解释说明

• maven-dependency-plugin 打出项目依赖的第三方包，放在lib下面
• spring-boot-maven-plugin springboot打包插件，只保留了项目运行的jar包
• resources 排除了我们需要外置的文件

运行方式

将target下lib包和test.jar(运行包)以及src/main/resources下你需要外置的文件部署至服务器同一目录下，如

• lib
• test.jar
• *.yml
• *.xml
• *.properties
• static
• templates

最终运行

java -jar -Dloader.path=.,lib test.jar

完美运行，觉得不错的，点赞一波，收藏一波吧
