Was vermisse ich hier?

In diesem forum eine Lösung hat:

http://www.coderanch.com/t/581183/Spring/Spring-Hibernate-transaction-Management-unwrap

Gibt es Duplikate bei auch SO:

Quelle suite spring3 + Hibernate4 + maven 3 + MySQL 5

hier wird nicht tatsächlich mein problem gelöst, aber machte mich herausgefunden, dass ich fehlte die Verbindungs-pooling, Der C3P0 Verbindungs-pooling.

InformationsquelleAutor duffymo

Meine Umgebung: Hibernate5.2.5 + Spring4.3.4

Dies ist der Grund, warum ich stieß auf dieses:
Ich konfigurieren dabatabase info in hibernate.cfg.xml:

     <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
     <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/Elec</property>
     <property name="hibernate.connection.username">root</property>
     <property name="hibernate.connection.password">123</property>

Dies ist, wie ich das Problem gelöst:
Ich erstellen Sie eine bean mit der id der dataSource in spring xml-Konfigurationsdatei,dann konfigurieren Sie die Datenbank-Infos in die Bohne.Und ich dataSource-Referenz durch ein Objekt mit der Eigenschaft dataSource in die bean mit der id sessionFactory:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/Elec"/>
    <property name="username" value="root"/>
    <property name="password" value="123"/>
</bean>



<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
</bean>

<bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>
