java - 主类没有完成启动应用程序 spring Java
问题描述
我正在尝试在 Eclipse 中启动我的 Spring 应用程序，但是当我选择 RightBtn --> Run as --> Spring boot App 时，执行启动过程似乎并没有完成。事实上，eclipse 正在部署我的应用程序，我可以通过 REST ( http://localhost.. ) 与它进行交互。但是当我看到控制台时，我看到它在完成读取 main 方法时停止在控制台中打印消息。（我把日志放在结果部分）
我试图弄清楚为什么会发生这种情况，因为通常当我启动一个 Spring 应用程序时，我会得到类似于我在输出部分中发布的内容：
我认为它与 bean 声明无关，因为我在日志中看到了以下内容：
'configurationPropertiesRebinderAutoConfiguration' of type [org.springframework.cloud.autoconfigure.ConfigurationPropertiesRebinderAutoConfiguration$$EnhancerBySpringCGLIB$$7738e7d1] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
正如我在下面的链接中看到的（类不符合所有 BeanPostProcessors 处理的资格），我不应该担心它。所以不知道问题出在哪里。
我已经尝试了很多东西，评论了我包含的一些标签，但仍然是同样的问题。我想我混合了太多标签，所以在某些时候我的应用程序无法继续并且没有显示任何错误。
我认为我错了，所以我决定从 git ( https://github.com/igorkosandyak/spring-boot-kafka ) 下载代码，以观察真正的输出应该是什么样子。

我注意到这是在我从远程配置服务器读取 applitcation.yml 文件的配置之后开始的。所以我查看了我的 bootstrap.properties 文件发生了什么。
spring.application.name=kafkaclient
ribbon.eureka.enabled=false
this is the default
spring.cloud.config.profile=dev
spring.cloud.config.uri=http://config-service-remote.domain.corp
如果我评论声明配置服务器（spring.cloud.config.uri）和配置文件（spring.cloud.config.profile）的行，应用程序将继续部署。但问题是我需要从该配置服务器中读取，所以有什么想法为什么会发生这种情况？
----更新2 -----
正如 deadpool 推荐的那样，我开始了一个没有 ControllerFPC 类的新项目，并创建了一个只启动应用程序的新主类。我在这个来源（https://www.confluent.io/blog/apache-kafka-spring-boot-application）中启发了自己，但仍然遇到同样的问题。当我声明引导变量 (spring.cloud.config.uri= http://config-service-remote.domain.corp ) 我的应用程序没有完成部署。

信不信由你，这个问题与配置服务器或我之前所说的无关。我的问题是我的applications.yml，这个错误非常愚蠢但也非常令人困惑，因为它没有任何意义。问题是，如果你使用制表符来保持结构，你最终会导致文件崩溃，所以什么都不会起作用，当然你不会理解，最后你会感到沮丧。最好使用空格键制表，这听起来很傻，但对我有用。好吧，我向您展示了一个很好的例子来说明问题所在
