java - 从 EntityManagerFactory 发出连接 EntityManager-6ren

java - 从 EntityManagerFactory 发出连接 EntityManager

转载作者：搜寻专家更新时间：2023-11-01 03:29:27

我知道 spring 有它自己的 JPA 对象工厂，但我只想让它按原样工作......从那里我将研究最佳实践。我只是在理解过程中。

这是我尝试生成 bean 的实际代码:

    EntityManagerFactory emf = Persistence.createEntityManagerFactory("test");
    EntityManager em = emf.createEntityManager();

我必须让它工作(但不工作)(编辑:注意 myFactoryBean 编译没有问题 emf 是罪魁祸首):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="autodetect">
  <bean id="emf" class="javax.persistence.Persistence" factory-method="createEntityManagerFactory">
    <constructor-arg value="test" />
  </bean>
  <bean id="em" factory-bean="emf" factory-method="createEntityManager"/>
</beans>

这是堆栈跟踪:
