Spring Boot - 处理Hibernate SessionFactory [英] Spring Boot - Handle to Hibernate SessionFactory

问题描述

有人知道如何获得由Spring Boot创建的Hibernate SessionFactory的句柄吗？

解决方案

您可以完成此操作与：

$ p $ SessionFactory sessionFactory =

其中entityManagerFactory是JPA EntityManagerFactory 。

  package net.andreaskluth.hibernatesample; 
 
导入javax.persistence.EntityManager; 
 import javax.persistence.EntityManagerFactory; 
 
 import org.hibernate.Session; 
 import org.hibernate.SessionFactory; 
 import org.hibernate.Transaction; 
 import org.springframework.beans.factory.annotation.Autowired; 
 import org.springframework.stereotype.Component; 
 
 @Component 
 public class SomeService {
 
 private SessionFactory hibernateFactory; 
 $ b $ @Autowired 
 public SomeService（EntityManagerFactory factory）{
 if（factory.unwrap（SessionFactory.class）== null）{
 throw new NullPointerException（factory不是休眠工厂）; 
} 
 this.hibernateFactory = factory.unwrap（SessionFactory.class）; 
} 
 
} 
  

Does anyone know how to get a handle the Hibernate SessionFactory that is created by Spring Boot?

解决方案

You can accomplish this with:

SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);

where entityManagerFactory is an JPA EntityManagerFactory.

package net.andreaskluth.hibernatesample;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class SomeService {

  private SessionFactory hibernateFactory;

  @Autowired
  public SomeService(EntityManagerFactory factory) {
    if(factory.unwrap(SessionFactory.class) == null){
      throw new NullPointerException("factory is not a hibernate factory");
    }
    this.hibernateFactory = factory.unwrap(SessionFactory.class);
  }

}
