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;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("forumBean")
public class Forum {
	private int fid;
	private String name;
	private int displayOrder;
	public int getDisplayOrder() {
		return displayOrder;
	}
	@Value("1")
	public void setDisplayOrder(int displayOrder) {
		this.displayOrder = displayOrder;
	}
	public int getFid() {
		return fid;
	}
	@Value("1")
	public void setFid(int fid) {
		this.fid = fid;
	}
	public String getName() {
		return name;
	}
	@Value("Spring EL以注解形式")
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "{fid=>"+this.fid+",name=>"+this.name+",displayOrder=>"+this.displayOrder+"}";
	}
	
	public String getAddress(String address){
		return address;
	}
}

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

6.实体Bean ForumPost的内容如下

package com.mycompany.shequ.bean;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("forumPostBean")
public class ForumPost {
	private int pid;
	private String name;
	private Forum forum;
	private String address;
	public String getAddress() {
		return address;
	}
	@Value("#{forumBean.getAddress(‘jiangsu‘)}")//通过.调用forumBean中的getAddress方法
	public void setAddress(String address) {
		this.address = address;
	}
	public int getPid() {
		return pid;
	}
	@Value("1")
	public void setPid(int pid) {
		this.pid = pid;
	}
	public String getName() {
		return name;
	}
	@Value("#{forumBean.name}")//通过.调用forumBean中的name属性
	public void setName(String name) {
		this.name = name;
	}
	public Forum getForum() {
		return forum;
	}
	@Value("#{forumBean}")
	public void setForum(Forum forum) {
		this.forum = forum;
	}
}

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

8.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"
	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/beans
	http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
	http://www.springframework.org/schema/util
	http://www.springframework.org/schema/util/spring-util-4.0.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-4.0.xsd">
	
	<context:component-scan base-package="com.mycompany.shequ.bean"/>

</beans>

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

10.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.bean.ForumPost;


public class AppTest {
	
	@Test
	public void beanTest(){
	    ConfigurableApplicationContext context = new 
	    ClassPathXmlApplicationContext("applicationContext.xml");
		ForumPost forumPost = (ForumPost) context.getBean("forumPostBean");
		System.out.println(forumPost.getName());
		System.out.println(forumPost.getAddress());
		System.out.println(forumPost.getForum());
	}
}	

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