Question

我正在使用Jetty 9，我有jetty.base和jetty.home，我想知道什么时候我开始码头，它以什么样的顺序称它为jetty.base和jetty.home，我的意思是它会从jetty.base或jetty.home读取库吗？或者检查属性形式jetty.base然后从jetty.home检查，反之亦然，如果你知道任何有用的文章，或任何方式在我的码头内测试它，我很欣赏。

使用--list-config选项查看输出。它告诉你订单。

$ java -jar /opt/jetty/jetty-distribution-9.3.0.v20150612/start.jar --list-config

Java Environment:
-----------------
 java.home = /home/joakim/java/jvm/jdk-8u45/jre

 jetty.base = /home/joakim/static-base

Config Search Order:
--------------------
 <command-line>
 ${jetty.base} -> /home/joakim/static-base

请注意标题为“配置搜索顺序”的部分？

我怎样才能弄清楚在码头上运行jetty.base和jetty.home的顺序？
