我用的是struts2.1.6,从struts2的自带的demo当中可以看到它的web.xml配置与之前的有点不同,有另外一种配置:
- <filter>
- <filter-name>Struts2</filter-name>
- <filter-class>
- org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
- </filter-class>
- </filter>
- <filter-mapping>
- <filter-name>Struts2</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
这样的配置可以在web.xml配置我们的serlvet,如果写成以前的写法你配置上serlvet会报错。
将我们设置的报表文件和编译文件放到WebRoot下面的jasper下面,添加struts2对jasperReport的插件。
构造我们的JavaBean如下(get,set方法省略了):
- public class Person {
- private String person_Id;
-
- private String person_name;
-
- private String person_age;
-
- private String person_address;
- }
构造我们的service:
- public class PersonService {
- public List<Person> getAllPerson() {
- List<Person> perList = new ArrayList<Person>();
- perList.add(new Person("101", "小博", "22", "湖北"));
- perList.add(new Person("102", "张三", "21", "湖南"));
- perList.add(new Person("103", "李四", "23", "江苏"));
- perList.add(new Person("104", "王五", "22", "上海"));
- return perList;
- }
- }
构造action:
- public class PersonAction extends ActionSupport {
-
- private List<Person> presonList = null;
-
- private Map<String, String> reportParameter = null;
-
- @Override
- public String execute() throws Exception {
- presonList = new PersonService().getAllPerson();
- reportParameter = new HashMap<String, String>();
- reportParameter.put("year", "2009");
- reportParameter.put("unit_mc", "武汉XX科技有限公司");
- return SUCCESS;
- }
-
- public String htmlView(){
- return SUCCESS;
- }
-
- public List<Person> getPresonList() {
- return presonList;
- }
-
- public void setPresonList(List<Person> presonList) {
- this.presonList = presonList;
- }
-
- public Map<String, String> getReportParameter() {
- return reportParameter;
- }
-
- public void setReportParameter(Map<String, String> reportParameter) {
- this.reportParameter = reportParameter;
- }
- }
struts配置如下:
- <!DOCTYPE struts PUBLIC
- "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
- "http://struts.apache.org/dtds/struts-2.0.dtd">
- <struts>
- <constant name="struts.action.extension" value="action" />

- <param name="dataSource">presonList</param>
- <param name="reportParameters">reportParameter</param>

- <!--
- location:是指我们刚才用iReport编译生成的jasper文件
- dataSource:是指我们执行的数据库查询结果,在testAction类里把这个结果查询出来,这个参数必须要有
- format:是指需要输出的类型,默认是PDF,其他的输出类型有:XML、HTML、XLS、CSV、RTF ,注意这里一定要大写
- reportParameters:jasperreport中的Parameters
- 除了这几个参数,还有下列参数:
- delimiter:是指如果输出类型为CSV的话,指定分割符,默认为“,”
- parse:是指是否解析location参数中的EL表达式,默认为 true
- contentDisposition:指定disposition,默认为“inline”,如果设为“attachment”就是强制下载
- documentName:输出的文件名
- imageServletUrl:生成图形的路径
- -->
- </package>
- </struts>
页面调用:
- <a href="PDF.action">PDF</a>
- <a href="XLS.action">XLS</a>
- <a href="XML.action">XML</a>
- <a href="CSV.action">CSV</a>
如果要想以HTML形式显示报表内容则还需要在web.xml配置jasperReport自带的一个servlet如下:
- <!-- JasperReport包中自带的Servlet,用来做为HTML形式显示报表的时候报表的图片,要在这里配置上,图片在jasperReport包中 -->
- <servlet>
- <servlet-name>JasperReportImageServlet</servlet-name>
- <servlet-class>
- net.sf.jasperreports.j2ee.servlets.ImageServlet
- </servlet-class>
- </servlet>
-
- <servlet-mapping>
- <servlet-name>JasperReportImageServlet</servlet-name>
- <url-pattern>/image</url-pattern>
- </servlet-mapping>
action中不需要修改,只需在struts.xml里添加一个HTML不配置如下:
- <action name="HTML" class="com.mengya.action.PersonAction">
- <result name="success" type="jasper">
- <param name="location">/jasper/preson.jasper</param>
- <param name="dataSource">presonList</param>
- <param name="reportParameters">reportParameter</param>
- <param name="format">HTML</param>
- <param name="imageServletUrl">
- <![CDATA[/image?image=]]>
- </param>
- </result>
- </action>
imageServletUrl的值就是上面的serlvet的路径,该servlet就是生成了一个图形,如果不配置该serlvet则页面上有图片没显示的样子。
页面调用如:
- <a href="HTML.action">HTML</a>
