未配置CurrentSessionContext

spring-boot

对不起，英语不好。我以spring-boot 1.1.8Encountered Exception 开始我的项目No CurrentSessionContext configured，然后进行了一些搜索，添加属性<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>可以解决此问题，但是

如何使用Java类配置此属性？

更新：我改为使用 Hibernate4.x 定义SessionFactory的 方式 ，但仍然遇到相同的错误，请帮忙！

使用java 1.8和speing boot 1.1.8

这是我的pom.xml

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>

SessionFactory sessionFactory;

public class UserServiceImpl implements UserService {
    public boolean isEmailExist(String email) {
        Session session = sessionFactory.openSession();
        // if I use getCurrentSession(), I will got the No Session found for current thread
        //Session session = sessionFactory.getCurrentSession();
        Criteria c = UserCriteria.isEmailExisting(session, email);
        List<UserInfo> usrs = c.list();
        session.close();
        if (0 == usrs.size() || usrs.isEmpty())
            return false;
        return true;
    }
}

@Controller
public class UserRegisterController {

    @RequestMapping("/doRegist")
    public void doRegister(HttpServletRequest request,
            HttpServletResponse response) {
        String usrEmail = request.getParameter("email");
        boolean exist = userService.isEmailExist(session, usrEmail);
        //todo
    }
}

WebApplicatoinStarter.java

@Configuration
@EnableAutoConfiguration
@ComponentScan("com.mytest")
public class WebApplicationStarter extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder application) {

    }

    public static void main(String[] args) throws Exception {
        ApplicationContext context = SpringApplication.run(WebApplicationStarter.class, args);
    }

    @Bean
    public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
        return hemf.getSessionFactory();
    }
}

您的hibernate配置和使用是错误的。您正在使用Spring甚至更好的Spring
Boot，但是您发布的内容非常努力地不使用这些框架，并尝试解决这些框架。我强烈建议使用Spring Boot并让它为您配置。

首先删除您的文件HibernateUtils，将其埋入深处，再也不要再看了。您还可以删除它，AppConfig因为Spring
Boot可以并且将会处理DataSource。

接下来application.properties，在src/main/resources目录中创建一个名为的文件，并将以下内容放入其中。

spring.datasource.url=jdbc:mysql://localhost/mysql
spring.datasource.username=root
spring.datasource.password=

这将自动DataSource为您配置一个。您不需要驱动程序，因为该驱动程序是根据您提供的网址推导出来的。接下来，添加以下属性以配置JPA。

spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

有关更多设置和属性，我建议阅读《Spring Boot参考指南》以获取有关属性的信息，请检查此综合列表。

接下来，在中WebApplicationStarter添加HibernateJpaSessionFactoryBean将创建的JPA公开EntityManagerFactory为SessionFactory。

@Configuration
@EnableAutoConfiguration
@ComponentScan("com.mytest")
public class WebApplicationStarter extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(WebApplicationStarter.class);
    }

    public static void main(String[] args) throws Exception {
        ApplicationContext context = SpringApplication.run(WebApplicationStarter.class, args);
    }

    @Bean
    public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
        return hemf.getSessionFactory();
    }
}

然后，只需@Autowire将SessionFactory到您UserServiceImpl。

@Service
@Transactional
public class UserServiceImpl implements UserService {

    @Autowired
    private SessionFactory sessionFactory;

}

现在您可以使用了SessionFactory。
