　　在配置文件里配置 Bean 时, 有时需要在 Bean 的配置里混入系统部署的细节信息(例如: 文件路径, 数据源配置信息等). 而这些部署细节实际上需要和 Bean 配置相分离
Spring 提供了一个 PropertyPlaceholderConfigurer 的 BeanFactory 后置处理器, 这个处理器允许用户将 Bean 配置的部分内容外移到属性文件中. 可以在 Bean 配置文件里使用形式为 ${var} 的变量, PropertyPlaceholderConfigurer 从属性文件里加载属性, 并使用这些属性来替换变量.
Spring 还允许在属性文件中使用 ${propName}，以实现属性之间的相互引用。

一个原始的数据库源配置

1.引入类库-c3p0 和 mysql:

        <dependency>
            <groupId>com.mchange</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.5.1</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.35</version>
        </dependency>

2.配置ComboPooledDataSource数据源bean实例:

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="root"></property>
        <property name="password" value="root"></property>
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/retrieval?characterEncoding=UTF-8"></property>
    </bean>

3.测试：

public class App {

    @SuppressWarnings("resource")
    public static void main(String[] args) throws SQLException {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-properties.xml");
        DataSource ds = ctx.getBean("dataSource",DataSource.class);
        System.out.println(ds.getConnection());
    }

}

结果:

从外部属性文件中读取

1.创建一个属性文件-db.properties

user=root
password=root
driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://127.0.0.1:3306/retrieval?characterEncoding=UTF-8

2.注册 PropertyPlaceholderConfigurer.使其可以从属性文件中加载属性.

首先引入命名空间context.

    <!-- 导入属性文件 -->
    <context:property-placeholder location="classpath:db.properties"/>

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 使用外部属性文件中的属性 -->
        <property name="user" value="${user}"></property>
        <property name="password" value="${password}"></property>
        <property name="driverClass" value="${driverClass}"></property>
        <property name="jdbcUrl" value="${jdbcUrl}"></property>
    </bean>

　　这样就完成部署了.

　　这样做的好处:修改外部属性文件的成本要比修改Spring 配置文件的成本要低的多.
