java - Tomcat 返回 http 状态错误：401，原因短语：未经授权

问题描述

我将 Intellij IDEA 与 Tomcat 和 Maven 一起使用。当我运行重新部署时，我收到以下错误。我如何解决它？我试着查了一下，似乎没有一个答案适合。

解决方案

尝试在您的 maven 的 .m2/settings.xml 或 conf/senttings.xml 中定义您的 tomcat 的凭据

<server>
        <id>TomcatSever</id>
        <username>admin</username>
        <password>admin</password> 
</server>
