Hibernate，EJB，javax.persistence.TransactionRequiredException：没有事务正在进行中

时间：2016-02-02 16:45:42

标签： hibernate jpa java-ee ejb

我有一个应用程序在尝试使用容器管理的事务在无状态EJB中的EntityManager上调用flush时抛出异常。异常表明该方法不在事务中，但我无法理解为什么它不会。我已经尝试在EJB方法和类上添加@TransactionAttribute注释，但它似乎没有任何效果。我的消息来源如下。

的persistence.xml 

<?xml version="1.0"?>

<persistence

      <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/>
    </properties>

  </persistence-unit>

EJB-jar.xml中 

<?xml version="1.0" encoding="UTF-8"?>

SimpleTransactionBean.java 

package simple.ejb;

import javax.ejb.Stateless;

import javax.persistence.PersistenceContext;
import javax.persistence.EntityManager;

import simple.entity.SimpleEntity;


@Stateless
public class SimpleTransactionBean implements SimpleTransaction
{
  @PersistenceContext(unitName="simple-unit")
  private EntityManager entityManager;

  public void addTransaction(String transactionNumber)
  {
    SimpleEntity simpleEntity = new SimpleEntity(transactionNumber);
    this.entityManager.persist(simpleEntity);
    this.entityManager.flush();
  }
}

调用EJB的JSF Bean 

package simple.web;

import javax.ejb.EJB;

import simple.ejb.SimpleTransaction;

import simple.entity.SimpleEntity;


public class SimpleEntityAdder
{
  private String transactionNumber;

  public String getTransactionNumber() { return this.transactionNumber; }
  public void setTransactionNumber(String transactionNumber) { this.transactionNumber = transactionNumber; }

  @EJB
  private SimpleTransaction simpleTransaction;

  public void add()
  {
    this.simpleTransaction.addTransaction(this.transactionNumber);
  }
}

当我打开org.hibernate.transaction包的所有日志记录时，我看到在hibernate代码中发生的NullPointerException如下所示：

java.lang.NullPointerException

在做了一些谷歌搜索之后，我修改了我的persistence.xml以更改 hibernate.transaction.factory_class 属性并添加了 hibernate.transaction.jta.platform 属性。这解决了我的问题。另请注意，我已将 hibernate.classloading_use_current_tccl_as_parent 属性添加到另一个不相关的错误修复程序中。我的最终persistence.xml看起来像这样：

<?xml version="1.0"?>

<persistence
  xmlns="http://java.sun.com/xml/ns/persistence"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
  version="2.0"
>
  <persistence-unit name="simple-unit" transaction-type="JTA">

    <description>Simple JPA unit.</description>
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>jdbc/datasource-core</jta-data-source>
    <class>simple.entity.SimpleEntity</class>

    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
      <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.CMTTransactionFactory"/>
      <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>

      <property name="hibernate.classloading.use_current_tccl_as_parent" value="false"/>
    </properties>

  </persistence-unit>

</persistence>

请注意，我的解决方案是在glassfish上运行而不是在weblogic上运行。 weblogic的 hibernate.transaction.jta.platform 属性可能不同。
