使用 maven 同时启动两个 Spring Boot 应用程序

Question

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 中为application.properties，另一个在src/test/resources 中为test.properties。

我想要它，以便当我在 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，也许以编程方式？

Spring Boot 应用程序在 localhost 上运行，但有两个不同的端口。

主要的一个在localhost:28433 上运行，另一个在localhost:9119 上运行。

我试过运行这个 mvn 命令：

mvn spring-boot:run -Drun.arguments="--server.port=9119""--server.port=28433"

我不确定这是否有效.. 当我在终端中运行它时，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，所以我认为它没有做我想做的事......

如何同时启动这些？

Answer 1

我不知道 mockServerApp 的用途，但我认为 bootRun 不能处理多个应用程序，甚至不会扫描您的测试类。

如果您想模拟外部依赖项以进行单元测试，您应该将调用包装在某种代理类中并使用@MockBean 注入模拟实例。

如果您想为开发目的部署存根外部依赖项，您可以为存根创建一个单独的项目作为父目录，该目录将在启动时调用 maven。您甚至可以在不同的框架或语言中实现模拟。

最直接的选择是编写一个launches and kills both services 的shell 脚本。

为了指定端口，在每个的 application.properties 中将 server.port 设置为环境变量：

主应用程序.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
