测试代码：
主要使用DefaultListablebeanfactory和PropertiesBeanDefinitionReader这两个核心类
package
ch2;
import java.io.File;
import java.io.FileInputStream;
import java.util.Properties;
import org.springframework.beans.factory.beanfactory;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.DefaultListablebeanfactory;
import org.springframework.beans.factory.support.PropertiesBeanDefinitionReader;
public class TestSpring ... {
publicstaticvoidmain(Stringargs[])throwsException...{
//获取beanfactory
beanfactoryfactory=(beanfactory)getbeanfactory();
Studentstu=(Student)factory.getBean("student");//这里只获取student对象,student对象中的course对象在properties文件中进行注入
System.out.println(stu.getStuName()+"'scourseis"+stu.getStuCourse().getCourseName());
}
publicstaticBeanDefinitionRegistrygetbeanfactory()...{
//获取beanfactory
DefaultListablebeanfactoryfactory=newDefaultListablebeanfactory();
//创建一个definitionreader
PropertiesBeanDefinitionReaderrd=newPropertiesBeanDefinitionReader(factory);
Propertiesprops=newProperties();
try...{
Stringrealpath="";
//加载配置项
realpath=System.getProperty("user.dir")+File.separator+"src"+File.separator+"ch2"+File.separator+"bean_zh_CN.properties";
props.load(newFileInputStream(realpath));
}catch(Exceptione)...{
e.printStackTrace();
returnnull;
}
rd.registerBeanDefinitions(props);
returnfactory;
}
}
import java.io.File;

System.out.println(stu.getStuName()+"'scourseis"+stu.getStuCourse().getCourseName());
}
publicstaticBeanDefinitionRegistrygetbeanfactory()...{
//获取beanfactory
DefaultListablebeanfactoryfactory=newDefaultListablebeanfactory();
//创建一个definitionreader
PropertiesBeanDefinitionReaderrd=newPropertiesBeanDefinitionReader(factory);

props.load(newFileInputStream(realpath));
}catch(Exceptione)...{

returnnull;
}
rd.registerBeanDefinitions(props);
returnfactory;
}
}
运行结果：
gaoxiang 's course is shuxue 正如我们锁期望的那样
