Spring Boot 管理日志中重复出现 AsyncRequestTimeoutException

Question

我目前正在本地机器上运行 Spring Boot Admin 以进行测试，并且我不断收到以下错误。应用程序本身似乎运行良好，但我的日志中充满了这些错误。我不知道为什么......

Answer 1

我也有类似的错误。在你的 application.yml 中试试这个属性

spring:
  mvc:
    async:
      request-timeout: -1  

Answer 2

或者不用spring boot，添加

    @Override
    public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
        long timeout = 5 * 60 * 1000;// for example 5 minutes
        WebMvcConfigurer.super.configureAsyncSupport(configurer);
        configurer.setDefaultTimeout(timeout);
    }

到实现WebMvcConfigurer的配置类

Answer 3

如果使用ComplatebleFuture<Any>作为@RestController函数的返回类型并使用Tomcat作为后备容器。则需要将catalina连接器定制器注册到spring上下文中，这将调整异步连接超时。因为org.apache.catalina.connector.Connector 有自己的属性protected long asyncTimeout = 30000; 用作异步请求的超时时间。

@Configuration
class TomcatAsyncConfig {
    @Bean
    fun asyncTimeoutCustomize(): TomcatConnectorCustomizer =
        TomcatConnectorCustomizer { connector -> connector.asyncTimeout = 180000 }
}

修改值 spring.mvc.async.request-timeout: -1 或server.tomcat.connection-timeout 不行。

Answer 4

您可以为特定订阅配置超时，而不是在应用程序级别配置超时。

    @GetMapping(value = "/subscription")
    public SseEmitter subscription() {
        SseEmitter emitter = new SseEmitter((long) (60000 * 5));
        return emitter;
    }

所以在上面的摘录中，我给了这个特定的连接 5 分钟。其余连接仍将使用服务器默认超时。
