为什么 @Transactional 对于 EAP 7.2.x 和 7.3.x 的应用程序管理的 EntityManager 会失败，而 7.1.x 可以完美运行？
Why does @Transactional fail for an application-managed EntityManager with EAP 7.2.x and 7.3.x while 7.1.x works flawless?
下面的简单示例在 JBoss EAP 7.1.6（及之前）中可以正常工作，但在 EAP 7 中失败。2.x和最新的7.3.0.
我创建了一个简单的可重现示例并将其推送到 https://github.com/da3x/JBoss-EAP-EntityManager-Problem。我也在联系 Red Hat 支持...但有人可能已经解决了这个问题。
#save1() 和 #save2() 这两种方法用不同的 EntityManager 做同样的事情。
第一个是 application-managed，第二个是 container-managed.
使用 EAP 7.1.x 两者都正确加入事务...使用 EAP 7.2.x 和 7.3.x application-managed 刷新失败。
package eu.ecg.test;
import java.io.Serializable;
import javax.inject.Inject;
import javax.inject.Named;
import javax.persistence.EntityManager;
import javax.transaction.Transactional;
@Named
public class MyBean implements Serializable {
private static final long serialVersionUID = 1L;
private static final String VIEW_ID = "/Transactional.xhtml?faces-redirect=true";
@Inject
@ApplicationManaged
private EntityManager em1;
@Inject
@ContainerManaged
private EntityManager em2;
@Transactional
public String save1() {
System.out.println("MyBean.save1()");
this.em1.flush(); // NOTE: needs Transaction!
System.out.println("OK!");
return VIEW_ID;
}
@Transactional
public String save2() {
System.out.println("MyBean.save2()");
this.em2.flush(); // NOTE: needs Transaction!
System.out.println("OK!");
return VIEW_ID;
}
}
两个EntityManager都是由以下class产生的：
package eu.ecg.test;
import java.io.Serializable;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;
import javax.persistence.PersistenceUnit;
@ApplicationScoped
public class Persistence implements Serializable {
private static final long serialVersionUID = 1L;
@PersistenceUnit(unitName = "example")
private EntityManagerFactory factory;
@PersistenceContext(unitName = "example")
private EntityManager em;
/**
* @see PersistenceContextType#EXTENDED
*/
@Produces
@ApplicationManaged
public EntityManager applicationManaged() {
System.out.println("Persistence.applicationManaged()");
return this.factory.createEntityManager();
}
/**
* @see PersistenceContextType#TRANSACTION
*/
@Produces
@ContainerManaged
public EntityManager containerManaged() {
System.out.println("Persistence.containerManaged()");
return this.em;
}
}
这个精简的示例演示了我现在遇到的核心问题。真正的应用程序要复杂得多，有超过 30 万行代码——但它表现出相同的行为。虽然它可以在 EAP 7.0.x 和 7.1.x 上正常工作，但在 7.2.x 和 7.3.0.
上会失败
我也知道我可以通过将 em.joinTransaction() 添加到 #save1() 来解决这个问题 – 但据我所知这不是必需的。 @Transactional 注释应该在这里发挥作用……不是吗？
我们正在使用应用程序管理的 EntityManager，因为有效的 PersistenceContextType#EXTENDED 允许我们通过在事务上下文之外使用托管实体来延迟加载——同时仅读取数据。
