引言

Spring Boot 是一个用于简化 Spring 应用开发的框架，它通过自动配置和约定优于配置的原则，使得开发者能够快速搭建和运行 Spring 应用。Spring Boot 的核心启动类 SpringApplication 是整个应用的入口，负责应用的初始化和启动。本文将深入分析 SpringApplication 的源码，详细解析 Spring Boot 的启动流程。

SpringBoot启动流程概述

Spring Boot 的启动流程可以概括为以下几个步骤：

1. 初始化 SpringApplication 实例：通过 SpringApplication 的构造函数初始化应用。
2. 准备环境：加载配置文件、设置环境变量等。
3. 创建应用上下文：根据应用类型（如 Web 应用或非 Web 应用）创建相应的 ApplicationContext。
4. 刷新应用上下文：加载 Bean 定义、初始化 Bean、启动 Web 服务器等。
5. 执行 Runners：执行 ApplicationRunner 和 CommandLineRunner。
6. 启动完成：应用启动完成，进入运行状态。

SpringApplication类结构

SpringApplication 类是 Spring Boot 启动的核心类，它负责整个应用的初始化和启动。SpringApplication 的主要结构如下：
