java - 更改 jetty 默认端口

Question

Jetty 默认端口是 8080，但我想将默认端口更改为其他端口(9999)。

我阅读了一些教程，他们说几乎所有配置信息都默认保存在文件 jetty.xml 中，该文件位于 $JETTY_HOME/etc/ 下.然后，将属性 jetty.port 更改为 9999。但是，当我打开该文件时，我在 jetty.xml 中找不到 jetty.port 属性。我目前使用的是Jetty-9.2.1，端口在8080。

我在 jetty-http.xml 文件下找到了 jetty.port 属性。即使我在 jetty-http.xml 文件中将端口更改为 8090，jetty 仍然在 8080 端口运行。

我还被建议使用集成测试来配置 Jetty 以使用其他端口。项目中有一个 integration-tests.properties 文件。也许解决方案是在此文件中将 jetty.port 设置为 9999？

integration-tests.properties:

host = localhost
port = 9999

Answer 1

如果你像这样从命令行启动它时设置端口，它是否有效:

java -jar start.jar -Djetty.port=9999
