SpringBoot中修改内嵌tomcat的3种方式

方式一、修改application.properties文件中属性

server.port=8081
server.address=127.0.0.1
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.directory=d\:/springboot/logs

　　绑定IP：上面的配置只能在浏览器输入localhost:8081或者127.0.0.1访问

　　日志路径：D:\springboot\logs\access_log.2019-12-05.log，（2019-12-05是运行时间）

方式二、实现WebServerFactoryCustomizer接口

@Component
public class MyWebServerFactoryCustomizer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {

    @Override
    public void customize(TomcatServletWebServerFactory factory) {
        factory.setPort(8888);//tomcat端口
        factory.setBaseDirectory(new File("d:/temp/tomcat"));//缓存路径
        factory.addContextValves(getLogAccessLogValue());//设置访问日志
        factory.addConnectorCustomizers(new MyTomcatConnectorCustomizer());//tomcat自定义访问连接
    }

    private AccessLogValve getLogAccessLogValue(){
        AccessLogValve log=new AccessLogValve();
        log.setDirectory("d:/temp/logs");//日志路径
        log.setEnabled(true);//启用日志
        log.setPattern("common");//输入日志格式
        log.setPrefix("springboot-access-log");//日志名称
        log.setSuffix(".txt");//日志后缀
        return log;
    }
}

class MyTomcatConnectorCustomizer implements TomcatConnectorCustomizer {

    @Override
    public void customize(Connector connector) {
        Http11NioProtocol protocal=(Http11NioProtocol)connector.getProtocolHandler();
        protocal.setMaxConnections(20000);//最大连接数
        protocal.setMaxThreads(500);//最大线程数
    }
}

方式三、装配AbstractServletWebServerFactory的bean

@SpringBootConfiguration
public class WebServerConfiguration {

    @Bean
    public AbstractServletWebServerFactory createServletWebServerFactory(){
        TomcatServletWebServerFactory factory=new TomcatServletWebServerFactory();
        factory.setPort(10008);//tomcat端口
        factory.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND,"/404.html"));//设置状态码对应的错误页面
        factory.addContextValves(getLogAccessLogValue());//设置日志
        factory.addInitializers(new MyServletContext());//tomcat容器初始化时执行
        return factory;
    }

    private AccessLogValve getLogAccessLogValue(){
        AccessLogValve log=new AccessLogValve();
        log.setDirectory("d:/temp/logs");//日志路径
        log.setEnabled(true);//启用日志
        log.setPattern("common");//输入日志格式
        log.setPrefix("springboot-access-log");//日志名称
        log.setSuffix(".txt");//日志后缀
        return log;
    }
}

class MyServletContext implements ServletContextInitializer{

    @Override
    public void onStartup(ServletContext servletContext)
            throws ServletException {
        System.out.println("------------servletContext start------------");
    }
}
