通过字段中的设置进行补丁映射对象更新的最佳方法

Question

在这样的对象上进行补丁映射的最佳方法是什么：

@Data
public class UnifiedOfferEntity {
    private String companyName;
    private String city;
    private String title;
    private Set<SkillEntity> skills;

}

在实体中，我有很多经营。我做了更新的方法，以发送映射＆lt; fieldName，value＆gt;它可以正常工作，直到我试图将其设置为请求主体为止。

public UnifiedOfferEntity patchEntity(String id, Map<Object, Object> fields) {
    UnifiedOfferEntity unifiedOfferEntity = getEntityById(id);
    fields.forEach((key, value) -> {
        Field field = ReflectionUtils.findField(UnifiedOfferEntity.class, (String) key);
        field.setAccessible(true);
        ReflectionUtils.setField(field, unifiedOfferEntity, value);
    });
    return unifiedOfferEntity;
}

我得到：

java.lang.IllegalArgumentException: Can not set java.util.Set field com.example.jobfinder.entity.UnifiedOfferEntity.seniority to java.util.ArrayList

Answer 1

您是否在这种方法中考虑过：

 public UnifiedOfferEntity patchEntity(String id, Map<Object, Object> fields) {
        UnifiedOfferEntity unifiedOfferEntity = getEntityById(id);
        enhanceUnitedOfferEntity(unifiedOfferEntity,fields);
    
        return unifiedOfferEntity;
    }

该方法将根据键作为常数手动填充OBJET ..或另一个对象...

 private void enhanceUnitedOfferEntity(UnifiedOfferEntity unifiedOfferEntity, Map<Object, Object> fields){
    fields.forEach((k, v) ->
      switch(k) {
        case "COMPANY_NAME":
          unifiedOfferEntity.setCompanyName(v);
        case "CITY":
          unifiedOfferEntity.setCity(v);
        case "TITLE":
          unifiedOfferEntity.setTitle(v);
          break;
        case "SKILLS":
          unifiedOfferEntity.setSkills(v);
          break;
        default:
      });
    }
