spring-boot 1.1.8，遇到异常No CurrentSessionContext configured开头，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类配置此属性？
更新：我更改为 Hibernate4.x Way 来定义SessionFactory但仍然遇到同样的错误，请帮忙！
使用java 1.8和speing boot 1.1.8
这是我的pom.xml

答案 0 :(得分：23)
您对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难以使用这些框架并尝试解决它们。我强烈建议使用Spring Boot，让它为你配置一些东西。
首先删除你的HibernateUtils，深埋它，再也不要再看它了。您也可以删除AppConfig作为Spring Boot，并将负责DataSource。
接下来在application.properties目录中创建一个名为src/main/resources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=
这会自动为您配置DataSource。您不需要驱动程序，因为它是从您提供的URL中推断出来的。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
对于更多设置和属性，我建议您阅读Spring Boot Reference Guide属性，然后查看comprehensive list。
接下来在WebApplicationStarter添加HibernateJpaSessionFactoryBean，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@Autowire SessionFactory进入UserServiceImpl。
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private SessionFactory sessionFactory;
}
现在您可以使用SessionFactory。
答案 1 :(得分：-1)
我收到此错误是因为我有
sessionFactory.getCurrentSession();
当我将其更改为
sessionFactory.openSession();
工作正常。
