問題：
springboot項目在使用壓縮軟件替換lib下的依賴包後，啓動報錯，報錯內容如下：
PS D:\ttmp> java -jar .\epayBusiness-2.0.2-SNAPSHOT.jar

原因：
替換或者導入jar包時，jar包被自動壓縮，springboot規定嵌套的jar包不能在被壓縮的情況下存儲。
解決（本文以升級ojdbc包爲例）：
使用jar命令解壓jar包，在壓縮包外重新替換jar包，在進行壓縮。
步驟1：解壓jar包 jar -xvf *.jar
PS D:\ttmp> jar -xvf *.jar
已創建: META-INF/
已解壓: META-INF/MANIFEST.MF
已創建: BOOT-INF/
已創建: BOOT-INF/classes/
已創建: BOOT-INF/classes/com/
步驟2：替換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/
步驟3：重新壓縮jar
jar -cfM0 new.jar BOOT-INF/ META-INF/ org/
