全部

当尝试使用Class.forName("com.mysql.jdbc.Driver")加载Driver类时,出现了com.mysql.jdbc.Driver异常.我已经编写了一个自定义Eclipse插件,并想访问我的自定义Eclipse插件中的数据库.

I am getting the com.mysql.jdbc.Driver exception when trying to load the Driver class using Class.forName("com.mysql.jdbc.Driver"). I have written a custom Eclipse plugin and wanted to access the database in my custom Eclipse plugin.

我尝试了以下2个选项,但两个选项显然都失败了:
1>将mysql连接JAR文件添加到Eclipse插件构建路径
2>将连接器JAR文件添加为库,并添加到插件的运行时类路径

I have tried following 2 options, both obviously failed:
1 > Adding the mysql connection JAR file to the Eclipse plugin build path
2 > Adding the connector JAR file as library and adding to the plugin's runtime classpath

有人可以帮我吗?

这是日志:

推荐答案

我建议为MySQL驱动程序创建自己的OSGi捆绑包,请参见 http://wiki.eclipse.org/Create_and_Export_MySQL_JDBC_driver_bundle .然后,您必须在捆绑软件的plugin.xml中设置对创建的mysql-bundle的依赖.

I recommend to create your own OSGi-Bundle for the MySQL Driver, see http://wiki.eclipse.org/Create_and_Export_MySQL_JDBC_driver_bundle for a how-to. Afterwards you have to set a dependency in your plugin.xml of your bundle to the created mysql-bundle.

此外:请在OSGi环境中使用的不是DriverManager,而是数据源的实现.

In addition: Please use in an OSGi environment not the DriverManager but an implementation of DataSource.
