创建普通类，在这个类创建普通方法
public class User{
public void add(){
System.out.println("添加...");
}
}
创建Spring配置文件，在配置文件配置创建对象
配置文件为xml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对象创建 --> <bean id="user" class="com.ye.User"> </bean> </beans>
进行测试代码编写
package com.ye;
import javafx.application.Application;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**

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