春天@Transactional沒有創造所需的事務

好了，我終於屈服於同行的壓力，並開始在我的web應用程序中使用Spring： - ）...春天@Transactional沒有創造所需的事務

所以我試圖讓事務處理的東西工作，我似乎無法得到它。

我的Spring配置如下：


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

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:p="http://www.springframework.org/schema/p" 
     xmlns:tx="http://www.springframework.org/schema/tx" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
          http://www.springframework.org/schema/beans/spring-beans.xsd 
          http://www.springframework.org/schema/tx 
          http://www.springframework.org/schema/tx/spring-tx.xsd"> 

    <bean id="groupDao" class="mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao" lazy-init="true"> 
     <property name="entityManagerFactory" ><ref bean="entityManagerFactory"/></property> 
    </bean> 

<!-- enables interpretation of the @Required annotation to ensure that dependency injection actually occures --> 
    <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/> 

    <!-- enables interpretation of the @PersistenceUnit/@PersistenceContext annotations providing convenient 
     access to EntityManagerFactory/EntityManager --> 
    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/> 

    <!-- uses the persistence unit defined in the META-INF/persistence.xml JPA configuration file --> 
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> 
     <property name="persistenceUnitName" value="CONOPS_PU" /> 
    </bean> 

    <!-- transaction manager for use with a single JPA EntityManagerFactory for transactional data access 
     to a single datasource --> 
    <bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
     <property name="entityManagerFactory" ref="entityManagerFactory"/> 
    </bean> 

    <!-- enables interpretation of the @Transactional annotation for declerative transaction managment 
     using the specified JpaTransactionManager --> 
    <tx:annotation-driven transaction-manager="jpaTransactionManager" proxy-target-class="true"/> 

</beans>

的persistence.xml：


<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="1.0" 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_1_0.xsd"> 

    <persistence-unit name="CONOPS_PU" transaction-type="RESOURCE_LOCAL"> 

    <provider>org.hibernate.ejb.HibernatePersistence</provider> 

    ... Class mappings removed for brevity... 

    <properties> 

     <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/> 

     <property name="hibernate.connection.autocommit" value="false"/> 
     <property name="hibernate.connection.username" value="****"/> 
     <property name="hibernate.connection.password" value="*****"/> 

     <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/> 
     <property name="hibernate.connection.url" value="jdbc:oracle:thin:@*****:1521:*****"/> 
     <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/> 
     <property name="hibernate.hbm2ddl.auto" value="create"/> 
     <property name="hibernate.show_sql" value="true"/> 
     <property name="hibernate.format_sql" value="true"/> 

    </properties> 

    </persistence-unit> 

</persistence>

的DAO方法來保存我的域對象是這樣的：


    @Transactional(propagation=Propagation.REQUIRES_NEW) 
    protected final T saveOrUpdate (T model) 
    { 
     EntityManager em = emf.createEntityManager (); 
     EntityTransaction trans = em.getTransaction (); 

     System.err.println ("Transaction isActive() == " + trans.isActive ()); 

     if (em != null) 
     { 
      try 
      { 
       if (model.getId () != null) 
       { 
        em.persist (model); 
        em.flush(); 
       } 
       else 
       { 
        em.merge (model); 
        em.flush(); 
       } 
      } 
      finally 
      { 
       em.close(); 
      } 
     } 

     return (model); 
    }

所以我嘗試在我的測試用例中使用以下代碼保存我的Group對象的副本：


    context = new ClassPathXmlApplicationContext(configs); 
    dao = (GroupDao)context.getBean("groupDao"); 

    dao.saveOrUpdate (new Group());

這種炸彈有以下異常：

此外，我得到以下警告首次啓動春季時。由於這些引用的entityManagerFactory和transactionManager的，他們可能對問題的一些影響，但是我一直沒有能夠破譯他們足夠的知道：

沒有人有任何想法，我缺少的是什麼？我完全難倒...

從EntityManagerFactory.createEntityManager()獲取的實體管理器實例不參與Spring管理的事務。

的常用方法獲得實體管理器是使用@PersistenceContext -annotated屬性注入它：

@PersistenceContext 
public void setEntityManager(EntityManager em) { ... }

我將@PersistenceContext添加到了我的DAO類。當我運行它時，我得到： java.lang.IllegalStateException：不允許在共享EntityManager上創建事務 - 使用Spring事務或EJB CMT代替org.springframework.orm.jpa.SharedEntityManagerCreator $ SharedEntityManagerInvocationHandler.invoke（SharedEntityManagerCreator.java:155 ）at mil.navy.ndms.conops.common.dao.impl.jpa.GenericJPADao.saveOrUpdate（GenericJPADao.java:634）at mil.navy.ndms.conops.common.dao $ Proxy27.getTransaction（Unknown Source）。 impl.jpa.GroupDao.save（GroupDao.java:645） – Steve 2010-03-11 18:00:58

@Steve：你不應該在這個'EntityManager'上調用'getTransaction' – axtavt 2010-03-11 18:07:55

就是這樣。我認爲我至少可以檢查當前事務以確定@Transactional註釋是否正在創建事務。這僅僅是爲了調試的目的，所以當我刪除它，我得到了我的交易。謝謝... – Steve 2010-03-11 18:14:52

的問題可能是由你們共同造成的註釋受保護的方法，以及使用proxy-target-class="true"。這是一個糟糕的組合。 Spring生成的事務代理只能使用公共註釋方法正常工作，但如果它們不是，則不會投訴。

嘗試使saveOrUpdate()方法公開，或者更好的是爲您的DAO定義一個接口，並刪除proxy-target-class="true"設置。這是最安全，最可預測的技術。

該方法也是「final」。它也防止使用'proxy-target-class =「true」'。 – axtavt 2010-03-11 17:35:37

使方法公開失敗的方式相同。 – Steve 2010-03-11 17:37:06

刪除最終也沒有效果。 – Steve 2010-03-11 17:38:25

在我的情況：

使用JPA與Spring MVC - 我所有的測試和代碼運行罰款沒有錯誤 - 症狀是提交不會保存到數據庫，無論我嘗試了什麼。

我必須在我的情況下加我的applicationContext.xml和CGLIB的節點p-2.1_3.jar aopalliance-1.0.jar

絕對的修補程序。如果沒有註釋驅動，Spring將不會掃描@Transactional註釋

除了那些依賴項，你的applicationContext.xml如何結束呢？ – Marcelo 2013-07-15 01:07:37
