SpringBoot3.4.5 开启虚拟线程（JDK21）

配置如下

application.yaml

spring: threads:virtual:enabled: true # 启用虚拟线程

找一个配置类用于Bean配置

  @Bean@Primarypublic AsyncTaskExecutor asyncTaskExecutor(){// 用于@Async注解return new TaskExecutorAdapter(Executors.newThreadPerTaskExecutor(Thread.ofVirtual().name("virtual-async#",1).factory()));}@Beanpublic WebServerFactoryCustomizer<TomcatServletWebServerFactory> virtualThreadTomcatCustomizer() {//tomcat容器使用虚拟线程return factory -> factory.addConnectorCustomizers(connector -> {connector.getProtocolHandler().setExecutor(Executors.newThreadPerTaskExecutor(// 定义线程前缀和初始化编号Thread.ofVirtual().name("virtual-thread#", 1).factory()));});}
