我的智囊团构建全过程

ssh综合实战
（Struts+spring+hibernate)
(Eclipse + mysql+Tomcate+ConnectionPool)
注意：在使用过程中连接是不关闭的，所以用连接池

表
user
create table user
(
   id   INT AUTO_INCREMENT PRIMARY KEY ,
   userid                         VARCHAR(50)                  not null ,
   userpwd                        VARCHAR(50),
   userques                       VARCHAR(50),
   userans                        VARCHAR(50),
   usermail                       VARCHAR(50),
   integral                       int,
   grade                          int,
   sex                            VARCHAR(2),
   realname                       VARCHAR(50)
) ;
开发流程中，首先是搭建环境
1、创建表在mysql
在cmd中net start mysql
mysql -uroot -pmysqladmin
create database mldn;
user mldn;
复制表
commit;
show tables;

2、打开eclipse
项目位置f:\Eclipse\MyZNTProject(工作间）
3、新建项目（先配mysql驱动window-->preferences-->myEclipse-->Database Explore-->Drivers
-->new-->MySql Connector/J
-->jdbc:mysql//:localhost:3306/mldn
-->加入jars包mysql-connect-java-5.0.4.bin.jsr
-->Driver classname:org.git.mm.mysql.Driver
-->ok
4.进入DB Browser
建一个新连接试试
5、新建项目MyZhiNangTuanDemo
6、加spring+hibernate+struts
-->spring 包全选(可以查看包是否被全加进去了） ApplicationContext.xml
－->hibernate包全选(hibernate 3.1)　sessionFactory
用Use JNDI DataSource(dataSource)
(数据源名称：jdbc/mldn)
DataSource:java:comp/env/jdbc/mldn
Dialect:mysql
不建工厂
选全replace包
-->struts(struts 1.2)
org.lxh.myzngt.struts
7.配applicationContext.xml
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
  <property name="sessionFactory">
  <ref bean="sessionFactory"/>
</property>
</bean>
(也可以不配hibernateTemplate直接给dao注sessionFactory)
sessionFactory中加
<prop key="hibernate.connection.autocommit">true</prop>表示　自动　提交　
8.web.xml
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<servlet>
  <servlet-name>context</servlet-name>
  <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
(其实也可以配成<listener>)

9.配struts-config.xml
-->new struts1.2 plugin
-->ContextLoaderPlugIn
-->contextConfigLocation
-->WEB-INF/classes/applicationContext.xml

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>

10.使用过滤器解决乱码问题
－－>新建EncodingFilter
------>interface:javax.servlet.Filter
在doFilter中
req.setCharacterEncoding("");
chain.doFilter(req.resp);
在web.xml中加
<filter>
  <filter-name>encoding</filter-name>
  <filter-class>org.lxh.myzngt.filter.EncodingFilter</filter-class>
  <init-param>
     <param-name>charset</param-name>
     <param-value>gbk</param-vale>
</filter>
<filter-mapping>
   <filter-name>encoding</filter-name>
   <url-pattern>/*</usl-pattern>
</filter-mapping>
在EncodingFilter中
加private String charset = null;
在init中加
this.charset = arg0.getInitParameter("charset");
把doFilter中设为this.charset

11.md5加密
在util下新建类
----------------------------------------------------------------------------------
MD5Code.java
package org.lxh.myzngt.util;

使用时md5.getMD5ofStr("dsfasdfasdf");

12.验证码文件image.jsp


13.系统结构
｜－jsp
|-images
|-js
|-css
|-inc(要导入的文件）


14.数据源配置
在tomcate/conf/server.xml文件中加
-->在</Host></Engine></Service></Server>前面加<context>配置
(工作的根目录为F:\Eclipse\MyZNTProject\MyZhiNangTuanDemo\WebRoot
放到docBase中,Resource name="jdbc/mldn",url=jdbc:mysql://localhost:3306/mldn)

13.直接起动tomcat服务器(不用在eclipse中起）
测试http://localhost:8080/zhinangtuan　　（即为数据源中<context path=/zhinangtuan)

14.在jsp下建admin,把分页文件split.jsp

15.用户注册功能
register.sjp
<jsp:include flush="true" page="inc/template"/>导入　文件　
<html:form action="" method="post">
  <html:text property="userid"/>
</body>
</html:html>
-->新建sturts1.2 Form ,Action &Jsp
-->user case :user
-->加属性id,userid,username,userques......
-->建一个errors.jsp   <h1>程序出现错误<html:errors/><a href="" onclick="history.back()">返回
-->在struts-config.xml中配<forward>
-->在register.jsp页中加<input type="hidden" name="status" value="regist">
--><input type="hidden" name="type" value="1">
作用是type=1表是注册功能要验证id password　否为空
在userForm中也要加private int type生成get set方法
在validate方法中
ActionErrors errors = new ActionErrors();
if(type==1){
  //注册
  if(this.userid==null || "".equals(this.userid)){
     errors.add("userid",new ActionMessage("user.userid.null"));
}
  if()......
  if
}
其中user.userid.null为读取资源文件user.userid.null＝user name null

16.写Action
//先判断验证码是否正确
UserForm userForm = (UserForm) form;
String code = (String)request.getSession().getAttribute("ccode");(这是image.jsp文件　保存在session上的）
String checkcode = userForm.getCheckcode();用户输入的
if(!(checkcode.equals(ccode))){
  ActionMessages errors = new ActionMessages();
  errors.add("checkcode",new ActionMessage("check.error"));
  super.saveErrors(request,errors);
  return mapping.getInputForward();这里即为<action 中的input="jsp/errors.jsp那个页面">
}

User user = new User;
user.setUserid(userForm.getUserid);
.....
try{
   this.service.register(user);
    request.getSession().setAttribute("userid",user.getUserid());
    request.getSession().setAttribute("grade"),user.getGrade());
   return mapping.fingForward("registersuccess");
} catch(Exception e){
   e.printStackTrace();
　 return mapping.findForward("registerfailure");
  }

17.写IUserDAO接口和实现
---vo内容和表一样
--->HibernateDaoSupport
--public void register(User user) throws Exception;
--------> super.getSession().save(user);

---->生成映射文件并修改它去掉catory="";

18.配applicationContext.xml
<bean id ="dao">

19.在DispatchAction中加service层的属性
再接着写action

20.在index.jsp页面中
<jsp:include flush="true" page="inc/template.htm"/>
<logic:present name="userid" scope="session">
  欢迎${userid}等级${grade}
  <a href="">个人中心</a>
</logic:present>
