- pom.xml: - 添加finalName配置去除版本号 - maven-jar-plugin排除资源文件 - 禁用spring-boot-maven-plugin repackage - 各服务移除冗余的plugin配置 - assembly.xml: - 主JAR放根目录（仅服务代码） - lib目录放依赖JAR - start.sh: - 支持java -cp classpath模式启动 - 从service.properties读取MAIN_CLASS - 向后兼容fat jar模式 - service.properties: - 所有服务添加MAIN_CLASS配置 优势: - 主JAR从131MB缩小到103KB - 多服务部署可共享lib目录 - 资源文件外置便于修改
