我有一个 Springboot 应用程序，我想用嵌入式 tomcat 容器运行它。
我在 Debian 系统上使用它(在我的 Mac 上一切顺利)。 我正在使用 tomcat 8.0.29。 Tomcat 运行正常。 当我启动我的应用程序时，我得到了这个异常。这不是完整的堆栈跟踪，在这部分之后，它是关于自动连接所有可能的事情的异常..

这是应用类
@SpringBootApplication
@ComponentScan("it.besmart")
public class StartServer extends SpringBootServletInitializer{
public static void main(String[] args){
SpringApplication.run(StartServer.class, args);
}
@Override
protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
return application.sources(StartServer.class);
}
}
可能是哪个问题？
最佳答案
添加这个你的pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
并重构StartServer并删除这个@ComponentScan("it.besmart")因为@SpringBootApplication也提供别名来自定义属性@EnableAutoConfiguration 和 @ComponentScan
