出现未经授权的错误：需要完全身份验证才能访问此资源

Question

我正在我的应用程序中实现JWT和Spring Security进行身份验证。

我有 3 个角色：管理员、主持人和用户。

例如，使用用户角色登录后，我得到了主页，但是一旦我通过单击按钮进入用户空间，我得到：

2020-09-04 09:01:22.819 ERROR 10148 --- [nio-8080-exec-5] cbssecurity.jwt.AuthEntryPointJwt：未经授权的错误：需要完全身份验证才能访问此资源

文件webSecurityConfig.java是：

@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);
    }
}

• AuthEntryPointJwt类是：

  @Component 公共类 AuthEntryPointJwt 实现 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");
    }
  

  }

• AuthTokenFilter类是：

  公共类 AuthTokenFilter 扩展了 OncePerRequestFilter { @Autowired 私有 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;
    }
  

  }

• JwtUtils类是：

  @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;
    }
  

  }

• AuthController类是：

  @CrossOrigin(origins = "*", maxAge = 3600) @RestController @RequestMapping("/api/auth") 公共类 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.";
        }
    }
  

文件application.properties，我放置：

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

在浏览器控制台中，我得到了该异常。

你能帮我解决这个问题吗？十分感谢。

Answer 1

你应该发表评论@PreAuthorize("hasRole('USER') or hasRole('MODERATOR') or hasRole('ADMIN')")。

说说结果？
