Spring Boot - 應用程序未能以類路徑啓動

真是一個美好的一天，不是嗎？Spring Boot - 應用程序未能以類路徑啓動

我希望這個社區的某個人能幫助我。

的Tomcat版本7， Servlet API的3.0

我喜歡用一個.war開始我春季啓動項目在Tomcat。我的繼承人彈簧引導應用的代碼：

主類

@Configuration 
@EnableAutoConfiguration 
@ComponentScan(basePackages = "com.###.dashboard") 
@EnableJpaRepositories 
@EntityScan(basePackages = "com.###.dashboard.domain") 
public class Dashboard extends SpringBootServletInitializer { 

    public static void main(String[] args) { 
     SpringApplication.run(new Object[] {Dashboard.class}, args);  
    } 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(Dashboard.class); 
    } 


}

POM的Tomcat /彈簧引導的

我需要設置類路徑嗎？我以爲我不需要設置任何.xml文件。

謝謝！

** java.lang.OutOfMemoryError：PermGen space ** - 您需要爲運行Tomcat的JVM分配更多內存。搜索這個錯誤，我相信你會找到答案 – 2014-12-04 13:29:29

-1

此錯誤背後的原因之一是該端口已被分配給其他人。您可以通過更改端口地址來測試它。只需在資源目錄下添加一個application.propeties。然後添加以下內容 server.port：9000 //您可以編寫任何您想要的端口
