的Java读取Excel文件

Question

我相信我有我需要的所有jar文件，我仍然收到这个说由导致错误：

java.lang.reflect.InvocationTargetException

原谅我，我在阅读错误信息方面仍然不太好。该错误提示的问题是与线"Workbook book = new XSSFWorkbook(stream);"

import java.io.File; 
    import java.io.FileInputStream; 
    import java.io.IOException; 
    import java.util.Iterator; 

    import org.apache.poi.ss.usermodel.Cell; 
    import org.apache.poi.ss.usermodel.Row; 
    import org.apache.poi.ss.usermodel.Sheet; 
    import org.apache.poi.ss.usermodel.Workbook; 
    import org.apache.poi.xssf.usermodel.XSSFWorkbook; 

    public class excelReader { 
public static void main(String[] args) throws IOException{ 

    String spreadSheetFilePath = "C:\\Users\\userExample\\Documents\\forJava.xlsx"; 
    FileInputStream stream = new FileInputStream(new File(spreadSheetFilePath)); 

    Workbook book = new XSSFWorkbook(stream); 
    Sheet sheetOne = book.getSheetAt(0); 
    Iterator<Row> iterator = sheetOne.iterator(); 

    while(iterator.hasNext()) { 
     Row nextRow = iterator.next(); 
     Iterator<Cell> cellIter = nextRow.cellIterator(); 

     while(cellIter.hasNext()) { 
     Cell cell = cellIter.next(); 

     switch (cell.getCellType()) { 
     case Cell.CELL_TYPE_STRING: 
      System.out.print(cell.getStringCellValue()); 
      break; 
     case Cell.CELL_TYPE_BOOLEAN: 
      System.out.print(cell.getBooleanCellValue()); 
      break; 
     case Cell.CELL_TYPE_NUMERIC: 
      System.out.print(cell.getNumericCellValue()); 
      break; 
     } 
     System.out.print(" - "); 
     } 
     System.out.println(); 
    } 
    book.close(); 
    stream.close(); 
} 

}

错误我得到

如果你看一下堆栈跟踪，你可以发现异常的原因是：

java.lang.NoSuchMethodError: org.apache.xmlbeans.XmlOptions.setLoadEntityBytesLimit(I)Lorg/apache/xmlbeans/XmlOptions; 

基于该我认为你需要的：的xmlbeans-xmlpublic-2.6.0.jar类路径中，尝试这种额外的jar添加到类路径，然后再试一次......

我建议管理使用Maven的依赖，这将简化一切，只需切换到Maven和添加以下行到你的POM文件：

<dependency> 
    <groupId>org.apache.poi</groupId> 
    <artifactId>poi</artifactId> 
    <version>3.14</version> 
</dependency> 
<dependency> 
    <groupId>org.apache.poi</groupId> 
    <artifactId>poi-ooxml</artifactId> 
    <version>3.14</version> 
</dependency>
