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: tmp> 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: tmp> 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/
