在Linux系统中项目部署的时候，操作easyexcel生成excel报的错误

Servlet.service() for servlet [dispatcherServlet] inst processing failed; nested exception is com.alibaba.excel.exception.ExcelGenerateException: java.lang.InternalError: java.lang.reflect.InvocationTarge
java.lang.NullPointerException: null
 
这是引起的原因是Java 的jdk版本对当前的easyexcel不支持
我当时用的是jdk14
 
解决方案：
　　　1，降低jdk版本，建议jdk11
　　    
           2.我用java14跑项目，每次生成数据的时候都报错，后面我下Jdk8，用Jdk8跑项目，跑不了，我就把JAVA8给卸载了，在用jdk14去跑项目easyexcel就可以了生成excel
