I am starting an active mq broker using my own config file:

./apache-activemq-5.6.0/bin/activemq console xbean:custom-broker.xml

The broker is using some classes I have defined which reside in a jar. For a while now I was just sticking the jar in the activemq lib folder, and everything worked fine. However I would now like for active mq to pick up the jar from a different folder, something which the --extdir option claims to be capable of doing. However I can't get it to work. I am executing the command:

./apache-activemq-5.6.0/bin/activemq console xbean:custom-broker.xml --extdir ../mylib/

where the jar in question is located in mylib, and am getting ClassNotFoundException every time.

What am I missing?

解决。--extdir 确实按预期工作，结果有人将其中一个包的名称更改了 1 个字符，这就是为什么 activemq 无法在 jar 中找到有问题的类：P。还值得注意的是，如果您想将多个文件夹添加到活动 mq 的类路径，那么您需要重复 --extdir 多次，如“--extdir foldr1 --extdir foldr2”，如此处所述：
