Question

我遇到了Hades Synyx库的问题。我正在尝试进行一些DAO测试。我的测试看起来如下所示，但是当我尝试使用TestNG运行它时，我已经获得了NPE。为什么春天不注射PacientDAO？

@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class PacientDAOTest {

@Autowired
private PacientDAO dao;

@Test
public void shouldAddPacient() {
    Pacient pacient = new Pacient();
    pacient.setName("x");
    pacient.setSecondName("xx");
    pacient.setLastName("xxx");
    pacient.setBirthDate(new Date(2000, 10, 10));
    pacient.setPesel(1111111111);
    pacient.setSex(Sex.FEMALE);
    pacient.setEmail("aaza@asd.pl");
    pacient.setContactNumber(123456L);
    dao.save(pacient);
    Assert.assertEquals(pacient, dao.readByPrimaryKey(pacient.getId()));
    }
}

和我的pacientDAO：

public interface PacientDAO extends GenericDao<Pacient, Long> {

@Query("Select * from dietetyk_pacients where name = :name")
    public Pacient getByName(@Param("name") String name);
}

的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

您应该实施

public interface PacientDAO

在某些

中

public class PacientDAOImpl

然后，要使此类成为注入候选者，必须将bean定义添加到 applicationContext.xml 描述符 OR 使用@Repository注释对其进行注释并使用<context:component-scan base-package="your.package"/>

在您的描述符中激活基于注释的扫描
