本文讲解：在maven构建的普通jar工程下，使用xml配置方式启动spring容器实现简单bean的装配

1.工具

maven

spring framwork 4.2.4.RELEASE

2.使用eclipse创建maven工程

新建工程：

选择maven工程：

 

创建工程后如下：

2：引入spring framework

使用pom文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.jackletter</groupId> <artifactId>hellospring</artifactId> <version>0.0.1-SNAPSHOT</version> <name>this is name</name> <description>this is desc</description> <properties> <spring.version>4.2.4.RELEASE</spring.version> </properties> <dependencies> <!-- Spring Core --> <!-- http://mvnrepository.com/artifact/org.springframework/spring-core --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <!-- Spring Context --> <!-- http://mvnrepository.com/artifact/org.springframework/spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> </dependencies> </project>

 

3.java代码

HelloProgram

package hellospring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import hellospring.service.HelloWorld; import hellospring.service.HelloWorldService; public class HelloProgram { public static void main(String[] args) { @SuppressWarnings("resource") ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml"); HelloWorldService service = (HelloWorldService) context.getBean("helloWorldService"); HelloWorld hw = service.getHelloWorld(); hw.sayHello(); } }

HelloWorld

 

package hellospring.service; public interface HelloWorld { public void sayHello(); }

HelloWorldService

package hellospring.service; public class HelloWorldService { private HelloWorld helloWorld; public HelloWorldService() { } public void setHelloWorld(HelloWorld helloWorld) { this.helloWorld = helloWorld; } public HelloWorld getHelloWorld() { return this.helloWorld; } }

 

StrutsHelloWorld

package hellospring.service.impl; import hellospring.service.HelloWorld; public class StrutsHelloWorld implements HelloWorld { @Override public void sayHello() { System.out.println("Struts Say Hello!!"); } }

SpringHelloWorld

package hellospring.service.impl; import hellospring.service.HelloWorld; public class SpringHelloWorld implements HelloWorld { @Override public void sayHello() { System.out.println("Spring Say Hello!!"); } }

4.配置文件beans.xml (hellospring\src\main\resources\beans.xml)

<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="springHelloWorld" class="hellospring.service.impl.SpringHelloWorld"></bean> <bean id="strutsHelloWorld" class="hellospring.service.impl.StrutsHelloWorld"></bean> <bean id="helloWorldService" class="hellospring.service.HelloWorldService"> <property name="helloWorld" ref="springHelloWorld" /> </bean> </beans>

5.运行
