jasperreport.javabean.User.java

package jasperreport.javabean;

import java.util.Date;

public class User {
	private String username;
	private Date birthday;

	public User(String username, Date birthday) {
		this.username = username;
		this.birthday = birthday;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public Date getBirthday() {
		return birthday;
	}

	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}

}

 jasperreport.javabean.JasperReportWithJavaBean.java

package jasperreport.javabean;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import net.sf.jasperreports.engine.JRExporterParameter;

public class JasperReportWithJavaBean {
	public static void export() throws Exception{
		
		InputStream inputStream = JasperReportWithJavaBean.class.getResourceAsStream("JavaBeanReport.jasper");
		Map parameters = new HashMap();
		
		List users = new ArrayList();
		users.add(new User("user_01",new Date()));
		users.add(new User("user_02",new Date()));
		users.add(new User("user_03",new Date()));
		
		JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(users);
		JasperPrint jasperPrint = JasperFillManager.fillReport(inputStream, parameters, dataSource);
		
		
		JRTextExporter exporter = new JRTextExporter();
		
        exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);  
        exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "javabean.txt");  
        exporter.setParameter(JRTextExporterParameter.PAGE_WIDTH, 200);  
        exporter.setParameter(JRTextExporterParameter.PAGE_HEIGHT, 100);  
		exporter.exportReport();
	}
	
	public static void main(String[] args) throws Exception{
		export();
	}
}
