1----SSH综合实战(Struts+Spring+Hibernate)----我的智囊团(介绍及环境搭建)

开发工具:Eclipse + MySQL + Tomcat + ConnectionPool

注意:在使用SSH开发中,数据库是不关闭的,因此使用ConnectionPool是最合适的。

项目主要功能:                                

a、前台

1)用户登录、注册、修改个人信息

2)查询个人提过的问题

3)检索问题

b、后台

1)管理栏目:一级栏目、二级栏目                

2)管理用户

3)维护管理员信息

4)用户等级维护

5)问题维护


数据库表:













mldn.sql

create database mldn;

use mldn;

drop table if exists admin;

drop table if exists answer;

drop table if exists subitem;

drop table if exists item;

drop table if exists question;

drop table if exists user;

为项目添加SSH支持:添加的顺序:Spring、Hibernate、Struts

数据库名称:mldn
数据源名称:jdbc/mldn
数据库连接地址:jdbc:mysql://localhost:3307/mldn
数据库驱动程序:org.git.mm.mysql.Driver



选择项目属性,进入构建路径,因为在加入时由于开发工具的问题,所以最后确认一下是否所有的包已经被成功地导入到了项目之中。

下面首先配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
    <bean id="dataSource"

        <property name="jndiName" value="java:comp/env/jdbc/mldn"></property>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

        <property name="sessionFactory">
            <ref bean="sessionFactory"/>
        </property>
    </bean>   
</beans>


编写web.xml(代码里加粗的为自己写)

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

编写struts-config.xml

new/.../Struts1.2 Plugin


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

要求:关于乱码解决问题,使用过滤器解决中文乱码问题

编写EncodingFilter.java

在整个程序之中需要一下两个部分的支持
1)MD5加密
    用户登录案例,所有的用户名和密码都是以明文形式出现的,那么这就造成了一个不安全的隐患,如果数据库被黑了,则所有的信息也就可以看见了,所以为了保证数据的安全性,使用MD5加密,MD5是不可逆编码。
2)验证码
    在各个论坛无论是登录还是发表信息,都需要在最后添加一段额外的代码,这些代码就是验证码,作用是防止灌水。

编写MD5Code.java

它其实是一个小工具,可以从网上下载,下面来验证MD5

编写TestMD5.java

package org.lxh.myzngt.test;

import org.lxh.myzngt.util.MD5Code;

public class TestMD5 {
    public static void main(String [] args) {
        MD5Code md5 = new MD5Code();
        String str = "lixinghua";
        System.out.println(md5.getMD5ofStr(str));
        str = "lixinghuadfadafasfdafadsfdasdfasfds";
        System.out.println(md5.getMD5ofStr(str));
        System.out.println(md5.getMD5ofStr(str).equals(md5.getMD5ofStr(str)));
        System.out.println(md5.getMD5ofStr(str).equals(md5.getMD5ofStr("abcdef")));
        System.out.println(md5.getMD5ofStr(str).length());
    }
}
