IDEA spring boot 启动报错

Question

完全是按造这个教程, 学习的教程地址:2小时学会Spring Boot  https://www.imooc.com/video/13590

java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]]

然后自动创建项目的这里面很多飘红,IDEA 的新版的,java1.8 / maven3.5
