Spring2+struts2.3+ibatis框架整合

这几天一直想着搭建一个简单的SSI框架，下面就把步骤一步一步写下来，相互学习交流！

1.新建Web Project工程

2.增加struts2的jar包

3.然后配置web.xml中的struts过滤器，启动应该是不报错误。

<filter>  
  	<filter-name>struts2</filter-name>  
  	<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>  
  </filter>  
  <!-- 让struts定义的核心filter拦截所有请求 -->  
  <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>

4.增加Spring的jar包

5.然后配置webl.xml中的Spring配置，然后在src目录下建一个applicationContext.xml，启动应该不会报错误

<!-- 用于配置读取applicationContext.xml -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<!-- 配置spring监听器 -->    
    <listener>    
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    
    </listener>

 6.基本的配置完毕后，下面我们就要做数据源饿配置，我用的是oracle数据库，c3p0连接池

(1).在src目录下建立一个c3p0连接池文件：c3p0.properties

datasource.type=oracle
datasource.driverClassName=oracle.jdbc.driver.OracleDriver
datasource.url=jdbc:oracle:thin:@localhost:1521:orcl
datasource.username=test
datasource.password=test
c3p0.acquireIncrement=3
c3p0.initialPoolSize=3
c3p0.idleConnectionTestPeriod=900
c3p0.minPoolSize=2
c3p0.maxPoolSize=50
c3p0.maxStatements=100
c3p0.numHelperThreads=10
c3p0.maxIdleTime=600
c3p0.testConnectionOnCheckout=true
c3p0.preferredTestQuery=select sysdate from dual
c3p0.dialect=org.hibernate.dialect.Oracle9Dialect

(2).在applicationContext.xml文件中配置数据源

 <bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:c3p0.properties</value>
			</list>
		</property>
	</bean>
	<!--定义数据源-->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close" dependency-check="none">
		<property name="driverClass">
			<value>${datasource.driverClassName}</value>
		</property>
		<property name="jdbcUrl">
			<value>${datasource.url}</value>
		</property>
		<property name="user">
			<value>${datasource.username}</value>
		</property>
		<property name="password">
			<value>${datasource.password}</value>
		</property>
		<property name="acquireIncrement">
			<value>${c3p0.acquireIncrement}</value>
		</property>
		<property name="initialPoolSize">
			<value>${c3p0.initialPoolSize}</value>
		</property>
		<property name="minPoolSize">
			<value>${c3p0.minPoolSize}</value>
		</property>
		<property name="maxPoolSize">
			<value>${c3p0.maxPoolSize}</value>
		</property>
		<property name="maxIdleTime">
			<value>${c3p0.maxIdleTime}</value>
		</property>
		<property name="idleConnectionTestPeriod">
			<value>${c3p0.idleConnectionTestPeriod}</value>
		</property>
		<property name="maxStatements">
			<value>${c3p0.maxStatements}</value>
		</property>
		<property name="numHelperThreads">
			<value>${c3p0.numHelperThreads}</value>
		</property>
		<property name="testConnectionOnCheckout">
			<value>${c3p0.testConnectionOnCheckout}</value>
		</property>
		<property name="preferredTestQuery">
			<value>${c3p0.preferredTestQuery}</value>
		</property>
	</bean>

(3).此时启动可能要报错，现在需要引入两个jar包,然后再次启动则没有错误

7.下面配置struts文件

<constant name="struts.objectFactory" value="spring"></constant>    
     <!-- 所有的action都应该放在对应的package下 -->  
     <package name="riyun" extends="struts-default">  
        <action name="login" class="loginAction">  
            <!-- 定义逻辑视图和物理资源之间的映射 -->  
            <result name="success">/success.jsp</result>  
            <result name="error">/error.jsp</result>  
        </action>  
     </package>

8.然后建一个实体类和登录action

9.下面就开始加入mybatis包用来持久化类了
