使用Intellij编写Spring Hello World

编写基于Intellij2016.3与Java SDK1.8

下载Spring最新jar包：

http://repo.spring.io/release/org/springframework/spring

和Spring依赖的日志组件包

http://commons.apache.org/proper/commons-logging/

1、新建一个Module

上图如果选择不完整的话，可以如下添加依赖添加确实的jar包。

2、添加依赖

经测试，一个简单的HelloWorld程序也需要依赖如下5个包：

3、编写测试文件

HelloWorld.java

package com.xiya;

/**

 * Created by N3verL4nd on 2017/3/4.

 */

public class HelloWorld {

    private String message;

    public void setMessage(String message) {

        this.message = message;

    }

    public String getMessage() {

        return message;

    }

}

MainApp.java

package com.xiya;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**

 * Created by N3verL4nd on 2017/3/4.

 */

public class MainApp {

    public static void main(String[] args) {

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

        HelloWorld test = (HelloWorld) applicationContext.getBean("HelloWorld");

        System.out.println(test.getMessage());

    }

}

4、编写beans配置文件(src目录下)

<?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="HelloWorld" class="com.xiya.HelloWorld">

        <property name="message" value="Spring Hello World!" />

    </bean>

</beans>

一下对程序运行并没有影响，它的作用估计是方便查找xml文件之间的关系吧

运行，报错：

原因是少加入commons-logging-1.2包

添加方法同上。
