上篇中整合了properties于Spring Config配置文件中读取，那么接下来也可以将之前的的service和dao一起整合，整合后的完整Spring Config配置文件则如：
<?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"
       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
">
    <context:property-placeholder location="jdbc.properties"/>
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <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>
    <bean id="buser1" class="com.User">
        <property name="name" value="user1"/>
        <property name="addr" value="shenzhen"/>
    </bean>
    <bean id="buser2" class="com.User">
        <property name="name" value="user2"/>
        <property name="addr" value="shanxi"/>
    </bean>
    <bean id="userDao" class="com.dao.impl.UserDaoImpl">
        <property name="name" value="zhangsan"/>
        <property name="age" value="18"/>
        <property name="strList">
            <list>
                <value>a</value>
                <value>b</value>
                <value>c</value>
            </list>
        </property>
        <property name="userMap">
            <map>
                <entry key="mp_user1" value-ref="buser1"/>
                <entry key="mp_user2" value-ref="buser2"/>
            </map>
        </property>
        <property name="properties">
            <props>
                <prop key="key1">val1</prop>
                <prop key="key2">val2</prop>
            </props>
        </property>
    </bean>
    <bean id="userService" class="com.service.impl.UserServiceImplement">
        <constructor-arg name="userDao" ref="userDao"/>
    </bean>
</beans>
然后模拟一个web的入口方法main方法则如：
package com.web;

import com.service.UserService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Index2 {
    public static void main(String[] args) {
        ApplicationContext app=new ClassPathXmlApplicationContext("JDBCApplicationContext.xml");
        UserService userService=  app.getBean(UserService.class);
        userService.save();
    }
}
