[JWT] SpringBoot中遇到的问题 Unable to load class named [io.jsonwebtoken.impl.crypto.MacProvider] from the thread context, current, or system/application ClassLoaders

I got this error message while login in to the spring-boot application from postman. I used JWT webtoken for authentication and authorization. Please help on this.

io.jsonwebtoken.lang.UnknownClassException: Unable to load class named [io.jsonwebtoken.impl.crypto.MacProvider] from the thread context, current, or system/application ClassLoaders.  All heuristics have been exhausted.  Class could not be found.  Have you remembered to include the jjwt-impl.jar in your runtime classpath?
