首先在配置文件中配置PropertyPlaceholderConfigurer
单个配置文件: <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations" value="classpath:com/foo/jdbc.properties"/> </bean> 多个配置文件: <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:jdbc.properties</value> <value>classpath:config.properties</value> </list></property> </bean> 然后在需要的地方直接以下方式引用: <property name="url" value="${jdbc.url}"/>
