春天 + Eclipselink + JtaTransactionManager = javax.persistence.TransactionRequiredException

Question

我真的希望你能帮助我。我一直在互联网上寻找答案，但没有一个有效。

我使用 Spring 3 + JTA + EclipseLink，但在刷新事务时遇到 TransactionRequiredException。现在我非常习惯于定义持久性上下文并注入 EntityManager，事务由应用程序服务器处理。

这就是我所得到的。

所以这就是交易，当我取消注释 transactionManager 部分时，程序按预期运行，即我可以看到插入语句。但是，当使用上面的代码时，我得到以下堆栈跟踪：

正如您所看到的，它正确连接到数据库，并且“保留”数据，但从未实际执行插入语句。然后当刷新 EM 时，它会抛出异常。

我们将非常感谢您的帮助。

此致。

Answer 1

好的，所以我想出了如何让它 100% 工作。

首先，我不必在 web.xml 中定义任何持久性（上下文/单元）。接下来，我删除了 transactionmanager 和entityManagerFactory bean。还删除了 context:driven 行。
我还制作了我的“bean”无状态会话 bean。然后我通过 spring 通过 jndi 上下文查找来实例化它。这完全按照我想要的方式自动装配实体管理器。不再担心交易，应用程序服务器会处理它。

所以我的最终配置是：

spring-config.xml ：

<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/CategoryController" id="categoryController"/>
<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/UserController" id="userController"/>

<bean id="applicationContextProvider" class="com.cartouchan.locator.beans.CustomApplicationContext"></bean>

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

bean 示例：

import java.text.MessageFormat;
import java.util.List;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.apache.log4j.Logger;

@Stateless
public class CategoryController {
    private static final Logger logger = Logger.getLogger(CategoryController.class);

    @PersistenceContext
    private EntityManager       entityManager;

    public CategoryController() {
        // TODO Auto-generated constructor stub
    }

    public boolean createCategory(final String name) {
        boolean result = false;
        try {
            com.cartouchan.locator.database.models.Category category = new com.cartouchan.locator.database.models.Category();
            category.setName(name);
            entityManager.persist(category);
            entityManager.flush();
            result = true;
        } catch (Exception ex) {
            logger.error(MessageFormat.format("Could not create the category {0}", name), ex);
        }

        return result;
    }

    public boolean updateCategory(final int id, final String name) {
        boolean result = false;
        try {
            com.cartouchan.locator.database.models.Category category = getCategory(id);
            category.setName(name);
            entityManager.merge(category);
            entityManager.flush();
            result = true;
        } catch (Exception ex) {
            logger.error(MessageFormat.format("Could not update for the category {0} -{1}", id, name), ex);
        }

    return result;
    }

    public boolean deleteCategory(final int id) {
        boolean result = false;
        try {
            com.cartouchan.locator.database.models.Category category = getCategory(id);
            entityManager.remove(entityManager.merge(category));
            entityManager.flush();
            result = true;
        } catch (Exception ex) {
            logger.error(MessageFormat.format("Could not delete for the category {0}", id), ex);
        }

        return result;
    }

    public com.cartouchan.locator.database.models.Category getCategory(final int id) {
        return (com.cartouchan.locator.database.models.Category) entityManager.createQuery("select p from Category p where p.id=:id").setParameter("id", id).getSingleResult();
    }

    public List<com.cartouchan.locator.database.models.Category> getAllCategories() {
        return (List<com.cartouchan.locator.database.models.Category>) entityManager.createQuery("select p from Category p").getResultList();
    }
}

然后要使用该 bean，只需对该 bean 进行标准的 spring 查找即可。简单如馅饼。

Answer 2

为了使用应用程序服务器管理的 JTA 事务，您需要使用应用程序服务器本身创建的 EntityManagerFactroy。

即，您需要删除 LocalContainerEntityManagerFactoryBean 声明并通过 从应用程序服务器获取 EntityManagerFactory。此外，您还应该配置应用程序服务器来创建 EntityManagerFactory - 请参阅应用程序服务器文档。

另请参阅：

• 13.5.1.2 从 JNDI 获取 EntityManagerFactory

Answer 3

property name="eclipselink.target-server" value="WebSphere_7"

设置服务器类型....

希望这个可以工作..
