Action：

package com.test.action;

import java.awt.Font;

import java.util.List;

import java.util.Map;

import org.jfree.chart.ChartFactory;

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.CategoryAxis;

import org.jfree.chart.axis.CategoryLabelPositions;

import org.jfree.chart.axis.NumberAxis;

import org.jfree.chart.plot.CategoryPlot;

import org.jfree.chart.plot.PlotOrientation;

import org.jfree.chart.title.TextTitle;

import org.jfree.data.category.CategoryDataset;

import org.jfree.data.category.DefaultCategoryDataset;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class ViewResultAction extends ActionSupport

{

private JFreeChart chart;//此定义是不能改变的

private List<String> interest;

public JFreeChart getChart()

{

chart = ChartFactory.createBarChart3D("兴趣统计结果", "项目", "结果", this

.getDataset(), PlotOrientation.VERTICAL, false, false, false);

chart.setTitle(new TextTitle("兴趣统计结果",new Font("黑体",Font.BOLD,22)));

CategoryPlot plot = (CategoryPlot)chart.getPlot();

CategoryAxis categoryAxis = plot.getDomainAxis();

categoryAxis.setLabelFont(new Font("宋体",Font.BOLD,22));

categoryAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_45);//倾斜度

NumberAxis numberAxis = (NumberAxis)plot.getRangeAxis();

numberAxis.setLabelFont(new Font("宋体",Font.BOLD,22));

return chart;

}

public List<String> getInterest()

{

return interest;

}

public void setInterest(List<String> interest)

{

this.interest = interest;

}

@Override

public String execute() throws Exception

{

return SUCCESS;

}

@SuppressWarnings("unchecked")//应该放到model里面

private void increaseResult(List<String> list)

{

ActionContext context = ActionContext.getContext();

Map map = context.getApplication();

for (String str : list)

{

if (null == map.get(str))

{

map.put(str, 1);

}

else

{

map.put(str, (Integer) map.get(str) + 1);

}

@SuppressWarnings("unchecked")

private CategoryDataset getDataset()

{

DefaultCategoryDataset dataset = new DefaultCategoryDataset();

this.increaseResult(this.getInterest());

ActionContext context = ActionContext.getContext();

Map map = context.getApplication();

dataset.setValue((Integer) map.get("football"), "", "足球");

dataset.setValue((Integer) map.get("basketball"), "", "篮球");

dataset.setValue((Integer) map.get("volleyball"), "", "排球");

dataset.setValue((Integer) map.get("badminton"), "", "羽毛球");

return dataset;

}

Struts.xml配置

解压：struts2-jfreechart-plugin-2.0.11.jar

修改struts-plugin.xml

<result-types>

<result-type name="chart" class="org.apache.struts2.dispatcher.ChartResult">

</result-type>

</result-types>

</package>

再重新打包：

Cmd ，转到struts-plugin.xml目录，jar就可以看到各种命令

使用如下命令就可以打包：

jar cvf struts2-jfreechart-plugin-2.0.11.jar (产生的文件名)-c *

改继承关系：

</result>

</action>

Struts2和spring整合

加插件：struts2-spring-plugin-2.0.11.jar

选择MyEclipse的支持：spring2.0 core librarys和web选择copy checked library。。。。

建立接口

package com.test.service;

public interface LoginService

{

public boolean isLogin(String username, String password);

}

实现：

package com.test.service.impl;

import com.test.service.LoginService;

public class LoginServiceImpl implements LoginService

{

public boolean isLogin(String username, String password)

{

if ("hello".equals(username) && "world".equals(password))

{

return true;

}

return false;

}

在action中提供set方法：

public class LoginAction extends ActionSupport

{

private String username;

private String password;

private LoginService loginService;

public void setLoginService(LoginService loginService)

{

this.loginService = loginService;

}

public String execute() throws Exception

{

if (loginService.isLogin(username, password))

{

return SUCCESS;

}

else

{

return INPUT;

}

Struts.xml

//class 是自己起的名字

<result name="success">/result.jsp</result>

<result name="input">/login2.jsp</result>

</action>

Spring配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<beans

xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

//下面的ID要和struts中的自定义的class名称一样，让它来管理

</property>

</bean>

</beans>

配置监听器：

Web.xml

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

同时把applicationContext.xml放到web-inf下或指定也行。

Struts2整合jasperReport报表整合网址：www.jasperforge.org

辅助工具：iReport

水晶报表 Business object

Eclipse business intelligence and Reporting tool birt :www.eclipse.org/birt

用iReport2.0.5建立报表和执行报表，链接数据库驱动

补充：将驱动放到它的lib目录下面，启动时就会自动加载进来

数据库工具：Toad for MySql

建立数据库

用iReport2.0.5链接数据库

PTF

Itext用于Java转化ptf的格式，但不支持中文。下载itextasina.jar放到：C:/Documents and Settings/Administrator/桌面/向电脑桌面/Incoming/struts-2.1.8.1-all/iReport-3.7.0/ireport/modules/ext 文件下重新启动，修改字体属性，fort下的PDF font name 为stsong-light和改PDF encoding为UCS2-H(Chinese Simplified)再把font name改成宋体

Struts2+hibernate3.2+spring2.0

前期工作：

先加hibernate支持：annotations和core。选择 copy checked….下面的选择都不选让spring进行管理

增加spring2.0支持，选择aop，core persistence core和persistence jdbc以及webliberaries支持或只加官网spring.jar即可

去到 aop Builder 去掉create spring sessionFactory

增加struts支持：freemarker.2.3.8.jar ognl2.6.11.jar struts2-core-2.0.11.jar 和 xwork.2.0.4.jar和struts2-spring-plugin-2.0.11.jar

代码编写

在src下建立struts.Xml：

修改web.xml：

<filter-name>struts2</filter-name>

<filter-class>

org.apache.struts2.dispatcher.FilterDispatcher

</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

连接池一保证有dbcp连接池用命令进入MySQL : MySQL –uroot –proot

可以用工具 toad for MySQL

修改工具里面的 Bast support for multilingualism 就是选择utf-8的编码方式

选择 include bin directory inwindows path//增加到path下面

建立页面：主页

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@ taglib prefix="s" uri="/struts-tags"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>operation</title>

</head>

<body>

<h1><font color="red">Operation List</font></h1>

<s:a href="save.jsp">Save User</s:a> <br><br><br>

<s:a href="listUser.action">List Users</s:a>

</body>

</html>

保存页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@ taglib prefix="s" uri="/struts-tags"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

<s:form action="saveUser">

<s:textfield name="user.firstname" label="%{getText('firstname')}"></s:textfield>

上面的方式是取到资源文件内容

：<s:textfield name="user.firstname" label="firstname></s:textfield>//静态文本形式

<s:textfield name="user.lastname" label="%{getText('lastname')}"></s:textfield>

<s:textfield name="user.age" label="%{getText('age')}"></s:textfield>

<s:submit></s:submit>

</s:form>

</body>

</html>

建立模型驱动类也可以当实体类：

package com.test.bean;

public class User

{

private Integer id;

private String firstname;

private String lastname;

private int age;

设置getheset方法----

配置hbm、xml

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

</id>

<property name="firstname" type="string" column="firstname"

length="50">

</property>

<property name="lastname" type="string" column="lastname"

length="50">

</property>

</class>

</hibernate-mapping>

建立action

package com.test.action.user;

import java.util.Iterator;

import java.util.Map;

import java.util.Set;

import com.opensymphony.xwork2.ActionSupport;

import com.test.bean.User;
