春季冬眠手动提交

Question

有人可以帮忙吗？

目前我遇到了一些问题，我使用spring，jpa，hibernate。 这里是问题，当我尝试保存多个对象，然后手动回滚，因为当solrj返回false。

我尝试了以下内容：
1的UserTransaction（例外：Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException）

2. entitymanager.gettransaction().begin（例外：共享经理）

感谢，如果你能帮助我弄清楚。

头：

@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; 
    } 
} 

这里是错误日志

Answer 1

正确的方法是删除所有手动事务管理使用@Transactional时。在适当的CMT上下文中，您不应该手动与事务交互，@transactional可确保您的方法在事务内部运行，将事务上下文传播给委托调用，并在抛出异常时在执行结束时提交或回滚。你可以做的唯一的事情是强迫使用setRollbackOnly()回滚上EJBContext

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

否则，如果你更喜欢手动管理事务：

使用您的Spring上下文定义transactionManager的豆你entityManagerFactory的。

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

，并使用这种方式：

@Inject 
JpaTransactionManager txManager; 

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

Answer 2

的问题是，您保存方法注释事务，这意味着，这项交易将被Spring处理，但该方法在你试图管理事务以编程方式使用JPA API。

所以你是错误地混合两种方法。理想情况下，您应该只使用Transactional注释。

下面我已经添加了来自处理此类的Spring帮助程序类的源代码。相关类是org.springframework.orm.jpa.SharedEntityManagerCreator.It拥有一个私人静态类SharedEntityManagerInvocationHandler和相关代码，其中抛出错误低于

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"); 
..... 
..... 
    } 

原来这就是我上面提到的。

您正在调用getTransaction方法，并且出现错误。

因此，摆脱方法内部的事务处理并仅保留Transactional注释。
