我正在使用基于注释的弹簧配置并尝试测试我的基于 JPA 的 DAO。配置后，当我运行测试时，会抛出以下错误。即使在 Test 类中创建了 Bean 配置，我也不知道为什么找不到 IPartnerDao。

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = { JPAConfig.class })
public final class PartnerDaoTest {

    @Configuration
    static class ContextConfiguration {

        @Bean
        public IPartnerDao getParDao() {
            return new PartnerDao();
        }
    }

    @Autowired
    private IPartnerDao parDao;

    @Test
    public void testFindPartnerWithAddress() throws Exception {
        Partner partner = parDao.findPartnerWithAddress(1L);
        assertNotNull(partner);
    }
}

DAO 类

@Repository
@Transactional(readOnly = true)
public class PartnerDao implements IPartnerDao {

    private static Logger logger = Logger.getLogger(PartnerDao.class.getName());

    @PersistenceContext
    private EntityManager em;

    public PartnerDao() {

    }


    /* (non-Javadoc)
     * @see main.java.net.bornil.persistence.service.IPartnerDao#find(java.lang.Long)
     */
    @Override
    public Partner findPartnerWithAddress(Long id) {
        if (logger.isDebugEnabled()) {
            logger.debug("Partner ID : " + id);
        }

        Query query = em.createQuery("select p from Partner p join fetch p.addressSet where p.id = :id");
        query.setParameter("id", id);

        return (Partner) query.getSingleResult();
    }

}

合作伙伴界面

@Service
public interface IPartnerDao {

    public Partner findPartnerWithAddress(Long id);

}

JPAConfig 类

@Configuration
// @EnableLoadTimeWeaving
@EnableTransactionManagement
@PropertySource({ "classpath:jdbc.properties" })
public class JPAConfig {

    @Autowired
    Environment env;

    @Bean
    DataSource getJdbcDataSource() {

        String jdbcUrl = env.getProperty("jdbc.url");
        String username = env.getProperty("jdbc.username");
        String password = env.getProperty("jdbc.password");

        return new DriverManagerDataSource(jdbcUrl, username, password);
    }

    @Bean
    public PlatformTransactionManager getTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(getEntityManagerFactoryBean().getObject());
        return transactionManager;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean getEntityManagerFactoryBean() {
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setDataSource(getJdbcDataSource());
        factory.setPackagesToScan(new String[] { "main.java.net.bornil.persistence.entity" });

        HibernateJpaVendorAdapter hjva = new HibernateJpaVendorAdapter();
        hjva.setGenerateDdl(false);
        hjva.setShowSql(true);
        hjva.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");

        factory.setJpaVendorAdapter(hjva);
        return factory;
    }

}

确保您的JPAConfig.class.

@ComponentScan("package.containing.PartnerDao")
public class JPAConfig{

}

还可以尝试将测试添加到由ContextLoader

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, 
   classes = { JPAConfig.class, PartnerDaoTest.class })
public final class PartnerDaoTest {

/** tests**/
}
