SpringBoot 内置 Tomcat 线程数优化配置

import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.apache.catalina.connector.Connector;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class TomcatConfig {
 
    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        tomcat.addAdditionalTomcatConnectors(createConnector());
        return tomcat;
    }
 
    private Connector createConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setPort(8080);
        // 自定义线程池配置
        connector.setProperty("executor.name", "myExecutor");
        connector.setProperty("executor.namePrefix", "myTomcatThreadPool-");
        connector.setProperty("executor.maxThreads", "200"); // 最大线程数
        connector.setProperty("executor.minSpareThreads", "20"); // 最小空闲线程数
        connector.setProperty("executor.maxIdleTime", "60000"); // 线程最大空闲时间（毫秒）
        return connector;
    }
}

这段代码演示了如何在Spring Boot应用中配置Tomcat的额外连接器，并设置它使用的线程池参数。这可以帮助你根据应用的需求优化处理请求的线程数。
