Maven多模块项目-从另一个模块启动模块？

Question

我是一名新手，也许有人可以帮忙。

是否可以从另一个模块启动模块？

例如：

我的模块：F-前端，B-后端

现在，我通过码头启动前端模块，但是我需要后端功能，并且也需要运行后端模块。

可能吗？ 有任何想法吗？

非常感谢

PS。 我正在使用intelliJ

更新2在mvn部署后端之后。

Answer 1

Maven模块不是单独的应用程序。 不同的模块可用于将应用程序的不同部分指定为不同的Jar，以实现可重用性。
您真正开始的是一个应用程序（或战争等）。 通过导入该jar，项目可以链接到子模块的位置。

父pom需要调用要构建的模块（并且需要用完父对象的pom.xml位置：

<modules>
    <module>front-end</module>
    <module>back-end</module>
</modules>

那么，您是说通过pom.xml导入其他jar吗？
