我得到了这个例外

线程中的异常＆＃34; main＆＃34; java.lang.NoClassDefFoundError： org / apache / xmlbeans / XmlException at com.restcalls.JSONtoCSV.main（JSONtoCSV.java:176）

当我试图将csv文件转换为excel文件时。这一行似乎导致了问题 - XSSFWorkbook workBook = new XSSFWorkbook();。

我已经添加了最新的POI jar - 3.17，这是我的代码：

String xlsxFileAddress = "C:/Users/xxxxx/REST/exports/test.xlsx"; //xlsx file address
System.out.println("here 0");
XSSFWorkbook workBook = new XSSFWorkbook();
System.out.println("here 0.1");
XSSFSheet sheet =  workBook.createSheet("sheet1");
System.out.println("here 1");
String currentLine=null;
int RowNum=0;
BufferedReader br = new BufferedReader(new FileReader(csvFileAddress));
System.out.println("here 2: "+br);
while ((currentLine = br.readLine()) != null) {
    String str[] = currentLine.split(",");
    RowNum++;
    XSSFRow currentRow=sheet.createRow(RowNum);
    for(int i=0;i<str.length;i++){
        currentRow.createCell(i).setCellValue(str[i]);
    }
}

FileOutputStream fileOutputStream =  new FileOutputStream(xlsxFileAddress);
workBook.write(fileOutputStream);
fileOutputStream.close();
System.out.println("Done");

您需要下载并将XML bean依赖项添加到类路径中。该库通常称为xmlbeans-x.x.x.jar。例如：搜索并下载xmlbeans-2.6.0.jar，或者如果你有一个maven项目设置POM如下

  <dependency>
    <groupId>org.apache.xmlbeans</groupId>
    <artifactId>xmlbeans</artifactId>
    <version>2.6.0</version>
  </dependency>

从csv转换为excel时出现NoClassDefFoundError
