Spring 내에서 트랜잭션이 시작되지 않음 @ Transaction_transactional 메서드

Question

Spring (3.0.5), Hibernate (3.6.0) 및 Wicket (1.4.14)를 사용하여 응용 프로그램을 개발하는 동안 이상한 문제가 발생했습니다. 문제는 : 내가 데이터베이스에 개체를 저장하거나 수정할 수 없다는 것입니다. EntityManager.persist (foo)에 대한 객체 또는 호출의 모든 변경 사항이 단순히 무시된다는 것을 의미하지는 않습니다. 작업을 선택합니다. 여기

public class ComicDetailsPage extends PublicBasePage { 

@Override 
protected void onConfigure() { 
    System.out.println("In onConfigure"); 
    super.onConfigure(); 
    comicDAO.insert("abc"); 

} 

@SpringBean(name="comicDAO") 
private ComicDAO comicDAO; 

    (....) 

내가 로깅을 설정 comicDAO

@Service 
public class ComicDAO { 

@PersistenceContext 
private EntityManager em; 

(...) 

@Transactional 
public void insert(String title) { 
    Comic c = new Comic(); 
    c.setTitle(title); 
    em.persist(c); 
} 

@Transactional 
public Comic add1toTitle(int pk) { 
    System.out.println("Beginning fetching"); 
    Comic c = em.find(Comic.class, pk); 
    System.out.println("Fetched updating"); 
    c.setTitle(c.getTitle()+"1"); 
    System.out.println("Updated persisting"); 
    em.persist(c); 
    System.out.println("Persisted returning"); 
    return c; 
} 

이며, 여기의 관련 부분은 다음과 같은, 내가 데이터베이스에 객체를 저장하려고 일부 개찰구 페이지에 -

샘플의 경우는 간단하다 로그 (Hibernate와 Spring 모두 TRACE로 설정 됨). 나는 ** 중요한 라인이라고 생각하는 라인에 **를 추가했다.

물론 개체가 데이터베이스에 저장되지 않습니다.

마지막 파일 - 내 applicationCOntext.xml 나는이 문제와 그 해결 방법이 될 수 있는지 아무 생각

. 내 코드에서 트랜잭션을 관리하고 싶지 않습니다. 이것이 Spring의 목적입니다.

Answer 1

a) 귀하가 정의하는 모두 최대 절전 모드 SessionFactory와 JPA EntitymanagerFactory. 어느 쪽이 될 것인가? Hibernate의 Session API 또는 JPA의 Entitymanager API를 Hibernate와 함께 제공 업체로 사용하십시오. 둘 다 사용할 수는 없습니다.

b) 귀하가 HibernateTransactionManager를 정의하지만, 당신은 당신의 코드에서 EntityManager를 사용하고 있기 때문에, 당신은 JpaTransactionManager 대신 필요

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

이 applicationContext.xml의 주석 버전입니다 :

를

<?xml version="1.0" encoding="UTF-8"?> 
<beans (...)> 

    <context:component-scan base-package="pl.m4ks.comics"/> 
    <context:annotation-config /> 

    <bean id="dataSource" 
    class="org.springframework.jdbc.datasource.SimpleDriverDataSource"> 
     <property name="driverClass" value="com.mysql.jdbc.Driver"/> 
     <property name="url" value="jdbc:mysql://localhost:8889/comics" /> 
     <property name="username" value="root"/> 
     <property name="password" value="root" />   
    </bean> 

    <!-- use either this: --> 
    <bean id="entityManagerFactory" 
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <property name="persistenceUnitName" value="main" /> 
     <property name="dataSource" ref="dataSource" /> 
    </bean> 

    <!-- or this --> 
    <bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
     <property name="dataSource"> 
      <ref bean="dataSource"/> 
     </property> 
     <property name="packagesToScan"> 
      <value>pl.m4ks.comics</value> 
     </property> 
    </bean> 
    <!-- (but not both) --> 

    <!-- this is correct for AnnotationSessionFactoryBean, but not if you use 
     LocalContainerEntityManagerFactoryBean --> 
    <bean id="txManager" 
    class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
     <property name="sessionFactory"> 
      <ref bean="sessionFactory" /> 
     </property> 
    </bean> 

    <!-- not necessary, <context:annotation-config /> automatically includes this -->

    <tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>

디자인 노트 : DAO는 트랜잭션이 아니어야합니다.. 트랜잭션을 관리하는 서비스 계층을 사용해야합니다. 참조 용으로 this question (및 기타 다수 참조)을 참조하십시오.

Answer 2

당신은 실제 데이터베이스에 저장하려면 flush()

EntityManager의

에 다음과 같은 메소드를 호출 할 필요가

Answer 3

최대 절전 모드 설정에서 hibernate.connection.autocommit = true로 설정해 보셨습니까? 그것은 문제를 해결할 것입니다. 그러나 접근 방법이 얼마나 효율적인지 알아 내야합니다.
