java.lang.ClassNotFoundException가 : org.apache.poi.ss.formula.udf.IndexedUDFFinder

Question

I가 실행 : 나는 이러한 패키지를 가져온

java.lang.ClassNotFoundException: org.apache.poi.ss.formula.udf.IndexedUDFFinder 

:

Workbook workbook = new XSSFWorkbook([from a FileInputStream]); 

나는 오류를 얻을 :

import org.apache.poi.ss.usermodel.Workbook; 
import org.apache.poi.xssf.usermodel.XSSFWorkbook; 

그들은이 같은 메이븐의 pom.xml에 따라 달라집니다

<dependency> 
    <groupId>org.apache.poi</groupId> 
    <artifactId>poi-ooxml</artifactId> 
    <version>3.10-FINAL</version> 
</dependency> 

Answer 1

poi (3.9)와 poi-ooxml (3.10)의 버전 차이로 인해이 오류가 발생했습니다. 버전을 확인하십시오. 나를 위해 올바른 하나

<dependency> 
     <groupId>org.apache.poi</groupId> 
     <artifactId>poi</artifactId> 
     <version>3.10-FINAL</version> 
     <type>jar</type> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.poi</groupId> 
     <artifactId>poi-ooxml</artifactId> 
     <version>3.10-FINAL</version> 
     <type>jar</type> 
    </dependency> 

Answer 2

내가 사용하고는 다음과 잘 작동합니다 :

import org.apache.poi.xssf.usermodel.XSSFCell; 
import org.apache.poi.xssf.usermodel.XSSFRow; 
import org.apache.poi.xssf.usermodel.XSSFSheet; 
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

InputStream myxls = new FileInputStream(fileName); 
XSSFWorkbook wb = new XSSFWorkbook(myxls);

     <groupId>org.apache.poi</groupId> 
     <artifactId>poi</artifactId> 
     <version>3.15</version>
