1. 下载与eclipse版本对应的springsource-tool-suite包

官网下载地址：http://spring.io/tools/sts/all

2. 安装springsource-tool-suite

3. 安装完成后重启eclipse，出现下面表示安装成功

4. 下载Spring项目所需的jar包

5.新建java项目，新建lib文件夹将下面的五个jar包导入工程

6.新建HelloWorld类

package com.njupt.spring;

public class HelloWorld {
    private String name;

    public String getName() {
        return name;
    }

    public void setName2(String name) {
        this.name = name;
    }
    public void sayHello() {
        System.out.println("Hello World!");
    }
    
}

7.新建Spring的配制文件

<?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">
    <!-- 配制bean -->
    <bean id="helloWorld" class="com.njupt.spring.HelloWorld">
        <property name="name2" value="Spring"></property>
    </bean>
</beans>

8.在main函数中使用该javaBean

package com.njupt.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
    public static void main( String [] args ) {
        //1.创建Spring的IOC容器对象
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
        //2.从IOC容器中获取bean实例
        HelloWorld helloWorld = (HelloWorld)ctx.getBean("helloWorld");
        //3.调用bean的方法
        helloWorld.sayHello();
    }
}
