# 实验二 利用Spring boot的自动装配特性实现动态注册组件

## 一、自动装配

1. 创建一个自定义的CommandLineRunner接口的实现类。

2. 创建一个自定义的自动配置类，给自动配置类添加有效条件

3. 自定义的一个Bean，绑定属性值，并生成spring配置类的元数据文件

4. 创建spring.factories文件

5. 在application.properties属性文件中添加一个自定义的属性

6. 运行

## 二、自定义事件发布器

1. 自定义事件发布器，配置线程池使其支持多线程异步处理事件

   ![image-20200408015156155](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015156155.png)

2. 自定义事件监听器

3. 自定义事件实体类

   ![image-20200408015310037](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015310037.png)

4. 编写单元测试

   ![image-20200408015420153](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015420153.png)

5. 运行

   ![image-20200408015444446](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015444446.png)

## 三、自定义线程池

1. 查看TaskExecutionAutoConfiguration源码，发现如果没有Executor类型的bean就会自动为我们创建默认的线程池

   ![image-20200408015655691](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015655691.png)

2. 自定义线程池

![image-20200408015951196](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408015951196.png)

3. 断点调试验证是否生效

   ![image-20200408020136650](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408020136650.png)
   ![image-20200408020202600](https://gitee.com/kevinsoft/spring_boot_experiment_2/raw/master/images/image-20200408020202600.png)
   taskExecutor对象引用为同一个，自定义线程池生效。
