spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext
# stripped before adding them to the entity manager
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

 

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()
}
