1、Tomcat配置
Spring Boot預設內嵌的Tomcat為Servlet容器，所以本節只講對Tomcat配置，其實本節的配置對Tomcat、Jetty和Undertow都是通用的。
1.1 配置Tomcat
關於Tomcat的所有屬性都在org.springframework.boot.autoconfigure.web.ServerProperties配置類中做了定義，我們只需在application.properties配置屬性做配置即可。通用的Servlet容器配置都以"server"作為字首，而Tomcat特有配置都以"server.tomcat"作為字首。下面舉一些常用的例子。
- 1
配置servlet容器
server.port = #配置程式埠，預設為8080server.session-timeout=#使用者session過期，以秒為單位
- 1
- 2
- 3
配置Tomcat
server.tomcat-uri-encoding = #配置Tomcat編碼，預設為UTF-8
server.tomcat.compression = #Tomcat是否開啟壓縮，預設為關閉off
1.2 程式碼配置Tomcat
如果你需要通過程式碼的方式配置servlet容器，則可以註冊一個實現EmbeddedServletContainerCustomizer介面的Bean,若想直接配置Tomcat、Jetty、Undertow,則可以直接定義TomcatEmbeddedServletContainerFactor、JettyEmbeddedServletContainerFactor、UndertowEmbeddedServletContainerFactor。

1.2.2 pom.xml的內容如下
