使用spring-data Mongodb无法获得预期的输出

Question

Problem

I have to search user by name,contact whatever user types ie if he types name he gets name only and if he type contact he gets contact only etc instead I am getting all user results.

Solution -

1st Approach

I have applied or query ie findByNameOrContactOrLocation etc using spring data MongoDb.Below is my code.

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);

}

Input Supplied

{
"searchKey": "98111648642"
}

Output Expected

**2nd Approach**

1)I can check if the data is coming from user set it or set a random data.Though I have not implemented it.I am looking for alternate approach for this.

Can anyone guide for what am I doing wrong or any alternate approach?

Answer 1

findByFirstNameOrContactOrLocationOrGenderInOrProfessionInOrInterestsInOrHeightOrAgeBetween in your case effectively means

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

Since you are using OR, it will fetch all the records. Because there might be some property which is null for all the records.
As @Niel suggested, it is not a good idea to have such a long query statement. spring-data-mongodb can handle this, but you will lose clarity.
