solution

Add no-argument and full-argument construction methods in the corresponding entity class

@NoArgsConstructor
@AllArgsConstructor

Reason: lack of no-argument constructor
SQL uses objects to receive return values, corresponding to the lack of no-argument constructor in JAVA Bean.
If you create a parameter-less constructor with incomplete parameters, lombok's @Data, the default no-argument constructor will be invalid, and you still need to join manually

It's over, sprinkle flowers, and leave a message if you have any questions.
