脑洞的由来
场景一:微服务部署,每个微服的包体都几十M,而且每个微服包体之间都有大量重复jar包
功能需求
比如当前项目是lp-spring-web,打包出来的包体是lp-spring-web.jar
- lp-spring-web.jar 只包含项目的字节码文件,也就只有class文件,而没有lib文件
- lp-sping-web项目依赖的jar包需要一份完整copy在lp-spring-web.jar外

执行 mvn package 后


我们打开lib文件夹就会看到相关依赖的jar包都在里面

测试
我们写一个bat来测试下是否成功
java -jar -Dloader.path=./target,./target/lib ./target/lp-spring-web-0.0.1-SNAPSHOT.jar
PS: 路径可自行修改

运行run.bat 后就会看到项目已正常启动
