I am taking a REST api that works in Spring and trying to get it working with Spring boot 2.7.3 java 11 This code works in Spring and I can make CRUD calls to the api, but I get the below error using the same entity class, db, service and dao in boot. The paths in the annotations are correct in that the files exist there. Using the bean actuator, I can see the user entity is not listed.
When I make a call to the endpoint, java throws a not an entity error
java.lang.IllegalArgumentException: Not an entity: class com.test.user.entity.User.
I've looked through several SO questions, but nothing has worked

CodePudding user response：
The entity package com.test.user.entity is missing in your @EntityScan(basePackages = {"com.test.entity"}) annotation. Either fix the current base package or add the other base package to the annotation using
@EntityScan(basePackages = {"com.test.entity", "com.test.user.entity"})
When the entity package resides in the @SpringBootApplication(scanBasePackages = {"com.test.user"}), the entity scan annotation can be removed.
