解决Spring框架的Dao层改用@Repository注解，无法使用JdbcDaoSupport的问题

@Repository
public class UserDetailsDaoImpl extends JdbcDaoSupport implements UserDetailsDao {

	@Autowired
	private DataSource dataSource;

	@PostConstruct
	private void initialize() {
		setDataSource(dataSource);
	}
	
}

@Repository("testDao")
public class TestDaoImpl extends JdbcDaoSupport implements BaseDao{

  @Autowired
  TestDaoImpl(DataSource dataSource) {
    setDataSource(dataSource);
  }
}

Or

@Repository("testDao")
public class TestDaoImpl extends JdbcDaoSupport implements BaseDao{

  @Autowired
  TestDaoImpl(JDBCTemplate template) {
    setJdbcTemplate(template);
  }
}
