名称空间/src/com/b510/app/test/SpringTest.java

com.b510.app.test; org.springframework.context.ApplicationContext; org.springframework.context.support.ClasspathXmlApplicationContext; com.b510.service.AnimalService; SpringTest { main(String[] args) { ApplicationContext act = ClasspathXmlApplicationContext("beans.xml"); 获取id为animaleServiceOfDog的Bean AnimalService animalServiceOfDog = (AnimalService) act .getBean("animaleServiceOfDog"); animalServiceOfDog.getInfo(); 获取id为animaleServiceOfCat的Bean AnimalService animalServiceOfCat = (AnimalService) act .getBean("animaleServiceOfCat"); animalServiceOfCat.getInfo(); } }

名称空间/src/com/b510/service/AnimalService.java

com.b510.service; AnimalService { 获取相关信息 getInfo(); }

名称空间/src/com/b510/service/MeatService.java

com.b510.service; MeatService { 方法whatMeat 一个字符串 String whatMeat(); }

名称空间/src/com/b510/service/impl/CatServiceBean.java

com.b510.service.impl; com.b510.service.AnimalService; com.b510.service.MeatService; CatServiceBean AnimalService { age; MeatService meatService; getAge() { age; } setAge( age) { .age = age; } @Override getInfo() { System.out.println("我是猫，我的年龄是:"+age+",我很喜欢吃"+meatService.whatMeat()); } MeatService getMeatService() { meatService; } setMeatService(MeatService meatService) { .meatService = meatService; } }

名称空间/src/com/b510/service/impl/DogServiceBean.java

com.b510.service.impl; com.b510.service.AnimalService; com.b510.service.MeatService; DogServiceBean AnimalService { age; MeatService meatService; MeatService getMeatService() { meatService; } setMeatService(MeatService meatService) { .meatService = meatService; } getAge() { age; } setAge( age) { .age = age; } @Override getInfo() { System.out.println("我是狗，我的年龄是:" + age + ",我很喜欢吃" + meatService.whatMeat()); } }

名称空间/src/com/b510/service/impl/FishServiceBean.java

com.b510.service.impl; com.b510.service.MeatService; FishServiceBean MeatService { @Override String whatMeat() { "鱼肉"; } }

名称空间/src/com/b510/service/impl/PorkServiceBean.java

com.b510.service.impl; com.b510.service.MeatService; PorkServiceBean MeatService { @Override String whatMeat() { "猪肉"; } }

名称空间/src/beans.xml

xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http:spring-beans-3.0.xsd"> ="com.b510.service.impl.FishServiceBean"> ="com.b510.service.impl.PorkServiceBean"> ="com.b510.service.impl.DogServiceBean" p:age="12" p:meatService-ref="meatServiceOfPork" /> ="com.b510.service.impl.CatServiceBean" p:age="3" p:meatService-ref="meatServiceOfFish" />

名称空间没有标准的XML格式灵活，如果某个Bean的属性名称是以"-ref"结尾的，那么采用p名称空间定义是就会出现错误，采用标准的XML格式是

错误滴！！！
