iReport + jasperreports + struts 2 集成開發報表

項目準備：

                1、使用iRrport 設計一個jrxml文件並把其編譯成jasper格式的文件

                2、下載項目中所需要的包，基本上是下面這些，下面的這些我是使用SSH2的框架，可以看情況而使用那些包

項目開發《本項目使用的是javabean作爲數據源》：

JavaBean:

package com.jr.bean;

import java.math.BigDecimal;

/**
 * 員工信息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("張三");
			em.setDetpName("遊戲部");
			em.setSaly(new BigDecimal(4500));
			list.add(em);
			em = new Employee();
			em.setId(1002);
			em.setDetpName("開發部");
			em.setSaly(new BigDecimal(3500));
			em.setName("王五");
			list.add(em);
			em = new Employee();
			em.setId(1003);
			em.setDetpName("開發部");
			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;
	}
	
	
	
	
}

項目問題：打印HTML格式圖片不出來

解決辦法：

在struts.xml文件中寫以下代碼

在web.xml中配置servlet

備註：struts.xml文件中的

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

image訪問的路徑就是web.xml文件中配置的servlet訪問的路徑

這樣就可以解決圖片不顯示的問題了，但是訪問這個action後綴名必須帶上.action，否則攔截不到
