问题
springboot项目在使用压缩软件修改依赖包配置项后，启动报错，报错内容如下
Caused by: java.io.IOException: Unable to open nested jar file 'BOOT-INF/lib/bps-basic-properties-0.0.1-SNAPSHOT.jar'

原因：
替换或者导入jar包时，jar包被自动压缩，springboot规定嵌套的jar包不能在被压缩的情况下存储。
解决办法
使用jar命令解压jar包，在压缩包外重新替换jar包，在进行压缩。
- 解压jar包 jar -xvf *.jar
[yepikai@vyz-xiangcheng4 jars]$ jar -xvf material-center.jar
created: META-INF/
inflated: META-INF/MANIFEST.MF

- 替换jar包
或者先用软件替换，不用再替换，我这里是7z替换好后解压的。
// 先删除再新增
rm -rf BOOT-INF/lib/xxx.jar
mv xxx.jar BOOT-INF/lib/
- 重新压缩jar
jar -cfM0 name.jar BOOT-INF/ META-INF/ org/
