如何使用Jackrabbit独立的MySQL持久性管理器

标签: java jackrabbit

我使用默认配置成功使用Apache Jackrabbit 2.4.3和2.6.0(两种情况下都是独立服务器),因此存储库存储在文件系统中。

如何让它连接到MySQL后端呢?我不需要担心迁移,只需将其设置为全新安装。

尝试以下步骤后,Jackrabbit无法正确启动或填充数据库中的DATASTORE表,我在日志中发现此错误:

ERROR [main] RepositoryImpl.java:366           failed to start Repository: Cannot instantiate persistence manager org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager
    javax.jcr.RepositoryException: Cannot instantiate persistence manager org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager
    [... oodles of backtrace cut ...]

到目前为止我做了什么:

我已经创建了Jackrabbit数据库/用户,我可以连接到没问题:

mysql -D jackrabbit -u jackrabbit -h localhost -pjackrabbit

我开始使用干净的平板(空/ var / jackrabbit目录),但配置文件来自此处:https://raw.github.com/wiki/jackalope/jackalope/files/repository.xml

这是我正在使用的启动脚本:https://github.com/sixty-nine/Jackrabbit-startup-script

这是运行的java进程:

java -XX:MaxPermSize=128m -Xmx512M -Xms128M -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1111 -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.password.file=/opt/jackrabbit/startup/jmx.user -Dcom.sun.management.jmxremote.access.file=/opt/jackrabbit/startup/jmx.role -jar /opt/jackrabbit/jackrabbit-standalone-2.6.0.jar -h 127.0.0.1 -p 8080

我认为我不够重要,但我使用的是MySQL 5.5.28-1。

我在2.4.3和2.6.0都遇到了上述问题。

此外:

java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

另外我随后在Debian上安装了MySQL JDBC库:

apt-get install libmysql-java

4 个答案:

答案 0 :(得分:1)

MySqlPersistenceManager尝试加载驱动程序类org.gjt.mm.mysql.Driver,这是非常古老的。尝试使用更新的驱动程序类,而不是类com.mysql.jdbc.Driver。为此,您需要在repository.xml和所有workspace.xml文件中配置持久性管理器,如下所示:

<PersistenceManager ...>
    ...
    <param name="driver" value="com.mysql.jdbc.Driver"/>
</PersistenceManager>

答案 1 :(得分:1)

为了使用Apache Jackrabbit-standalone加载MySQL驱动程序。您需要更新MANIFEST.MF中的jackrabbit-stabndalone-x.x.x.jar

只需在文件底部添加一个Class-Path语句,例如:

  

Class-Path:lib / mysql-connector-java-5.1.25-bin.jar

我遇到了和你一样的问题,这是我能够识别MySQL驱动程序类的唯一方法。

答案 2 :(得分:0)

回答我自己的问题,虽然它没有直接回答它:

我没有尝试使用jackrabbit-standalone版本,而是按照此处的说明成功地让它在Tomcat下运行:

https://github.com/jackalope/jackalope/wiki/Running-jackrabbit-in-tomcat-with-mysql

这给了我我需要的东西;一个连接到MySQL数据存储的工作Jackrabbit实例。虽然这对任何碰到这个并且特别需要使用Jackrabbit独立的人没有帮助,但我会说在Tomcat下设置它对我来说更容易,所以值得考虑。

请进行以下活动。

  1. Un-jar独立服务器jar(在我的例子中是:jackrabbit-standalone-2.8.3)。你会看到很多文件夹。其中你会找到两个文件夹。 1.com 2. org。

  2. Un-jar mysql-connector-java-5.1.30-bin。再次,你会发现上面提到的两个文件夹。进入两个文件夹并复制git(org)和mysql(com)

  3. 分别粘贴在步骤1的文件夹中。并重新启动独立服务器。
