java - tomcat应用程序已启动但立即销毁

Question

我已经在我的 Linux 盒子中部署了我的应用程序。我正在使用简单的 apache tomcat 7 版本。我可以看到我的 tomcat 上下文已初始化 但初始化后立即，上下文被破坏。我没有在日志文件中看到任何异常发生。

Answer 1

您的@Configuration类中是否定义了特定于配置文件的配置，例如

 @Configuration
 public class MyConfig {

   @Configuration
   @Profile(value="dev")
   public static class DevConfiuration {
        @Bean
        ///some bean methods here
   }
 } 

如果没有，请尝试完全删除以下配置文件标签并查看它是否已部署。

  <context-param>  
     <param-name>spring.profiles.active</param-name>  
     <param-value>dev</param-value>  
 </context-param>  
 <context-param>  
     <param-name>spring.profiles.default</param-name>  
     <param-value>dev</param-value>  
 </context-param>
 <context-param>  
     <param-name>spring.liveBeansView.mbeanDomain</param-name>  
     <param-value>dev</param-value>  
 </context-param>
