SSH的Eclips环境搭建

一.创建数据库名字为：dungouoa

create database dungouoa default character set utf8;
mysql> show create database dungouoa;
+----------+-------------------------------------------------------------------+
| Database | Create Database |
+----------+-------------------------------------------------------------------+
| dungouoa | CREATE DATABASE `dungouoa` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+----------+-------------------------------------------------------------------+

二.创建eclips的工程
@1创建web工程，编码设为utf-8

@2添加框架环境
Junit

@1Structs2

添加jar包，

修改structs.xml，

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <!-- 配置为开发模式-->
    <constant name="struts.devMode" value="true" />
    <!--把扩展名配置为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>

web.xml的structs2过滤器拷贝到工程的web.xml中

@2Spring

jar包

applicationContext.xml / bean.xml

<?xml version="1.0" encoding="UTF-8"?>
<!--
  - Middle tier application context definition for the image database.
  -->
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
        <!--自动扫描预装配bean  -->
        
        <context:component-scan base-package="cn.hui.oa"></context:component-scan>


</beans>

@3Hibernate

jar包，

主配置文件，映射文件

@3整合SSH
------Structs2和Spring整合

-------整合之前Structs2测试，添加action

action类

jsp页

测试的运行结果

网页显示

-------Spring整合之前测试

-------测试类

------声明bean对象，使用注解，四种方式

配置bean的作用域，多例，不写Scope为单例

不使用注解的话则在xml文件重配置声明bean

测试后报错如下：

java.lang.ExceptionInInitializerError
Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [beans.xml]; nested exception is java.lang.IllegalStateException: Context namespace element 'component-scan' and its parser class [org.springframework.context.annotation.ComponentScanBeanDefinitionParser] are only available on JDK 1.5 and higher

经查阅后是Spring和JDK版本兼容问题，后来我把所有前面导入的与spring有关jar包都删除，换成下面3.2.9的jar包后成功了

单独spring测试结果

------Structs2和Spring整合测试

-------1.在web.xml中配置SPRING用于容器对象初始化的监听器

------2.添加一个插件和两个jar包

structs.xml文件

结果展示：

Hibernate和Spring整合

目的：

@1管理SessionFactory对象，一个实例

@2声明事务管理

添加jar包

applicationContext.xml中配置加入如下

    <!-- 配置SessionFactory对象 -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <!-- 指定配置文件路径 -->
        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
        <!-- 配置c3p0数据库连接池 -->
        <property name="dataSource">
            <bean class="com.mchange.v2.c3p0.ComboPooledDataSource">
