一、该问题的重现步骤是什么？
1. 从私服下载bladex-boot，解包到一个目录bladex-boot
2. 从私服下载saber，解包到一个目录saber
3.在saber目录下运行npm run install、npm run serve，启动客户端
4.打开IDEA，打开bladeX-boot项目，在my sql里执行建库脚本，创建bladex数据库
5. 修改pom.xml为如下内容：主要是改动build部分，目标是把所有外部公共jar包放入target\lib目录，应用单独打包为bladeX.jar
附件为修改了的pom.xml
6. 命令行执行mvn clean package，显示打包成功,生成了BladeX.jar，以及所有外部依赖都拷贝到了target\lib目录，相关资源拷贝到Resource目录
7. 启动应用服务：java -jar BladeX.jar -Dloader.path=.\lib，控制台显示成功：

二、环境：
OS：windows 10 pro， mysql 6.5
三、项目pom按官方默认打包执行没有任何问题，我只是想以后开发时老是打个大肥包，不大适合模块分工开发，所以希望把公共jar包提取到一个公共目录，每个模块成员只更新公共jar包外的代码。
SpringBoot+Mybatisplus CRUD项目，用2种打包方式，验证都正常
springboot_mybatisplus_demo-分离lib打包.rar
springboot_mybatisplus_demo.rar
步骤：
1、先测试正常打包方式，将springboot_mybatisplus_demo.rar解压到一个目录
2、在mysql里建库，名称：springboot_mybatisplus_demo
3、执行doc目录下的sql脚本，建表和测试数据
4、在项目目录下进入到cmd命令行，执行：mvn package
5、cmd命令行执行：cd target，
6、cmd命令行执行：java -jar sbmp-demo.jar
7、chrome浏览器输入：localhost:8080/swagger-ui.html,进入api交互界面
8、点UserController链接，再点 /user/addUser
9、在展开的界面里输入如下参数：再点Try it out
10、后台返回如下：
11、测试查询，下滚到 GET /user/getUserListLikeName，点击
/user/getUserListLikeName，输入如下参数：
点击Try it out! 得到如下结果，可以看到刚才增加的数据已经成功：
二、测试分离lib和资源方式打包
0、退出和关闭上面启动后台java程序命令行窗口；
1、把springboot_mybatisplus_demo-分离lib打包.rar解压到另外一个目录下
2、进入到该项目目录，进入到命令行
3、执行mvn clean package
4、进入到target目录，可以看到比上面一种打包方式多了lib和resource目录
5、执行java -jar sbmp-demo.jar -Dloader.path=./lib
6、在浏览器另外开一个页面，输入localhost:8080/swagger-ui.html
7、按上面打包方式的步骤8-11测试，一样的结果，都成功了。
