NotIn的用法

2018-10-28 13:14 更新


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); 
}
