我想使用此代码将Excel数据插入数据库 .
public class Insert {
public static void main( String [] args ) {
String fileName="C:\\File.xls";
Vector dataHolder=read(fileName);
saveToDatabase(dataHolder);
}
public static Vector read(String fileName) {
Vector cellVectorHolder = new Vector();
try{
FileInputStream myInput = new FileInputStream(fileName);
POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput);
HSSFWorkbook myWorkBook = new HSSFWorkbook(myFileSystem);
HSSFSheet mySheet = myWorkBook.getSheetAt(0);
Iterator rowIter = mySheet.rowIterator();
while(rowIter.hasNext()){
HSSFRow myRow = (HSSFRow) rowIter.next();
Iterator cellIter = myRow.cellIterator();
Vector cellStoreVector=new Vector();
while(cellIter.hasNext()){
HSSFCell myCell = (HSSFCell) cellIter.next();
cellStoreVector.addElement(myCell);
}
cellVectorHolder.addElement(cellStoreVector);
}
}catch (Exception e){e.printStackTrace(); }
return cellVectorHolder;
}
private static void saveToDatabase(Vector dataHolder) {
String username="";
String password="";
for (int i=0;i<dataHolder.size(); i++){
Vector cellStoreVector=(Vector)dataHolder.elementAt(i);
for (int j=0; j < cellStoreVector.size();j++){
HSSFCell myCell = (HSSFCell)cellStoreVector.elementAt(j);
String st = myCell.toString();
username=st.substring(0,1);
password=st.substring(0);
}
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root", "root");
Statement stat=con.createStatement();
int k=stat.executeUpdate("insert into login(username,password) value('"+username+"','"+password+"')");
System.out.println("Data is inserted");
stat.close();
con.close();
}
catch(Exception e){}
}
}
}
如何在按钮中插入此代码？

通常，您必须向按钮添加Action侦听器：
