入门案例

1.下载spring5:https://repo.spring.io/ui/native/libs-release/org/springframework/spring

2. 打开IDEA，创建普通工程

3.导入基本jar包

 

 4.创建普通类

package com.as.sping5;

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

5.创建xml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">
<!--  配置User  -->
    <bean id="user" class="com.as.sping5.User"></bean>
</beans>

6.进行测试

package test;

import com.as.sping5.User;
import javafx.application.Application;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {

    @Test
    public void test1() {
        //1.加载Spring配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("bean1.xml");
        //2.获取配置创建的对象
        User user = ac.getBean("user", User.class);
        System.out.println(user);
        user.add();
    }
}
