我有一个spring应用程序（不是springboot），其中我使用spring数据jpa和基于注解的java配置。我正在尝试单元测试（junit 4）一个存储库片段，在该片段中我创建了自定义保存方法，但无法正确加载运行测试所需的上下文和bean：

[main] INFO org.springframework.test.context.support.DefaultTestContextBootstrapper - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener, org.springframework.test.context.support.DirtiesContextBeforeModesTestExecutionListener, org.springframework.test.context.support.DependencyInjectionTestExecutionListener, org.springframework.test.context.support.DirtiesContextTestExecutionListener, org.springframework.test.context.transaction.TransactionalTestExecutionListener, org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener, org.springframework.test.context.event.EventPublishingTestExecutionListener]

我应该如何适当地加载应用程序上下文？
用户DAO测试

@ActiveProfiles("dev")
@ContextConfiguration(loader=AnnotationConfigContextLoader.class, classes= {RepositoryConfig.class})
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class UserDaoTests {

private UserRepository userRepository;

@Autowired
private DataSource dataSource;

@Autowired
public void setUserRepository (UserRepository userRepository) {
    this.userRepository = userRepository;
}

private User user1 = new User("user", "userpass", true);

@Before
public void init() {
    System.out.println("Before running tests: init");
    JdbcTemplate jdbc = new JdbcTemplate(dataSource);
    jdbc.execute("delete from sec.authorities");
    jdbc.execute("delete from sec.users");
}

@Test
public void testExists () {
    userRepository.save(user1);
    System.out.println("Users created, test exists");
    assertTrue("User should exist", userRepository.existsByUsername("user"));
    assertFalse("User should not exist", userRepository.existsByUsername("abcdefghj"));
}
}

存储配置

@Configuration
@ComponentScan("com.example.app.dao")
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = {
        "com.example.app.dao"
}, entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager")
public class RepositoryConfig {

    @Profile("production")
    @Bean(name = "dataSource")
    public DataSource dataSource() {
        JndiDataSourceLookup lookup = new JndiDataSourceLookup();
        return lookup.getDataSource("java:jboss/datasources/postgresqlDS");
    }

    @Profile("dev")
    @Bean(name = "dataSource")
    public DataSource jdbcDataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setConnectionProperties(jdbcProperties().toString());
        return dataSource();
    }

   @Bean
   public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
      LocalContainerEntityManagerFactoryBean emf 
        = new LocalContainerEntityManagerFactoryBean();
      emf.setDataSource(dataSource());
      emf.setPackagesToScan(new String[] { "com.example.app.dao" });

      JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
      emf.setJpaVendorAdapter(vendorAdapter);
      emf.setJpaProperties(hibernateProperties());

      return emf;
   }

    private final Properties hibernateProperties() {
       //...
    }

    private final Properties jdbcProperties() {
        Properties jdbcProperties = new Properties();
        jdbcProperties.setProperty("driverClassName", "${jdbc.driver}");
        jdbcProperties.setProperty("url", "${jdbc.url}");
        jdbcProperties.setProperty("username", "${jdbc.username}");
        jdbcProperties.setProperty("password", "${jdbc.password}");
        return jdbcProperties;
    }

    @Bean
    public TransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        transactionManager.setDataSource(dataSource());
        return transactionManager;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptiontranslator() {
        return new PersistenceExceptionTranslationPostProcessor();
    }
}

用户存储库

public interface UserRepository extends CustomizedSave<User>, CrudRepository<User, Long> {

    Optional<User> findByUsername(String username);
    Boolean existsByUsername(String username);
}

自定义saveimpl

@Repository
public class CustomizedSaveImpl implements CustomizedSave<User>{    
    @Autowired
    private BCryptPasswordEncoder passwordEncoder;

    @PersistenceContext
    EntityManager em;

    public CustomizedSaveImpl() {
        System.out.println("successfully loaded users DAO");
    }

    public User save (User user) {
        //...
    }   
}
