Spring框架学习笔记（1）—

1、创建一个新的项目，并添加Spring框架

2、创建HelloWorld.java

package com.broadtext.beans.helloworld;

public class HelloWorld {

    private String name;

    public HelloWorld() {

    }

    @Override

    public String toString() {

        return "HelloWorld [name=" + name + "]";

    }

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

}

3、修改applicationContext.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"

    xmlns:p="http://www.springframework.org/schema/p"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">

    <bean id="helloWorld" class="com.broadtext.beans.helloworld.HelloWorld">

        <property name="name" value="hjj"></property>

    </bean>

</beans>

这时候HelloWorld.java文件上会多出'S'标记

4、添加Main.java和Main方法测试HelloWorld bean

package com.broadtext.beans.helloworld;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

    public static void main(String[] args) {

        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

        HelloWorld helloWorld = ctx.getBean(HelloWorld.class);

        System.out.println(helloWorld);

    }

}

5、运行，看看控制台打印的HelloWorld
