Spring Boot外部Tomcat不是异步的

Question

Spring Boot外部Tomcat不是异步的

Ali*_*sam 6 java spring tomcat spring-mvc spring-boot

Callable通过在Spring Boot应用程序上运行的ajax 调用方法时,嵌入式tomcat异步处理请求并完全正常:

但是,当我在外部tomcat服务器上部署应用程序时,一个调用挂起服务器,而下一个调用仅在第一次调用完成后处理.

在上面的日志中,来自Zanzoun和的呼叫同时AJ被发送,但是AJ处理直到Zanzoun结束才开始.

下面我列出我的配置:

@Configuration
@EnableAsync
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("main");
        registry.addViewController("/login").setViewName("login");
        registry.addViewController("/admin").setViewName("admin");
    }

    @Override
    public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
        configurer.setTaskExecutor(asyncTaskExecutor());
    }

    @Bean
    public AsyncTaskExecutor asyncTaskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(200);
        executor.setQueueCapacity(500);
        executor.setThreadNamePrefix("SpringAsyncThread-");
        executor.initialize();
        return executor;
    }
}

@SpringBootApplication
@EnableScheduling
@EnableAsync
public class App extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }
}

我已经使用外部Tomcat在我的Linux机器上进行本地测试8.0.21,它运行良好.但是,我在Windows中安装了相同版本的Tomcat(它实际上是一个AWS实例),问题仍然存在,所以这是一个操作系统/版本问题？

您是否尝试过检查实际池大小，例如通过 JMX： https: //wiki.apache.org/tomcat/FAQ/Monitoring#Thread_Usage？

另外，您可以尝试安装 APR Native 库来验证问题不在于传入流量的自动选择协议：https ://tomcat.apache.org/tomcat-8.0-doc/apr.html

Windows EC2 实例的配置也可能会影响观察到的行为，您能否将其也添加到问题中？
