jasperreports+iReport+jatoolsPrinter制作报表笔记

此文章是基于　　EasyUI+Knockout实现经典表单的查看、编辑

一. 准备工作

　　1. 点击此下载相关的文件，并把 ims 文件夹放到 ims 工程对应的路劲下

　　2. 参考网址：杰创打印控件

二. 安装ant

　　1. 解压apache-ant-1.9.4-bin到任意地方

　　2. 配置环境变量ANT_HOME为apache-ant-1.9.4-bin解压后的目录地址，如D:Downloadapache-ant-1.9.4

　　3. 在环境变量CLASSPATH中加入%ANT_HOME%lib;

　　4. 在环境变量Path中加入%ANT_HOME%in;

　　5. 在cmd下测试ant是否安装正确，命令：ant -version 安装成功显示ant的版本号，出错，自己网上查

三. 安装iReport，制作报表的工具

　　1. 直接双击iReport-5.6.0-windows-installer.exe进行安装

四. jasperreports源码与例子

　　1. 解压jasperreports-5.6.0-project.zip

　　2. 在含有build.xml文件的目录执行ant -p 命令可查看可执行哪些ant命令

　　3. /jasperreports-5.6.0/src下是源码，可在/jasperreports-5.6.0/目录下执行ant jar来编译源代码，

　　　　最后在/jasperreports-5.6.0/dist/下生成jasperreports-5.6.0.jar包

　　4. /jasperreports-5.6.0/demo/samples/下是实例

　　5. /jasperreports-5.6.0/demo/samples/webapp/下是标准的实例，可在其目录下执行ant war命令生成war包，可在tomcat下直接部署运行

五. 制作一张报表

iReport设计报表应注意：在含有中文的地方，设置如下，防止pdf导出中文无法显示：

　　　　　　Font name: 宋体 (中文字体)

　　　　　　PDF font name: STSong-Light

　　　　　　PDF Encoding: UniGB-UCS2-H(Chinese Siplified)

　　　　　　PDF Embeded: √

六. 报表在项目中的应用

　　1. 将制作好的报表（以jrxml结尾的文件）拷贝到WebContent eportjasperreport 目录下

　　2. jasperreports-5.6.0-project 的 lib 和 dist 目录下可找到如下jar包：

groovy-all-2.0.1.jar
iText-2.1.7.js2.jar
iTextAsian.jar
jackson-annotations-2.1.4.jar
jackson-core-2.1.4.jar
jackson-databind-2.1.4.jar
jasperreports-5.6.0.jar

　　3. 添加报表的数据源类

　　　　BaseJRDataSource.java，数据源接口　

package com.ims.interfaces.report.datasource;

import java.util.Map;

import net.sf.jasperreports.engine.JRDataSource;

public interface BaseJRDataSource extends JRDataSource{
    public JRDataSource getInstance(Map parameters);
    public Map<String,Object> getReportParams(Map parameters);
}

View Code

　　　　ReceiveDataSource.java，材料收料单报表的数据源类

package com.ims.interfaces.report.datasource.mms;

import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import com.ims.interfaces.report.datasource.BaseJRDataSource;
import com.ims.service.mms.ReceiveBS;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRField;

public class ReceiveDataSource implements BaseJRDataSource{
    @Autowired
    private ReceiveBS receiveBS;
    
    private List<Map<String,Object>> data = new ArrayList<Map<String,Object>>();
    private int index = -1;
    
    @Override
    public Object getFieldValue(JRField field) throws JRException {
        Object value = null;        
        String fieldName = field.getName();
        
        if ("billNo".equals(fieldName)){
            value = data.get(index).get("billNo");
        }else if ("rownum".equals(fieldName)){
            value = index+1;
        }else if ("supplierName".equals(fieldName)){
            value = data.get(index).get("supplierName");
        }else if ("warehouseName".equals(fieldName)){
            value = data.get(index).get("warehouseName");
        }else if("receiveDate".equals(fieldName)){
            SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            value = (null!=data.get(index).get("receiveDate")?formatter.format(data.get(index).get("receiveDate")):"");
        }else if("totalMoney".equals(fieldName)){
            value = data.get(index).get("totalMoney");
        }
        
        return value;
    }

    @Override
    public boolean next() throws JRException {
        index++;
        return (index < data.size());
    }

    @Override
    public JRDataSource getInstance(Map parameters) {
        data = receiveBS.findPage(parameters).getRows();
        index = -1;
        return this;
    }

    @Override
    public Map<String, Object> getReportParams(Map parameters) {
        parameters.put("dataCount", data.size());
        return parameters;
    }

}

　　4. applicationInterface.xml，在spring的配置文件中添加数据源类的bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">  
    
    <!-- jasperreport -->
    <bean id="mmsReceiveDataSource" class="com.ims.interfaces.report.datasource.mms.ReceiveDataSource" />
    <!-- jasperreport -->
</beans>

　　5. showReport.jsp，报表显示页面；打印控件采用jatoolsPrinter.cab，需要tomcat服务以进程的方式启动
