表person對(duì)應(yīng)的model類(lèi)：

@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(kù)訪問(wèn)PersonRepository類(lèi)：

public interface PersonRepository extends JpaRepository<Person, Long>, JpaSpecificationExecutor<Person> {
}

public List<Person> findAll(SearchRequest request) {
    Specification<Person> specification = new Specifications<Person>()
            .ne("nickName", "dog")
            .ne(isNotBlank(request.getName()), "name", "Jack", "Eric")
            .ne("company", null) //or ne("company", (Object) null)
            .build();

    return personRepository.findAll(specification); 
}
