无法访问 tomcat，war 文件在与 docker 集成时未部署
Unable to reach tomcat, war file not deployed while integrating with docker
War 文件使用 mvn clean install 成功生成，然后在 terminal.The 中尝试使用 docker compose up --build 登录终端显示有没有创建表并且无法使用邮递员正确到达端点，tomcat 处于无法访问状态，因为 war 文件部署不当。我需要一个解决方案来将数据库与服务器连接起来并到达端点。我没有找到任何有用的信息来解决这个问题 issue.Help 我要获得正确的部署。

在 Docker 合成文件中，为 tomcat 拉取的图像有不同的版本，仅支持特定的 java 版本。因此，要么更改支持 Java 版本 11（在 pom 文件中）的 tomcat 图像版本文件，要么更改 Java 版本，如下所述：
在属性下的 POM 文件中做这样的更改 -
<properties>
<java.version>1.8</java.version>
</properties>
Error shown in terminal logs is tough to debug as it does not show any error at all instead of it, it completely ignores the artifactId
if it can't be deployed.
备注
我们需要确保三件事...
War 应复制到 tomcat 内的正确目录，如 -
(/usr/local/tomcat/webapps).
确保您的 java 版本与您的 tomcat 图像匹配
使用.
确保您的 sprint 启动应用程序 class 是正确的并且有
实施 SpringBootServletInitializer
After doing above mentioned changes, project will get deployed
successfully, will get connected to database & will access endpoints
as well.
War 文件使用 mvn clean install 成功生成，然后在 terminal.The 中尝试使用 docker compose up --build 登录终端显示有没有创建表并且无法使用邮递员正确到达端点，tomcat 处于无法访问状态，因为 war 文件部署不当。我需要一个解决方案来将数据库与服务器连接起来并到达端点。我没有找到任何有用的信息来解决这个问题 issue.Help 我要获得正确的部署。

虽然调试 tomcat 容器日志没有显示任何错误，说明到达 tomcat server.So 的问题，但很难调试。

在 Docker 合成文件中，为 tomcat 拉取的图像有不同的版本，仅支持特定的 java 版本。因此，要么更改支持 Java 版本 11（在 pom 文件中）的 tomcat 图像版本文件，要么更改 Java 版本，如下所述：
在属性下的 POM 文件中做这样的更改 -
<properties>
<java.version>1.8</java.version>
</properties>
Error shown in terminal logs is tough to debug as it does not show any error at all instead of it, it completely ignores the artifactId if it can't be deployed.
备注
我们需要确保三件事...
War 应复制到 tomcat 内的正确目录，如 - (/usr/local/tomcat/webapps).
确保您的 java 版本与您的 tomcat 图像匹配 使用.
确保您的 sprint 启动应用程序 class 是正确的并且有 实施 SpringBootServletInitializer
After doing above mentioned changes, project will get deployed successfully, will get connected to database & will access endpoints as well.
