Spring Boot - 应用程序未能以类路径启动

真是一个美好的一天，不是吗？Spring Boot - 应用程序未能以类路径启动

我希望这个社区的某个人能帮助我。

的Tomcat版本7， Servlet API的3.0

我喜欢用一个.war开始我春季启动项目在Tomcat。我的继承人弹簧引导应用的代码：

主类

@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 /弹簧引导的

我需要设置类路径吗？我以为我不需要设置任何.xml文件。

谢谢！

** java.lang.OutOfMemoryError：PermGen space ** - 您需要为运行Tomcat的JVM分配更多内存。搜索这个错误，我相信你会找到答案 – 2014-12-04 13:29:29

-1

此错误背后的原因之一是该端口已被分配给其他人。您可以通过更改端口地址来测试它。只需在资源目录下添加一个application.propeties。然后添加以下内容 server.port：9000 //您可以编写任何您想要的端口
