使用spring-data Mongodb無法獲得預期的輸出

Question

問題

我必須按名稱搜索用戶，聯系任何用戶類型，即，如果他鍵入名稱，則他僅獲得名稱；如果他鍵入聯系人，則僅獲得聯系人，等等， 而是獲得所有用戶結果。

解決方案-

第一種方法

我已經使用彈簧數據MongoDb應用或查詢了findByNameOrContactOrLocation等，下面是我的代碼。

public class Search {
private String searchKey;
private double[] location;
private List<Gender> gender;
private List<String> profession;
private List<INTERESTS> interests;
private int minAge;
private int maxAge;
private double[] height;



 @PutMapping(value = "/searchByEndUser")
ApiResponse<List<Employee>> searchEndUserBasedOnKeyWord(@RequestBody Search params) {
    return ApiResponse.success().object(employeeService.getByWord(params));
}


@Service
public class EmployeeServiceImpl implements EmployeeService {

@Override
public List<Employee> getByWord(Search params) {
    return employeeRepository.findByFirstNameOrContactOrLocationOrGenderInOrProfessionInOrInterestsInOrHeightOrAgeBetween(params.getSearchKey(), params.getSearchKey(), params.getLocation(), params.getGender(), params.getProfession(), params.getInterests(), params.getHeight(), params.getMinAge(), params.getMaxAge());
}

public interface EmployeeRepository extends MongoRepository<Employee, String> {
List<Employee> findByFirstNameOrContactOrLocationOrGenderInOrProfessionInOrInterestsInOrHeightOrAgeBetween(String searchKey, String searchKey1, double[] location, List<Gender> gender, List<String> profession, List<INTERESTS> interests, double[] height, int minAge, int maxAge);

}

輸入提供

{
"searchKey": "98111648642"
}

預期產量

 {
  "createdBy": "anonymousUser",
  "lastModifiedBy": "anonymousUser",
  "version": 0,
  "createdAt": 1510303944245,

  "referredUserId": null,
  "choice": null,
  "id": "5a0568c879eb192b872592b3"
 }
 ]
 }

下面我只顯示2個輸出

顯示的輸出

**2nd Approach**

1）我可以檢查數據是來自用戶設置的還是設置隨機數據的，盡管我尚未實現它，但我正在尋找替代方法。

誰能指導我做錯了什么或任何其他方法？

Answer 1

在您的情況下，findByFirstNameOrContactOrLocationOrGenderInOrProfessionInOrInterestsInOrHeightOrAgeBetween有效意味着

Get_me_documents_where {
    firstname : "98111648642"
      or
     contact : "98111648642"
      or
    location : null
      or 
    gender : null
      or
   ......
}

由於您使用的是OR，因此它將獲取所有記錄。 因為可能有些屬性對於所有記錄都為空。
正如@Niel所建議的，擁有這么長的查詢語句不是一個好主意。 spring-data-mongodb可以解決這個問題，但是您會變得不清楚。
