未配置 CurrentSessionContext

【问题标题】：No CurrentSessionContext configured未配置 CurrentSessionContext
【发布时间】：2014-12-27 08:59:09
【问题描述】：

抱歉英语不好。我的项目从spring-boot 1.1.8开始，遇到异常No CurrentSessionContext configured，然后我做了一些搜索，添加属性<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>可以解决这个问题，但是

如何使用 java 类来配置这个属性？

更新：我改成Hibernate4.x方式来定义SessionFactory但还是报同样的错误，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>

这是我的服务和控制器

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")

            HttpServletResponse response) {
        String usrEmail = request.getParameter("email");
        boolean exist = userService.isEmailExist(session, usrEmail);
        //todo
    }
}

WebApplicatoinStarter.java

@Configuration

【问题讨论】：

  • 不，这并不能解决问题，只会让问题变得更糟。如果您需要SessionFactory（不知道为什么，但唉）使用HibernateJpaSessionFactoryBean 在您的上下文中获取一个，然后只需注入它而不是打开自己。发布您的配置/应用程序类。我也希望你的UserServiceImpl 被@Service 和@Transactional 注释，因为现在没有交易。
  • @M.Deinum 谢谢先生，谢谢您的期待！是的，我确实打算使用SessionFactory，因为我决定使用休眠标准。
  • JPA 也有条件（从 JPA2 开始），您应该小心使用这些条件，对于简单查询，只需使用查询即可。
  • @M.Deinum 先生我更新了我的问题，你能帮帮我吗？
  • 不要构建自己的数据源。 Spring Boot 就是这样做的。只需将属性添加到您的application.properties。也不要使用 util 类使用 Spring。您正在努力不使用 Spring、Spring Boot 等。您正在尽一切努力解决它。

标签： java spring-boot sessionfactory


【解决方案1】：

你对h​​ibernate的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它们。我强烈建议使用 Spring Boot 并让它为您配置。

先删除你的HibernateUtils，把它埋得很深，再也不看它了。您还可以删除您的 AppConfig，因为 Spring Boot 可以并且会处理 DataSource。

接下来在您的src/main/resources 目录中创建一个名为application.properties 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=

这将自动为您配置一个DataSource。您不需要驱动程序，因为它是从您提供的 url 推导出来的。接下来添加以下属性来配置 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 Reference Guide 的属性，请查看comprehensive list。

接下来在您的WebApplicationStarter 中添加HibernateJpaSessionFactoryBean 以将创建的JPA EntityManagerFactory 公开为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();
    }
}

然后只需将@Autowire 将SessionFactory 放入您的UserServiceImpl。

@Service
@Transactional
public class UserServiceImpl implements UserService {

    @Autowired
    private SessionFactory sessionFactory;

}

现在您可以使用SessionFactory。

【讨论】：

  • 嗯，有趣的是，由于某种原因，正在创建一个未实现所需接口的代理。你有更多的自定义配置而不是依赖 Spring Boot 吗？啊，恐怕你在这里遇到了一个小问题......虽然 Spring 通常已经更新为与 hibernate 4.3 及更低版本一起使用，但我猜这个类是一个疏忽。我更新了应该可行的解决方案的答案。
  • 绝对没有更多的自定义配置。我很沮丧，一旦我使用@Bean HibernateJpaSessionFactoryBean 这个错误出来了，我想把我的头发刮掉！我想配置另一个数据源，一个是读取，另一个是写入，但还没有开始。
  • 我为此创建了一个issue。同时修改答案应该可以。
  • 谢谢先生，您一定是个好父亲！我应该使用较旧的春季版本重新启动我的项目吗？
  • 不，正如我所说的我的答案中的代码（我修改它）应该可以工作，它不再使用HibernateJpaSessionFactoryBean。该问题将在 Spring 的下一个修复程序（4.1.2 和 4.0.8）中得到解决。
【解决方案2】：

我收到此错误是因为我有

sessionFactory.getCurrentSession();

当我把它改成

sessionFactory.openSession();

效果很好。

【讨论】：

  • 是的，这对我也有用，你能给我一些解释吗？
  • @AkhileshMagdum 我希望我能！春天一如既往的混乱
