linux - 我如何确定在 jetty 中运行 jetty.base 和 jetty.home 的顺序？

Question

我正在使用 Jetty 9，我有 jetty.base 和 jetty.home，我想知道我什么时候启动 jetty，它以什么样的顺序调用 jetty.base 和 jetty.home，我的意思是一开始它将从 jetty.base 或 jetty.home 读取库？或者它检查属性表单 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，或者任何在我的 jetty 内测试它的方法，我将不胜感激。

使用--list-config 选项并查看输出。它会告诉您顺序。

$ 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
 java.vm.vendor = Oracle Corporation
 java.vm.version = 25.45-b02
 java.vm.name = Java HotSpot(TM) 64-Bit Server VM
 java.vm.info = mixed mode
 java.runtime.name = Java(TM) SE Runtime Environment
 java.runtime.version = 1.8.0_45-b14
 java.io.tmpdir = /tmp
 user.dir = /home/joakim/static-base
 user.language = en
 user.country = US

Jetty Environment:
-----------------
 jetty.version = 9.3.0.v20150612
 jetty.tag.version = master
 jetty.home = /opt/jetty/jetty-distribution-9.3.0.v20150612
 jetty.base = /home/joakim/static-base

Config Search Order:
--------------------
 <command-line>
 ${jetty.base} -> /home/joakim/static-base
 ${jetty.home} -> /opt/jetty/jetty-distribution-9.3.0.v20150612
