Question

问题

我必须按姓名搜索用户，联系任何用户类型，即如果他输入姓名，他只获取姓名，如果他键入联系人，他只会联系而不是我获得所有用户结果。 < / p>

解决方案 -

第一种方法

我已经使用spring数据应用或查询了findByNameOrContactOrLocation等MongoDb.Below是我的代码。

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);

}

输入提供

{
"searchKey": "98111648642"
}

预期输出

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

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

**2nd Approach**

1）我可以检查数据是来自用户设置还是设置随机数据。虽然我还没有实现它。我正在寻找替代方法。

任何人都可以指导我做错了什么或任何替代方法吗？

Answer 1

在您的案例中，

findByFirstNameOrContactOrLocationOrGenderInOrProfessionInOrInterestsInOrHeightOrAgeBetween有效意味着

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

由于您使用OR，它将获取所有记录。因为可能有一些属性对所有记录都是null 正如@Niel建议的那样，拥有如此长的查询语句并不是一个好主意。 spring-data-mongodb可以解决这个问题，但你会失去清晰度。

无法使用spring-data Mongodb获得预期输出
