springboot项目中使用jetty web服务器

Servlet规范支持方面
(1)Jetty的应用更加快速,修改简单,对新的Servlet规范的支持较好。 GAE(谷歌应用引擎已经全面切换为Jetty)
(2)Tomcat目前应用比较广泛,对JavaEE和Servlet的支持更加全面,很多特性会直接集成进来。(中小企业还再在用)

导包 spring-boot-starter-jetty,并排除spring-boot-starter-web里面的spring-boot-starter-tomcat。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

在spring-boot-autoconfigure 这个jar中的org.springframework.boot.autoconfigure.web.servlet.ServletWebServerFactoryAutoConfiguration类中, 通过Import注解加入了Jetty的支持

@Configuration
@AutoConfigureOrder(Ordered.HIGHEST_PRECEDENCE)
@ConditionalOnClass(ServletRequest.class)
@ConditionalOnWebApplication(type = Type.SERVLET)
@EnableConfigurationProperties(ServerProperties.class)
@Import({ ServletWebServerFactoryAutoConfiguration.BeanPostProcessorsRegistrar.class,
        ServletWebServerFactoryConfiguration.EmbeddedTomcat.class,
        ServletWebServerFactoryConfiguration.EmbeddedJetty.class,
        ServletWebServerFactoryConfiguration.EmbeddedUndertow.class })
public class ServletWebServerFactoryAutoConfiguration {

    @Bean
    public ServletWebServerFactoryCustomizer servletWebServerFactoryCustomizer(
            ServerProperties serverProperties) {
        return new ServletWebServerFactoryCustomizer(serverProperties);
    }

    @Bean
    @ConditionalOnClass(name = "org.apache.catalina.startup.Tomcat")
    public TomcatServletWebServerFactoryCustomizer tomcatServletWebServerFactoryCustomizer(
            ServerProperties serverProperties) {
        return new TomcatServletWebServerFactoryCustomizer(serverProperties);
    }

    ...
}

常用配置

server.port=8080
server.servlet.context-path=/

server.jetty.thread-idle-timeout=60000
server.jetty.connection-idle-timeout=30000
server.jetty.max-http-form-post-size=1000
server.jetty.max-threads=200
server.jetty.min-threads=10
server.jetty.acceptors=-1
server.jetty.selectors=-1

server.jetty.accesslog.enabled=true
server.jetty.accesslog.append=true
server.jetty.accesslog.retention-period=20
server.jetty.accesslog.file-date-format=.yyyy-MM-dd
server.jetty.accesslog.filename= D:/logs/access_log.yyyy_MM_dd.log

配置https访问

server.ssl.port=8443
server.ssl.enabled=true
server.ssl.key-store=D:/ssl.keystore
server.ssl.key-store-password=0123789
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=ssl_alias
@Value("${server.ssl.key-store:classpath:ssl.keystore}")
private String path;
@Value("${server.ssl.key-store-password:123456}")
private String password;
@Value("${server.port:8443}")
private int port;
@Value("${server.ssl.port:8443}")
private int sslPort;

@Value("${server.jetty.thread-idle-timeout:60000}")
private int timeout;
@Value("${server.jetty.max-threads:200}")
private int maxThreads;
@Value("${server.jetty.max-threads:10}")
private int minThreads;

@Bean
public ServletWebServerFactory servletContainer() {
    JettyServletWebServerFactory container = new JettyServletWebServerFactory();
    container.addServerCustomizers((Server server) -> {
        //配置线程
        final QueuedThreadPool threadPool = server.getBean(QueuedThreadPool.class);
        //默认最大线程连接数
        threadPool.setMaxThreads(maxThreads);
        //默认最小线程连接数
        threadPool.setMinThreads(minThreads);
        //默认线程最大空闲时间60000ms
        threadPool.setIdleTimeout(timeout);

        // 添加HTTP配置
        ServerConnector connector = new ServerConnector(server);
        connector.setPort(port);

        // 添加HTTPS配置
        SslContextFactory sslContextFactory = new SslContextFactory();
        sslContextFactory.setKeyStorePath(path);
        sslContextFactory.setKeyStorePassword(password);

        HttpConfiguration config = new HttpConfiguration();
        config.setSecureScheme(HttpScheme.HTTPS.asString());
        config.addCustomizer(new SecureRequestCustomizer());

        ServerConnector sslConnector = new ServerConnector(
                server,
                new SslConnectionFactory(sslContextFactory, HttpVersion.HTTP_1_1.asString()),
                new HttpConnectionFactory(config));
        sslConnector.setPort(sslPort);
        server.setConnectors(new Connector[]{connector, sslConnector});
    });
    return container;
}
