java开发怎么导入导出excel里面信息内容

前段时间正好做了，导入和导出的，你自己看吧

下面是我写的一个运用jxl生成Excel文件的方法

该方法接收一个保存MarkesData数据的ArrayList arlist和文件生成路径Path

通过取得arlist里的数据生成Excel文件

感觉应该是你想要的 我没调试过也许有错 你也可以根据你的需要进行修改^_^

import javaioFile;

import javaioIOException;

import javautilArrayList;

import javautilIterator;

import jxlWorkbook;

import jxlwriteLabel;

import jxlwriteWritableSheet;

import jxlwriteWritableWorkbook;

import jxlwriteWriteException;

import jxlwritebiffRowsExceededException;

public class WriteExcel {

WritableWorkbook book=null;

public void OutputExcel(ArrayList arlist,String Path){

try{

book = WorkbookcreateWorkbook(new File(Path));

//设置表名

WritableSheet sheet = bookcreateSheet("考试单",0);

//生成表格题头

Label labe1 = new Label(0, 0, "考生姓名" );

Label labe2 = new Label(1, 0, "地区");

Label labe3 = new Label(2, 0, "所属院校");

Label labe4 = new Label(3, 0, "班级");

Label labe5 = new Label(4, 0, "考试号");

Label labe6 = new Label(5, 0, "考试时间");

Label labe7 = new Label(6, 0, "科目名称");

//将生成的单元格添加到工作表中

sheetaddCell(labe1);

sheetaddCell(labe2);

sheetaddCell(labe3);

sheetaddCell(labe4);

sheetaddCell(labe5);

sheetaddCell(labe6);

sheetaddCell(labe7);

Iterator it = arlistiterator();

int i = 1;

while(ithasNext()){

//通过迭代获得arlist里的MarkesData对象

MarkesData temp = (MarkesData)itnext();

//取得数据生成单元格

Label label1=new Label(0,i,tempgetUser_name());

Label label2=new Label(1,i,tempgetArea_name());

Label label3=new Label(2,i,tempgetCollege_name());

Label label4=new Label(3,i,tempgetClass_name());

Label label5=new Label(4,i,tempgetTest_name());

Label label6=new Label(5,i,tempgetStarttime());

Label label7=new Label(6,i,tempgetSubject_name());

//将生成的单元格添加到工作表中

sheetaddCell(label1);

sheetaddCell(label2);

sheetaddCell(label3);

sheetaddCell(label4);

sheetaddCell(label5);

sheetaddCell(label6);

sheetaddCell(label7);

i++;

}

bookwrite();

bookclose();

} catch (RowsExceededException e) {

eprintStackTrace();

} catch (WriteException e) {

eprintStackTrace();

} catch (IOException e) {

eprintStackTrace();

} finally{

try{

if(book!=null)bookclose();

}catch(Exception e){

Systemoutprintln("exception when closing Connection in finally");

Systemoutprintln(egetMessage()toString());

}

}

}

}
