<context:property-placeholder location="p.properties"/> <bean id="p" class="com.Person">
<property name="name" value="${name}"/>
</bean>
工程 resource下新建一个 p.properties文件,里面内容为:
name=hahadaxiao
使用:
public static void main(String[] args){
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("a.xml");
Person p = context.getBean("p",Person.class);
System.out.println(p.name);
}
打印:
hahadaxiao
若有多个properties文件,则用 *号通配符,或者用逗号分隔
<context:property-placeholder location="*.properties"/>
<context:property-placeholder location="p.properties,pbp.properties"/>
