Maven缺少依赖：java.lang.ClassNotFoundException: org.apache.poi.openxml4j.exceptions.InvalidFormatExcepti

本文主要是介绍Maven缺少依赖：java.lang.ClassNotFoundException: org.apache.poi.openxml4j.exceptions.InvalidFormatExcepti，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.报错描述

运行IpHelper类的时候，报错：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/openxml4j/exceptions/InvalidFormatExceptionat com.ggstar.util.ip.IpHelper.getRegionRelationMap(IpHelper.java:88)at com.ggstar.util.ip.IpHelper.getIpRelation(IpHelper.java:58)at com.ggstar.util.ip.IpHelper.buildTrain(IpHelper.java:33)at com.ggstar.util.ip.IpHelper.<clinit>(IpHelper.java:27)at _1005SparkSQLproject.Log.IpUtils$.getCity(IpUtils.scala:12)at _1005SparkSQLproject.Log.IpUtils$.main(IpUtils.scala:16)at _1005SparkSQLproject.Log.IpUtils.main(IpUtils.scala)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:498)at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147)

2.原因

缺少pom依赖。

 

3.添加对应依赖

        <dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.14</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.14</version></dependency>
