1.创建Maven项目,项目名称springdemo42,如图所示

2.配置Maven,修改项目中的pom.xml文件,修改内容如下

<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>1.0.0</modelVersion><groupId>shequ</groupId><artifactId>springdemo13</artifactId><version>0.0.1-SNAPSHOT</version><properties><java.version>1.7</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding></properties><repositories><repository><id>codelds</id><url>https://code.lds.org/nexus/content/groups/main-repo</url></repository></repositories><dependencies><dependency><groupId>javax.annotation</groupId><artifactId>jsr250-api</artifactId><version>1.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.10</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.34</version></dependency></dependencies><build/>
</project>

3.在src/main/java下创建实体Bean Forum,包名(com.mycompany.shequ.bean)如图所示

4.实体Bean Forum的内容如下

package com.mycompany.shequ.bean;public class Forum {private int fid;private String name;private int displayOrder;public int getDisplayOrder() {return displayOrder;}public void setDisplayOrder(int displayOrder) {this.displayOrder = displayOrder;}public int getFid() {return fid;}public void setFid(int fid) {this.fid = fid;}public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic String toString() {return "{fid=>"+this.fid+",name=>"+this.name+",displayOrder=>"+this.displayOrder+"}";}
}

5.在src/main/java下创建接口IForumService,包名(com.mycompany.shequ.service)如图所示

6.接口IForumService的内容如下

package com.mycompany.shequ.service;import com.mycompany.shequ.bean.Forum;public interface IForumService {public Forum findForumById(int fid);
}

7.在src/main/java下创建接口IForumService的实现类ForumServiceImpl,包名(com.mycompany.shequ.service.impl)如图所示

8.接口IForumService的实现类ForumServiceImpl的内容如下

package com.mycompany.shequ.service.impl;import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;import com.mycompany.shequ.bean.Forum;
import com.mycompany.shequ.service.IForumService;public class ForumServiceImpl implements IForumService {@PreDestroypublic void destroyMethod(){System.out.println("destroy-method");}@PostConstructpublic void initMethod(){System.out.println("init-method");}public Forum findForumById(int fid) {Forum forum = new Forum();forum.setName("init-method 与 destroy-method");return forum;}
}

9.在src/main/resource下创建bean的配置文件spring-bean.xml,如图所示

10.配置文件spring-bean.xml的内容如下

<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"xmlns:context="http://www.springframework.org/schema/context"xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsd"><context:annotation-config /><bean id="forumservicebean" class="com.mycompany.shequ.service.impl.ForumServiceImpl"></bean>
</beans>

11.在src/main/resource下创建核心的配置文件applicationContext.xml,如图所示

12.核心的配置文件applicationContext.xml的内容如下

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsd"><import resource="bean/spring-bean.xml"/></beans>

13.在src/test/java下创建测试文件AppTest,包名(com.mycompany.shequ.test)如图所示

14.测试文件AppTest的内容如下

package com.mycompany.shequ.test;import org.junit.Test;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import com.mycompany.shequ.service.IForumService;public class AppTest {@Testpublic void beanTest(){ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");IForumService forumService = (IForumService)context.getBean("forumservicebean");System.out.println(forumService.findForumById(1));context.close();}
}   

15.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
