整合Struts2+JasperReport Web报表应用示例

整合Struts2+JasperReport Web报表应用示例

JasperReports作为一种优秀且开源的报表引擎，不利用太可惜了。同时，借助开源的JasperReports模板设计利器iReports，可以可视化的设计报表模板。基于Web的报表在很多项目中都是需要的。而随着Struts2的流行，就应该研究一下在Struts2下如何利用JasperReports进行报表输出。本示例比较简单，采用的数据源即为JavaBean，而没有采用复杂的数据库，其实原理是一样的。只是传递给JasperReports的参数随着连接方式的变化而略加修改而已。

一 准备工作

所使用的类库及Jar包如下图所示：

图1.使用的Jar包

开发环境：MyEclipse6.0+Eclipse3.3+JDK6.0+Tomcat6.0+Struts 2.0.11。当然，本该所提供的源代码下载中没有提供相关的lib，因为文件大太，如果需要，请留下email。.
    另外下载Jasperreport以及可视化模板iReport的网子http://jasperforge.org/

二 设计报表模板

本例中采用JavaBean作为数据源，用于显示People对象的一些基本属性，如所在序号、城市、姓名、地址，并对同一城市的人员进行汇总小结显示。

至于如何在iReports中设计模板文件，请在网上参考其它文档。这里不再详细解读，或有时间俺再另写文章来具体讲解如何在iReports中设计报表模板。WebRoot"jasper"jasper_template.jrxml代码如下：

这里需要说明的是，由于俺们中国的中文比较特殊，由此在PDF中显示的时候，需要一些额外的Jar包字体来支持。因此需要下载iTextAsian.jar包，此包专门用于显示亚洲的字符。只不过iReport3.0.0以后就已经含了些包。

三设计JavaBean

由本例中没有使用数据库，而是使用JavaBean作为JRDataSource，来传递给JasperReports作为数据源，因此只需要设计JavaBean。"src"com"sterning"PeopleBean.java的代码很简单，只在字个字段：city、id、name、street，代码如下所示：

package com.sterning;

public  class PeopleBean
{
    private String city = null;
    private Integer id = null;
    private String name = null;
    private String street = null;

    public PeopleBean(
        String pcity,
        Integer pid,
        String pname,
        String pstreet
        )
    {
        city = pcity;
        id = pid;
        name = pname;
        street = pstreet;
    }

    public PeopleBean getMe()
    {
        return this;
    }

    public String getCity()
    {
        return city;
    }

    public Integer getId()
    {
        return id;
    }

    public String getName()
    {
        return name;
    }

    public String getStreet()
    {
        return street;
    }
}

 

四编译模板

其实表面上说是填充数据，其实就是填充一个List。具体的工具都是交给我们的JasperReports去完成。JasperReports要完成数据的填充工作，要经历将编译（将模板文件.jrxml编译成.jasper文件）、加载（加载.jasper文件）、填充（从数据源中取得数据并填充到.jasper二进制文件中）三大步骤。src"com"sterning"JasperAction.java，其代码如下所示：

package com.sterning;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import net.sf.jasperreports.engine.JasperCompileManager;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public  class JasperAction  extends ActionSupport  {
    private static final long serialVersionUID = 1L;

    private List<PeopleBean> myList;

    public String execute() throws Exception {
        //添加数据
        PeopleBean p1=new PeopleBean("长沙", new Integer(9), "李化", "天洒路");
        PeopleBean p2=new PeopleBean("长沙", new Integer(22), "王小样", "呆小路564");
        PeopleBean p3=new PeopleBean("南昌", new Integer(23), "王奸可", "小顺路");
        PeopleBean p4=new PeopleBean("南昌", new Integer(32), "李洒", "顺濉路");
        PeopleBean p5=new PeopleBean("武汉", new Integer(39), "张中尖", "天洒路");
        PeopleBean p6=new PeopleBean("武汉", new Integer(35), "陈主宁", "天河路５６４");
        myList = new ArrayList<PeopleBean>();
        myList.add(p1);
        myList.add(p2);
        myList.add(p3);
        myList.add(p4);
        myList.add(p5);
        myList.add(p6);

        try {
            String reportSource;
            reportSource = ServletActionContext.getServletContext()
                    .getRealPath("/jasper/jasper_template.jrxml");
            File parent = new File(reportSource).getParentFile();
            //将.jrxml模板文件编译成为.jasper文件,当然,其文件名可以指定,如果没指定,则与.jrxml文件名一样.只是后缀不同而已
            JasperCompileManager.compileReportToFile(reportSource, new File(
                    parent, "compiled_jasper_template.jasper")
                    .getAbsolutePath());
        } catch (Exception e) {
            e.printStackTrace();
            return ERROR;
        }
        return SUCCESS;
    }

    public List getMyList() {
        return myList;
    }
}

 

五配置Struts2文件

前面这些工作都是为JasperReports而作的。接下来就是将JasperReports集成到Struts2中。

1． Web.xml

首先是Web.xml。这个文件配置比较简单，也比较常规，没什么好说，代码如下WebRoot"WEB-INF"web.xml：

<? xml version="1.0" encoding="UTF-8" ?>
< web-app  version ="2.4"  xmlns ="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation ="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >
     < filter >
         < filter-name >struts2 </ filter-name >
         < filter-class >
            org.apache.struts2.dispatcher.FilterDispatcher
         </ filter-class >
         < init-param >
             < param-name >config </ param-name >
             < param-value >
                struts-default.xml,struts-plugin.xml,struts.xml
             </ param-value >
         </ init-param >
     </ filter >
     < filter-mapping >
         < filter-name >struts2 </ filter-name >
         < url-pattern >/* </ url-pattern >
     </ filter-mapping >

     <!--  The Welcome File List  -->
     < welcome-file-list >
         < welcome-file >index.jsp </ welcome-file >
     </ welcome-file-list >
</ web-app >

 

2． struts.xml

按理说struts.xml配置文件应该更加简单，但这里由于集成了JasperReports，所以看上去要复杂一点。先来看代码：src" struts.xml：

<? xml version="1.0" encoding="UTF-8"  ?>
<! DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd" >
< struts >
     < package  name ="default"
        extends ="struts-default,jasperreports-default" >
         < action  name ="PDF"  class ="com.sterning.JasperAction" >
             < result  name ="success"  type ="jasper" >
                 < param  name ="location" >
                    /jasper/compiled_jasper_template.jasper
                 </ param >
                 < param  name ="dataSource" >myList </ param >
                 < param  name ="format" >PDF </ param >
             </ result >
         </ action >
         < action  name ="HTML"  class ="com.sterning.JasperAction" >
             < result  name ="success"  type ="jasper" >
                 < param  name ="location" >
                    /jasper/compiled_jasper_template.jasper
                 </ param >
                 < param  name ="dataSource" >myList </ param >
                 < param  name ="format" >HTML </ param >
             </ result >
         </ action >
         < action  name ="XML"  class ="com.sterning.JasperAction" >
             < result  name ="success"  type ="jasper" >
                 < param  name ="location" >
                    /jasper/compiled_jasper_template.jasper
                 </ param >
                 < param  name ="dataSource" >myList </ param >
                 < param  name ="format" >XML </ param >
             </ result >
         </ action >
         < action  name ="CSV"  class ="com.sterning.JasperAction" >
             < result  name ="success"  type ="jasper" >
                 < param  name ="location" >
                    /jasper/compiled_jasper_template.jasper
                 </ param >
                 < param  name ="dataSource" >myList </ param >
                 < param  name ="format" >CSV </ param >
             </ result >
         </ action >
         < action  name ="XLS"  class ="com.sterning.JasperAction" >
             < result  name ="success"  type ="jasper" >
                 < param  name ="location" >
                    /jasper/compiled_jasper_template.jasper
                 </ param >
                 < param  name ="dataSource" >myList </ param >
                 < param  name ="format" >XLS </ param >
             </ result >
         </ action >
     </ package >
</ struts >

 

这里，当调用JasperAction的execute()方法成功后，返回后，可见有三个参数：location告诉JasperReports数据填充类二进制的.jasper文件的位置，dataSource指明使用什么数据源，format指明报表输出的格式。

 

六 页面文件

Index.jsp的代码非常的简单，如下：

<% @ page language="java" pageEncoding="GB2312" %>
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" >
< html >
     < head >
         < title >Struts2+ JasperReports 使用示例 </ title >
     </ head >
     < body >
         < a  href ="HTML.action" >HTML </ a >
         < br >
         < a  href ="PDF.action" >PDF </ a >
         < br >
         < a  href ="XML.action" >XML </ a >
         < br >
         < a  href ="CSV.action" >CSV </ a >
         < br >
         < a  href ="XLS.action" >XLS </ a >
     </ body >
</ html >
