创建SpringApplication阶段

  • 保存当前主启动类信息class com.atguigu.boot.Boot09HelloTestApplication
  • 使用工具类ClassUtils判定当前应用的类型。一般是Servlet类型
  • bootstrappers：初始启动引导器（List）：去spring.factories文件中找 org.springframework.boot.Bootstrapper
  • 找 ApplicationContextInitializer；去spring.factories找 ApplicationContextInitializer
    • List> initializers

  • 找 ApplicationListener ；应用监听器。去spring.factories找 ApplicationListener

    • List> listeners

      运行 SpringApplication阶段

  • StopWatch记录应用的启动时间

  • 创建引导上下文（Context环境）createBootstrapContext()
    • 获取到所有之前的 bootstrappers 挨个执行 intitialize() 来完成对引导启动器上下文环境设置
  • 让当前应用进入headless模式。java.awt.headless
  • 获取所有 RunListener（运行监听器）【为了方便所有Listener进行事件感知】
    • getSpringFactoriesInstances 去spring.factories找 SpringApplicationRunListener.
  • 遍历 SpringApplicationRunListener 调用 starting 方法；
    • 相当于通知所有感兴趣系统正在启动过程的人，项目正在 starting。
  • 保存命令行参数；ApplicationArguments
  • 准备环境 prepareEnvironment（）;
    • 返回或者创建基础环境信息对象。StandardServletEnvironment
    • 读取所有的配置源的配置属性值。得到所有的PropertySources，@PropertySources即加载外部所有的配置文件xxx.properties
    • 配置激活环境Profile信息,configureProfiles(environment, args);
    • 监听器调用 listener.environmentPrepared()；通知所有的监听器当前环境准备完成
  • 创建IOC容器（createApplicationContext（））
    • 根据项目类型（Servlet）创建容器，
    • 当前会创建 AnnotationConfigServletWebServerApplicationContext
  • 准备ApplicationContext IOC容器的基本信息 prepareContext()
    • 保存环境信息
    • IOC容器的后置处理流程。
    • 应用初始化器；applyInitializers；
  • 遍历所有的 ApplicationContextInitializer 。调用 initialize.。来对ioc容器进行初始化扩展功能
  • 遍历所有的 listener 调用 contextPrepared。EventPublishRunListenr；通知所有的监听器contextPrepared
    • 所有的监听器 调用 contextLoaded。通知所有的监听器 contextLoaded；
  • 刷新IOC容器。refreshContext【核心源码】
    • 创建容器中的所有组件（Spring注解）
  • 容器刷新完成后工作？afterRefresh
  • 所有监听 器 调用 listeners.started(context); 通知所有的监听器 started
  • 调用所有runners；callRunners()
    • 获取容器中的ApplicationRunner
    • 获取容器中的 CommandLineRunner
    • 合并所有runner并且按照@Order进行排序
    • 遍历所有的runner。先ApplicationRunner 后CommandLineRunner调用 run 方法
  • 如果以上有异常，
    • 调用Listener 的 failed
  • 调用所有监听器的 running 方法 listeners.running(context); 通知所有的监听器 running

  • running如果有问题。继续通知 failed 。调用所有 Listener 的 failed；通知所有的监听器 failed

    测试监控springboot启动的各个环节

    以下黄颜色的5个组件就是我们要监控的组件：

  • ApplicationContextInitializer

  • ApplicationListener
  • SpringApplicationRunListener
  • ApplicationRunner
  • CommandLineRunner

image.png
其中需要注意MyApplicationContextInitializer、MyApplicationListener、MySpringApplicationRunListener这三个不需要加上加上@Component，但需要配到自己的**spring.factories**里面：配置成我们的对象

  1. com.atguigu.boot.listener.MyApplicationContextInitializer
  2. com.atguigu.boot.listener.MyApplicationListener
  3. com.atguigu.boot.listener.MySpringApplicationRunListener

image.png
剩下两个MyApplicationRunner和MyCommandLineRunner不用配置到**spring.factories**
因为获取容器中的ApplicationRunner ，获取容器中的 CommandLineRunner
加上@Component，加上@Component即可

调用所有runners；callRunners() 获取容器中的ApplicationRunner 获取容器中的 CommandLineRunner 合并所有runner并且按照@Order进行排序 遍历所有的runner。先ApplicationRunner 后CommandLineRunner调用 run 方法

MyApplicationContextInitializer

  1. package com.atguigu.boot.listener;
  3. import org.springframework.context.ApplicationContextInitializer;
  4. import org.springframework.context.ConfigurableApplicationContext;
  6. public class MyApplicationContextInitializer implements ApplicationContextInitializer {
  7.     @Override
  8.     public void initialize(ConfigurableApplicationContext applicationContext) {
  9.         System.out.println("MyApplicationContextInitializer ....initialize.... ");
  10.     }
  11. }

MyApplicationListener

  1. package com.atguigu.boot.listener;
  3. import org.springframework.context.ApplicationEvent;
  4. import org.springframework.context.ApplicationListener;
  6. public class MyApplicationListener implements ApplicationListener {
  7.     @Override
  8.     public void onApplicationEvent(ApplicationEvent event) {
  9.         System.out.println("MyApplicationListener.....onApplicationEvent...");
  10.     }
  11. }

MySpringApplicationRunListener

这些方法代表我们监听的Spring的一些操作状态

  • 既能监听到做一些打印信息
  • 也可以拿到具体状态阶段创建或者更新的对象（方法参数），这是个回调机制 ```java package com.atguigu.boot.listener;

import org.springframework.boot.ConfigurableBootstrapContext; import org.springframework.boot.SpringApplication; import org.springframework.boot.SpringApplicationRunListener; import org.springframework.context.ConfigurableApplicationContext; import org.springframework.core.env.ConfigurableEnvironment;

public class MySpringApplicationRunListener implements SpringApplicationRunListener {

  1. private SpringApplication application;
  2. public MySpringApplicationRunListener(SpringApplication application, String[] args){
  3.     this.application = application;
  4. }
  6. @Override
  7. public void starting(ConfigurableBootstrapContext bootstrapContext) {
  8.     System.out.println("MySpringApplicationRunListener....starting....");
  10. }
  13. @Override
  14. public void environmentPrepared(ConfigurableBootstrapContext bootstrapContext, ConfigurableEnvironment environment) {
  15.     System.out.println("MySpringApplicationRunListener....environmentPrepared....");
  16. }
  19. @Override
  20. public void contextPrepared(ConfigurableApplicationContext context) {
  21.     System.out.println("MySpringApplicationRunListener....contextPrepared....");
  23. }
  25. @Override
  26. public void contextLoaded(ConfigurableApplicationContext context) {
  27.     System.out.println("MySpringApplicationRunListener....contextLoaded....");
  28. }
  30. @Override
  31. public void started(ConfigurableApplicationContext context) {
  32.     System.out.println("MySpringApplicationRunListener....started....");
  33. }
  35. @Override
  36. public void running(ConfigurableApplicationContext context) {
  37.     System.out.println("MySpringApplicationRunListener....running....");
  38. }
  40. @Override
  41. public void failed(ConfigurableApplicationContext context, Throwable exception) {
  42.     System.out.println("MySpringApplicationRunListener....failed....");
  43. }

}

我们看看官方的spring.factories的SpringApplicationRunListener是怎么写的
image.png
搜一下EventPublishingRunListener发现EventPublishingRunListener写了有参构造器，所以我们模仿EventPublishingRunListener给我们的MySpringApplicationRunListener也添加有参构造器
image.png

  1.     //这也指示我们SpringApplicationRunListener会在初始化的时候拿到SpringApplication对象实例
  2.     private SpringApplication application;
  3.     public MySpringApplicationRunListener(SpringApplication application, String[] args){
  4.         this.application = application;
  5.     }

MyApplicationRunner

  1. package com.atguigu.boot.listener;
  3. import org.springframework.boot.ApplicationArguments;
  4. import org.springframework.boot.ApplicationRunner;
  5. import org.springframework.core.annotation.Order;
  6. import org.springframework.stereotype.Component;
  9. @Order(1)
  10. @Component
  11. public class MyApplicationRunner implements ApplicationRunner {
  12.     @Override
  13.     public void run(ApplicationArguments args) throws Exception {
  14.         System.out.println("MyApplicationRunner...run...");
  15.     }
  16. }

MyCommandLineRunner

  1. package com.atguigu.boot.listener;
  3. import org.springframework.boot.CommandLineRunner;
  4. import org.springframework.core.annotation.Order;
  5. import org.springframework.stereotype.Component;
  7. /**
  8.  * 应用启动做一个一次性事情
  9.  */
  10. @Order(2)
  11. @Component
  12. public class MyCommandLineRunner implements CommandLineRunner {
  13.     @Override
  14.     public void run(String... args) throws Exception {
  15.         System.out.println("MyCommandLineRunner....run....");
  16.     }
  17. }
