ServiceMix 5.3.0 JPA问题

我在ServiceMix中启动jpa包时遇到问题。使用EntityManager注入时会出现问题，而注入EntityManagerFactory工作正常。知道什么是错的吗？

我的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
             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">
    <persistence-unit name="MyUnit" transaction-type="JTA">
        <jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/oracleds)</jta-data-source>

        <class>sandbox.MyEntity</class>

        <properties>
            <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema"/>
        </properties>

    </persistence-unit>

</persistence>

blueprint.xml：

<?xml version="1.0" encoding="UTF-8"?>
<blueprint
        xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
        xmlns:jpa="http://aries.apache.org/xmlns/jpa/v1.1.0"
        xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd"
>

    <bean id="MyDAO" class="sandbox.dao.impl.MyDAOImpl">
        <tx:transaction method="*" value="Required" />
        <jpa:context property="em" unitname="MyUnit" />
        <!--<jpa:unit property="emf" unitname="MyUnit" />-->
    </bean>

    <service ref="MyDAO" interface="sandbox.dao.MyDAO" />

</blueprint>

部署捆绑包失败，但出现以下异常：

MANIFEST.MF导入：

Import-Package: javax.persistence;version="[1.1,2)",org.osgi.service.blueprint;version="[1.
 0.0,2.0.0)"

提供javax.persistence包的Karaf包：

答案 0 :(得分：1)

请检查您的类路径依赖项：javax.persistence.criteria.CriteriaUpdate NoClassDefFoundError已添加JPA 2.1。但根据persistence.xml，JPA 2.0在您的应用程序中使用。

修改

版本＆gt; = 1.0.0的Aries依赖于JPA 2.1，请参阅其pom.xml文件here，您应该相应地更新MANIFEST.MF导入。
