Spring Boot Tomcat配置

參數配置容器

server.xx開頭的是全部servlet容器通用的配置，server.tomcat.xx開頭的是tomcat特有的參數，其它相似。

代碼配置容器

除了利用上面的參數來自動配置servlet容器，還能夠經過代碼的方式。能夠直接實現EmbeddedServletContainerCustomizer這個接口，ServerProperties也是實現這個接口的。

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

固然若是是Tomcat、Jetty、Undertow也能夠使用下面對應的特定的容器工廠類。

// Jetty
org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory

// Tomcat
org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory

// Undertow
org.springframework.boot.context.embedded.undertow.UndertowEmbeddedServletContainerFactory

替換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自動攜帶了tomcat依賴，但也能夠替換成jetty和undertow，下面是一個替換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>
