【中文标题】Pentaho 错误 - ConnectionServiceImpl.ERROR_0009 - 连接到数据库 [null] 失败

【英文标题】：Pentaho Error - ConnectionServiceImpl.ERROR_0009 - Connection to database [null] failed

【发布时间】：2017-07-08 15:38:17

【问题描述】：

我正在尝试设置与 mysql 服务器（本地主机）的 pentaho 连接。但是，当我尝试测试连接时，会出现此错误 "ConnectionServiceImpl.ERROR_0009 - Connection to database [null] failed"。关于服务器的信息应该是正确的。 资料图片：

[我在 MySQL 中没有 root 帐户的密码] 和 MySQL 连接器文件已插入到 pentaho 服务器 lib 文件夹中。

连接器文件夹图片：

我查找了日志文件，并发现了有关我的连接测试的信息：

我已经寻找了很多解决方案，但我没有找到任何东西。它缺少什么？

【问题讨论】：

当您搜索 Error_0009 时，这似乎是最受欢迎的问题。 - 为什么不使用 MySQL 数据库类型？ - 如果您需要通用数据库连接，请检查您的 Driver.class。 mysql-conector-java 包含两个驱动程序：com.mysql.jdbc.Driver 和 org.gjt.mm.mysql.Driver。通过提供提示来帮助 Kettle。

因为 MySQL 数据库类型没有出现在我的列表中。我已按照所有程序安装它，但没有任何结果。我也尝试过提示但没有发生任何事情。

【参考方案1】：

同样的问题，我解决了复制 mysql-connector-java-5.1.42-bin.jar 的问题

tomcat/lib 架构工作台/lib 架构工作台/驱动程序 pentaho-server/data/lib（不确定是否有用） 在pentaho文件夹内的文件夹下名为'jdbc'的文件夹中（我使用了文件系统的搜索功能）

我已停止服务器并重新启动服务器。

这样在照片上的Database Type中出现了“Mysql”选项。

最后我使用 org.gjt.mm.mysql.Driver 作为驱动程序类名字段。

【参考方案2】：

这里有几件事：

您的 MySQL 服务器是否在 localhost 上运行？它是否在端口3306 上运行？ 您确定这是您显示的正确连接吗？在日志中显示Cannot initialize org.gjt.mm.mysql.Driver（旧版本），但在连接窗口中您提供了com.mysql.jdbc.Driver（新版本）。为什么不同= 在我看来，您使用了错误的驱动程序类。连接是否在其他地方定义？

编辑

“pentaho driver jars directory”的第一个结果是this page。它指出外部 jar 必须进入目录

pentaho/jdbc-distribution

之后必须执行一个文件

distribute-files.bat <name of JDBC driver JAR>

然后重新启动服务器。此外，还有您使用的应用程序的文件夹列表。

【讨论】：

是的，我的服务器 si 在 localhost 上运行，端口是 3306。我尝试将旧版本和新版本 (org.gjt.mm.mysql.Driver) 初始化，但错误是相同的。我使用的其他工具（水壶，模式工作台）不需要指定驱动程序类，我只需将 jar 文件放在 lib 文件夹中，所以我很确定驱动程序可以工作，但我不知道如何交给 petaho 服务器
