Question

我使用apache poi完成了excel表的读写。但是如果我试图使用相同的apache poi下载ms-word，它会抛出错误。 java.lang.IllegalAccessError：尝试从类org.apache.poi.openxml4j.opc.ZipPackage

访问方法org.apache.poi.util.POILogger.log（ILjava / lang / Object;）

     <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>

     </dependency>

esp.setContentType（ “应用程序/ msword”）;

    resp.setHeader("Content-Disposition", "attachment;filename=\"" + "xx.docx" + "\"");

    XWPFDocument document= new XWPFDocument();
    XWPFParagraph paragraph = document.createParagraph();

    paragraph.setAlignment(ParagraphAlignment.CENTER);
    XWPFRun run=paragraph.createRun();

    run.setText("The endeavour started by Mohtashim, an AMU " +
               "alumni, who is the founder and the managing director " +
               "of Tutorials Point (I) Pvt. Ltd. He came up with the " +
               "website tutorialspoint.com in year 2006 with the help" +
               "of handpicked freelancers, with an array of tutorials" +
               " for computer programming languages. ");

    OutputStream outputStream = resp.getOutputStream();
    PrintStream stream = new PrintStream(outputStream);
    document.write(stream);

请给我这个问题的解决方案

Answer 1

我使用他的maven依赖并编写我的测试代码

这是我的代码

import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.ParagraphAlignment;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class SampleWord {

    public static void main(String[] args) throws Exception{
        XWPFDocument document= new XWPFDocument();
        XWPFParagraph paragraph = document.createParagraph();

        paragraph.setAlignment(ParagraphAlignment.CENTER);
        XWPFRun run=paragraph.createRun();

        run.setText("The endeavour started by Mohtashim, an AMU " +
                   "alumni, who is the founder and the managing director " +
                   "of Tutorials Point (I) Pvt. Ltd. He came up with the " +
                   "website tutorialspoint.com in year 2006 with the help" +
                   "of handpicked freelancers, with an array of tutorials" +
                   " for computer programming languages. ");


        FileOutputStream fileOut = new FileOutputStream("/Users/chenpengye/Documents/excel/test/test.docx");


        document.write(fileOut);

        document.close();

    }

}

但是，没有出现任何错误;

请在同一个版本检查你的poi; 这是我的pom.xml

<!-- poi excel 2003 -->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.13</version>
    </dependency>
    <!-- poi excel 2007 -->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.13</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.12</version>
    </dependency>

请检查你的jar版本。我认为是jar版本冲突引起的这个错误，请保持poi，poi-ooxml，poi-ooxml-schemas，poi-scratchpad都有相同的版本。
