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：MyEclipse5.5+Eclipse3.2+JDK5.0+Tomcat5.5+Struts 2.0.6。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。
源代码下载：Struts2AndJasperReport.rar
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。
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;
}
}
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;
}
}
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 >
< 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" >

</ action >
< action name ="HTML" class ="com.sterning.JasperAction" >

< 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 >
<! 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"

< action name ="PDF" class ="com.sterning.JasperAction" >
< result name ="success" type ="jasper" >

</ 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 >
