java - Springboot findBy List hibernate @Query

Question

我的实体如下所示：

@Entity
public class Specialist {
    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    String accountId;
    @NotNull(message = "Province may not be blank")
    Province province;
    @NotBlank(message = "City may not be blank")
    @Size(min = 3, max = 25, message = "City must be between 2 and 32 characters")
    String city;
    @JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY)
    @ElementCollection
    @Column(name = "profession", nullable = false)
    List<String> professions;
}

在存储库中，我想创建一种方法，该方法按以下规则按省，市和专业来寻找专家：


如果省，市和专业是空的，则返回所有专家
如果只有一个省是空的，则按城市和专业归还专家
如果只有一个城市是空的，则按省和专业返回专家
如果只有专业是空的，则按省市归还专家
如果省份和专业是空的，则按城市返回专家
如果城市和职业为空，则按省返回专家
如果省市是空的，则按专业归还专家


第二个需要注意的方面是职业可能有几个项目，例如水管工和自动或机械师，设计师，电工。

我的问题是如何遍历列表中的所有内容以找到特定的专家。

例如，如果我在邮递员3中创建具有以下专业的专家：


专业：[“水管工”，“自动”，“设计师”]
专业：[“设计师”]
专业：[“水管工”，“电工”]


并作为查询参数中的一个参数使用？professions = electrician，automatic，那么我将获得1,3位专家
如果？professions = designer，那么我将获得1,2位专家
如果？professions = gardener，那么我将收到专家空名单

我已经在存储库中实现以下方法：

    /*Find SPECIALIST by location and profession*/
        @Query("SELECT c FROM Specialist c WHERE (:province is null or c.province = :province)  and (:city is null or c.city = :city) and (:professions is null or c.professions in (:professions))")
    HashSet<Specialist> findSpecialistsByProvinceAndCityAndProfession(@Param("province")Province province, @Param("city")String city, @Param("professions") List<String> professions);

在serviceImpl中：

 @Override
    public HashSet<Specialist> findSpecialists(Province province, String city, List<String> profession){
        if(specialistRepo.count() == 0) throw new SpecialistNotFoundException("Any Specialist isn't exist");
        return specialistRepo.findSpecialistsByProvinceAndCityAndProfession(province,city,profession);
    }

并在控制器中：

@GetMapping("/get")
    public HashSet<Specialist> getSpecialistsByProvinceAndCityAndProfession(@RequestParam(value = "province",required = false) Province province,
                                                                            @RequestParam(value = "city",required = false)String city,
                                                                            @RequestParam(value = "profession", required = false) List<String> profession){
        return specialistService.findSpecialists(province,city,profession);
    }

如果我在邮递员中使用GET方法，那么我会收到此错误：

Answer 1

你可以尝试下面的答案

/*Find SPECIALIST by location and profession*/
@Query("SELECT c FROM Specialist c WHERE (c.province = :province) and (c.city = :city) and (c.professions in (:professions))")
    HashSet<Specialist> findSpecialistsByProvinceAndCityAndProfession(@Param("province")Province province, @Param("city")String city, @Param("professions") List<String> professions);
