编译打包之后为：

拆包实现

引入pom.xml依赖 & 新建assembly.xml

关键点为：

maven-shade-plugin中的<include>com.changlu:knowledge-*</include>，表示对应的com.changlu 指的是groupId，后缀knowledge-*指的是artifactId。
maven-jar-plugin中的指定启动器类：<mainClass>com.dtstack.knowledge.ai.server.KnowLedgeServerApplication</mainClass>
maven-antrun-plugin中指定了拷贝路径。

执行打包命令与测试

输出的打包后文件目录为，实现了拆包效果：

执行的命令为：

本机：

/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home/bin/java -cp "/Users/edy/changlu_workspace/daishuyun/材料/2025/2025.6.1黑客马拉松/code/knowledge-ai-chat/knowledge-ai-server/target/dtstack-platform/dtstack-platform/dtstack/:/Users/edy/changlu_workspace/daishuyun/材料/2025/2025.6.1黑客马拉松/code/knowledge-ai-chat/knowledge-ai-server/target/dtstack-platform/dtstack-platform/lib/" com.dtstack.knowledge.ai.server.KnowLedgeServerApplication

服务器：

shell 复制代码

# -cp 指定目录加载，这里指定两个位置：
#  /opt/tools/ai-chat/knowledge-server/lib/*、
/opt/tools/ai-chat/jdk/jdk-17.0.10+7/bin/java 、/opt/tools/ai-chat/knowledge-server/dtstack/* 
-cp /opt/tools/ai-chat/knowledge-server/lib/*:/opt/tools/ai-chat/knowledge-server/dtstack/* com.dtstack.knowledge.ai.server.KnowLedgeServerApplication

说明：后续真实项目的执行，后使用shell脚本形式来完成启动和关闭。
