web-applications - tomcat中的默认网络应用程序

Question

这几天我一直在寻找解决方案。我的问题是..我必须在 tomcat 中部署一个项目并将其作为默认的 webapp。我所做的是复制我的 war 文件并将其放在 tomcat/webapps 文件夹中。启动tomcat并将端口更改为默认值。现在我可以通过 http://localhost/myapp 访问我的应用程序.我想要的是在http://localhost看到我的申请.我怎样才能做到这一点？

Answer 1

我能够通过在 server.xml 文件中的 Host 下添加具有 path=""属性的“Context”元素来做到这一点。

            <Context path="" docBase="/usr/local/tomcat/mywebapps/myapplication">
                <WatchedResource>WEB-INF/web.xml</WatchedResource>
            </Context>

注意:我使用的是 Tomcat 7。此外，我必须将我的 webapp 移动到与默认 webapps 文件夹不同的位置。我还删除了 tomcat 提供的默认 webapps。但即使不删除它们，此解决方案也能奏效。

这里是我的server.xml的内容，供引用。希望这会有所帮助。
