spring-boot-maven-plugin：启动无法识别应用程序已经启动

• 问答

我正在尝试使用 spring-boot-maven-plugin 进行记录的集成测试，但是我总是得到“ Spring应用程序在配置的超时之前未启动”。但是，使用“ fork = false” spring服务器应用程序会说：

18:30:14.442 [http-nio-8080-exec-1] INFO  o.s.web.servlet.DispatcherServlet.initServletBean - Initializing Servlet 'dispatcherServlet'
18:30:14.446 [http-nio-8080-exec-1] INFO  o.s.web.servlet.DispatcherServlet.initServletBean - Completed initialization in 4 ms
18:30:21.918 [http-nio-8080-exec-2] WARN  o.s.w.s.m.s.DefaulthandlerExceptionResolver.logException - Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported]
18:31:05.899 [http-nio-8080-exec-3] WARN  o.s.w.s.m.s.DefaulthandlerExceptionResolver.logException - Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported]

正因为如此，我想这个插件只是没有发现应用程序已经启动。

但是，我使用“ fork = true”（默认），总是出现以下错误：

这些是我的问题：

  • 插件如何尝试找出应用程序是否已启动？
    • 如果“ fork = true”？ JMX / RMI？哪个端口？哪个MBean？
    • 如果'fork = false'？
  • 在出现'fork = true'的情况下如何避免错误？
