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

Question

我之前在跑步:

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

我收到错误:

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

我导入了这些包:

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

它们依赖于Maven pom.xml,如下所示:

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

Answer 1

由于poi(3.9)和poi-ooxml(3.10)之间的版本差异,我收到此错误.检查您的版本.对我来说是正确的:

<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>
