Question

我正在与SpringBoot和Hibernate ORM合作。对于单元测试，我正在使用junit。仅运行测试用例时出现上述异常。

TestClass：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes={ MainApp.class })
public class TestEmplService {

    @Autowired EmployeeService eService;


    @BeforeClass
    public static void beforeTest() {
        System.out.println("Starting test engine");
    }

    @AfterClass
    public static void AfterTest() {
        System.out.println("Terminating test engine");
    }

    @Test
    public void  getEmployeeById() {
        Employee empObj = eService.findById(2);
        assertNotNull(empObj);
        System.out.println(empObj.toString());
    }
}

实施类别：

@Repository
public class EmployeeServiceImpl extends QueryHelper implements EmployeeService{

     @Autowired
     private SessionFactory sessionFactory;

    public EmployeeServiceImpl() {
        super("/queries/employee.yml");
        System.out.println(sessionFactory);
    }

    @Override

    public Employee findById(int id) {
        try {
        System.out.println("Find by id   "+sessionFactory); 
        Session session = sessionFactory.getCurrentSession();
        System.out.println("Find by id   "+session);    
        Employee employee = (Employee)session.get(Employee.class, id);
        //emailService.sendMessage("vrushak.k@sonata-software.com", "Searched Data", employee.toString());
        return employee;
        }
        catch(Throwable t) {
        throw new RepositoryException(t);   
        }
    }
}

Employee Service只是具有上述方法声明的接口。当我仅运行TestCase时，出现上述异常。正常执行效果很好。

MainApp.java

@SpringBootApplication()
@EnableAutoConfiguration
public class MainApp {

    public static void main(String... argsa) {
        // TODO Auto-generated method stub
    SpringApplication.run(MainApp.class, argsa);
    }

    @Bean()
    public EmployeeService employeeServices(){
        return new EmployeeServiceImpl();
    }

}

主应用程序类包含employeeService个注入，该注入在弹簧开始时立即加载。我想这个异常是在会话工厂的某个地方引起的。

HibernateConfig.java

@Configuration
public class HibernateConfig {
    @Value("${db.driver}")
    private String DB_DRIVER;

    @Value("${db.password}")
    private String DB_PASSWORD;

    @Value("${db.url}")
    private String DB_URL;

    @Value("${db.username}")
    private String DB_USERNAME;

    @Value("${hibernate.dialect}")
    private String HIBERNATE_DIALECT;

    @Value("${hibernate.show_sql}")
    private String HIBERNATE_SHOW_SQL;

    @Value("${hibernate.hbm2ddl.auto}")
    private String HIBERNATE_HBM2DDL_AUTO;

    @Value("${entitymanager.packagesToScan}")
    private String ENTITYMANAGER_PACKAGES_TO_SCAN;



    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);
        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", HIBERNATE_DIALECT);
        hibernateProperties.put("hibernate.show_sql", HIBERNATE_SHOW_SQL);
        hibernateProperties.put("hibernate.hbm2ddl.auto", HIBERNATE_HBM2DDL_AUTO);
        sessionFactory.setHibernateProperties(hibernateProperties);
        return sessionFactory;
    }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(DB_DRIVER);
        dataSource.setUrl(DB_URL);
        dataSource.setUsername(DB_USERNAME);
        dataSource.setPassword(DB_PASSWORD);
        return dataSource;
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory().getObject());
        return txManager;
    }
}

上面的配置负责加载会话工厂和数据源。

请让我知道我要去哪里错了？
