Spring Boot:由于缺少 EmbeddedServletContainerFactory bean 无法启动 EmbeddedWebApplicationContext [英] Spring Boot: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

问题描述

我对 Spring 完全陌生，并开始从这个网站做官方指南:https://spring.io/guides

我想做这个指南:https://spring.io/guides/gs/scheduling-tasks/>

我收到以下异常:

应用入门类是这样的:

@ComponentScan@EnableAutoConfiguration公共类应用{公共静态无效主(字符串 [] args){SpringApplication.run(ScheduledTasks.class, args);}}

如您所见，main 方法包含一个注释行.我已经做了一个教程，即这个:https://spring.io/guides/gs/消费休息/它已经启动并正在运行.但我无法运行 ScheduledTasks 应用程序，如下所示:

@EnableScheduling公共类计划任务{private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");@Scheduled(fixedRate = 5000)公共无效报告当前时间(){System.out.println("现在是时间" + dateFormat.format(new Date()));}}

我使用 Eclipse 并将 Application.java 的 main 作为应用程序运行.有人可以帮我吗?

解决方案

调度指南不是 Web 应用程序，所以您的 pom.xml 中可能有一些来自 REST 指南的发霉的东西?如果您严格按照说明操作，它应该会起作用.您上面发布的代码的另一个潜在问题是您的 @EnableAutoConfiguration 类未在上下文中使用，仅用作主要方法(这可能不是调度指南的问题，但它可能用于一堆其他人).

I am totally new to Spring and started to do the official guides from this site: https://spring.io/guides

I'd like to do this guide: https://spring.io/guides/gs/scheduling-tasks/

I get the following Exception:

The application starter class is this:

@ComponentScan
@EnableAutoConfiguration
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(ScheduledTasks.class, args);
    }
}

As you can see, the main method contains a commented line. I've already done a tutorial, namely this one: https://spring.io/guides/gs/consuming-rest/ It's up and running. But I can't run the ScheduledTasks app, which is the following:

@EnableScheduling
public class ScheduledTasks {

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime() {
        System.out.println("The time is now " + dateFormat.format(new Date()));
    }
}

I use Eclipse and run the Application.java's main as an Application. Could someone please help me?

解决方案

The scheduling guide isn't a web app so you probably have some mouldy stuff in your pom.xml from the REST guide? If you follow the instructions closely it should work. Another potential issue with the code you posted above is that your @EnableAutoConfiguration class is not used in the context, only as a main method (which may not be a problem for the scheduling guide but it probably is for a bunch of others).
