MyEclipse_搭建SSH框架

1.新WEB工程，并把编码设为utf-8：XbyOA->Properties->others->utf-8；

2.添加框架环境：Junit + Struts2 + Hibernate + Spring；

  【加jar包 + 拷配置文件 + 修改配置文件】
  【1】XbyOA->bulid path->Add Library->JUnit

  【2】Struts2: 加jar包，struts.xml, web.xml
-----------------------------------------------------------------------------------------------------------------------------------------------------------
web.xml:  

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
 </filter>

 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
-----------------------------------------------------------------------------------------------------------------------------------------------------------

struts.xml：

<struts>
 <!-- 配置为开发模式 -->
 <constant name="struts.devMode" value="true" />

 <!-- 把配置名配置为action -->
 <constant name="struts.action.extension" value="action" />

 <!-- 把主题配置为simple -->
 <constant name="struts.ui.theme" value="simple" />

 <package name="default" namespace="/" extends="struts-default">
 
 </package>
 <!-- Add packages here -->
</struts>

【提示】windows—>preferences->xml.catalog->dtd文件
-----------------------------------------------------------------------------------------------------------------------------------------------------------
     【3】Hibernate: 加jar包，hibernate.cfg.xml, *.hbm.xml
          核心包 + 必须包 + jpa + c3p0 + jdbc
-----------------------------------------------------------------------------------------------------------------------------------------------------------     
【hibernate.cfg.xml】
<hibernate-configuration>
    <session-factory>
        <!--1 数据库连接信息 5项 -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.jdbc.mysql.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql:///xbyoa</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">root</property>
       
        <!--2 其他配置 ： 自动建表  显示sql语句 二级缓存-->
        <property name="show_sql">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
       
        <!--3 导入映射文件 -->
    </session-factory>
</hibernate-configuration>
-----------------------------------------------------------------------------------------------------------------------------------------------------------     
      【4】Spring: 加jar包，applicationContext.xml/beans.xml
          lib: spring.jar(dist里) + AQP:（动态代理：aspectj里的）(子类代理：cglib里的）+ commmons-logging,jar(jakarta-commons里的日志包)
-----------------------------------------------------------------------------------------------------------------------------------------------------------     
【applicationContext.xml】
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop                                       
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
 <!-- 自动扫描与装配bean -->
 <context:component-scan base-package="xby.oa"></context:component-scan>
</beans>

-----------------------------------------------------------------------------------------------------------------------------------------------------------     
3.整合SSH：整合Struts2 + Spring  整合Hibernater + Spring；

-----------------------------------------------------------------------------------------------------------------------------------------------------------     
    1，在web.xml中配置Spring的监听器
    <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
 <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath:applicationContext*.xml</param-value>
    </context-param>
  
-----------------------------------------------------------------------------------------------------------------------------------------------------------     
    2，加一个jar包：Struts2-Spring-...
-----------------------------------------------------------------------------------------------------------------------------------------------------------     
   Spring与Struts2整合
 1，IOC 管理对象：帮助注入和装配对象
 2，AOP 事务管理
        整合前Struts2是通过反射机制来生成实例，整合后Struts2则是从Spring容器里拿对象。

   Hibernate与Spring整合
 1，管理SessionFactory实例（只需要一个）
 2，声明式事务管理

这样配置一个bean，相当于通过反射调用它默认的构造方法；接着指定property，相当于调用这个对象的seter方法给它注入属性
       <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory">
           </property>
       </bean>
