【问题描述】：

有人可以帮忙吗？

目前我遇到了一些问题，我正在使用 spring、jpa、hibernate。这是问题所在，当我尝试保存几个对象，然后像 solrj 返回 false 时手动回滚。

我尝试了以下方法：
1。用户事务（例外：Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException）

2.entitymanager.gettransaction().begin（例外：共享管理器）

谢谢，如果你能帮我弄清楚。

标题：

@Service("jpaWallPostService")
@Repository
public class WallPostServiceImpl implements WallPostService {
    //........
    @PersistenceContext
    private EntityManager em;

========================================

  @Transactional(readOnly=false)
public boolean save(String solrURL,int userid,wall_post wallPost,List<String> groupsid,List<String> hashtag){


    try{
        em.getTransaction().begin();// ***error occur on here*** and stop here
        //...............proccess
        boolean ok = SolrJ.IndexingWallPost(solrURL,userid, wallPost.getTitle(), wallPost.getMessage(), hashtag,groupsid);
        if(!ok)
            em.getTransaction().rollback();



        em.getTransaction().commit();
        return true;
    }
    catch(Exception e)
    {
        em.getTransaction().rollback();
        return false;
    }
}

这是错误日志

发布完整的错误日志

标签： spring hibernate jpa transactions rollback

【解决方案1】：

正确的方法是在使用@Transactional 时删除所有手动事务管理。在适当的 CMT 上下文中，您不应手动与事务交互，@transactional 确保您的方法将在事务中运行，将传播事务上下文以委托调用，并将在执行结束时提交或在抛出异常的情况下回滚.您唯一可以做的就是在EJBContext 上使用setRollbackOnly() 强制回滚

见：is there a way to force a transactional rollback without encountering an exception?

否则，如果您更喜欢手动管理事务：

使用你的 entityManagerFactory 在你的 spring 上下文中定义一个 transactionManager bean。

 <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
 </bean>

并以这种方式使用它：

@Inject
JpaTransactionManager txManager;

DefaultTransactionDefinition def = new DefaultTransactionDefinition();
def.setName("rootTransaction");
def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
TransactionStatus status = txManager.getTransaction(def);
[...]
txManager.commit(status);

【讨论】：

我原来确实设置了transactionmanager....甚至没有启动，然后出错。所以其余代码在错误提示后不会运行
您如何管理注释处理？难道你没有这样的东西：
然后呢？如果您在 bean 中注入 transactionManager 并在其上调用 .commit() 会发生什么问题？
原帖上的错误---（不允许在共享的EntityManager上创建事务-改用Spring事务或EJB CMT）
First---Gab，你很有帮助，谢谢 :) 刚才我尝试抛出 RuntimeException，它起作用了，它回滚了记录。以前不起作用，这是因为我确实尝试捕获异常已经消耗的异常。然而，虽然它可以工作（通过抛出异常），但我认为这不是一个好主意和正确的方法。我现在就试试你的方法:)

【解决方案2】：

问题是您的保存方法被注释为 Transactional，这意味着事务将由 Spring 处理，但在该方法中，您尝试使用 JPA API 以编程方式管理事务。

所以你错误地混合了两种方法。理想情况下，您应该只使用 Transactional 注释。

下面我添加了处理此问题的 Spring 辅助类的源代码。相关类是org.springframework.orm.jpa.SharedEntityManagerCreator。它有一个私有静态类SharedEntityManagerInvocationHandler，抛出错误的相关代码如下

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
  .....
  .....
  else if (method.getName().equals("getTransaction")) {
      throw new IllegalStateException("Not allowed to create transaction on shared"
                             +" EntityManager - use Spring transactions or EJB CMT instead");
.....
.....
  }

这就是我上面提到的。

您正在调用 getTransaction 方法并收到错误消息。

所以摆脱方法内部的事务处理，只坚持 Transactional 注释。

【讨论】：

是的，你的方法体应该像这样boolean ok = SolrJ.IndexingWallPost(solrURL,userid, wallPost.getTitle(), wallPost.getMessage(), hashtag,groupsid); if(!ok) // throw some RuntimeException;
根据我的研究和理解，我同意您的观点。我猜春天正在占据交易，我试图得到并控制它。但是我只是删除了@Transactional 并尝试获取事务，然后我遇到了这个问题（“java.lang.IllegalStateException：不允许在共享 EntityManager 上创建事务 - 改用 Spring 事务或 EJB CMT”）
orid---你的方法是可行的，但只是为了确保不要在这个区域内尝试和捕捉，否则我会遇到同样的问题。谢谢！
