How a build library jar of spring boot application using maven
问题
我有一个名为A的应用程序，其中包含从数据库获取记录的代码和一些其他功能。我想在另一个名为B的项目中使用相同的代码，并将A用作依赖。尽管不推荐将Spring Boot应用程序用作库，但我有这个用例，因为应用程序A是批处理应用程序，不会持续运行，因此没有REST调用的选项。
问题在于，当我尝试创建jar文件时，它会被创建为Spring Boot的jar文件，或者如果我创建普通jar文件，则没有必需的依赖项，导致在运行时失败，因为找不到类。
似乎在创建jar文件时未包括来自A的父项目的依赖项。
是否有一种推荐的使用Maven生成jar文件的方法。
英文:
I have an application A which contains code to fetch records from dB and some other functionality. I want to use the same in another project B and use A as dependency. Even if spring boot apps are not recommended to be used as library I have this use case bcs app A is a batch application and doesn’t keep running so no option of rest call.
Issue is when I try to create the jar it is created as spring boot jar or if I create a normal jar it doesn’t have the required dependencies and fails at runtime as class not found.
It seems dependencies from parent project of A are not included during jar creation.
Is there a recommenced way of generating the jar using maven.

为了详细说明chrylis所说的：
创建一个项目或模块C，其中包含A和B都需要的所有内容。在A和B中使用它作为依赖。
处理这个问题最简单的方法是创建一个多模块项目，包括A、B和C，但你也可以有三个单独的项目。
英文:
To elaborate on what chrylis said:
Create a project or module C that contains everything that both A and B need. Use it as dependency in A and B.
The easiest way to handle this is to have a multi-module-project with A, B and C, but you can also have three separate projects.
