おはようございます、

Hibernate 3 から 4 にアップグレードしたときに、「悪名高い」現在のセッション エラーが発生しました。それを検索したところ、すべてが適切にセットアップされているようです。私はいくつかの洞察が必要です:)

これが私のconfです：Spring 3.2 Hibernate 4.1.9

事業内容 :

<?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:context="http://www.springframework.org/schema/context"

    </bean>     
</beans>

私のサービス層:

package com.services.user;

@Service
@Transactional
public class UserService implements IUserService{

    @Autowired
    private UserDAO         userDAO;

    @Override
    public User findUser(String email) {
        return this.getUserDAO().findById(email);
    }

    public UserDAO getUserDAO() {
        return this.userDAO;
    }

    public void setUserDAO(UserDAO userDAO) {
        this.userDAO = userDAO;
    }
}

最後に、DAO の実装:

package com.dao.user;

@Repository("userDAO")
@Transactional
public class UserDAOImpl implements UserDAO {

    private SessionFactory  sessionFactory;

    @Autowired
    @Resource(name = "sessionFactory")
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @Override
    public User findById(String id) {
        try {
            User instance = (User) this.sessionFactory.getCurrentSession().get("com.dao.user.User",id);
            return instance;
        } catch (RuntimeException re) {
            throw re;
        }
    }
}

そしてここで stackTrace :

助けてくれてありがとう ！

わかりました、それで私はconfをきれいにして今持っています:

DAO の場合:

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver">
        </property>
        <property name="url"
            value="jdbc:mysql://xxxxx:3306/db?zeroDateTimeBehavior=convertToNull&amp;autoReconnect=true">
        </property>
        <property name="username" value="xxxx"></property>
        <property name="password" value="xxxx"></property>
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
                <value>
                    com/dao/user/User.hbm.xml
                </value>                        
            </list>
        </property>
    </bean>

    <context:component-scan base-package="com.dao" />
    <context:annotation-config />
    <tx:annotation-driven transaction-manager="hibernateTransactionManager" proxy-target-class="true"/>

    <bean id="hibernateTransactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>

ビジネス層の場合: 

<context:component-scan base-package="com.services" />
<context:annotation-config />

DAO から @Transactional アノテーションを削除します。

私はまだ得る：

Ok ！進んでいます！私は何かを疑い、それが確認されました。わかりましたので、私が皆さんに与えた例では、DAO 構成の 1 つだけを示しています。別の DAO 構成があります (2 つのデータベースがあります)。

だから、私が追加しなければならないようです

<tx:annotation-driven transaction-manager="hibernateTransactionManager"/>

私のサービス構成に。そう ：

<context:component-scan base-package="com.services" />
<context:annotation-config />  
<tx:annotation-driven transaction-manager="hibernateTransactionManager"/>

そしてそれは機能します（ただし、1つのデータベースに対してのみ）。データベース1のconfには次のものがあります：

 <tx:annotation-driven transaction-manager="hibernateTransactionManager"/>

データベース2のconfには次のものがあります:

 <tx:annotation-driven transaction-manager="hibernateTransactionManagerA"/>

両方をサービス conf に追加しようとしました:

    <context:component-scan base-package="com.services" />
    <context:annotation-config />  
    <tx:annotation-driven transaction-manager="hibernateTransactionManager"/>
    <tx:annotation-driven transaction-manager="hibernateTransactionManagerA"/>

しかし、最初のデータベースのみが機能しており、2 番目のデータベースの DAO にアクセスしようとすると、セッション エラーが発生します (これは理にかなっています。最初のトランザクション マネージャーのみが使用されていると思います)。

編集：

わかりました、マルチデータソースに関するドキュメントを読んだ後、追加する必要がありました:

<qualifier value="managerTransactionA"/> 
<qualifier value="managerTransactionB"/>

私の2つの休止状態のマネージャートランザクションBeanに。そして、適切なトランザクションを追加する必要がありました:

@Transactional("managerTransactionA")
or
@Transactional("managerTransactionB")
