文件索引：
1 TestExport.java 主程序
2 student.java 数据bean
3 template.xls 模板文件

以下为例子程序：
TestExport.java

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import net.sf.jxls.transformer.XLSTransformer;
import org.apache.poi.ss.usermodel.Workbook;

public class TestExport {

    public void export() {
        List<Student> studentList = new ArrayList<Student>();
       
        Student studentA = new Student();
        studentA.setName("tom");
        studentA.setAge(20);
        Student studentB = new Student();
        studentB.setName("John");
        studentB.setAge(21);
       
        studentList.add(studentA);
        studentList.add(studentB);
       
        Map beans = new HashMap();
        beans.put("studentList", studentList);
        XLSTransformer transformer = new XLSTransformer();
        try {
            InputStream xlsTemplateIO = new BufferedInputStream(new FileInputStream("./template.xls"));
            Workbook book = transformer.transformXLS(xlsTemplateIO, beans);
            OutputStream os = new FileOutputStream("./abc.xls");
            book.write(os);
            os.flush();
            os.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Student.java

    private String name;
    private Integer age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}
