Spring最基础的项目搭建与配置

本实例主要记录在java project中配置spring最基本的使用

1.下载spring，本实例用的是最新版4.3.3

spring 官网下载，下载地址：http://repo.spring.io/release/org/springframework/spring/

2.创建java project, 项目名Spring_01

3.引入所需jar文件，导入spring-framework-4.3.3.RELEASE-dist\spring-framework-4.3.3.RELEASE\libs下所有jar, 还有commons-logging-1.1.3.jar（在struts下载包中，否则会报错）

4.创建一个动物interface, 取名叫Animal

package com.bobo.app;

public interface Animal {
public void call();
public void walk();
}

5.创建Dog class， 实现Animal接口，并实现接口中的两个方法

package com.bobo.app;

public class Dog implements Animal {

@Override
public void call() {
System.out.println("汪汪叫");
}

@Override
public void walk() {
System.out.println("四条腿走路");
}

}

6.创建Duck class， 实现Animal接口，并实现接口中的两个方法

package com.bobo.app;

public class Duck implements Animal {

@Override
public void call() {
System.out.println("呱呱叫");
}

@Override
public void walk() {
System.out.println("两条腿走路");
}

}

7.在src下创建spring配置文件applicationContext.xml， 配置两个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"
xmlns:oxm="http://www.springframework.org/schema/oxm"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm.xsd"> 
<bean id="duckBean" class="com.bobo.app.Duck"> </bean>
<bean id="dogBean" class="com.bobo.app.Dog"> </bean>
</beans>

8.创建测试类Test

package com.bobo.app;

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

public class Test {

public static void main(String[] args) {
ApplicationContext ac = new FileSystemXmlApplicationContext("src/applicationContext.xml");

Dog dog = (Dog) ac.getBean("dogBean");

Duck duck = (Duck) ac.getBean("duckBean");

dog.call();
dog.walk();

duck.call();
duck.walk();
}

}

9.测试结果

汪汪叫

四条腿走路

呱呱叫

两条腿走路
