我有两个带有自己的 application.properties 的 spring boot 应用程序。
一个在我的 src/main/resources 中作为 application.properties 另一个在 src/中作为 。 test.properties测试/资源
我想要这样当我在 main 中启动我的 spring boot 应用程序时，它也会同时在我的测试中启动 spring boot 应用程序。我想在 Maven 命令行中执行此操作，但我也想知道是否也可以在 Spring Boot 中执行此操作，也许是通过编程方式？
spring boot 应用程序在 localhost 但两个不同的端口上运行。
main 中的一个在 localhost:28433 上运行，另一个在 localhost:9119 上运行。
我已经尝试运行这个mvn 命令:
mvn spring-boot:run -Drun.arguments="--server.port=9119""--server.port=28433"
不过我不确定这是否有效。当我在我的终端中运行它时，它会输出:

上面说它正在使用 127.0.0.1:9119 但它似乎只启动了我的主应用程序而不是我的测试应用程序，它专门称为 mockServerApp 所以我不要以为它在做我想做的...
如何同时启动这些？
最佳答案
我不知道 mockServerApp 的用途是什么，但我认为 bootRun 不会处理多个应用程序，甚至不会扫描您的测试类。
如果你想模拟一个外部依赖用于单元测试，你应该将调用包装在某种代理类中并使用@MockBean 来注入(inject)一个模拟实例。
如果您想为开发目的部署 stub 外部依赖项，您可以为 stub 创建一个单独的项目作为父目录，在启动时调用 maven。您甚至可以使用不同的框架或语言来实现模拟。
最直接的选择是编写一个 shell 脚本 launches and kills both services .
为了指定端口，在每个的application.properties中设置server.port为环境变量:
主要应用程序.conf:
server.port=${MY_APP_PORT:28433}
模拟应用程序.conf:
server.port=${MOCK_APP_PORT:9119}
要在集成测试中启动外部依赖项，请查看 Testcontainers
