Spring 4.2新特性-对java8默认方法(default method)定义Bean的支持

public class DemoService {
    public void doSomething(){
        System.out.println("find bean in default method");
    }
}

package com.wisely.spring4_2.defaultMethod;

import org.springframework.context.annotation.Bean;
public interface DemoServiceConfig {

    @Bean 
    default DemoService DemoService(){
        return new DemoService();
    }

}

package com.wisely.spring4_2.defaultMethod;

import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig implements DemoServiceConfig{



}

package com.wisely.spring4_2.defaultMethod;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Main {
    public static void main(String[] args) {
         AnnotationConfigApplicationContext context =
                    new AnnotationConfigApplicationContext("com.wisely.spring4_2.defaultMethod");
         DemoService ds = context.getBean(DemoService.class);
         ds.doSomething();
    }
}
