集合 Properties 的 简单例子（Spring）

package com.ioc;

import java.util.Properties;

public class Student  {
private String name;
private int age;
Properties Pp;
public Properties getPp() {
return Pp;
}
public void setPp(Properties pp) {
Pp = pp;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}

}

package com.ioc;

import java.util.Map.Entry;
import java.util.Properties;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.ClassPathResource;

public class Test {

public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("com/ioc/beans.xml");
Student s = (Student) ac.getBean("student");

Properties pp = s.getPp();
for(Entry<Object, Object> e:pp.entrySet())
{
System.out.println(e.getKey().toString()+" "+e.getValue().toString());
}

}

}
