What I am doing is, I am sending a login request with userid and the password and then reading values in authentication filter like this.
#Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
try {
UserLoginRequestModel creds = new ObjectMapper().readValue(request.getInputStream(),
UserLoginRequestModel.class);
return getAuthenticationManager().authenticate(
new UsernamePasswordAuthenticationToken(creds.getUserid(), creds.getPassword(), new ArrayList<>()));
} catch (Exception e) {
throw new RuntimeException(e);
}
}
When I run this application in debug mode then I got to know that it's throwing the exception while mapping the value from the request to Object at this point.
UserLoginRequestModel creds = new ObjectMapper().readValue(request.getInputStream(),
UserLoginRequestModel.class);
Also, I am authentication the user using userid as a username and the implementation of findUserbyUsername().
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
{
UserEntity details = dataCallback.findByuserid(username);
if (details == null)
throw new UsernameNotFoundException("Invalid Username or Password.");
return new User(details.getUserId(), details.getEncryptedPassword(), true, true,
true, true, new ArrayList());
}
Please help me guys, I am stuck here for long because of that I am unable to make progress in my project! Let me know if you need anything else related to project configuration.

The problem is with the mapping from request to java class as you have mentioned:
UserLoginRequestModel creds = new ObjectMapper().readValue(request.getInputStream(),
UserLoginRequestModel.class);
Change it to:
Map<String, String> params = new HashMap<>();
Map<String, String[]> parameterMap = request.getParameterMap();
parameterMap.forEach((key,value) -> { params.put(key, value[0]); });
String json = String.format( "{ \"userid\" : \"%s\", \"password\" : \"%s\" }", parameterMap.get("userid")[0], parameterMap.get("password")[0]);
UserLoginRequestModel creds = new ObjectMapper().readValue(json, UserLoginRequestModel.class);
A little bit wordy but less magic and works :)
