带有 Hibernate 的 Mule JPA 模块

Question

尝试在 Mule 中使用 Hibernate 实现 Mule 模块 JPA，但无法使用 .当我签入数据库时​​，没有插入任何值。我引用了此链接，但无法实施此链接中给出的解决方案，Mule JPA persist is not inserting or updating。

有人可以详细说明或提供其他建议吗？谢谢。

   <spring:beans>
    <spring:import resource="classpath:Spring/applicationContext.xml" />

    </transactional>
         <logger  message="#[message.payload]" level="INFO" doc:name="After Transaction"/>
        </flow>
</code>

和 Persistence.xml

<code>
<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_2_0.xsd"
        version="2.0">

    <persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
         <provider>org.hibernate.ejb.HibernatePersistence</provider>
          <class>org.Location</class>
        <properties>
            <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
            <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/xxxx" />
            <property name="hibernate.connection.username" value="xxx" />
            <property name="hibernate.connection.password" value="xxxx" />

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>

</persistence>
</code>

还有applicationcontext.xml，

<code>
      <context:spring-configured/>
            <context:annotation-config />
        <bean id="entityManagerFactory"
      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean>
            <property name="persistenceUnitName" value="default" />
            <property name="jpaVendorAdapter">
                <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                 <property name="showSql" value="true"/>
                    <property name="generateDdl" value="true"/>
                </bean>
            </property>
        </bean>
            <bean class="org.springframework.orm.jpa.JpaTransactionManager"
                  id="transactionManager">
                <property name="entityManagerFactory" ref="entityManagerFactory"/>
            </bean>

           <bean id="sessionFactory" factory-bean="entityManagerFactory" factory-method="getSessionFactory"/>

            <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>

    </code>

Answer 1

这是另一个替代示例 mule_spring_hibernate 。经过长时间的努力让正确的库一起工作，我决定我需要创建一个演示项目并分享

请注意 mule-deploy.properties 文件中的 loader.override=org.hibernate 条目。

Answer 2

作为替代方案，请考虑persisting data via Hibernate from a Mule component。在 Mule 3.6.1 中的工作示例可以在 here 找到。
