Question

我有一个SpringBoot应用程序，它集成了hibernate。我使用Spring连接了hibernate属性。当我在Junit测试中使用sessionFactory时，我可以执行所有CRUD操作，但是当我运行SpringBootApplication时，即当我运行其中包含@SpringBootApplication的Main类时;它最终得到一个

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)}例外。

关于如何解决这个问题的任何想法？

@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!";
    }

}

的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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context.xsd">
    <import resource="hibernateContext.xml" />
    <context:component-scan base-package="com.deepaksp.springboot" />
    <context:property-placeholder location="classpath:application.properties" />
</beans>

hibernateContext

DAO课程

@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;
    }
}

默认情况下，Spring Boot不会加载bean applicationContext.xml。您可以通过以下方式注释Application类来完成此操作：

@ImportResource("classpath:applicationContext.xml")

这会将BaseDAO添加到Spring Boot应用程序上下文中，但看起来您的代码中存在更多问题：

无需为PropertyPlaceholder创建application.properties - 默认情况下由Spring Boot加载
看一下Spring Data JPA以及它如何与Spring Boot一起工作 - 它可以简化你的Hibernate配置（我看到你有另一个hibernateContext.xml很可能不需要）。
考虑删除xml bean配置以支持@Configuration类。

SessionFactory bean在Junit测试中初始化，但在@SprinBootApplication中没有
