No CurrentSessionContext configured
提问by Teifi
sorry for bad English. I get my project started with spring-boot 1.1.8, Encountered Exception No CurrentSessionContext configured, then I did some search， add property <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>could solve this problem, but
抱歉英语不好。我开始我的项目spring-boot 1.1.8，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
how to config this property using java class?
如何使用 java 类配置此属性？
update: I changed to the Hibernate4.x Wayto define SessionFactory but still got the same error, please help!
更新：我改成Hibernate4.x方式来定义SessionFactory但是还是出现同样的错误，请大家帮忙！

Your configuration and usage of hibernate is wrong. You are using Spring and even better Spring Boot, however what you posted tries very hard not to use those frameworks and tries to work around them. I strongly suggest using Spring Boot and let that configure the things for you.
你对hibernate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。
First delete your HibernateUtils, burry it deep and never look at it again. You can also delete your AppConfigas Spring Boot can and will take care of the DataSource.
先删掉你的HibernateUtils，把它埋得更深，再也不看。您也可以AppConfig像 Spring Boot 一样删除您的DataSource.
Next create a file called application.propertiesin your src/main/resourcesdirectory and put the following content in there.
接下来application.properties在您的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=
This will automatically configure a DataSourcefor you. You don't need the driver as that is deduced from the url you provide. Next add the following properties to configure JPA.
这将自动DataSource为您配置一个。您不需要驱动程序，因为这是从您提供的 url 推断出来的。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
For more settings and properties I suggest a read of the Spring Boot Reference Guidefor the properties check this comprehensive list.
有关更多设置和属性，我建议阅读Spring Boot 参考指南以了解属性，请查看此综合列表。
Next in your WebApplicationStarteradd the HibernateJpaSessionFactoryBeanto expose the created JPA EntityManagerFactoryas a SessionFactory.
接下来在您的WebApplicationStarter添加中将HibernateJpaSessionFactoryBean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();
}
}
Then just @Autowirethe SessionFactoryinto your UserServiceImpl.
然后，只需@Autowire将SessionFactory到您UserServiceImpl。
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private SessionFactory sessionFactory;
}
Now you can just use the SessionFactory.
现在你可以只使用SessionFactory.
回答by parsecer
I got this error because I had
我收到这个错误是因为我有
sessionFactory.getCurrentSession();
when I changed it to
当我把它改成
sessionFactory.openSession();
it worked fine.
它工作正常。
