一、創建項目

1.利用IntelliJ創建Maven項目
2.配置pom.xml,引入Spring

<?xml version="1.0" encoding="UTF-8"?>

4.0.0

<groupId>com.jh</groupId> <artifactId>testspring</artifactId> <version>1.0-SNAPSHOT</version><dependencies><!-- Spring Core --><!-- http://mvnrepository.com/artifact/org.springframework/spring-core --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.1.4.RELEASE</version></dependency><!-- Spring Context --><!-- http://mvnrepository.com/artifact/org.springframework/spring-context --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.1.4.RELEASE</version></dependency></dependencies>

二、編寫HelloWorld

1.編寫接口類HelloWorld

public interface HelloWorld {public void sayHello(); }

2.編寫實現類HellWorldImplOne

public class HellWorldImplOne implements HelloWorld {public void sayHello() {System.out.println("hello one");} }

3. 編寫依賴類HelloWordDependanceTest

public class HelloWordDependanceTest {private HelloWorld helloWorld;public void setHelloWorld(HelloWorld helloWorld) {this.helloWorld = helloWorld;}public HelloWorld getHelloWorld() {return this.helloWorld;}}

4.編寫測試類HelloWorldDependanceMain

public class HelloWorldDependanceMain {public static void main(String[] args){ApplicationContext context =new ClassPathXmlApplicationContext("bean.xml");HelloWordDependanceTest service =(HelloWordDependanceTest) context.getBean("helloWorldDependanceTest");HelloWorld hw= service.getHelloWorld();hw.sayHello();} }

5.編寫配置文件bean.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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><bean id="HelloWorldImplOne" class="com.jh.spring.HellWorldImplOne"></bean><bean id="helloWorldDependanceTest" class="com.jh.spring.HelloWordDependanceTest"><property name="helloWorld" ref="HelloWorldImplOne"/></bean> </beans>

6.運行測試類HelloWorldDependanceMain
