IntelliJ IDEA 2017版 Spring5 的RunnableFactoryBean配置

1、新建RunnableFactoryBean

 package com.spring4.pojo;

 import org.springframework.beans.factory.FactoryBean;

 /**
  * Created by liuya
  *
  * @author User: liuya
  *         Date: 2018/5/3
  *         Time:  23:31
  *         projectName:spring4
  */
 public class RunnableFactoryBean implements FactoryBean<Runnable> {

     /**
      * 获取FactoryBean获取的实例对象
      *
      * @return Runnable
      * @throws Exception
      */
     @Override
     public Runnable getObject() throws Exception {
         return () -> {
         };
     }

     /**
      * 创建什么类型的对象
      *
      * @return Class<?>
      */
     @Override
     public Class<?> getObjectType() {
         return Runnable.class;
     }

     /**
      * 是不是单例的
      *
      * @return
      */
     @Override
     public boolean isSingleton() {
         return true;
     }
 }

2、加载到Myconfig中

 package com.spring4.conf;

 import com.spring4.pojo.RunnableFactoryBean;
 import com.spring4.pojo.User;
 import org.springframework.context.annotation.Bean;
 import org.springframework.context.annotation.Configuration;
 import org.springframework.context.annotation.Scope;

 /**
  * Created by liuya
  *
  * @author : liuya
  *         Date: 2018/5/2
  *         Time:  23:50
  *         projectName:spring4
  *         配置类
  */

 @Configuration
 public class SpringConf {

     /**
      * 配置bean 写一个方法,返回bean
      * <p>
      * 指定名字,默认是方法名字
      */
     @Bean(name = "getUser")
     /**
      * 修改为非单例模式,创建的对象就是不一样的了
      *
      */
     @Scope(value = "prototype")
     public User getUser() {
         User user = new User();
         user.setAge(29);
         user.setUserName("王圆圆");
         user.setPassWord("1110000");

         return user;
     }

     @Bean
     public RunnableFactoryBean createRunnableFactoryBean() {
         RunnableFactoryBean runnableFactoryBean = new RunnableFactoryBean();

         return runnableFactoryBean;

     }

 }

3、方法加入Application测试

 package com.study.spring;

 import com.spring4.conf.SpringConf;
 import com.spring4.pojo.RunnableFactoryBean;
 import com.spring4.pojo.User;
 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;
 import org.springframework.context.annotation.AnnotationConfigApplicationContext;

 import java.io.IOException;
 import java.util.List;

 /**
  * @author liuyang
  */
 @SpringBootApplication
 public class Spring4Application {

     public static void main(String[] args) {
         // 通过Java配置来实例化Spring容器
         AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SpringConf.class);

         // 在Spring容器中获取Bean对象
         User user = context.getBean(User.class);

         //根据名字获取(默认是根据方法名字获取)
         Object user2 = context.getBean("getUser");

         System.out.println(user.getUserName() + ", " + user.getAge() + ", " + user.getPassWord());
         System.out.println(user2.toString() + ", ");
         String list = user2.toString();
         String[] ont = list.split(",");
         for (int i = 0; i < ont.length; i++) {
             System.out.println(ont[i]);
         }

         RunnableFactoryBean runnableFactoryBean = context.getBean(RunnableFactoryBean.class);

         try {
             System.out.println("createRunnableFactoryBean  :"+runnableFactoryBean);
         } catch (Exception e) {
             e.printStackTrace();
         }

         // 销毁该容器
         context.destroy();
     }
 }
