Maven JVM服务器端口选项

jvm选项

-Dserver.port=-1

是什么意思？我知道将其设置为0意味着随机端口。有一篇很好的文章。

它的意思是“创建一个WebApplicationContext，但不要启动服务器”。

让我们看一下从同一个使用不同选项运行的测试spring应用程序中截取的两个屏幕截图

在这里，当应用程序使用

server.port=-1

option运行时，服务器启动通知丢失。

谢谢Dave！如果我们使用的是嵌入式服务器，比如任何spring boot应用程序，你能评论一下这个选项会产生什么影响吗？这就是我的意思（嵌入式服务器没有启动）。是的，我理解。我关心的是，这个选项对于嵌入式服务器来说是如何相关的。 . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.0.2.RELEASE) 2014-05-29 09:59:31.815 INFO 2756 --- [ main] s.t.spring.security.config.Application : Starting Application on KOLTM28902K0NX with PID 2756 (C:\Users\607130889\Share\s pring-security-test-0.0.1-SNAPSHOT.jar started by 607130889 in C:\Users\607130889\Share) 2014-05-29 09:59:31.908 INFO 2756 --- [ main] ationConfigEmbeddedWebApplicationContext : Refreshing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWeb ApplicationContext@1c5f743: startup date [Thu May 29 09:59:31 IST 2014]; root of context hierarchy 2014-05-29 09:59:34.295 INFO 2756 --- [ main] .t.TomcatEmbeddedServletContainerFactory : Server initialized with port: -1 2014-05-29 09:59:34.748 INFO 2756 --- [ main] o.apache.catalina.core.StandardService : Starting service Tomcat 2014-05-29 09:59:34.748 INFO 2756 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet Engine: Apache Tomcat/7.0.52 2014-05-29 09:59:35.013 INFO 2756 --- [ost-startStop-1] o.a.c.c.C.[.[localhost].[/secure] : Initializing Spring embedded WebApplicationContext 2014-05-29 09:59:35.013 INFO 2756 --- [ost-startStop-1] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 3105 ms 2014-05-29 09:59:36.526 INFO 2756 --- [ost-startStop-1] o.s.s.web.DefaultSecurityFilterChain : Creating filter chain: org.springframework.security.web.util.matcher.AnyRequestM atcher@1, [org.springframework.security.web.context.request.async.WebAsyncManagerIntegrationFilter@167c6fd, org.springframework.security.web.context.SecurityContextPersistenceFilte r@139d115, org.springframework.security.web.header.HeaderWriterFilter@19d9c0d, org.springframework.security.web.csrf.CsrfFilter@1384ed5, org.springframework.security.web.authentica tion.logout.LogoutFilter@14189d0, org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter@2cd728, org.springframework.security.web.savedrequest.Request CacheAwareFilter@83de21, org.springframework.security.web.servletapi.SecurityContextHolderAwareRequestFilter@1b2380e, org.springframework.security.web.authentication.AnonymousAuthe nticationFilter@39452f, org.springframework.security.web.session.SessionManagementFilter@154c054, org.springframework.security.web.access.ExceptionTranslationFilter@5db9eb, org.springframework.security.web.access.intercept.FilterSecurityInterceptor@1353154] 2014-05-29 09:59:36.589 INFO 2756 --- [ost-startStop-1] o.s.b.c.e.ServletRegistrationBean : Mapping servlet: 'dispatcherServlet' to [/] 2014-05-29 09:59:36.604 INFO 2756 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean : Mapping filter: 'springSecurityFilterChain' to: [/*] 2014-05-29 09:59:36.604 INFO 2756 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean : Mapping filter: 'hiddenHttpMethodFilter' to: [/*] 2014-05-29 09:59:37.213 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/**/favicon.ico] onto handler of type [class org.springframewor k.web.servlet.resource.ResourceHttpRequestHandler] 2014-05-29 09:59:37.415 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/hello] onto handler of type [class org.springframework.web.ser vlet.mvc.ParameterizableViewController] 2014-05-29 09:59:37.415 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/home] onto handler of type [class org.springframework.web.serv let.mvc.ParameterizableViewController] 2014-05-29 09:59:37.415 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/login] onto handler of type [class org.springframework.web.ser vlet.mvc.ParameterizableViewController] 2014-05-29 09:59:37.415 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Root mapping to handler of type [class org.springframework.web.servlet.mvc.Param eterizableViewController] 2014-05-29 09:59:37.431 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/**] onto handler of type [class org.springframework.web.servle t.resource.ResourceHttpRequestHandler] 2014-05-29 09:59:37.431 INFO 2756 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/webjars/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 2014-05-29 09:59:37.805 INFO 2756 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup 2014-05-29 09:59:37.868 INFO 2756 --- [ main] s.t.spring.security.config.Application : Started Application in 7.551 seconds (JVM running for 9.08)
