spring5 入门第一课，创建对象 01

1.项目结构

 

2.步骤

2.1 创建User

package com.cj.spring5;

public class User {
    public void add(){
        System.out.println("add...");
    }
}

2.2 创建xml

<?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="user" class="com.cj.spring5.User"></bean>
</beans>

2.3 创建Test

package com.cj.spring5.testdemo;

import com.cj.spring5.User;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring5 {

    @Test
    public void test1(){
        //获取xml
        ClassPathXmlApplicationContext xml = new ClassPathXmlApplicationContext("bean1.xml");


        //获取对象
        User user = xml.getBean("user", User.class);
        System.out.println(user);
        //调用
        user.add();
    }
}
