I am new to JWT. I create my own microservice and want to introduce JWT authentication. I have one website that issues a token and in the other I want to check the correctness of this token. I want to do this without connecting the second site to db. This approach seems to me appropriate and best for user data.
I have following payload of token:
{
"sub": "Marek",
"auth": [
{
"authority": "ROLE_USER"
}
],
"iat": 1574091010,
"exp": 1574091210
}
Its my code:

#Autowired

http.exceptionHandling().accessDeniedPage("/login");
http.apply(new JWTConfigurer(jwtTockenCreator));

In Eclipse doesn't give any errors. That's why I don't know what I'm doing wrong
when I want to call / user / addUser and add a new user nothing happens. In the User service I call, I have a function responsible for adding users and it works correctly when I refer to it directly. And if I want to do it through my Rest Api it doesn't work anymore. And it is my problem that I do not know what can happen because I have no mistake. I remind you that I am still learning and I am asking for understanding

I have implemented a custom exception handler that handles all the exception that I am throwing:
#ControllerAdvice
public class AppExceptionHandler {
#ExceptionHandler(value = {UserServiceException.class})
public ResponseEntity<Object>handleUserServiceException(
UserServiceException ex, WebRequest request){
ErrorMessage errorMessage = new ErrorMessage(new Date(), ex.getMessage());
return new ResponseEntity<>(errorMessage, new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR );
}
//A universal exception handling method
#ExceptionHandler(value = {Exception.class})
public ResponseEntity<Object>handleUserOtherExceptions(Exception ex, WebRequest request){
ErrorMessage errorMessage = new ErrorMessage(new Date(), ex.getMessage());
return new ResponseEntity<>(errorMessage, new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR );
}
}
The Universal exception handler method doesn't gets called for 403 status response, the response body is empty but I want to see a response body.

Below is my postman response (As you can see the body is empty
I want Spring to handle all other exceptions by calling the overriding #ExceptionHandler I have written in the above AppExceptionHandler class.
As you can see the response body is empty. How do I return the default or custom object for response body?
Im not quite sure if this is what you are looking for, but If you want to somehow customize the messages from failed authentication have a look on AuthenticationEntryPoint like in https://www.baeldung.com/spring-security-basic-authentication. There you can react on the thrown exception and customize what message and codes to return.
I created a Spring Boot Rest Api with custom JWT authentication.
My problem is that when I'm sending for example a request with an expired, or invalid JWT token, I'm getting an exception like this:
com.auth0.jwt.exceptions.SignatureVerificationException: The Token's Signature resulted invalid when verified using the Algorithm: HmacSHA512
Which is obvoiusly OK, but the response body is empty and therefore the client has no clue why is the 403 error.
Problem is same with Spring's BadCredentials Exception etc...
How do I convert these exceptions into custom error responses instead of "403 forbidden"?

If you are extending your JWTAuthenticationFilter from AbstractAuthenticationProcessingFilter, you can override unsuccessfulAuthenticationlike below:
#Override
protected void unsuccessfulAuthentication(
HttpServletRequest request, HttpServletResponse response, AuthenticationException failed)
throws IOException, ServletException {
SecurityContextHolder.clearContext();
failureHandler.onAuthenticationFailure(request, response, failed);
}
Now, as you can see, I've delegated the failure processing to my failureHandler which is of type org.springframework.security.web.authentication.AuthenticationFailureHandler.
For this you need to register your custom failure handler. You can do that by implementing your handler from org.springframework.security.web.authentication.AuthenticationFailureHandler and override onAuthenticationFailure, with checking the instance of your exception thrown from JWTAuthenticationFilter, like this:
#Component
public class MyAuthFailureHandler implements AuthenticationFailureHandler {
private final ObjectMapper mapper;
#Autowired
public MyAuthFailureHandler(ObjectMapper mapper) {
this.mapper = mapper;
}
#Override
public void onAuthenticationFailure(
HttpServletRequest request, HttpServletResponse response, AuthenticationException e)
throws IOException, ServletException {
response.setStatus(HttpStatus.UNAUTHORIZED.value());
response.setContentType(MediaType.APPLICATION_JSON_VALUE);
if (e instanceof BadCredentialsException) {
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(
"Invalid username or password", ErrorCode.AUTHENTICATION, HttpStatus.UNAUTHORIZED));
} else if (e instanceof JwtExpiredTokenException) {
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(
"Token has expired", ErrorCode.JWT_TOKEN_EXPIRED, HttpStatus.UNAUTHORIZED));
} else if (e instanceof AuthMethodNotSupportedException) {
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(e.getMessage(), ErrorCode.AUTHENTICATION, HttpStatus.UNAUTHORIZED));
} else if (e instanceof TokenEncryptionException) {
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(e.getMessage(), ErrorCode.AUTHENTICATION, HttpStatus.UNAUTHORIZED));
} else if (e instanceof InvalidJwtAuthenticationTokenException) {
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(e.getMessage(), ErrorCode.AUTHENTICATION, HttpStatus.UNAUTHORIZED));
}
mapper.writeValue(
response.getWriter(),
ErrorResponse.of(
"Authentication failed", ErrorCode.AUTHENTICATION, HttpStatus.UNAUTHORIZED));
}
I am new to Springboot and im trying to filter requests through a Zuul API gateway however i get the error below :
AnonymousAuthenticationToken cannot be cast to org.aacctt.ms.auth.security.JWTAuthentication
When i put a breakpoint i get a null header/token string value when the request reaches the authentication service from zuul gateway, this happens for protected requests that require an authorization token.
My aim is to be able to verify the token sent by clients so that i can allow the client's request to protected endpoints or reject it.
Im not sure what im doing wrong here is my code:

The issue is the sensitive header, Authorization is sensitive header by default in Zuul, you just need to override the sensitive headers.
zuul:
sensitive-headers:
-
By setting this property in Zuul gateway application.yml it route request to auth service with the Authorization header

I want create endpoint login with using spring security (basic authentication).
What I want? If you provide correct data, response will be 200 or 202 and when bad data response will be HTTP 400.

try {

else if(client.getRole().equals("ADMIN"))
return new ResponseEntity<String>(JSONObject.quote(client.getRole()),HttpStatus.ACCEPTED);
else
throw new Exception();
} catch (Exception e) {
return new ResponseEntity<String>(HttpStatus.UNAUTHORIZED);
}
}

else {
return new org.springframework.security.core.userdetails.User(client.getLogin(), client.getPassword(), grantedAuthorities);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;

Now if I provide first bad password, all is ok, in response is HTTP 401. But if first good data, and then other (bad), all time in response is 200 or 202.
Who will tell me what is wrong here?
I am writing rest service with json. For backend I use Spring Security. I have form witch sends with ajax rest object as follow:
{email: "admin", password: "secret"}
Now on the server I have configuration as follow:
#Configuration
#EnableWebSecurity
#ComponentScan("pl.korbeldaniel.cms.server")
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private RestAuthenticationEntryPoint restAuthenticationEntryPoint;
#Autowired
private RestAuthenticationSuccessHandler authenticationSuccessHandler;
#Autowired
private RestAuthenticationFailureHandler authenticationFailureHandler;
#Bean
JsonAuthenticationFilter jsonAuthenticationFilter() throws Exception {
JsonAuthenticationFilter filter = new JsonAuthenticationFilter();
filter.setAuthenticationManager(authenticationManagerBean());
System.out.println("jsonAuthenticationFilter");
return filter;
}
#Bean
public RestAuthenticationSuccessHandler mySuccessHandler() {
return new RestAuthenticationSuccessHandler();
}
#Override
#Autowired
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("admin").password("secret").roles("ADMIN");
// auth.jdbcAuthentication().
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.addFilterBefore(jsonAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
http.csrf().disable();//
http.exceptionHandling().authenticationEntryPoint(restAuthenticationEntryPoint)//
.and().authorizeRequests()//
.antMatchers("/").permitAll()//
.antMatchers("/services/anonymous/**").permitAll()//
.antMatchers("/services/authenticated/**").authenticated()//
.and().formLogin().loginProcessingUrl("/services/anonymous/loginService/login").usernameParameter("email").passwordParameter("password")//
.successHandler(authenticationSuccessHandler)//
.and().logout().logoutUrl("/services/anonymous/loginService/logout");
// http.httpBasic();
}
}
Problem is that spring security demands from me to send credentials as body, but I would like to spring accept my Json object.
So I've wrote my own authentication filter base on this:
#Component
public class JsonAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
private boolean postOnly;
#Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
System.out.println("attemptAuthentication");
if (postOnly && !request.getMethod().equals("POST")) {
throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
}
UsernamePasswordAuthenticationToken authRequest = this.getUserNamePasswordAuthenticationToken(request);
// Allow subclasses to set the "details" property
setDetails(request, authRequest);
return this.getAuthenticationManager().authenticate(authRequest);
}
/**
* #param request
* #return
*/
private UsernamePasswordAuthenticationToken getUserNamePasswordAuthenticationToken(HttpServletRequest request) {
// TODO Auto-generated method stub
System.out.println(request);
return null;
}
}
But unfortunatelly this filter seems to not work.
When I send ajax post request from login form, I am getting 302 Found and then I am getting this:
Remote Address:127.0.0.1:8080
Request URL:http://localhost:8080/cms/login?error
Request Method:GET
Status Code:404 Not Found
Like there fail to validate user credential (cause form body is empty and credentials goes as json), and then it redirect to login?error which doesn't exist cause I've my own login form.
Please help.

Well, it must not work until you write the getUserNamePasswordAuthenticationToken body.
Actually, you must read the request body of the HttpServletRequest, parse it through Jackson or any other mapping way and create with it the UsernamePasswordAuthenticationToken.
Using Jackson (choose the right version depending on your Spring version), I would create a simple bean like this:
#JsonIgnoreProperties(ignoreUnkown=true)
public LoginRequest{
private String email;
private String password;
// getters & setters
}
The use it to map it the request body:
private UsernamePasswordAuthenticationToken getUserNamePasswordAuthenticationToken(HttpServletRequest request) throws IOException{
StringBuffer sb = new StringBuffer();
BufferedReader bufferedReader = null;
String content = "";
LoginRequest sr = null;
try {
bufferedReader = request.getReader()

P.D. Yo must use Post, you will never be able to post a request-body using GET
You can extend and override WebSecurityConfigurerAdapter
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.addFilter(new UserNamePasswordAuthFilter(authenticationManager(), userRepo))
.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest()
.authenticated()
.and()
.httpBasic();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(daoAuthenticationProvider());
}
#Bean
public DaoAuthenticationProvider daoAuthenticationProvider() {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setUserDetailsService(userDetailsService); // custom user service
provider.setPasswordEncoder(passwordEncoder); // custom password encoder
return provider;
}
Then you can define a filter for authentication and optionally you can override successful login behavior.
public class UserNamePasswordAuthFilter extends UsernamePasswordAuthenticationFilter {
private final AuthenticationManager authManager;
private final AecUserRepo userRepo;
public UserNamePasswordAuthFilter(AuthenticationManager authManager, AecUserRepo userRepo) {
super();
this.authManager = authManager;
this.userRepo = userRepo;
}
#Override
public Authentication attemptAuthentication(HttpServletRequest request,
HttpServletResponse response) throws AuthenticationException {
try {
// Get username & password from request (JSON) any way you like
UsernamePassword authRequest = new ObjectMapper()
.readValue(request.getInputStream(), UsernamePassword.class);
Authentication auth = new UsernamePasswordAuthenticationToken(authRequest.getUsername(),
authRequest.getPassword());
return authManager.authenticate(auth);
} catch (Exception exp) {
throw new RuntimeException(exp);
}
}
#Override
protected void successfulAuthentication(HttpServletRequest request,
HttpServletResponse response, FilterChain chain, Authentication authResult)
throws IOException, ServletException {
if (logger.isDebugEnabled()) {
logger.debug("Authentication success. Updating SecurityContextHolder to contain: "
+ authResult);
}
// custom code
SecurityContextHolder.getContext().setAuthentication(authResult);
}
}
