使用POI导出excel时报错，发现到不了工具类中

SEVERE: Servlet.service() for servlet [springMvc] in context with path [/mjj_poi_two] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: org/apache/poi/ss/usermodel/RichTextString] with root cause
错误如上

我的jdk1.1
poi的jar包3.10
框架是ssi

很明显是因为依赖包的版本不对应的原因，导致class没有找到，建议你用较新的jar包进行编译

希望能够帮到你
