AppConfig.java:

package com.nice.config; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; /** * @author ningh */ @Configuration @ComponentScan(basePackages = "com.nice.*", lazyInit = true) public class AppConfig { }

Animal.java:

package com.nice.pojo.definition; /** * 动物接口 * @author ningh */ public interface Animal { public void use(); }

Person.java:

package com.nice.pojo.definition; /** * 人类接口 * @author ningh */ public interface Person { /** * 使用动物服务 */ public void service(); /** * 设置动物 * @param animalal 动物 */ public void setAnimal(Animal animalal); }

BusinessPerson.java:

package com.nice.pojo; import com.nice.pojo.definition.Animal; import com.nice.pojo.definition.Person; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Component; /** * 人物实现类 * @author ningh */ @Component public class BussinessPerson implements Person { @Autowired(required = false) @Qualifier("dog") private Animal animal; @Override public void service() { this.animal.use(); } @Autowired @Qualifier("dog") @Override public void setAnimal(Animal animal) { System.out.println("延迟依赖注入"); this.animal = animal; } }

Cat.java:

package com.nice.pojo; import com.nice.pojo.definition.Animal; import org.springframework.context.annotation.Primary; import org.springframework.stereotype.Component; /** * 猫的实现类 * @author ningh */ @Component @Primary public class Cat implements Animal { @Override public void use() { System.out.println("猫["+Cat.class.getSimpleName()+"]是抓老鼠"); } }

Dog.java:

package com.nice.pojo; import com.nice.pojo.definition.Animal; import org.springframework.stereotype.Component; /** * 狗的实现类 * @author ningh */ @Component public class Dog implements Animal { @Override public void use() { System.out.println("狗[" + Dog.class.getSimpleName() + "]是看门用的."); } }

 

测试方法为:

@Test public void test1(){ ApplicationContext applicationContext = new AnnotationConfigApplicationContext(AppConfig.class); BussinessPerson bussinessPerson = (BussinessPerson) applicationContext.getBean("bussinessPerson"); }

加入生命周期接口和自定义:

package com.nice.pojo; import com.nice.pojo.definition.Animal; import com.nice.pojo.definition.Person; import org.springframework.beans.BeansException; import org.springframework.beans.factory.*; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; import javax.annotation.PostConstruct; import javax.annotation.PreDestroy; /** * 人物实现类 * @author ningh */ @Component public class BussinessPerson implements Person, BeanNameAware, BeanFactoryAware, ApplicationContextAware, InitializingBean, DisposableBean { @Autowired(required = false) @Qualifier("dog") private Animal animal; @Override public void service() { this.animal.use(); } @Autowired @Qualifier("dog") @Override public void setAnimal(Animal animal) { System.out.println("延迟依赖注入"); this.animal = animal; } @Override public void setBeanFactory(BeanFactory beanFactory) throws BeansException { System.out.println("["+this.getClass().getSimpleName()+"] 调用BeanFactoryAware的setBeanFactory"); } @Override public void setBeanName(String s) { System.out.println("["+this.getClass().getSimpleName()+"]调用BeanNameAware的setBeanName"); } @Override public void destroy() throws Exception { System.out.println("["+this.getClass().getSimpleName()+"] DisposableBean方法"); } @PreDestroy public void destory1(){ System.out.println("["+this.getClass().getSimpleName()+"] 注解PreDestroy定义的自定义的销毁方法"); } @PostConstruct public void init(){ System.out.println("["+this.getClass().getSimpleName()+"] 注解@PostConstruct定义的自定义初始化方法"); } @Override public void afterPropertiesSet() throws Exception { System.out.println("["+this.getClass().getSimpleName()+"] 调用InitializingBean的afterPropertiesSet方法"); } @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { System.out.println("["+this.getClass().getSimpleName()+"] 调用ApplicationContextAware的setApplicationContext"); } }

后置bean初始化器:

测试方法为:

@Test public void test2(){ AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class); context.close(); }
