Answer 1

我的projectname是:DemoApplication，首先这个上下文根被部署的路径是，http://localhost:8080/DemoApplication，第二次是，http://localhost:8080/controller？

您需要修复web应用程序（DemoApplication）的根上下文以修复URL，您可以通过以下选项之一来实现：

（1）在Tomcat中将根上下文设置为demoapplication，如下所示

（2）如果您使用的是Maven，可以通过在pom.xml中添加以下标记来修复war名称：

<build>
    <finalName>DemoApplication</finalName>
</build>

完成上述任一选项后，您应该能够始终使用以下url访问应用程序控制器：

http://localhost:8080/demoapplication/controller
