JasperReport+Struts2学习记录

一、步骤
（1）将struts2的jasperreport插件包和jasperreport包导入，struts2项目中
（2）编写action

import java.util.ArrayList;
import java.util.List;

import smartcoms.web.UIElement.Account;

import com.opensymphony.xwork2.ActionSupport;

public class ReportDemo extends ActionSupport {
	private List<Account> accountList;

	public void setAccountList(List<Account> accountList) {
		this.accountList = accountList;
	}

	public List<Account> getAccountList(){
		List<Account> result = new ArrayList<Account>();
		result.add(new Account("1", "2007-19-38", "204.38"));
		result.add(new Account("2", "2008-09-25", "67382"));
		result.add(new Account("3", "2002-03-02", "12456"));
		return result;
	}
}

(3)配置struts.xml

<package name="myreport" extends="jasperreports-default" namespace="/report">
   		<action name="export" class="export">
   			<result name="success" type="jasper">
   				<param name="location">WEB-INF\jasperTemplet\testreport.jasper</param>
   				<param name="format">HTML</param>
   				<param name="dataSource">accountList</param>
   			</result>
   		</action>
   </package>

注意：format项值html必须全部大写；dataSource不能写成datasource或其他；accountList为action中的vo集合；testreport.jasper是iReport事先生成好的报表模板文件

（4）jsp调用

<form id="report" action="report/export.action">
	<input type="submit" value="生成报表"/>

(5)补充 这里用到个类Account是用来封装报表的记录对象的

public class Account {
	private int count_id;
	private String count_time;
	private float count_money;

	public Account(){}
	public Account(int id, String date, float num){
		this.count_id = id;
		this.count_time = date;
		this.count_money = num;
	}
	public int getCount_id() {
		return count_id;
	}
	public void setCount_id(int count_id) {
		this.count_id = count_id;
	}
	public String getCount_time() {
		return count_time;
	}
	public void setCount_time(String count_time) {
		this.count_time = count_time;
	}
	public float getCount_money() {
		return count_money;
	}
	public void setCount_money(float count_money) {
		this.count_money = count_money;
	}

}

注意：属性名必须与报表模板定义的字段名一致
