT * FROM tablename");
} catch (SQLException e) {
    e.printStackTrace();
}
if (bean != null) {
    // 执行相关操作
} else {
    throw new NullPointerException("Bean is null");
}
try {
    List beans = jdbcTemplate.query("SELECT * FROM tablename", new BeanRowMapper());
} catch (DataAccessException e) {
    e.printStackTrace();
