在Centos 6.4 / Open JDK 1.7.0上运行Spring Boot jar时出现java.io.IOException [英] java.io.IOException when running Spring Boot jar on Centos 6.4 / Open JDK 1.7.0

问题描述

我们有一个Spring Boot（0.5.0.M7）生成的jar文件。当我们 mvn clean package然后在Windows 7（带有Oracle 64位Java SE JVM的64位1.7.0_51-b13）上运行（ java -jar target / my-app-camel-0.1.0.jar）时），一切都按预期进行：

We have a spring boot (0.5.0.M7) generated jar file. When we "mvn clean package" and then run ("java -jar target/my-app-camel-0.1.0.jar") on Windows 7 (64 bit with Oracle 64-bit Java SE JVM, 1.7.0_51-b13) it all works as expected:

但是，当我们 mvn clean package和然后在CentOS 6.4版（最终版）（64位OS，带有OpenJDK 64位Java SE JVM 1.7.0_51-b02）上运行（ java -jar target / my-app-camel-0.1.0.jar）失败：

However, when we "mvn clean package" and then run ("java -jar target/my-app-camel-0.1.0.jar") on CentOS release 6.4 (Final) (64 bit OS, with OpenJDK 64-bit Java SE JVM, 1.7.0_51-b02) it fails:

java.io.IOException: Unable to find ZIP central directory records after reading 206 bytes

注意：当我在Centos命令行上解压缩my-app-camel.jar时，它将提取

NOTE: When I "unzip my-app-camel.jar" on the Centos command line it extracts fine.

推荐答案

好像是本地maven缓存中的错误JAR文件（发生）。值得尝试的一件事实际上是使用 mvn spring-boot：run运行应用程序。如果您的JAR文件不正确，则可能会以这种方式显示。另一个方法是删除本地缓存的文件（例如，从〜/ .m2 /存储库中删除）并重建应用程序。

Looks like it was a bad JAR file in the local maven cache (it happens). One thing that's worth trying is actually running the app with "mvn spring-boot:run". If you have a bad JAR file it might show up that way. Another is to delete the local cached file (e.g. from "~/.m2/repository") and rebuild the application.
