ssm--springmvc3

第一步:保证业务层(Service)和持久层(Dao)在web项目下运行
配置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"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--告知spring容器,需要扫描注解配置的包-->
    <context:component-scan base-package="com.baidu">
        <!--制定扫描规则,排除过滤带有@Controller注解的类-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter>
    </context:component-scan>
</beans>


第二步:保证表现层(Controller)在web项目下运行
配置web.xml
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
  <display-name>Archetype Created Web Application</display-name>
    <!--配置servlet-->
    <servlet>
        <!--配置前端控制器-->
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!----初始化配置,加载springmvc的配置文件-->
		<init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--配置创建servlet对象的时机-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!--配置前端控制器的拦截方式-->
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    
    <!--配置filter-->
    <filter>
        <!--解决中文乱码的过滤器-->
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <!--初始化参数,配置过滤器的属性值-->
        <init-param>
            <param-name>Encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
         <init-param>	
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <!--配置过滤器的拦截方式-->
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

配置springmvc.xml
 <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
  
    <!--告知spring容器,需要扫描注解配置的包-->
    <context:component-scan base-package="com.baidu">
        <!--制定扫描规则,包含过滤@Controller注解的java类-->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller">
    </context:component-scan>
        
     <!--配置内部资源视图解析器对象-->
     <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <!--使用set方法注入prefix,suffix属性-->
         <property name="prefix" value="/WEB-INF/pages/"></property>
         <property name="suffix" value=".jsp"></property>
     </bean>
      <!--配置处理器映射器和处理器适配器,可以省略,会默认配置-->  
       <mvc:annotation-driven></mvc:annotation-driven>
</beans>
    
    
第三步:整合spring和springmvc
配置web.xml
    ...
    <!--配置spring容器提供的环境加载监听器,用于开启服务器时加载applicationContext.xml,但是这个监听器默认只能读取WEB-INF目录下的applicationCOntext.xml-->
    <listener>
        <listener-calss>
            org.springframework.web.context.ContextLoaderListener
        </listener-calss>
    </listener>
    <!--手动指定applicationContext.xml的位置-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    ...
    <servlet>
    </servlet>
    
第四步:保证MyBatis在web项目下运行
    a.配置SqlMapperConfig.xml
    b.配置映射配置文件
	SqlSessionFactoryBean implements FactoryBean
第五步:整合spring和Mybatis,在applicationContext.xml中配置
    a.<!--spring接管SqlSession工厂,配置SqlSessionFactoryBean对象-->
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--使用set方法注入dataSource属性-->
        <property name="dataSource" ref="dataSource"></property>
        <!--如果需要用到sqlMapConfig.xml中的配置,注入configLocation的属性-->
        <property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
        <!--如果需要使用延迟加载,二级缓存再配置也行-->
    </bean>
   <!--加载properties配置文件-->
    <context:property-placeholder location="classpath:jabcConfig.properties"></context:property-placeholder>
    <!--配置数据库连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
         <!--使用set方法注入属性-->
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    b.<!--配置mapper扫描器对象-->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--使用set方法注入basePackage属性-->
        <property name="basePackage" value="com.baidu.dao"></property>
    </bean>
<!--在service层配置事务传播------------------------------------->
    c.<!--配置spring事务管理器对象-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager">
        <tx:attributes>
            <!--配置事务通知的方法-->
            <tx:method name="find*" propagation="SUPPORTS" read-only="true"></tx:method>
            <tx:method name="*" propagation="REQUIRED" read-only="false"></tx:method>
        </tx:attributes>
    </tx:advice>
    <!--配置AOP-->
    <aop:config>
        <!--配置切入点表达式-->
        <aop:pointcut id="pc" expression="execution(* com.baidu.service.impl.*.*(..))"></aop:pointcut>
        <!--建立切入点跟通知间的对应关系-->
        <aop:advisor pointcut-ref="pc" advice-ref="txAdvice">
        </aop:advisor>
    </aop:config>
