有时候构建一个多模块maven项目其中某一个模块是web-service需要使用spring boot,其他模块跟spring boot 完全无关,本文总结一下在这个场景下maven项目最佳构建方式.
一般的实现
网上应该也看到过很多人写的文章,思路非常简单,即是将整个项目作为spring-boot-starter-parent 的子项目. 这样整个项目里面所有模块都可以在dependencies里面添加上有parent内指定版本的spring boot 相关的起步依赖包. 而不需要使用spring的模块可以完全不用管这个parent pom.
比如要构建如下含有三个模块的maven project:
module namedescriptioncore存放一些公共的类的模块,可被其他模块使用web-servicespring boot service 对外提供rest apispark-jobspark 项目
project的pom.xml如下:

使用spring-boot-dependencies 更优雅的实现.
spring 本身提供了这样一个pom 来管理所有依赖: https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies 且官方也给了怎么使用这个pom的方法
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-dependencies/artifactIdversion2.7.18/versiontypepom/typescopeimport/scope
/dependency有了这个pom引入到项目里面,就可以不用将spring-boot-starter-parent作为整个项目的parent. 改造一下项目的pom
