Spring jdbctemplate，数据源，transactionManager

Question

For a test, i have a abstract class.

public abstract class BaseTestClass

  private JdbcTemplate jdbcTemplate;

  @Autowired
  public void setDataSource(DataSource dataSource)
  {
  this.setJdbcTemplate(new JdbcTemplate(dataSource));
  }
  ...
}


@Transactional
@ContextConfiguration(locations = {"/spring/test/test-dao-context.xml"})
public class TestUser extends BaseTestClass{
...
}

In test-dao-context.xml file, i have my transaction manager and datasource.

SetDataSource is never called, so i get a null pointerException when i try to do a test.

You need to run you test with an appropriate runner which is SpringJUnit4ClassRunner for Spring driven tests. Otherwise nothing will get injected anywhere as there is no Spring Container managing all the instances.

Check Spring Unit Testing for details.
