Spring Boot - 应用程序无法使用类路径启动

Question

多么美好的一天，不是吗？

我希望这个社区的人能帮助我。

Tomcat 版本 7，小服务程序 API 3.0

我喜欢使用 .war 在 tomcat 中启动我的 Spring Boot 项目。这是我的 spring boot 应用程序代码:

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);
    }


}

我需要在哪里设置类路径？我以为我不需要设置任何 .xml 文件。

谢谢!

此错误背后的原因之一是该端口已分配给其他人。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//你可以写任何你想要的端口
