我的应用程序在不设置任何上下文根的情况下与 payara 服务器一起使用，但 payara micro 将默认上下文根设置为我的 war 文件的名称。如果 ot payara micro ，如何将上下文根设置为空？

一种方法是将战争名称设置为 ROOT.war 但使用该名称我在部署时会出现以下错误。我尝试将 xerces-2.9.1 jar 放入 --addLibs 但不起作用。

首先，您不应该仅仅因为您将应用程序重命名为 ROOT.war 而出现错误。如果在最新版本的 Payara Micro 上发生这种情况，您应该提出一个 github 问题：https ://github.com/payara/Payara/issues

现在回到问题。--contextroot您可以使用设置为的命令行选项设置上下文根/：

java -jar payara-micro.jar --contextroot / app.war

如果您部署多个应用程序或资源，您可以在部署文件的名称中指定上下文根，用冒号（或 Windows 上的分号）分隔，例如：

java -jar payara-micro.jar app.war:/

这是关于此的完整文档：https ://docs.payara.fish/community/docs/5.2020.4/documentation/payara-micro/deploying/deploy-cmd-line.html#define-context-root
