springBoot项目替换lib下的依赖jar包 Unable to open nested entry 'BO

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.jarException in thread "main" java.lang.IllegalStateException: Failed to get nested archive for entry BOOT-INF/lib/ojdbc7-12.1.0.2.0.jar        at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchive(JarFileArchive.java:109)        at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchives(JarFileArchive.java:87)        at org.springframework.boot.loader.ExecutableArchiveLauncher.getClassPathArchives(ExecutableArchiveLauncher.java:72)        at org.springframework.boot.loader.Launcher.launch(Launcher.java:49)        at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:51)Caused by: java.io.IOException: Unable to open nested jar file 'BOOT-INF/lib/ojdbc7-12.1.0.2.0.jar'        at org.springframework.boot.loader.jar.JarFile.getNestedJarFile(JarFile.java:252)        at org.springframework.boot.loader.jar.JarFile.getNestedJarFile(JarFile.java:237)        at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchive(JarFileArchive.java:104)        ... 4 moreCaused by: java.lang.IllegalStateException: Unable to open nested entry 'BOOT-INF/lib/ojdbc7-12.1.0.2.0.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/
