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;

@Override
public 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
