In the open source world, there are two more influential API available, one is the POI, is a jExcelAPI. Wherein jxl function is relatively weak POI point. But jExcelAPI for Chinese support is very good, API is a pure Java, does not rely on Windows systems, even while running under Linux, it is also able to correctly handling Excel files. Also need to note it is that this API is very limited support for graphics and charts, but only identify the PNG format.
Built environment: the file after downloading unpack, get jxl.jar, into the classpath, the installation is complete.
Download jar package:

Basic operation:
1. Create excel, and write data
import java.io.File;
import jxl.Sheet;
import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

//第一行设置列名:创建数组

//设置列名
for (int i = 0; i < title.length; i++) {

//追加数据
for (int i = 1; i <=30; i++) {
label=new Label(0,i,"id"+i);
sheet.addCell(label);
label= new Label(1,i,"张"+i);
sheet.addCell(label);
label=new Label(2,i,"男");
sheet.addCell(label);
label=new Label(3,i,"18"+i);
sheet.addCell(label);

//写入数据
workbook.write();
workbook.close();

2. Read Excel file:
