如何使用嵌入式服务器运行 Jakarta EE 应用程序？

问题描述 投票：0回答：1

我的目标是创建使用嵌入式 Web 服务器和嵌入式数据库的 Jakarta EE Web 应用程序，因此可以使用单个命令运行此 Web 应用程序。

目前我有一个使用嵌入式 H2 数据库的应用程序，它在部署到单独的 Glassfish 实例时工作正常，但在嵌入数据库时失败。

我已经尝试了

cargo-maven3-plugin
和
wildfly-maven-plugin
。

示例项目

这是我尝试在嵌入式 Jakarta EE 服务器中启动的 Web 应用程序：

期望

我期望执行

mvn clean package cargo:run
或
mvn clean package wildfly:dev
，并且其余端点将变得可用：
curl.exe -X GET http://localhost:8080/myapp/rest/person/all/

现实

mvn clean package cargo:run
结果是这个堆栈跟踪：

并且 

mvn clean package wildfly:dev

提供的示例应用程序可以使用此单个命令运行：

mvn clean package org.codehaus.cargo:cargo-maven3-plugin:run -Dcargo.maven.containerId=glassfish7x

除了 

pom.xml
和 
maven-compiler-plugin
之外，所有来自 
maven-war-plugin
的插件都可以删除。无需额外配置。

控制台会出现消息：

[INFO] [talledLocalContainer] GlassFish 7.0.6 started on port [8080]
[INFO] Press Ctrl-C to stop the container...

但是按 Ctrl-C 可能会导致停止容器的尝试失败 - 您必须手动终止 java 进程。

要更正确地停止容器，请首先向服务器发送网络请求：

curl.exe -X GET http://localhost:4848/__asadmin/stop-domain -u admin:adminadmin

按下Ctrl+C后，所有资源将被释放，容器将正常停止。

Codehaus Cargo Maven 3 插件中提供的其他容器和用例可以在这里找到： https://codehaus-cargo.github.io/cargo/Maven+3+Plugin.html
