code:
3.1 先看下标記的注解:
@configuration 配置類注解
@autoconfigureorder(ordered.highest_precedence) 自動配置順序,最高優先級[同級的還有dispatcherservletautoconfiguration。擴充下,還有次進階(webmvcautoconfiguration),無級别(httpencodingautoconfiguration等),依賴鍊(屬于無級别)]
@conditionalonclass(servletrequest.class) 條件類, 指定的servletrequest類存在生效
@conditionalonwebapplication(type = type.servlet) 條件類,指定為web應用下生效
@enableconfigurationproperties(serverproperties.class) 啟動serverproperties類的屬性值注入功能,将server的port, address等屬性注入到ioc容器中
@import({ servletwebserverfactoryautoconfiguration.beanpostprocessorsregistrar.class,
servletwebserverfactoryconfiguration.embeddedtomcat.class,
servletwebserverfactoryconfiguration.embeddedjetty.class,
servletwebserverfactoryconfiguration.embeddedundertow.class }) 導入注冊servlet服務配置類,用于傳回指定的容器:tomcat/jetty/undertow
3.2 該自動配置類被執行順序如下:
1)init: beanpostprocessorsregistrar.setbeanfactory/.registerbeandefinitions
2)return: servletwebserverfactorycustomizer
