CodePudding user response：
See What is a stack trace, and how can I use it to debug my application errors?.
The stacktrace you get describes the error:
Caused by: org.springframework.beans.NotReadablePropertyException: Invalid property 'password' of bean class [com.booking.system.entity.Member]: Bean property 'password' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
