CrudRepository throwing data mismatch on user login - spring-boot

Question

I am trying to set up a user endpoint for my webapp. (/user/{id})
i have a thymeleaf login form that calls a getUser endpoint which scans the user database for user by email and password. once it finds the user, it redirects to /user/{id}. inside the request mapping for /user/{id} it uses the UsersService to call the UserRepository which calls findById(String string).
the value of the id is a long. the crud repository has a method findById(String string) and it should map it to a long since its defined in the wildcard as a type.
I'm feeding the method a string as it's telling me that its an incorrect data type.
how do i query for user by id? why is it throwing this incompatible type error?
// thymeleaf form with get to /user/getUser endpoint
<form action="#" method="GET" th:action="#{/user/getUser}" th:object="${loginRequestModel}">
<p>Email: <input th:field="*{email}" type="text"/></p>
<p>Password: <input th:field="*{password}" type="text"/></p>
<p><input type="submit" value="Submit"/> <input type="reset" value="Reset"/></p>
</form>
// controller class with request mapping to /user
#GetMapping(value = "/{id}")
#ResponseBody
public String userUploads(#PathVariable("id") String id) {
log.info("userUploads endpoint called<<");
String returnValue;
try {
UserEntity userEntity = usersService.getUserById(id);
returnValue = "this account belongs to: " +
userEntity.getFirstName() + userEntity.getLastName();
log.info("returning new response entity<<");
return returnValue;
} catch (Exception e){
e.printStackTrace();
}
return "Couldn't load profile!";
}
#GetMapping("/getUser")
public String getUser(#ModelAttribute LoginRequestModel loginRequestModel) {
String userEmail = loginRequestModel.getEmail();
UserEntity userEntity = usersService.getUserDetailsByEmail(userEmail);
String id = String.valueOf(userEntity.getId());
return "redirect:/user/" + id;
}
// UsersService which contains the autowired CrudRepository
#Override
public UserEntity getUserDetailsByEmail(String email) {
return userRepository.findByEmail(email);
}
#Override

return userRepository.findById(userId);
}
// crud repository
import org.springframework.data.repository.CrudRepository;

Answer 1

Because the field id in your Entity class is type Long and the function in your controller in type String and also the parameter id in the function findUserById in UserService also type String too !
#GetMapping(value = "/{id}")
#ResponseBody
public String userUploads(#PathVariable("id") String id) {
// ...
}
SOLUTION : modify your Pathvariable id in the Controller to Long. and modify the related function used with that controller too (ex : userService ...)
#GetMapping(value = "/{id}")
#ResponseBody
public String userUploads(#PathVariable("id") Long id) {
// ...
}
