code:
3.1 先看下标记的注解:
@configuration 配置类注解
@autoconfigureorder(ordered.highest_precedence) 自动配置顺序,最高优先级[同级的还有dispatcherservletautoconfiguration。扩展下,还有次高级(webmvcautoconfiguration),无级别(httpencodingautoconfiguration等),依赖链(属于无级别)]
@conditionalonclass(servletrequest.class) 条件类, 指定的servletrequest类存在生效
@conditionalonwebapplication(type = type.servlet) 条件类,指定为web应用下生效
@enableconfigurationproperties(serverproperties.class) 启动serverproperties类的属性值注入功能,将server的port, address等属性注入到ioc容器中
@import({ servletwebserverfactoryautoconfiguration.beanpostprocessorsregistrar.class,
servletwebserverfactoryconfiguration.embeddedtomcat.class,
servletwebserverfactoryconfiguration.embeddedjetty.class,
servletwebserverfactoryconfiguration.embeddedundertow.class }) 导入注册servlet服务配置类,用于返回指定的容器:tomcat/jetty/undertow
3.2 该自动配置类被执行顺序如下:
1)init: beanpostprocessorsregistrar.setbeanfactory/.registerbeandefinitions
2)return: servletwebserverfactorycustomizer
