挖spring的代码发现的
spring自带读取属性格式的方法 用到两个不常用的类 PropertiesBeanDefinitionReader ,GenericApplicationContext /*

package demo;
import java.util.ResourceBundle;
import org.springframework.beans.factory.support.PropertiesBeanDefinitionReader;
import org.springframework.context.support.GenericApplicationContext;
/**

* @version $Id$
*/
public class PropertyBDDemo {
public static void main(String[] args); {
GenericApplicationContext ctx = new GenericApplicationContext();;
PropertiesBeanDefinitionReader pdb = new PropertiesBeanDefinitionReader(
ctx);;
ResourceBundle rb = ResourceBundle.getBundle("bd");;
pdb.registerBeanDefinitions(rb);;
System.out.println(((World);ctx.getBean("world"););.getHello();.getI(););;
}
}
bd.properties内容 hello.class=demo.Hello hello.i=1 world.class=demo.World world.hello(ref);=hello 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。

你这个忒麻烦了,有现成的,spring文档41页.
引用 The PropertyPlaceholderConfigurer has already been described, as used with a BeanFactory. It is worth mentioning here though, that it is generally more convenient to use it with an ApplicationContext, since the context will automatically recognize and apply any bean factory post-processors, such as this one, when they are simply deployed into it like any other bean. There is no need for a manual step to execute it. <!-- property placeholder post-processor --> <bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location"><value>jdbc.properties</value></property> </bean> 不用在程序里写 jdbc.properties的位置是按classpath来的,我想把配置文件放到classpath外面去,不晓得怎么搞,哪位知道? |

求人不如求己,暴力方法解决,你不是要resource吗?我给你个FileSystemResource.
什么?没setPath()?继续暴力,给构造参数........
<!--about config-->
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location"><ref bean="configResource"/></property>
</bean>
<bean id="configResource" class="org.springframework.core.io.FileSystemResource" singleton="false">
<constructor-arg type="java.lang.String"><value>conf/jdbc.properties</value></constructor-arg>
</bean>
