springBoot项目替换lib下的依赖jar包 Unable to open nested entry 'BOOT-INF/lib/

问题：

springboot项目在使用压缩软件替换lib下的依赖包后，启动报错，报错内容如下：

PS D:\ttmp> java -jar .\epayBusiness-2.0.2-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（本文以升级ojdbc包为例）：

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。

步骤1：解压jar包   jar -xvf  *.jar

PS D:\ttmp> jar -xvf *.jar
  已创建: META-INF/
  已解压: META-INF/MANIFEST.MF
  已创建: BOOT-INF/
  已创建: BOOT-INF/classes/
  已创建: BOOT-INF/classes/com/

步骤2：替换jar包

rm -rf BOOT-INF/lib/ojdbc14-10.2.0.4.0.jar
mv ojdbc7-12.1.0.2.0.jar BOOT-INF/lib/

步骤3：重新压缩jar

 jar -cfM0 new.jar BOOT-INF/ META-INF/ org/
