Answer 1

根据错误消息，您似乎没有在Tomcat中定义上下文。

将名为 context.xml 的文件包含在META-INF文件夹中，内容为：

<?xml version="1.0" encoding="UTF-8"?>

<Context path="/Own2"/>

来自tomcat文档：

Tomcat Context Container Documentation

可以明确定义单个上下文元素：

在应用程序内的/META-INF/context.xml中的单个文件中   文件。可选地（基于主机的copyXML属性），这可以是   复制到$ CATALINA_BASE / conf / [enginename] / [hostname] /并重命名为   应用程序的基本文件名加上＆＃34; .xml＆＃34;扩展
