jasperreports+iReport+jatoolsPrinter制作報表筆記

此文章是基於　　EasyUI+Knockout實現經典表單的查看、編輯

 

一. 准備工作

　　1. 點擊此下載相關的文件，並把 ims 文件夾放到 ims 工程對應的路勁下

　　2. 參考網址：傑創打印控件

 

二. 安裝ant  

　　1. 解壓apache-ant-1.9.4-bin到任意地方  

　　2. 配置環境變量ANT_HOME為apache-ant-1.9.4-bin解壓后的目錄地址，如D:\Download\apache-ant-1.9.4  

　　3. 在環境變量CLASSPATH中加入%ANT_HOME%\lib;  

　　4. 在環境變量Path中加入%ANT_HOME%\bin;  

　　5. 在cmd下測試ant是否安裝正確，命令：ant -version     安裝成功顯示ant的版本號，出錯，自己網上查

 

三. 安裝iReport，制作報表的工具  

　　1. 直接雙擊iReport-5.6.0-windows-installer.exe進行安裝

 

四. jasperreports源碼與例子  

　　1. 解壓jasperreports-5.6.0-project.zip  

　　2. 在含有build.xml文件的目錄執行ant -p 命令可查看可執行哪些ant命令  

　　3. /jasperreports-5.6.0/src下是源碼，可在/jasperreports-5.6.0/目錄下執行ant jar來編譯源代碼，

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

　　4. /jasperreports-5.6.0/demo/samples/下是實例  

　　5. /jasperreports-5.6.0/demo/samples/webapp/下是標准的實例，可在其目錄下執行ant war命令生成war包，可在tomcat下直接部署運行  

 

五. 制作一張報表  

      iReport設計報表應注意：在含有中文的地方，設置如下，防止pdf導出中文無法顯示：    

　　　　　　Font  name:    宋體 (中文字體)        

　　　　　　PDF font name:   STSong-Light        

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

　　　　　　PDF   Embeded: √

 

六. 報表在項目中的應用  

　　1. 將制作好的報表（以jrxml結尾的文件）拷貝到\WebContent\report\jasperreport\ 目錄下  

　　2. jasperreports-5.6.0-project 的 lib 和 dist 目錄下可找到如下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. 添加報表的數據源類

　　　　BaseJRDataSource.java，數據源接口 　

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);
}

　　　　ReceiveDataSource.java，材料收料單報表的數據源類

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的配置文件中添加數據源類的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"
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        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，報表顯示頁面；打印控件采用jatoolsPrinter.cab，需要tomcat服務以進程的方式啟動

    catch(Exception e){}
    
    if (pageIndex < 0){
        pageIndex = 0;
    }

    if (pageIndex > lastPageIndex){
        pageIndex = lastPageIndex;
    }
    
    HtmlExporter exporter = new HtmlExporter();    
    StringBuffer sbuffer = new StringBuffer();

    exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

　　6. web.xml，若要支持pdf、img、excel、doc導出，需添加servlet

　　7. report.js

/***
 * 參數說明：{jasper:"report01.jasper",args:arr}
 * param.jasper:jasper文件名稱，最好不要用中文
 * param.ds:dataSource文件名稱，最好不要用中文
 * param.args:*格式待定*，暫時用數組,以后看使用什么格式方便可以再改
 * author: suxy.
 */
function openReport(win, param){
    var strFullPath = window.document.location.href;
    var strPath = window.document.location.pathname;
    var pos = strFullPath.indexOf(strPath);
    var prePath = strFullPath.substring(0, pos);
    var postPath = strPath.substring(0, strPath.substr(1).indexOf('/') + 1);
    var url = postPath;

    win_form.submit();
}

 

七. 效果展示

　　訪問：http://localhost:8080/ims/mms/receive.do，點擊 打印 按鈕

　　右上角的按鈕可以實現打印、pdf導出、word導出
