记一次IDEA 打包环境JDK版本和生产环境JDK版本不一致引发的血案

问题描述：

本地开发环境idea中能正常运行项目，而idea打war包到Linux服务器的Tomcat下却不能正常运行，报如下错误：

09-Aug-2019 08:56:06.878 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file

问题排查：

IDEA 打包环境JDK版本和Linux生产环境JDK版本不一致,导致线上Tomcat无法正常运行

解决方案：

• 1、确保两边环境安装相同的jdk版本
• 2、选择idea导航栏中Help -》Find Action，在弹框中输入Switch Boot JDK，在select Boot JDK中选择本机jdk版本，然后重启，在idea的Terminal运行java -version命令确认：
  
• 3、打包后检查war包内META-INF下的MANIFEST.MF文件,查看编译环境,确保jdk版本（get以下META-INF的作用）:

    Manifest-Version: 1.0
    Built-By: Administrator
    Created-By: Apache Maven 3.5.0
    Build-Jdk: 1.8.0_161
