从单个 Maven 项目运行多个 SpringBootApplication 类 [英] Running multiple SpringBootApplication classes from a single maven project

问题描述

有没有办法指定运行mvn spring-boot:run时运行哪个SpringBootApplication的主类?文档 说我可以使用 mainClass 参数来指定要运行的主类.但我不确定如何在命令行中指定它.我试过 mvn -DmainClass=mypackage.myclass spring-boot:run 但没有用.

Is there a way to specify which SpringBootApplication's main class to run when running mvn spring-boot:run? The docs say I can use mainClass parameter to specify which main class to run. But I am not sure how to specify it in command line. I have tried mvn -DmainClass=mypackage.myclass spring-boot:run but it didn't work.

推荐答案

我通过在 spring-boot 的插件配置中使用占位符使其工作

I got it working by having a placeholder in the plugin configuration of spring-boot

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>${mainclass}</mainClass>
            </configuration>
        </plugin>

然后运行不同的类

mvn -Dmainclass=mypackage.myclass spring-boot:run
