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.domain
2.在包下创建bean
bean名称:CountryGeneralSituation.java
bean内容:
public class CountryGeneralSituation {
private String countryName;//国家名称
private String womb;//发源地
private String relic;//遗址
//省略get and set
}
五.创建业务bean
1.在src下创建包
包名:cn.jbit.spring092901.collection
2.在包下创建bean
bean名称:SetFromRef.java
bean内容:
public class SetFromRef {
private Set<CountryGeneralSituation> set;
public Set<CountryGeneralSituation> getSet() {
return set;
}
public void setSet(Set<CountryGeneralSituation> set) {
this.set = set;
}
}
3.在核心配置文件中配置bean
<bean id="setFromRefBean" class="cn.jbit.spring092901.collection.SetFromRef">
<property name="set">
<set>
<ref bean="egyptBean"/>
</set>
</property>
</bean>
<bean id="egyptBean" class="cn.jbit.spring092901.domain.CountryGeneralSituation">
<property name="countryName" value="埃及"></property>
<property name="womb" value="尼罗河流域"></property>
<property name="relic" value="涅伽达遗址"></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.collection
3.在包下 创建测试类
类名:SetFromRefTest.java
类内容:
public class SetFromRefTest {
@Test
public void testCGS(){
ClassPathXmlApplicationContext cxac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
SetFromRef sfr = (SetFromRef) cxac.getBean("setFromRefBean");
Set set = sfr.getSet();
Iterator it = set.iterator();
while(it.hasNext()){
CountryGeneralSituation cgs = (CountryGeneralSituation) it.next();
System.out.println(cgs.getCountryName());
}
}
}
