SessionFactory bean在Junit测试中初始化，但没有在@SprinBootApplication中初始

Question

我有一个集成了hibernate的SpringBoot应用程序。我使用Spring连接了hibernate属性。当我在Junit测试中使用sessionFactory时，我可以做所有的CRUD操作，但当我运行SpringBootApplication时，即，当我运行Main类时，其中包含@SpringBootApplication;最后得到一个

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} exception.

你知道怎么解决这个问题吗?

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class GreetingRepositoryDAOTest {
    @Resource
    private BaseRepository greetingRepositoryImpl;
    @Test
    public void test() {
        System.out.println(((Greeting) greetingRepositoryImpl.findOne(1L)).getText());
        Greeting gr = new Greeting();
        gr.setText("Third Text");
        greetingRepositoryImpl.save(gr);
    }
}
@RestController
@SpringBootApplication
public class Application {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
    @RequestMapping("/")
    String home() {
        return "Hello World!";
    }
}

applicationContext

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    <context:property-placeholder location="classpath:application.properties" />
</beans>

DAO类

@Repository
public class BaseDAO {
    @Autowired
    private SessionFactory sessionFactory;
    public Criteria createCriteria(Class<?> clazz, String alias) {
        return currentSession().createCriteria(clazz, alias);
    }
    public Session currentSession() {
        return sessionFactory.getCurrentSession();
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

Spring Boot默认不加载bean applicationContext.xml。您可以通过在Application类中添加注释来实现:

@ImportResource("classpath:applicationContext.xml")

这将把BaseDAO添加到Spring Boot应用程序上下文中，但是看起来你的代码中有更多的问题:

• 没有必要为application.properties创建PropertyPlaceholder -默认情况下它是由Spring Boot加载的
• 看看Spring Data JPA以及它如何与Spring Boot一起工作-它可能会简化您的Hibernate配置(我看到您有另一个很可能不需要的hibernateContext.xml)。
• 考虑放弃xml bean配置以支持@Configuration类。
