配置类
package com.ims; import java.util.Properties; import javax.sql.DataSource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.orm.hibernate5.LocalSessionFactoryBean; @Configuration public class HibernateConfig { @Value("${spring.jpa.properties.hibernate.current_session_context_class}") public String current_session_context_class; @Autowired private DataSource dataSource; @Bean public LocalSessionFactoryBean sessionFactoryBean() { LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean(); sessionFactoryBean.setDataSource(dataSource); sessionFactoryBean.setPackagesToScan("com.ims");//dao和entity的公共包 Properties properties = new Properties(); properties.setProperty("hibernate.current_session_context_class", current_session_context_class); sessionFactoryBean.setHibernateProperties(properties); return sessionFactoryBean; } }
使用sessionFactory
@Autowired private EntityManagerFactory sessionFactory; public Session getSession() {
##使用此方式 service层 要使用事务管理
return sessionFactory.unwrap(SessionFactory.class).getCurrentSession();
##使用此方式 service层 不要使用事务管理,但是要手动关闭session
#return sessionFactory.unwrap(SessionFactory.class).openSession()
}
