Spring中的Bean配置

package com.example;

public class SimpleBean {
    private father fth;

    public SimpleBean(father fth) {
        this.fth = fth;
    }

    public void send(){
        System.out.println("i am from SimpleBean");
        fth.sing();
    }
}

package com.example;

public class father {
    private int count;

    public void setCount(int count) {
        this.count = count;
    }

    public void sing(){
        System.out.println("i am from father:"+count);
        count++;
    }
}

实例化Spring IOC容器是简单快捷的，提供给Application Context的路径就是实际的资源字符串，使资源能从各种资源中装备元数据配置，例如本地系统，JAVA classpath等。

package com.example;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class min {
    public static void main(String[] args) {
        //文件的地址
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-ioc.xml");
        //实例化那个文件中的对象

        SimpleBean bean = context.getBean(SimpleBean.class);
        father bean2 = context.getBean(father.class);
        bean.send();
        bean2.sing();
        context.close();

    }
}
