表person對應(yīng)的model類:
@Entity
@Table(name = "person")
public class Person {
@Id
@GeneratedValue
private Long id;
private Integer age;
private String name;
@Column(name = "nick_name")
private String nickName;
private String company;
private Date birthday;
// getter and setter
}
數(shù)據(jù)庫訪問PersonRepository類:public interface PersonRepository extends JpaRepository<Person, Long>, JpaSpecificationExecutor<Person> {
}
查詢不在某個范圍內(nèi)的人。public List<Person> findAll(SearchRequest request) {
Specification<Person> specification = new Specifications<Person>()
.notIn(isNotBlank(request.getName()), "name", request.getNames().toArray()) // or notIn("Jack", "Eric")
.build();
return personRepository.findAll(specification);
}
