一、开发前的准备
两个开发包spring-framework-3.1.1.RELEASE-with-docs.zip和commons-logging-1.2-bin.zip，将它们解压，然后把Spring开发包下dist目录的所有包和commons-logging包下的commons-logging-1.1.1.jar复制到名为Spring3.1.1的文件夹下。那么Spring开发所需要的包就组织好了。
二、建立项目，导入包
在项目节点上右键，Build Path/ADD Libraries/USER Libraries/new/输入包名Spring3.1.1/OK/ADD JARS/选中准备好的包/OK。此外引入JUnit4方便程序测试。
三、添加文件
person接口Person.Java：
package com.bean;
public interface Person{
public void Speak();
}
AmericanImpl.java：
package com.bean;
public class AmericanImpl implements Person{
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public void Speak() {
// TODO Auto-generated method stub
System.out.println("I'm American,My name is "+this.name+",I'm "+this.age+" years old!");
}
}
ChineseImpl.java：
package com.bean;
public class ChineseImpl implements Person{
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public void Speak() {
// TODO Auto-generated method stub
System.out.println("I'm Chinese,My name is "+this.name+",I'm "+this.age+" years old!");
}
}
配置文件applicationContext.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"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<bean id="chinese" class="com.bean.ChineseImpl">
<property name="name">
<value>小明</value>
</property>
<property name="age">
<value>10</value>
</property>
</bean>
<bean id="american" class="com.bean.AmericanImpl">
<property name="name">
<value>Tom</value>
</property>
<property name="age">
<value>15</value>
</property>
</bean>
</beans>
用于测试的Test.java：
package com.spring;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.bean.Person;
public class Test {
public static void main(String[] args) {
ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
Person person=(Person)context.getBean("chinese");
person.Speak();
person=(Person)context.getBean("american");
person.Speak();
}
}
四、测试结果
在Test.Java上右击Run As|Java Application，输出结果如下：
