Spring Boot Tomcat配置详解编程语言

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。

@ConfigurationProperties(prefix = "server", ignoreUnknownFields = true) 
public class ServerProperties 
implements EmbeddedServletContainerCustomizer, EnvironmentAware, Ordered { 
...

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。

// Jetty 
org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory 
// Tomcat 
org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory 
// Undertow 
org.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。

<dependency> 
<groupId>org.springframework.boot</groupId> 
<artifactId>spring-boot-starter-web</artifactId> 
<exclusions> 
<!-- Exclude the Tomcat dependency --> 
<exclusion> 
<groupId>org.springframework.boot</groupId> 
<artifactId>spring-boot-starter-tomcat</artifactId> 
</exclusion> 
</exclusions> 
</dependency> 
<!-- Use Jetty instead --> 
<dependency> 
<groupId>org.springframework.boot</groupId> 
<artifactId>spring-boot-starter-jetty</artifactId> 
</dependency>
