1. 下载并导入必须的包
需要以下jar包
1.1 从spring官网下载spring包
https://repo.spring.io/ui/native/release/org/springframework/spring/
下载spring-5.2.6.RELEASE-dist.zip,并解压获取需要的包
1.2 下载commons-logging-1.2-bin.zip
http://commons.apache.org/proper/commons-logging/download_logging.cgi
下载commons-logging-1.2-bin.zip并解压出需要的包
1.3 将包复制到idea中构建的java的基础项目中
File -> Project Structure
2. 创建简单的类实例并通过Spring进行实例化
2.1 创建user类文件(user.java)
package com.firstSpringTest.me; public class user { public void say(){ System.out.println("I am a com.firstSpringTest.me.user class"); } }
2.2 构建xml文件(ApplicationContext.xml)
创建方式:
添加<bean>
<?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.firstSpringTest.me.user"></bean> </beans>
2.3 创建测试类(SpringTest.java)
package com.firstSpringTest.me; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class springTest<sout> { public static void main(String[] args){ ApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("ApplicationContext.xml"); user user = (user) classPathXmlApplicationContext.getBean("user", user.class); user.say(); } }
运行结果如下
