iReport + jasperreports + struts 2 集成开发报表

项目准备：

                1、使用iRrport 设计一个jrxml文件并把其编译成jasper格式的文件

                2、下载项目中所需要的包，基本上是下面这些，下面的这些我是使用SSH2的框架，可以看情况而使用那些包

项目开发《本项目使用的是javabean作为数据源》：

JavaBean:

package com.jr.bean;import java.math.BigDecimal;/** * 员工信息bean * @author HRQ * */public class Employee {private Integer id;private String name;private BigDecimal saly;private String detpName;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public BigDecimal getSaly() {return saly;}public void setSaly(BigDecimal saly) {this.saly = saly;}public String getDetpName() {return detpName;}public void setDetpName(String detpName) {this.detpName = detpName;}}

action:

package com.jr.action;import java.math.BigDecimal;import java.util.ArrayList;import java.util.List;import com.jr.bean.Employee;import com.jr.service.IEmployeeService;import com.opensymphony.xwork2.ActionSupport;public class EmployeeAction extends ActionSupport{/** *  */private static final long serialVersionUID = 6093380186451210429L;private IEmployeeService emservice;private List<Employee> list;@Overridepublic String execute() throws Exception {if(list == null){list = new ArrayList<Employee>();Employee em = new Employee();em.setId(1001);em.setName("张三");em.setDetpName("游戏部");em.setSaly(new BigDecimal(4500));list.add(em);em = new Employee();em.setId(1002);em.setDetpName("开发部");em.setSaly(new BigDecimal(3500));em.setName("王五");list.add(em);em = new Employee();em.setId(1003);em.setDetpName("开发部");em.setSaly(new BigDecimal(3500));em.setName("serch");list.add(em);}return SUCCESS;}public String jasperImage(){return SUCCESS;}public IEmployeeService getEmservice() {return emservice;}public void setEmservice(IEmployeeService emservice) {this.emservice = emservice;}public List<Employee> getList() {return list;}public void setList(List<Employee> list) {this.list = list;}}

项目问题：打印HTML格式图片不出来

解决办法：

在struts.xml文件中写以下代码

在web.xml中配置servlet

备注：struts.xml文件中的

<param name="imageServletUrl"><![CDATA[/image?image=]]></param>  

image访问的路径就是web.xml文件中配置的servlet访问的路径

这样就可以解决图片不显示的问题了，但是访问这个action后缀名必须带上.action，否则拦截不到
