Filed to create query for method public abstract

I created a login user using controller, user, repository and service in my project. In controller, if email id and password are not null then login otherwise throw an exception "User Not Exist". I am getting the bellow error, can you help me to fix this issue?

Error:

Error creating bean with name 'registrationRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract com.adventure.network.model.User com.adventure.network.repository.RegistrationRepository.findByEmailIdAndByPassword(java.lang.String,java.lang.String)! No property byPassword found for type User!

Controller:

@RestController
public class RegistrationController {
@Autowired
private RegistrationService service;
@PostMapping("/login")
public User loginUser(@RequestBody User user) throws Exception {
String tempEmailId = user.getEmailId();
String tempPassword = user.getPassword();
User userObject = null;
if(tempEmailId!=null && tempPassword!=null) {
userObject = service.fetchUserByEmailIdByPassword(tempEmailId, tempPassword);	
}
if(userObject == null) {
throw new Exception("User is not exict");
}
return userObject;
}

Service:

@Service
public class RegistrationService {
@Autowired 
private RegistrationRepository repo;
public User fetchUserByEmailIdByPassword(String email, String password) {
return repo.findByEmailIdAndByPassword(email, password);
}
}

Repository:

public interface RegistrationRepository extends JpaRepository<User, Integer> {
public User findByEmailIdAndByPassword(String emailId, String password);
}

As per your error message No property byPassword found for type User!, it is looking for the property named byPassword you need to change to andPassword in the repository as shown below.

public interface RegistrationRepository extends JpaRepository<User, Integer> {
public User findByEmailIdAndPassword(String emailId, String password);
}

Spring will parse every property mentioned after by, you need by only at the start of the method

You can also change the name to be more readable as

public interface RegistrationRepository extends JpaRepository<User, Integer> {
public User findUserByEmailIdAndPassword(String emailId, String password);
}
