JavaEE笔记（八）

第一个Spring

Student（学生） bean

package com.my.bean;

import java.io.Serializable;

public class Student implements Serializable{

    private static final long serialVersionUID = 1L;

    private String name;

    private MyClass myClass;

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public MyClass getMyClass() {

        return myClass;

    }

    public void setMyClass(MyClass myClass) {

        this.myClass = myClass;

    }

}

Class（班级） bean

package com.my.bean;

import java.io.Serializable;

public class MyClass implements Serializable{

    private static final long serialVersionUID = 1L;

    private String name;

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

}

需要导入的jar包

beans配置文件

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

           http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="stu" class="com.my.bean.Student">

<property name="name" value="小明"/>

<property name="myClass" ref="cls"/>

</bean>

<bean id="cls" class="com.my.bean.MyClass">

<property name="name" value="班级一"/>

</bean>

</beans>

获取已经配置的Student类

package com.my.test;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.my.bean.Student;

public class Test {

    /**

     * @param args

     */

    public static void main(String[] args) {

        ApplicationContext context =

                new ClassPathXmlApplicationContext("beans.xml");

        //获取已经配置的Stu

        Student stu = context.getBean("stu",Student.class);

        System.err.println(stu.getName());

    }

}
