Equals的用法

2018-10-28 13:15 更新


表person对应的model类:

@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
}
数据库访问PersonRepository类:

public interface PersonRepository extends JpaRepository<Person, Long>, JpaSpecificationExecutor<Person> {
}
查询昵称等于"dog",姓名等于"Jack"、"Eric"或者为空(null),并且公司也为空的人。

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

    return personRepository.findAll(specification); 
}
