通过 Docker - 404 在 Tomcat 上部署 .war

【问题标题】：Deploying .war on Tomcat via Docker - 404通过 Docker - 404 在 Tomcat 上部署 .war
【发布时间】：2017-11-10 23:37:39
【问题描述】：

我正在从 docker 运行 Tomcat：

docker run -it --rm -p 8888:8080 -v /Users/laura/Desktop/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml:ro tomcat:8.0

我可以正常访问 Tomcat 管理器。我已将 .war 文件复制到 webapps 目录，但 Tomcat 管理器在尝试访问它时给了我 404...部署期间没有错误。

我也尝试过直接在 .war 挂载的情况下运行它：

docker run -it --rm -p 8888:8080 -v /Users/laura/Desktop/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml:ro  -v /Users/laura/Desktop/glossary.war:/usr/local/tomcat/webapps/glossary.war tomcat:8.0

输出如下：

然后我尝试通过 http://localhost:8888/glossary/ 访问它，但它失败并显示 404。

这是 webapp 目录的内容：

root@544c1d9f4a88:/usr/local/tomcat# ls -lh webapps/
total 147M
drwxr-xr-x  3 root root 4.0K Nov  4 21:32 ROOT
drwxr-xr-x 14 root root 4.0K Nov  4 21:32 docs
drwxr-xr-x  6 root root 4.0K Nov  4 21:32 examples
drwxr-xr-x  5 root root 4.0K Nov 10 23:05 glossary
-rwxr-xr-x  1 root root 147M Nov 10 23:05 glossary.war
drwxr-xr-x  5 root root 4.0K Nov  4 21:32 host-manager
drwxr-xr-x  5 root root 4.0K Nov  4 21:32 manager

这是我在manager 和404 错误中看到的内容。

任何帮助将不胜感激！

ps：我也从 docker 运行 Oracle，因为我的 webapp 使用它： docker run --name OracleXE --shm-size=1g -p 1521:1521 -p 8080:8080 -v /Users/laura/Desktop/data:/u01/app/oracle/oradata -e ORACLE_ALLOW_REMOTE=true oracle/database :11.2.0.2-xe

【问题讨论】：

  • 也许问题出在词汇表应用程序本身？
  • 我猜你的词汇表应用程序有问题。它有根映射吗？我建议您从 apache 下载示例 war 并在您的 tomcat 实例中试用 tomcat.apache.org/tomcat-8.0-doc/appdev/sample
  • 感谢您的帮助。我在本地有 Tomcat，并且能够很好地运行我的应用程序。正是在通过 docker 使用它时，我遇到了问题。我可以通过 docker 运行示例应用程序而不会出现任何错误。尝试通过 docker 运行我的应用程序时，我唯一要更改的是数据库连接字符串（因为我的应用程序使用来自另一个容器的 oracle），我将其更新到我的 ip（而不是本地主机）。 [forums.docker.com/t/…...

标签： java oracle tomcat docker


【解决方案1】：

好吧，既然您可以访问您的 tomcat 实例和管理器应用程序，那么您应该能够看到部署了哪些应用程序、它们是否正在运行以及它们的上下文路径。 那么词汇表是怎么说的呢？您是否有使用应用程序上下文路径 /glossary 部署和运行的应用程序？ 您可以通过访问 Tomcat Manager App 来回答这些问题

http://localhost:8080/manager/html（或您的特定主机和端口）

希望这会有所帮助！

您可以尝试的另一件事是将glossary.war 重命名为ROOT.war。这会将您的词汇表应用程序部署为 ROOT 应用程序，并且可以在 localhost:8080 下直接访问它（或您运行 tomcat 的任何端口）。

【讨论】：

  • 谢谢约丹。我添加了我在 Manager App 上看到的屏幕截图。我可以看到我的应用，但尝试访问 /glossary 时会出现 404。
  • 它表示您的应用程序已部署并正在运行。所以它必须是应用程序。由于我在那里没有看到名称，我会更仔细地查看 web.xml 包含的内容，并将默认的 index.html 文件放在应用程序。
