参数配置容器
server.xx开头的是所有servlet容器通用的配置，server.tomcat.xx开头的是tomcat特有的参数，其它类似。
所有参数绑定配置类：org.springframework.boot.autoconfigure.web.ServerProperties

代码配置容器
除了利用上面的参数来自动配置servlet容器，还可以通过代码的方式。可以直接实现EmbeddedServletContainerCustomizer这个接口，ServerProperties也是实现这个接口的。
1@ConfigurationProperties(prefix = "server", ignoreUnknownFields = true) 2public class ServerProperties 3 implements EmbeddedServletContainerCustomizer, EnvironmentAware, Ordered { 4...
当然如果是Tomcat、Jetty、Undertow也可以使用下面对应的特定的容器工厂类。
1// Jetty 2org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory 3 4// Tomcat 5org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory 6 7// Undertow 8org.springframework.boot.context.embedded.undertow.UndertowEmbeddedServletContainerFactory
替换Tomcat
spring-boot-starter-web brings Tomcat with spring-boot-starter-tomcat, but spring-boot-starter-jetty and spring-boot-starter-undertow can be used instead.
spring-boot-starter-web自动携带了tomcat依赖，但也可以替换成jetty和undertow，下面是一个替换jetty的示例。
1<dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-web</artifactId> 4 <exclusions> 5 <!-- Exclude the Tomcat dependency --> 6 <exclusion> 7 <groupId>org.springframework.boot</groupId> 8 <artifactId>spring-boot-starter-tomcat</artifactId> 9 </exclusion> 10 </exclusions> 11</dependency> 12<!-- Use Jetty instead --> 13<dependency> 14 <groupId>org.springframework.boot</groupId> 15 <artifactId>spring-boot-starter-jetty</artifactId> 16</dependency>
