I'm implementing JWT and Spring Security for authentication in my application.
I have 3 roles: Admin, Moderator and User.
For example, after logging with user role, I got the home page, but once I go to hit the user space by clicking on a button, I got:
2020-09-04 09:01:22.819 ERROR 10148 --- [nio-8080-exec-5] c.b.s.security.jwt.AuthEntryPointJwt : Unauthorized error: Full authentication is required to access this resource
the file webSecurityConfig.java is:
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
// securedEnabled = true,
// jsr250Enabled = true,
prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
UserDetailsServiceImpl userDetailsService;
@Autowired
private AuthEntryPointJwt unauthorizedHandler;
@Bean
public AuthTokenFilter authenticationJwtTokenFilter() {
return new AuthTokenFilter();
}
@Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
authenticationManagerBuilder.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests().antMatchers("/api/auth/**").permitAll()
.antMatchers("/api/test/**").permitAll()
.anyRequest().authenticated();
http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
}
}
The class AuthEntryPointJwt is:
@Component public class AuthEntryPointJwt implements AuthenticationEntryPoint {
private static final Logger logger = LoggerFactory.getLogger(AuthEntryPointJwt.class);
@Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
logger.error("Unauthorized error: {}", authException.getMessage());
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Error: Unauthorized");
}
}
The class AuthTokenFilter is:
public class AuthTokenFilter extends OncePerRequestFilter { @Autowired private JwtUtils jwtUtils;
@Autowired
private UserDetailsServiceImpl userDetailsService;
private static final Logger logger = LoggerFactory.getLogger(AuthTokenFilter.class);
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
try {
String jwt = parseJwt(request);
if (jwt != null && jwtUtils.validateJwtToken(jwt)) {
String username = jwtUtils.getUserNameFromJwtToken(jwt);
UserDetails userDetails = userDetailsService.loadUserByUsername(username);
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
userDetails, null, userDetails.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
SecurityContextHolder.getContext().setAuthentication(authentication);
}
} catch (Exception e) {
logger.error("Cannot set user authentication: {}", e);
}
filterChain.doFilter(request, response);
}
private String parseJwt(HttpServletRequest request) {
String headerAuth = request.getHeader("Authorization");
if (StringUtils.hasText(headerAuth) && headerAuth.startsWith("Bearer ")) {
return headerAuth.substring(7, headerAuth.length());
}
return null;
}
}
The class JwtUtils is:
@Component public class JwtUtils { private static final Logger logger = LoggerFactory.getLogger(JwtUtils.class);
@Value("${bezkoder.app.jwtSecret}")
private String jwtSecret;
@Value("${bezkoder.app.jwtExpirationMs}")
private int jwtExpirationMs;
public String generateJwtToken(Authentication authentication) {
UserDetailsImpl userPrincipal = (UserDetailsImpl) authentication.getPrincipal();
return Jwts.builder()
.setSubject((userPrincipal.getUsername()))
.setIssuedAt(new Date())
.setExpiration(new Date((new Date()).getTime() + jwtExpirationMs))
.signWith(SignatureAlgorithm.HS512, jwtSecret)
.compact();
}
public String getUserNameFromJwtToken(String token) {
return Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(token).getBody().getSubject();
}
public boolean validateJwtToken(String authToken) {
try {
Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(authToken);
return true;
} catch (SignatureException e) {
logger.error("Invalid JWT signature: {}", e.getMessage());
} catch (MalformedJwtException e) {
logger.error("Invalid JWT token: {}", e.getMessage());
} catch (ExpiredJwtException e) {
logger.error("JWT token is expired: {}", e.getMessage());
} catch (UnsupportedJwtException e) {
logger.error("JWT token is unsupported: {}", e.getMessage());
} catch (IllegalArgumentException e) {
logger.error("JWT claims string is empty: {}", e.getMessage());
}
return false;
}
}
The class AuthController is:
@CrossOrigin(origins = "*", maxAge = 3600) @RestController @RequestMapping("/api/auth") public class AuthController { @Autowired AuthenticationManager authenticationManager;
@Autowired
UserRepository userRepository;
@Autowired
RoleRepository roleRepository;
@Autowired
PasswordEncoder encoder;
@Autowired
JwtUtils jwtUtils;
@PostMapping("/signin")
public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest) {
System.out.println("---------------- auth 1 ");
Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(loginRequest.getUsername(), loginRequest.getPassword()));
SecurityContextHolder.getContext().setAuthentication(authentication);
String jwt = jwtUtils.generateJwtToken(authentication);
UserDetailsImpl userDetails = (UserDetailsImpl) authentication.getPrincipal();
List<String> roles = userDetails.getAuthorities().stream()
.map(item -> item.getAuthority())
.collect(Collectors.toList());
return ResponseEntity.ok(new JwtResponse(jwt,
userDetails.getId(),
userDetails.getUsername(),
userDetails.getEmail(),
roles));
}
@GetMapping("/user")
@PreAuthorize("hasRole('USER') or hasRole('MODERATOR') or hasRole('ADMIN')")
public String userAccess()
{
System.out.println("---------------- test User ");
return "User Content.";
}
}
The file application.properties, I put:
spring.datasource.url=...
spring.datasource.username=...
spring.datasource.password=...
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation= true
spring.jpa.properties.hibernate.dialect=...
spring.jpa.hibernate.ddl-auto=update
bezkoder.app.jwtSecret= bezKoderSecretKey
bezkoder.app.jwtExpirationMs= 86400000
In Browser console, I got that exception.
Could you please help me solving that issue ?. Big thanks.
You should comment @PreAuthorize("hasRole('USER') or hasRole('MODERATOR') or hasRole('ADMIN')").
Tell about the result ?.
