web-services - 为什么 Tomcat 7 部署的应用程序返回 HTTP 状态 404？

Question

同事们，谁能帮我在tomcat服务器上部署应用程序...

情况是:1.我已经在tomcat上部署了app。但是管理面板中没有取消部署按钮。2. 我运行 mvn clean package tomcat7:redeploy 结果是:

[INFO] Deploying war to http://localhost:8080/app-ws Uploading: http://localhost:8080/manager/text/deploy?path=%2Fapp-ws&update=true Uploaded: http://localhost:8080/manager/text/deploy?path=%2Fapp-ws&update=true (11702 KB at 17334.8 KB/sec)

[INFO] tomcatManager status code:200, ReasonPhrase:OK [INFO] OK - Deployed application at context path /app-ws [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 01:08 min [INFO] Finished at: 2015-07-28T11:46:44+03:00 [INFO] Final Memory: 29M/260M [INFO] ---

---

看起来不错，但是:

1. 当我运行 http://localhost:8080/app-ws 时我收到 HTTP 状态 404

2. 在 C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps 中我有带有实际创建日期的 app-ws.war

3. 在同一个文件夹中，我有 C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\app-ws 文件夹，但没有实际日期
4. 在 C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\server.xml 中我有下一个属性.可能是这里的问题？

您知道如何在描述的案例中正确部署和运行应用程序(网络服务)吗？

感谢您的任何意见和建议。

更新

1. 我取消部署我的应用程序。
2. C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps 中没有 app-ws 文件夹和 war
3. 运行 mvn clean package tomcat7:deploy and receive

[INFO] <<< tomcat7-maven-plugin:2.2:deploy (default-cli) < package @ app-ws <<<

通过添加

Answer 1

我也遇到了同样的问题。然后我做了以下事情

1. 转到tomcat管理页面并转到“http://localhost:8000/manager/html”然后取消部署我的项目。或者从 Web 应用程序中手动删除项目(project.war 和项目文件夹)。
2. 在 tomcat web apps 文件夹中再次部署项目。

请注意，这适用于服务器成功部署应用程序且没有任何错误的情况。
