拆分Spring配置文件

把一个applicationContext.xml拆分（还可以再分出action部分和tx事务部分）

　　1、dao部分

<!-- 配置DAO -->
    <bean id="employeeDao" class="cn.bdqn.jboa.dao.hibimpl.EmployeeDaoHibImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <bean id="claimVoucherDao" class="cn.bdqn.jboa.dao.hibimpl.ClaimVoucherDaoHibImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <bean id="claimVoucherDetailDao" class="cn.bdqn.jboa.dao.hibimpl.ClaimVoucherDetailDaoHibImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

　　2、service部分

<!-- 配置业务层 -->
    <bean id="employeeService" class="cn.bdqn.jboa.service.impl.EmployeeServiceImpl">
        <property name="employeeDao" ref="employeeDao"></property>
    </bean>
    <bean id="claimVoucherService" class="cn.bdqn.jboa.service.impl.ClaimVoucherServiceImpl">
        <property name="claimVoucherDao" ref="claimVoucherDao" />
        <property name="claimVoucherDetailDao" ref="claimVoucherDetailDao" />
    </bean>

　　3、基本类

<!-- 通过<import resource="xxx.xml">方式注入多个配置文件 -->
    <!--
    <import resource="applicationContext-dao.xml" />
    <import resource="applicationContext-service.xml" />
    -->
    
    <!-- 定义dbcp数据源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <!-- 指定JDBC驱动类 -->
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver">
        </property>
        <!-- 提供连接数据库的URL地址 -->
        <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl">
        </property>
        <!-- 提供连接数据库的用户名和密码 -->
        <property name="username" value="bdqn"></property>
        <property name="password" value="bdqn"></property>
    </bean>
    <!-- 定义SessionFactory Bean -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <!-- 为LocalSessionFactoryBean注入定义好的数据源 -->
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <!-- 添加Hibernate配置参数 -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.OracleDialect
                </prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
        <!-- 添加对象关系映射文件 -->
        <!-- <property name="mappingResources">
            <list>
                <value>cn/bdqn/jboa/entity/ClaimVoucher.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/ClaimVoucherDetail.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/Employee.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/CheckResult.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/Position.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/Department.hbm.xml</value>
                <value>cn/bdqn/jboa/entity/Dictionary.hbm.xml</value>
            </list>
        </property> -->
        <property name="mappingDirectoryLocations">
            <list>
                <value>classpath:cn/bdqn/jboa/entity/</value>
            </list>
        </property>
    </bean>
    
    <!-- 定义事务管理器 -->
    <bean id="txManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true" />
            <tx:method name="search*" read-only="true" />
            <tx:method name="query*" read-only="true" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="del*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="do*" propagation="REQUIRED" />
            <tx:method name="*" propagation="REQUIRED" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <aop:config>
        <!-- 定义切入点 -->
        <aop:pointcut id="serviceMethod"
            expression="execution(* cn.bdqn.jboa.service.*.*(..))" />
        <!-- 将事务通知与切入点组合 -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod" />
    </aop:config>

    <!-- 控制层 (id为struts.xml中的class) 以下每个bean必须都要增加scope="prototype"属性 -->
    <!-- <bean id="userAction" class="cn.bdqn.jboa.action.UserAction"
        scope="prototype">
        <property name="employeeService" ref="employeeService"></property>
    </bean> -->
