为什么我坚持了却什么也没有发生？

我希望我不会问你已经回答过的问题，但我无法理解我的问题...我解释一下：

我使用 Spring 和 Hibernate，我有一个 Manager 接口，以及一个实现我的接口的 Manager。管理器是这样的：

@Service
@Transactional
public class ManagerImpl implements Manager {
    @PersistenceContext(type = PersistenceContextType.TRANSACTION, unitName="Service")
    private EntityManager em;

    public void storeHistoricMessage(...params...) throws DBException{
        HistoricMessage historicMessage = new HistoricMessage(); 
        // ... initialization of historicMessage
        try {
            em.persist(historicMessage);
        }
        catch (Exception e){
            // process the exception if exists... 
        }
    }
}

我这样调用我的服务：

@Service
public class OtherManager {
    @Autowired
    private Manager manager;

    public void storeHistoricMessage(...params...) {
        manager.storeHistoricMessage(...params...);
    }
}

我的应用程序上下文是这样定义的：

        </property>
    </bean>

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

最后，我的 persistence.xml 是这样的：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    version="1.0">

    <persistence-unit name="Service" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>package.HistoricMessage</class>

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
            <property name="hibernate.archive.autodetection" value="class, hbm" />
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.format_sql" value="false" />
            <property name="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl.auto}" />
        </properties>
    </persistence-unit> 
</persistence>

问题是当我坚持时，什么也没有发生：没有插入数据库，没有错误消息，也不例外…… 我做了很多测试，也许有一些帮助：

  • 如果我尝试用 em.find() 取回我的对象​​，我明白了......缓存优化？
  • 如果我捕获它，并在启动服务后重命名数据库中的表，我没有错误，他总是很高兴...
  • 如果我尝试 em.flush()，它会抛出异常，因为没有事务正在进行...

最后，这是我可以看到的跟踪日志：

非常感谢您的帮助！

编辑 ： 非常抱歉，我明白发生了什么，但你无法找到，因为我确实简化了我的项目的架构，但我没有告诉你原因： 在这个项目中，我有几个应用程序上下文文件和几个数据源，因此我使用了多次......而使用 Spring 2.5，你只能拥有一个！ 这样我就无法在第二个服务中使用事务...... 为了解决这个问题，我使用了这样的aop：

<tx:advice id="txAdviceSelfCare" transaction-manager="transactionManager_service">
    <!-- the transactional semantics... -->
    <tx:attributes>
        <!-- other methods use the default transaction settings (see below) -->
        <tx:method name="*" />
    </tx:attributes>
</tx:advice>

<aop:config>
    <aop:pointcut id="ServiceManagerOperations"
        expression="execution(* package.ServiceManager.*(..))" />
    <aop:advisor advice-ref="txAdviceService"
        pointcut-ref="ServiceManagerOperations" />
</aop:config>

<!-- a PlatformTransactionManager is still required -->
<bean id="transactionManager_service" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory_service" />
</bean>

感谢大家的帮助！

I hope I does not ask a question you already answered, but I am not able to understand my problem... I explain :

I work with Spring and Hibernate, I have a Manager interface, and a Manager that implements my interface. Manager is like this :

@Service
@Transactional
public class ManagerImpl implements Manager {
    @PersistenceContext(type = PersistenceContextType.TRANSACTION, unitName="Service")
    private EntityManager em;

    public void storeHistoricMessage(...params...) throws DBException{
        HistoricMessage historicMessage = new HistoricMessage(); 
        // ... initialization of historicMessage
        try {
            em.persist(historicMessage);
        }
        catch (Exception e){
            // process the exception if exists... 
        }
    }
}

I call my service like this :

@Service
public class OtherManager {
    @Autowired
    private Manager manager;

    public void storeHistoricMessage(...params...) {
        manager.storeHistoricMessage(...params...);
    }
}

My application context is defined like this :

        </property>
    </bean>

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

And Finally, my persistence.xml is like this :

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

    <persistence-unit name="Service" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>package.HistoricMessage</class>

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
            <property name="hibernate.archive.autodetection" value="class, hbm" />
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.format_sql" value="false" />
            <property name="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl.auto}" />
        </properties>
    </persistence-unit> 
</persistence>

The problem is that when I persist, nothing happens : no insert in database, no error message, no exception....
I made a lot of tests, and I have perhaps some helps :

  • If I try to get back my object with em.find(), I get it... cache optimization ?
  • If I trap it, and rename table in database after start service, I have no error, he is always happy...
  • If I try em.flush(), it throws a Exception because no transaction is in progress...

Finally, here are TRACE logs I can see :

Thanks a lot for you help !

Edit :
I'm very sorry, I understood what happend and you wasn't able to find because I really simplified architecture of my project and I didn't tell you about the reason :
In this project, I have several application-context files, and several datasources, so that I use several times.... And with Spring 2.5, you can have only one !
So that I can't use transactions in my second service...
To solve that, I used aop like this :

<tx:advice id="txAdviceSelfCare" transaction-manager="transactionManager_service">
    <!-- the transactional semantics... -->
    <tx:attributes>
        <!-- other methods use the default transaction settings (see below) -->
        <tx:method name="*" />
    </tx:attributes>
</tx:advice>

<aop:config>
    <aop:pointcut id="ServiceManagerOperations"
        expression="execution(* package.ServiceManager.*(..))" />
    <aop:advisor advice-ref="txAdviceService"
        pointcut-ref="ServiceManagerOperations" />
</aop:config>

<!-- a PlatformTransactionManager is still required -->
<bean id="transactionManager_service" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory_service" />
</bean>

Thanks all for your help !

您可以尝试检查数据库上到底发生了什么吗？
尝试激活该数据库上的日志设施，如果您安装了这样的工具来嗅探 Java 代码和数据库服务器之间的网络流量...它可能很有用...
你可以要求你的 JPA 层显示生成的 SQL，它可以给你有趣的数据......

could you try to inspect what really happens on your database ?
Try to activate log facilities on that database and if you have such tool installed to sniff network traffic between your Java code and the database server ... it could be useful...
You could ask your JPA layer to show SQL generated , it could give you interesting data...

更改您的 catch 块以执行某些操作并观察它打印的内容。

    try {
        em.persist(historicMessage);
    }
    catch (Exception e){
        e.printStackTrace(); // use a logger if available
    }

您还可以将以下属性更改为 true 以查看发生了什么。

<property name="hibernate.show_sql" value="true" />

另外，养成使用合适的日志框架（例如 SLF4J）跟踪方法入口/出口的习惯。

Change your catch block to do something and watch what it prints.

    try {
        em.persist(historicMessage);
    }
    catch (Exception e){
        e.printStackTrace(); // use a logger if available
    }

You can also change the below property to true to see what's going on.

<property name="hibernate.show_sql" value="true" />

Also, make it a habit to trace method entry/exits using a suitable logging framework such as SLF4J.

请注意，实际插入不会发生在 em.persist 语句中，因为调用是事务性的，因此您的 try/catch 根本不会做太多事情。实际的持久化是在事务结束时完成的，即服务层调用完成时（从方法返回后）。在调试持久性时，这些知识至关重要。

Note that the actual insert does not happen in the em.persist statement since the call is transactual, so your try/catch will not do much at all. The actual persist is done when the transaction ends, which is when the service layer call is finished (after return from your method). This knowledge is critical when debugging persistence.

验证您正在查找详细信息的数据库。日志清楚地表明提交已完成..

将方法调用放在 try catch 中

public void storeHistoricMessage(...params...) {
    try {
       manager.storeHistoricMessage(...params...);
    } catch (Exception e) {
       e.printStackTrace(); // use a logger if available
    }
}

数据应在 manager.storeHistoricMessage 方法调用（通过事务管理代理）结束时持久保存，而不是在 em.persist 调用时保存。您也可以尝试 em.flush：

try {
        em.persist(historicMessage);
        em.flush(); //force DB insert
    }...

看起来您没有看到某个地方抛出的异常，可能是由事务管理器抛出的。

Place your method call in try catch

public void storeHistoricMessage(...params...) {
    try {
       manager.storeHistoricMessage(...params...);
    } catch (Exception e) {
       e.printStackTrace(); // use a logger if available
    }
}

Data should be persisted at the end of manager.storeHistoricMessage method call (by transaction management proxy) not at em.persist call. You could also try em.flush:

try {
        em.persist(historicMessage);
        em.flush(); //force DB insert
    }...

It looks like you don't see an exception wich is thrown somwhere, problably by transacion manager.
