现在的开发一直都是用spring boot突然有一天要自己开发一个没有springboot的程序才想起mvn package都快遗忘了。主要存在两个问题 打包的程序没有main入口。 打包的程序没有包含依赖。
二、解决方法
这里有两种方法
1方法一、maven-jar-pluginmaven-dependency-plugin
这种方法最后生成的jar包不会把依赖放到jar里只是会把/lib放到跟jar一个目录。看下图
maven-jar-plugin 负责打jar包写main入口maven-dependency-plugin 负责找出依赖把所有依赖copy到lib目录中。
优点发布新程序的时候-速度快。缺点第一次依赖lib要自己copy
源代码我就不多讲解了。这里贴出我的pom.xml

/project2方法二、maven-assembly-plugin
这种方法是把lib打到jar中的方法
先上代码

/project最后看一下生成的文件 明显比刚才大了很多。
