Spring的配置

 

1、

package com.helen.bean;

public class Student {
    private int stuid;
    private String name;
    private String mess;

    public int getStuid() {
        return stuid;
    }

    public void setStuid(int stuid) {
        this.stuid = stuid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMess() {
        return mess;
    }

    public void setMess(String mess) {
        this.mess = mess;
    }

    @Override
    public String toString() {
        return "Student [stuid=" + stuid + ", name=" + name + ", mess=" + mess
                + "]";
    }

}

beans.xml:

<bean id="stu" class="com.helen.bean.Student" scope="prototype">
        <property name="mess" value="Hello World!!!" />
    </bean>

 

Test.java:

package com.helen.bean;



import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

    public static void main(String[] args) {
    
        ApplicationContext   context = new ClassPathXmlApplicationContext("Beans.xml");
        Student stu=(Student)context.getBean("stu");
        Student stu1=(Student)context.getBean("stu");
        System.out.println("stu==stu1:"+(stu==stu1));
        stu.setName("helen");
        stu.setStuid(15);
        System.out.println("Infor:"+stu.getStuid()+" "+stu.getName()+" "+stu.getMess());
}
}

 

stu==stu1:true
Infor:15 helen Hello World!!!
