ServiceMix /蓝图/ JPA集成
ServiceMix /蓝图/ JPA集成
提问于 2013-07-11 23:49:15
我花了一周的时间尝试将JPA / ServiceMix 4.5.1 /camel-jpa2.10.4/ Blueprint集成在一起。我目前正在使用OpenJPA，但并没有绑定到它。servicemix使用的aries jpa版本是0.3.0。
我不能通过的堆栈跟踪是：

[...]我尝试过几种不同的方法。以下是我当前的配置：
persistence.xml：
<persistence-unit name="customer1" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/prototypedb)</jta-data-source>
<class>...</class>
</persistence-unit>camel-context.xml
<service id="PrototypeDB" interface="javax.sql.DataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jdbc/prototypedb"/>
</service-properties>
<bean class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/prototype"/>
<property name="username" value="root"/>
<property name="password" value="..."/>
</bean>
</service>
<service ref="workoutEntity" interface="..."/>
<bean id="workoutEntity" class="...">
<jpa:unit index="0" unitname="customer1" />
<tx:transaction method="*" value="Required"/>
</bean>实体Bean (用groovy编写)
@Entity
@Table(name='customer1')
@Slf4j
class WorkoutEntity implements IWorkoutEntity{
private EntityManager entityManager
WorkoutEntity(final EntityManagerFactory entityManagerFactory) {
this.entityManager = entityManagerFactory.createEntityManager()
}
@Handler
void create( @Body final String input) {
// ...
}
}我尝试过多种不同的DataSource实现，包括BasicDataSource、org.springframework.jdbc.datasource.SimpleDriverDataSource，和com.mysql.jdbc.jdbc2.optional.MysqlDataSource.所有这些都会导致IllegalArgumentException。
我还尝试放弃使用JNDI，而是直接在persistence.xml中定义数据源。这会导致ClassNotFoundException出现在OpenJPA包中，因为它没有导入mysql驱动程序。我更希望在我的camel-context.xml中定义它，并且不希望重新捆绑OpenJPA jar。

您可能还需要安装aries JNDI特性。这有助于通过JNDI查找调用OSGi服务。这应该是缺失的部分。
