Tomcat war在本地运行，但不在heroku上或通过webapp-runner运行

Question

我有一个非常简单的war文件，当手动复制到Tomcat的webapps文件夹时工作正常（如http://localhost:8080/helloworld-0.0.1-SNAPSHOT/rest/）。但是当部署到heroku（https://foobar.herokuapp.com/helloworld-0.0.1-SNAPSHOT/rest/）或在嵌入模式下尝试本地运行（同上的localhost链接）时，浏览器上的 404错误（请求的资源不可用）：

java -jar target/dependency/webapp-runner.jar target/*.war

我尝试了heroku网站上记录的所有可能的部署：

• CLI
• Maven Plugin
• 的webapp浇道

只是将战争复制到本地运行的tomcat服务器似乎是可行的。这是我的pom.xml

这是我的web.xml（关键部分）：

    </servlet>
