@Component

public class BaseConfigPath { private static final String configPath = System.getProperty("user.home")+"/code/config";public String getConfigPath() { return configPath;}}

根据配置文件路径解析properties

<context:property-placeholder location="file:#{baseConfigPath.configPath}/jdbc.properties"/>

获取properties的属性值

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!-- 配置连接池属性 --><property name="driverClass" value="${jdbc.driverClassName}"></property><property name="jdbcUrl" value="${jdbc.url}"></property><property name="user" value="${jdbc.username}"></property><property name="password" value="${jdbc.password}"></property>
