SpringMVC子父容器源码剖析

一、子父容器启动流程

在这里插入图片描述

二、环境准备

python源码剖析第二版、spring源码搭建
spring-framework-5.1.x 源码编译环境搭建 [ idea:2020.1 ]
在spring源码中创建一个新的module

dockerfile里封装ruby。build.gradle

plugins {id 'java'id 'war'
}group 'com.dabing.springmvc'
version '5.1.13.BUILD-SNAPSHOT'sourceCompatibility = 11repositories {mavenCentral()
}dependencies {compile(project(":spring-webmvc"))compile(project(":spring-tx"))compile(project(":spring-jdbc"))testCompile group: 'junit', name: 'junit', version: '4.12'
}

web.xml （DispatcherServlet配置的请求时进行加载创建）

ControllerDemo

@Controller
@RequestMapping("/demo")
public class ControllerDemo{@RequestMapping("/handle01")public String handle01(String name, Map<String,Object> model) {System.out.println("++++++++handler业务逻辑处理中....");Date date = new Date();model.put("date",date);return "success";}
}
