SpringBoot配置tomcat

在Spring Boot中，Tomcat是默认嵌入式Servlet容器。如果需要配置Tomcat，可以在application.properties或application.yml文件中设置相关属性，或者通过编程的方式进行配置。

以下是一些常见的Tomcat配置示例：

1. 修改application.properties:

server.tomcat.max-threads=200
server.tomcat.uri-encoding=UTF-8
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.directory=logs
server.tomcat.accesslog.pattern=%h %t "%r" %s %b %D

2. 修改application.yml:

server:
  tomcat:
    max-threads: 200
    uri-encoding: UTF-8
    accesslog:
      enabled: true
      directory: logs
      pattern: "%h %t \"%r\" %s %b %D"

3. 编程方式配置（在配置类中）:

import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class TomcatConfig {
 
    @Bean
    public WebServerFactoryCustomizer<TomcatServletWebServerFactory> tomcatCustomizer() {
        return (tomcatServletWebServerFactory) -> {
            tomcatServletWebServerFactory.setPort(8080);
            tomcatServletWebServerFactory.setUriEncoding(Charset.forName("UTF-8"));
            tomcatServletWebServerFactory.addContextValves(getAccessLogValve());
        };
    }
 
    private AccessLogValve getAccessLogValve() {
        AccessLogValve logValve = new AccessLogValve();
        logValve.setDirectory("logs");
        logValve.setEnabled(true);
        logValve.setPattern("%h %t \"%r\" %s %b %D");
        logValve.setPrefix("access_log.");
        logValve.setSuffix(".txt");
        return logValve;
    }
}

请注意，编程配置需要你在配置类路径下添加Apache Tomcat相关依赖，并且AccessLogValve是Apache Tomcat特有的类，不是Spring Boot的标准库。
