包装弹簧子项目分成一个罐子 [英] Packaging spring sub-projects into one jar

问题描述

我正在使用基于Spring的网络应用程序，我正在尝试将其捆绑到一个jar中。

I'm having Spring based web-app that I'm trying to bundle into a single jar.

我对该项目进行布局的想法是包含多个子项目的根项目，其中有一个子项目是一个spring-boot应用程序，而其他子项目可能是我自己编写的代码处理某些业务逻辑。

My thoughts on laying out the project was to have a root project that contains multiple sub-projects, where there would be one sub-project that is a spring-boot application, and others sub-projects maybe my own-written code handle certain business logic let's say.

所以结构可能如下所示：

So the structure may look something like:

/root
 build.gradle <- the problem is here, how I should write root project build script
 /spring-backend-subproject
 /other-business-subproject

拥有所有这些子项目后，我想将它们全部打包成一个JAR，这样我才能做到

Having all these sub-projects, I want to package them all into one single JAR, so that I can just do

java -jar build/libs/RootJar.jar

否则我需要运行：

./gradlew bootRun

将运行spring-boot子项目中的特定主类

which will run the particular main class in the "spring-boot" sub-project

我一直在网上搜索如何将所有子项目罐子捆绑到一个罐子里，例如：可以Gradle将多个项目放到一个jar中吗？
但是我经常最终会遇到像main-class这样的错误（如果我在spring子项目文件夹中专门运行jar）或者找不到SpringApplication类（如果在子项目文件夹中运行jar，则不会发生）

I've been searching online for how to bundle all subproject jars into one jar, such as this one: Can Gradle jar multiple projects into one jar? but I often just end up having errors such as main-class not found(which does not happen if I run the jar specifically in the "spring sub-project" folder) or SpringApplication class not found (again does not happen if run jar in the sub-project folder)

我如何解决这个问题？

谢谢！

推荐答案

我广泛使用这种模式。而不是尝试将部署类放入根目录，添加一个模块（我通常称之为 -launcher ），将其他模块列为依赖项并包含您的主类和相关应用程序代码，例如您可能拥有的任何 application.properties 。

I use this pattern extensively. Instead of trying to put the deployment classes into the root, add a module (I usually call it -launcher) that lists the other modules as dependencies and contains your main class and related application code, such as any application.properties you may have.

此模块将生成工件 my-project-launcher.jar ，然后将其部署到您正在使用的任何平台上。

This module will produce an artifact my-project-launcher.jar, and you deploy this to whatever platform you're using.
