1、Tomcat配置

Spring Boot默认内嵌的Tomcat为Servlet容器，所以本节只讲对Tomcat配置，其实本节的配置对Tomcat、Jetty和Undertow都是通用的。

1.1 配置Tomcat

关于Tomcat的所有属性都在org.springframework.boot.autoconfigure.web.ServerProperties配置类中做了定义，我们只需在application.properties配置属性做配置即可。通用的Servlet容器配置都以"server"作为前缀，而Tomcat特有配置都以"server.tomcat"作为前缀。下面举一些常用的例子。

配置servlet容器

server.port = #配置程序端口，默认为8080
server.session-timeout=#用户session过期，以秒为单位
server.context-path= #配置访问路径，默认为/

配置Tomcat

server.tomcat-uri-encoding = #配置Tomcat编码，默认为UTF-8
server.tomcat.compression = #Tomcat是否开启压缩，默认为关闭off

1.2 代码配置Tomcat

如果你需要通过代码的方式配置servlet容器，则可以注册一个实现EmbeddedServletContainerCustomizer接口的Bean,若想直接配置Tomcat、Jetty、Undertow,则可以直接定义TomcatEmbeddedServletContainerFactor、JettyEmbeddedServletContainerFactor、UndertowEmbeddedServletContainerFactor。

1.2.1 编写案例，项目目录如下

这里写图片描述

1.2.2 pom.xml的内容如下
