Spring Boot 支持的内嵌容器有 Tomcat(默认) 、Jetty 、Undertow 和 Reactor Netty (v2.0+), 借助可插拔(SPI)机制的实现,开发者可以轻松进行容器间的切换。

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<!-- 排除默认的Tomcat依赖 -->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- 引入Jetty 或 Undertow 或 Reactor Netty -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
<!-- <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-undertow</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-reactor-netty</artifactId>
</dependency> -->
</dependencies>

Spring Boot 配置有很多,具体可以参考这里。下面列出一些常见的、与容器相关的配置:

  • 地址:
server.port=8080 # Server HTTP port.
server.address= # Network address to which the server should bind.
  • 压缩:
server.compression.enabled=false # Whether response compression is enabled.
server.compression.excluded-user-agents= # Comma-separated list of user agents for which responses should not be compressed.
server.compression.mime-types=text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/json,application/xml # Comma-separated list of MIME types that should be compressed.
server.compression.min-response-size=2KB # Minimum "Content-Length" value that is required for compression to be performed.
  • 错误:
server.error.include-exception=false # Include the "exception" attribute.
server.error.include-stacktrace=never # When to include a "stacktrace" attribute.
server.error.path=/error # Path of the error controller.
server.error.whitelabel.enabled=true # Whether to enable the default error page displayed in browsers in case of a server error.
  • 其他:
server.connection-timeout= # Time that connectors wait for another HTTP request before closing the connection. When not set, the connector's container-specific default is used. Use a value of -1 to indicate no (that is, an infinite) timeout.
server.http2.enabled=false # Whether to enable HTTP/2 support, if the current environment supports it.
server.max-http-header-size=8KB # Maximum size of the HTTP message header.

我们还可以借助编程的方式来修改这些配置项,即通过实现 WebServerFactoryCustomizer<T> 接口方法:

WebServerFactoryCustomizer

  • 压缩配置
@SpringBootApplication
public class SpringBootConfigurationApplication implements WebServerFactoryCustomizer<JettyServletWebServerFactory> {

public static void main(String[] args) {
SpringApplication.run(SpringBootConfigurationApplication.class, args);
}

@Override
public void customize(JettyServletWebServerFactory factory) {
Compression compression = new Compression();
compression.setEnabled(true);
compression.setMinResponseSize(DataSize.ofBytes(512));
factory.setCompression(compression);
}

}
