我试图按照本教程创建一个简单的REST Web服务,但我可以在Tomcat中部署它,它抛出一个异常:
FAIL - Application at context path /restful could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/restful]]
我看了看周围的解决方案,发现这个问题 ,这一个 ,他们让我觉得这是一个servlet的映射问题但是我不知道如何解决它!
这是我的日志文件:
