使用logstash5.6.4版本从达梦数据库版本8抽取数据到es，报驱动不能加载的问题

使用logstash5.6.4版本从达梦数据库版本8抽取数据到es，日志报不能加载驱动类的错误，核对包路径、权限都没问题；同路径下的mysql驱动包是可以加载的；logstash里配置的达梦信息如下：

日志报错信息如下：

dm.jdbc.driver.DmDriver not loaded，驱动没有加载，是否添加了jar包。

jdbc_driver_class => "dm.jdbc.driver.DmDriver"
改成
jdbc_driver_class => "Java::dm.jdbc.driver.DmDriver"
试试，我是这么解决的
