设置嵌入式servlet容器默认情况下，SpringBoot使用嵌入式servlet容器(Tomcat )
1 .如何自定义servlet相关配置：
server.port=8080 server.context-path=/web #通用servlet容器设置# server.xxx# Tomcat设置server.Tomcat.accept-count=
@ beanpublicwebserverfactorycustomizerconfigurablewebserverfactorywebserverfactorycustomizer () { returnnewebserverfactorycustomizerconfigurablewebserverfactory (} { @ overridepublicvoidcustomize (可配置webserverfactory ) ； } 3.注册servlet、文件和编写器的组件
创建相关组件
publicclassmyservletextendshttpservlet { @ overrideprotectedvoiddoget (httpservletrequestreq，HttpServletResponse resp ) thro } @ overrideprotectedvoiddopost (httpservletrequestreq，HttpServletResponse resp ) throws ServletException， io exception { sup ption } } publicclassmyfilterimplementsfilter { @ overridepublicvoidinit (filterconfigfilterconfig ) throws sster @ overridepublicvoiddofilter (servletrequestservletrequest，ServletResponse servletResponse，过滤器通道过滤器通道) throws } @ overridepublicvoiddestroy (} publicclassmylistenerimplementsservletcontextlistener ) @overridepublicvoidcontextining } @ overridepublicvoidcontextdestroyed (servletcontexteventsce ) { System.out.println (“服务器关闭”)； }} SpringBoot注册：
