java–Spring Boot外部Tomcat不是异步的,第1张

概述通过在Spring Boot应用程序上运行的ajax调用Callable方法时,嵌入式tomcat异步处理请求并完全正常：2017-07-02 09:12:24.283 INFO 3582 --- [nio-8090-exec-3] c.r.web.controllers.MainController : Ali was stored in r

通过在Spring Boot应用程序上运行的AJAX调用Callable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AJ的电话同时被发送,但是在Zanzoun结束之前AJ处理没有开始.

下面我列出我的配置：

@Configuration@EnableAsyncpublic 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@EnableAsyncpublic 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);    }}

更新1

我应用了@divine评论中提供的答案,但问题没有解决：

更新2

我已经使用外部Tomcat 8.0.21在我的linux机器上进行了本地测试,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 *** 作系统/版本问题？

更新3

这是所要求的pom文件：

最佳答案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？
此外,您是否可以尝试安装APR Native库来验证问题不是自动选择的传入流量协议：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,您是否也可以将其添加到问题中？
          总结
