通过打断点发现TomcatService的host的state是SOPPED状态,所以抛出了[failed to start]这个异常,但是为什么是SOPPED状态的原因并没有发现
解决方案:不用Springboot内嵌的Tomcat,使用本地Tomcat启动
发现堆栈信息与之前有些不一样,多了具体的异常报错
Caused by: java.lang.IllegalArgumentException: The servlets named [A_Servlet] and [B_Servlet] are both mapped to the url-pattern [/status.ci] which is not permitted
两个类继承了同一个Servlet,改掉之后启动正常
