一般我們會將關於資料庫的配置屬性存放在一個獨立的properties檔案

以下是屬性檔案anyview.properties

anyview.driverClassName=com.mysql.jdbc.Driver
anyview.url=jdbc:mysql://localhost:3306/anyviewdb?useUnicode=true&characterEncoding=UTF-8
anyview.username=root
anyview.password=12345678
c3p0.acquireIncrement=3
c3p0.initialPoolSize=3
c3p0.maxIdleTime=60
c3p0.maxPoolSize=15
c3p0.minPoolSize=10
c3p0.checkoutTimeout=1000
 

<!-- 匯入資料庫配置檔案資訊 -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
    	<value>anyview.properties</value>
    </property>
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
</bean>
 

<!-- 配置dataSource -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName" value="${anyview.driverClassName}" />
	<property name="url" value="${anyview.url}" />
	<property name="username" value="${anyview.username}" />
	<property name="password" value="${anyview.password}" />
</bean>
