一.创建项目
项目名称:spring092901
二.添加jar包
commons-logging.jar
junit-4.4.jar
log4j.jar
spring-beans-3.2.0.RELEASE.jar
spring-context-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-expression-3.2.0.RELEASE.jar
三.添加配置文件
1.在项目中创建conf目录
/conf
2.在conf目录下添加配置文件
配置文件名称:applicationContext.xml
配置文件内容:
<?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:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">
</beans>
四.创建实体bean
1.在src下创建包
包名:cn.jbit.spring092901.extend
2.在包下创建bean
bean名称:Emperor.java
bean内容:
public class Emperor {
private String nationality;//国籍
private String name;//名称
//省略get and set
}
3.在核心配置文件中配置bean
<!--
子bean
-->
<bean id="yaobean" parent="emperorbean">
<property name="name" value="尧"></property>
</bean>
<!--
父bean
-->
<bean id="emperorbean" class="cn.jbit.spring092901.extend.Emperor">
<property name="nationality" value="中华人民共和国"></property>
</bean>
六.测试
1.在项目中创建test目录
/test
2.在test目录下创建包
cn.jbit.spring092901.extend
3.在包下 创建测试类
类名:ExtendTest.java
类内容:
public class ExtendTest {
@Test
public void testExtend(){
ClassPathXmlApplicationContext cpac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
Emperor emperor = (Emperor) cpac.getBean("yaobean");
System.out.println(emperor.getName()+emperor.getNationality());
}
项目名称:spring092901

spring-context-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-expression-3.2.0.RELEASE.jar
