Hibernate query page As long as there is a field null to find the entire data is null

pageable pageable = this.getpageable (querydto); Page<prpdexch> Page2 = Prpdexchdao.findall (pageable);

Query results by postman:

{"ResultCode": "0000", "resultmsg": "Success", "TransactionID": "", "Resultobj": {"content": [NULL, NULL, NULL, NULL, NULL], "totalcount": +, "pages": 5}}

Finally, navigate to:

The @idclass annotation on the class refers to itself, which means that all of its fields are treated as primary keys, so there is a null in the field causing an error.

before:

@Entity @table (name = "Prpdexch") @IdClass (prpdexch.class) public class Prpdexch implements BaseEntity, Serializable {... }

After the change

@Entity @table (name = "Prpdexch") @IdClass (prpdexchkey.class) public class Prpdexch implements BaseEntity, Serializable { ...}

Careless error ....
