我收到这个例外


  线程“主”中的异常java.lang.NoClassDefFoundError:
  org / apache / xmlbeans / XmlException在
  com.restcalls.JSONtoCSV.main(JSONtoCSV.java:176)


当我尝试将csv文件转换为excel文件时。
此行似乎是引起问题的原因-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");

最佳答案

您需要下载XML Bean依赖性并将其添加到类路径。该库通常称为xmlbeans-x.x.x.jar。例如:搜索并下载xmlbeans-2.6.0.jar,或者如果您具有如下所示的Maven项目设置POM

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