3.在src/main/java下创建实体Bean Forum,包名(com.mycompany.shequ.bean)如图所示
![QQ截图20170324163534.png Spring4-InitializingBean 与 DisposableBean使用_Spring4_02](https://s2.51cto.com/wyfs02/M00/8F/25/wKioL1jU2oXiBlcYAABV3xP3y1E344.png?x-oss-process=image/resize,m_fixed,w_1184)
4.实体Bean Forum的内容如下
package com.mycompany.shequ.bean;

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;
}
@Override
public 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
![QQ截图20170324163727.png Spring4-InitializingBean 与 DisposableBean使用_Initializing_03](https://s2.51cto.com/wyfs02/M00/8F/25/wKioL1jU2vbDIuITAABUiSDZlDk716.png?x-oss-process=image/resize,m_fixed,w_1184)

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
![QQ截图20170324163908.png Spring4-InitializingBean 与 DisposableBean使用_Initializing_04](https://s2.51cto.com/wyfs02/M01/8F/27/wKiom1jU21qBVESdAABT42sl9us542.png?x-oss-process=image/resize,m_fixed,w_1184)
8.接口IForumService的实现类ForumServiceImpl的内容如下
package com.mycompany.shequ.service.impl;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;
import com.mycompany.shequ.bean.Forum;
import com.mycompany.shequ.service.IForumService;
public class ForumServiceImpl implements IForumService, InitializingBean,
DisposableBean {
public void destroy() throws Exception {
System.out.println("destroy被调用");
}
public void afterPropertiesSet() throws Exception {
System.out.println("afterPropertiesSet被调用");
}
public Forum findForumById(int fid) {
Forum forum = new Forum();
forum.setName("InitializingBean与DisposableBean");
return forum;
}
}
9.在src/main/resource下创建bean的配置文件spring-bean.xml,如图所示
![QQ截图20170324164030.png Spring4-InitializingBean 与 DisposableBean使用_Bean_05](https://s2.51cto.com/wyfs02/M02/8F/27/wKiom1jU267QGeQ9AABKPUB-dEA433.png?x-oss-process=image/resize,m_fixed,w_1184)

<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
![QQ截图20170324164244.png Spring4-InitializingBean 与 DisposableBean使用_Spring4_07](https://s2.51cto.com/wyfs02/M01/8F/27/wKiom1jU3DPwfq9nAABJPTqrNcc707.png?x-oss-process=image/resize,m_fixed,w_1184)
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 {
@Test
public 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
