Web 单体应用启动过程

Web 单体应用启动过程

一、基本环境

Sevlet 容器 —- Tomcat

Spring IOC 容器—- Bean容器管理

Spring MVC —- 控制器

二、主要启动过程

这里我以自己抓图项目启动为例。

【已经开启了大部分日志，可能不够完整，后续再进行补充完整】

启动过程之前可以先看看启动日志：

想了想还是把日志加上更为直观。

主要启动步骤

容器初始化

1、web应用启动Servlet容器，加载读取web.xml文件。

Starting Servlet Engine:

web工程的启动就是从Servlet容器加载web.xml开始的。

应用上下文监听初始化

2、加载we.xml 之后，会优先初始化加载 Spring容器加载监听器，也叫上下文监听器：ContextLoaderListener，执行contextInitialized()

启动日志关键词：

 Root WebApplicationContext: initialization started

源码：

public class ContextLoaderListener extends ContextLoader implements ServletContextListener {
    /**
     * Initialize the root web application context.
     */
    @Override
    public void contextInitialized(ServletContextEvent event) {
        initWebApplicationContext(event.getServletContext());
    }

}

IOC容器初始化

3、在初始化web上下文的中，使用XmlWebApplicationContext 加载对应配置的applicationContext.xml 配置文件，进入IOC容器管理 bean 的过程。

启动日志关键词：

XmlBeanDefinitionReader loadBeanDefinitions

MVC–请求路径映射注册

4、IOC 容器加载完成之后，进入SpringMVC 启动环节，收集@GetMapping 地址完成资源路径映射的注册

RequestMappingHandlerMapping register

MVC–DispatcherServlet 初始化

5、URL映射注册完成之后，开始初始化DispatcherServlet

启动日志关键词：

DispatcherServlet initServletBean

Session 监听初始化

6、上下文监听启动结束，完成session监听

启动日志关键词：

ContextListener: contextInitialized()
SessionListener: contextInitialized()

Servlet容器里 协议处理器开始监听请求

7、Servlet容器里 的 ProtocolHandler 协议处理器启动，开始监听Sekcet 请求

启动日志关键词：

ProtocolHandler
