Spring Boot 3.2.0 Tomcat虚拟线程初体验 (部分装配解析)

import org.apache.catalina.connector.Connector;
import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
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> tomcatConnectorCustomizer() {
        return (tomcatServletWebServerFactory) -> {
            tomcatServletWebServerFactory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
                @Override
                public void customize(Connector connector) {
                    // 自定义虚拟线程配置
                    connector.setProperty("acceptCount", "100");
                    connector.setProperty("maxConnections", "100");
                    connector.setProperty("maxThreads", "200");
                    connector.setProperty("minSpareThreads", "20");
                }
            });
        };
    }
}

这段代码定义了一个配置类TomcatConfig，其中创建了一个WebServerFactoryCustomizer的Bean实例。这个Bean会在TomcatServletWebServerFactory被创建时调用，并通过addConnectorCustomizers方法添加了一个自定义的TomcatConnectorCustomizer，用于设置Tomcat连接器的属性，比如acceptCount、maxConnections、maxThreads和minSpareThreads。这些属性可以控制Tomcat连接器的行为，进而影响服务器的性能和资源使用。
