我在Linux Mint机器上安装了gerrit,我试图使用mysql数据库连接进行HTTP身份验证。 但是当我尝试启动gerrit时,我收到以下错误:

我在mysql-connector-java-5.1.28.jar
中复制了/usr/share/java
但仍然存在此错误。
有人可以指点我的方向吗?
答案 0 :(得分:1)
最好不要让/usr/share/java
保持原状。下次升级时,放在那里的任何东西都会丢失。相反,为您的驱动程序定义自己的公共位置。如果它只适合您,您所在位置的子目录可能会很好:mkdir ~/jdbc
。
然后将.jar复制到该位置的jdbc驱动程序。
然后,根据您运行Java代码的方式,您必须弄清楚如何将jar包含在类路径中。
java
启动独立java程序,然后使用-cp
参数选项。/usr/share/java
相同的原因,我建议不要这样做。实际上,tomcat允许您将CATALINA_HOME与CATALINA_BASE分开以解决该问题。无论哪种方式,似乎异常都是从一个简单的main
生成的,而不是一个Web应用程序,因此我假设您可以选择第一个选项。
