springboot中Applicationrunfailed的报错

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatServletWebServerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/ServletWebServerFactoryConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: ContextPath must start with '/' and not end with '/'

根据报错，发现是上下文路径缺少了“/”这个小细节一定要注意
