How to get insertion id from database? Spring boot

Question

i am trying to get insertion id from postgres database. My code now looks like:

String sql = "INSERT INTO ACCOUNT (name) VALUES (?);";
        jdbcTemplate.update(sql, account.name);

id is generated automatically.

How should I change this code, that it would return the row id of the inserted account?

You can use SimpleJdbcInsert to insert values and get generated keys from operation.

public class JdbcActorDao implements ActorDao {

private JdbcTemplate jdbcTemplate;
private SimpleJdbcInsert insertActor;

public void setDataSource(DataSource dataSource) {
    this.jdbcTemplate = new JdbcTemplate(dataSource);
    this.insertActor = new SimpleJdbcInsert(dataSource)
            .withTableName("t_actor")
            .usingGeneratedKeyColumns("id");
}

public void add(Actor actor) {
    Map<String, Object> parameters = new HashMap<String, Object>(2);
    parameters.put("first_name", actor.getFirstName());
    parameters.put("last_name", actor.getLastName());
    Number newId = insertActor.executeAndReturnKey(parameters);
    actor.setId(newId.longValue());
 }  
}
