OSGi中的OpenJPA找不到MySQL JDBC连接器bundle



我目前正在Felix(v4.0.3)上做一个OSGi项目。我需要使用JPA,所以我安装了Apache Aries JPA捆绑包。我还安装了OpenJPA,我需要它使用MySQL连接器捆绑包连接到MySQL数据库。不幸的是,它不起作用,OpenJPA说它找不到MySQL JDBC类,我也不知道是什么坏了,也许我做错了什么。我将在下面解释我安装了什么,以及persistence.xml文件和我得到的实际异常。

以下是我安装的ApacheAries捆绑包的列表:

  1. org.apache.aaries.jpa.api-0.3.jar
  2. org.apache.aries.jpa.container.text-0.3.jar
  3. org.apache.aries.jpa.container-03.jar
  4. org.apache.aries.util-0.4.jar

然后我安装了那些ApacheAries JPA捆绑包的依赖项。我从Springsource下载了它们:

  1. com.springsource.javax.transaction-1.10.jar
  2. com.springsource.org.apache.log4j-1.2.16.jar
  3. com.springsource.slf4j.api-1.6.1.jar
  4. com.springsource.slf4j.log4j-1.6.1.jar
  5. javax.persistence_2.0.4.v201112161009.jar(如果重要的话,这个来自EclipseLink)

我还安装了OpenJPA及其所有依赖项。我在apache-openjpa-2.2.0下载文件夹的lib文件夹中发现了捆绑包2到5(commons-*)。我在这里下载了Serp,因为在lib文件夹中找到的jar不是OSGi捆绑包。最后,我在Springsource中找到了最后两个bundle(#7和#8):

  1. openjpa-2.2.0.jar
  2. commons-collections-3.2.1.jar
  3. 通用-dbcp-1.4.jar
  4. commons-lang-2.4.jar
  5. 公共泳池-1.5.4.jar
  6. org.apache.servicemix.bundles.serp-1.13.1_4.jar
  7. com.springsource.javax.servlet-2.5.0.jar
  8. com.springsource.org.objectweb.asm-3.2.0.jar

一旦我最终安装了OpenJPA,我仍然需要MySQL JDBC驱动程序捆绑包,它也是我从Springsource存储库中获得的,以及它的公共日志依赖项:

  1. com.springsource.com.mysql.jdbc-5.1.6.jar
  2. com.springsource.org.apache.commons.loggin-1.1.1.1.jar

现在,安装的捆绑包列表越来越大。我说我安装了OpenJPA,但这只是因为我不知道如何使用Aries的任何其他提供商。我最初想使用EclipseLink,但显然Apache Aries没有检测到它是一个提供商,根据这个博客,你必须制作另一个包含你自己的激活程序的捆绑包,Aries才能注意到EclipseLink。我试过了,但没有成功,所以我转而使用OpenJPA。

现在我有两个问题:

  • 如何让OpenJPA注意到我的MySQL捆绑包

或者:

  • 如何让Apache Aries注意到EclipseLink

这是我使用的persistence.xml文件:

<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" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="userManager.model" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<class>org.project.dao.entity.UserEntity</class>
<properties>
<property name="openjpa.ConnectionDriverName" value="com.mysql.jdbc.Driver" />
<property name="openjpa.ConnectionURL" value="jdbc:mysql://localhost:3306/usermanager?autoReconnect=true" />
<property name="openjpa.ConnectionUserName" value="root" />
<property name="openjpa.ConnectionPassword" value="root" />            
</properties>
</persistence-unit>
</persistence>

当我的DAO类的以下构造函数被执行时,会发生错误:

@PersistenceContext(unitName="userManager.model")
private EntityManager em;
private EntityManagerFactory emf;
public UserDAOBean() {
em = emf.createEntityManager();
}

以下是我在OpenJPA找不到MySQL时遇到的错误。当然,值得一提的是,URL和用户名/密码都有效:

<openjpa-2.2.0-r422266:1244990 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: There were errors initializing your configuration: <openjpa-2.2.0-r422266:1244990 fatal user error> org.apache.openjpa.util.UserException: A connection could not be obtained for driver class "com.mysql.jdbc.Driver" and URL "jdbc:mysql://localhost:3306/usermanager?autoReconnect=true".

PS:由于垃圾邮件限制,我无法发布到Aries、OpenJPA或EclipseLink的链接,对不起:/

感谢Holly Cummins,经过几个小时的研究,我终于找到了解决问题的方法。我将在下面详细介绍,这将是一个非常长的答案。

如果您想将EclipseLink与ApacheAries一起使用(我发现它的安装比OSGi的OpenJPA简单几个数量级,因为它只包含在5个捆绑包中),您必须直接从Apache签出EclipseLink-Aryes适配器,因为它还没有发布。

转到适当的文件夹并执行以下命令以获取它:

svn checkout https://svn.apache.org/repos/asf/aries/trunk/jpa/jpa-container-eclipselink-adapter/

您应该得到一个名为jpa-container-eclipselink adapter的文件夹。现在,假设您使用的是Linux并安装了Maven,运行以下命令:

cd jpa-container-eclipselink-adapter
mvn clean install

一旦Maven成功编译了适配器的源代码,您将使用路径在Maven存储库中找到它

<maven-repo>/org/apache/aries/jpa/org.apache.aries.jpa.eclipselink.adapter/0.3.1-SNAPSHOT/org.apache.aries.jpa.eclipselink.adapter-0.3.1-SNAPSHOT.jar

您必须将此捆绑包与其他捆绑包一起部署(将其复制到Felix的bundle文件夹中)。

这就是EclipseLink的部分,现在为了让你的坚持真正奏效,你必须使用白羊座的蓝图。以下是您需要从[http://aries.apache.org/downloads/currentrelease.html](Apache Aries下载页面)

  1. org.apache.aries.blueprint
  2. org.apache.aries.proxy
  3. org.apache.aries.jndi.api
  4. org.apache.aries.jndi
  5. org.apache.aries.blueprint
  6. org.apache.aries.jpa.api
  7. org.apache.aries.jpa.container.text
  8. org.apache.aries.jpa.container
  9. org.apache.aries.transaction.blueprint
  10. org.apache.aries.transaction.manager(这个在他们的网站上列出了两次,只是重复)
  11. org.apache.aries.util

下载完Aries后,您仍然需要依赖项(从SpringSource获取)。这些是SLF4J、Log4J、SLF4J Log4J Binding和javax.transaction 1.1 API的捆绑包。

  1. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.slf4j.api&版本=1.6.1
  2. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.slf4j.log4j&版本=1.6.1
  3. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.javax.transaction&版本=1.1.0
  4. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.org.apache.log4j&版本=1.2.16

您还需要来自EclipseLink的捆绑包(您需要OSGi捆绑包版本)

http://www.eclipse.org/eclipselink/downloads/

打开zip并获得以下文件:

  1. org.eclipse.persistence.antlr
  2. org.eclipse.persistence.asm
  3. org.eclipse.persistence.core
  4. org.eclipse.persistence.jpa
  5. javax.persistence

最后,假设您想要使用MySQL数据库,您将需要MySQL JDBC驱动程序的捆绑包(从Springsource下载)

  1. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.com.mysql.jdbc&版本=5.1.6
  2. http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.org.apache.commons.logging&版本=1.1.1

一旦安装了所有这些捆绑包,就需要使用将通过JNDI获得的非jta数据源。这里有一个persistence.xml文件,您可以根据需要进行更改:

<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" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="userManager" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<non-jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/userManagerDS)</non-jta-data-source>
<class>com.example.dao.entity.UserEntity</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>  
<!-- EclipseLink should create the database schema automatically -->
<!-- <property name="eclipselink.ddl-generation" value="create-tables" /> 
<property name="eclipselink.ddl-generation.output-mode" value="database" /> -->
</properties>
</persistence-unit>
</persistence>

是否查看非jta数据源标记中的javax.sql.Datasource?这就是我们将使用Blueprint xml定义的内容。为了做到这一点,您首先需要在持久性捆绑包(包含DAO和实体的文件夹)中添加OSGI-INF/bluent/文件夹。这是蓝图xml文件所在的默认文件夹,位于此处的任何xml文件都将被扫描。完成后,创建blueprint.xml文件(名称可以更改)并粘贴(和修改)以下代码:

<bean id="dataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">
<property name="url" value="jdbc:mysql://localhost:3306/usermanager?autoReconnect=true" />
<property name="user" value="root" />
<property name="password" value="root" />
</bean>
<service id="MySQLDataSource" interface="javax.sql.DataSource" ref="dataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jdbc/userManagerDS" />
</service-properties>
</service>
<service id="userDAOService" interface="com.example.dao.remote.UserDAORemote">
<bean class="com.example.dao.beans.UserDAOBean">
<jpa:unit index="0" unitname="userManager" />
</bean>
</service>
</blueprint>

在这里,我们正在做两件事。首先,我们告诉Aries创建userManagerDS数据源,并使用JDBC驱动程序、URL、用户和密码对其进行配置。这与我们在persistence.xml文件中使用的数据源相同。

然后,我们在DAO中注入EntityManagerFactory。我们的DAO是com.example.DAO.beans.UserDAOBean类,我们需要将其名称添加到bean标记中。这个类必须实现一个接口,我们需要将这个接口添加到服务标记中。现在,最后的jpa:unit标记告诉Aries通过使用UserDAOBean的第一个构造函数,注入与名为userManager(与我们在persistence.xml中使用的名称相同)的持久性单元相关的EntityManagerFactory。这是通过使用index="0"属性来完成的。这也意味着您的DAO中必须有一些类似以下的代码:

private EntityManager em;
private EntityManagerFactory emf;
public UserDAOBean(EntityManagerFactory emf) {
this.emf = emf;
this.em = emf.createEntityManager();
}

也可以使用setter注入EMF。以下是帮助您使用蓝图的更多资源:

  • http://aries.apache.org/modules/jpaproject.html
  • http://aries.apache.org/modules/blueprint.html
  • http://mail-archives.apache.org/mod_mbox/aries-user/201104.mbox/%3C15F2C30E-2A71-4320-9992-DBCF181B58E4@gmail.com%3E

可选:请注意,如果您使用的是Felix,添加javax.transaction捆绑包将导致"使用约束冲突",因为系统捆绑包(捆绑包0)也导出此API。您必须通过更改config.properties中的以下行来阻止它导出:

#org.osgi.framework.system.packages=

您必须在此处列出上一个捆绑包导出的所有包的列表。不幸的是,无法"删除"包,您必须重新定义要导出的整个包列表。这是我的,我希望它能有所帮助(是的,它非常非常长):

使用JNDI数据源而不是直接的jdbc连接可能会更好。Aries博客示例有一个blog.datasource捆绑包,该捆绑包使用Blueprint注册数据源。所需捆绑包的列表比您目前拥有的要长,但您可以从博客程序集/目标目录或pom.xml中复制所有捆绑包

或者,白羊座有一个org.apache.Aries.jpa.eclipselink.adapter,它和你链接的文章做同样的事情。白羊座用它来测试eclipselink,所以它肯定会起作用。你也可以看看白羊座的测试,看看它是如何使用的,看看是否有EclipseLink测试可以复制。

使用gemini blueprint dbAccess插件时,事情可能会更容易(http://www.eclipse.org/gemini/dbaccess/),我认为这对白羊座也适用。对于MySQL,请确保包含连接器插件(例如。http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.com.mysql.jdbc&version=5.1.6)。这应该足以让数据库启动并运行,前提是blueprint.xml(使用上面的示例)如上所述正确配置。
