问题描述 投票：2回答：1

当我尝试使用POSTMAN调用protected ws，并在登录后传递授权头和获得的token时，我得到了以下错误信息 Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJBZGVsSVAiLCJpYXQiOjE1NTI2MDM4NTIsImV4cCI6MTU1MjY5MDI1Mn0.OfzkQlhubdLBa9cV7O231M1AB8ya9g5Q1zefhjhPvJIICz45SUunT2xP6r008O-oxUXBQT3RrRha7n6gSo9Jpw.

请看下面我的实现。

1) Login api AuthRestAPIs.java。

@CrossOrigin(origins = "*", maxAge = 3600)
@RestController
@RequestMapping("/api/auth")
public class AuthRestAPIs {

    @Autowired
    AuthenticationManager authenticationManager;

    @Autowired
    private UserRepository userRepository;

    @Autowired
    RoleRepository roleRepository;

    @Autowired
    PasswordEncoder encoder;

    @Autowired
    JwtProvider jwtProvider;

    @PostMapping("/signin")
    public ResponseEntity<?> authenticateUser( @RequestBody LoginForm loginRequest) {

        Authentication authentication = authenticationManager.authenticate(
                new UsernamePasswordAuthenticationToken(
                        loginRequest.getUsername(),
                        loginRequest.getPassword()
                )
        );

        SecurityContextHolder.getContext().setAuthentication(authentication);
        String jwt = jwtProvider.generateJwtToken(authentication);
        return ResponseEntity.ok(new JwtResponse(jwt));
    }

}

测试api apiTestRestAPIs.java (protected resource):

@RestController
public class TestRestAPIs {

    @PreAuthorize("hasRole('ADMIN')")
    @GetMapping("/api/test//admin")
    public String adminAccess() {
        return ">>> Admin Contents";
    }
}

2) 安全配置类

@Configuration
@EnableWebSecurity
@ComponentScan(basePackages = "com.spring.jwtauthentication", scopedProxy = ScopedProxyMode.INTERFACES)
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("userDetailsServiceImpl")
    private UserDetailsService userDetailsService;

    @Autowired
    private JwtAuthEntryPoint unauthorizedHandler;


    public JwtAuthTokenFilter authenticationJwtTokenFilter() {
        JwtAuthTokenFilter test = new JwtAuthTokenFilter();
        return test;
    }

    @Autowired
    public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                .userDetailsService(this.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().
                authorizeRequests()
                .antMatchers("/api/auth/**").permitAll()
                .anyRequest().authenticated()
                .and()
                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
    }

}

3）JwtAuthTokenFilter.java。

@Component
public class JwtAuthTokenFilter extends OncePerRequestFilter {

    @Autowired
    private JwtProvider tokenProvider;

    @Autowired
    @Qualifier("userDetailsServiceImpl")
    private UserDetailsService userDetailsService;

    private static final Logger logger = LoggerFactory.getLogger(JwtAuthTokenFilter.class);

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain filterChain)
                                            throws ServletException, IOException {
        try {

            String jwt = getJwt(request);
            if (jwt!=null && tokenProvider.validateJwtToken(jwt)) {
                String username = tokenProvider.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("Can NOT set user authentication -> Message: {}", e);
        }

        filterChain.doFilter(request, response);
    }

    private String getJwt(HttpServletRequest request) {
        String authHeader = request.getHeader("Authorization");

        if (authHeader != null && authHeader.startsWith("Bearer ")) {
            return authHeader.replace("Bearer ","");
        }

        return null;
    }
}

4) JwtProvider.java。

@Component
public class JwtProvider {

    private static final Logger logger = LoggerFactory.getLogger(JwtProvider.class);


    private String jwtSecret = "jwtOlfaSecretKey";

    private int jwtExpiration =86400;

    public String generateJwtToken(Authentication authentication) {

        UserPrinciple userPrincipal = (UserPrinciple) authentication.getPrincipal();

        return Jwts.builder()
                        .setSubject((userPrincipal.getUsername()))
                        .setIssuedAt(new Date())
                        .setExpiration(new Date((new Date()).getTime() + jwtExpiration*1000))
                        .signWith(SignatureAlgorithm.HS512, jwtSecret)
                        .compact();
    }

    public boolean validateJwtToken(String authToken) {
        try {
            Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(authToken);
            return true;
        } catch (SignatureException e) {
            logger.error("Invalid JWT signature -> Message: {} ", e);
        } catch (MalformedJwtException e) {
            logger.error("Invalid JWT token -> Message: {}", e);
        } catch (ExpiredJwtException e) {
            logger.error("Expired JWT token -> Message: {}", e);
        } catch (UnsupportedJwtException e) {
            logger.error("Unsupported JWT token -> Message: {}", e);
        } catch (IllegalArgumentException e) {
            logger.error("JWT claims string is empty -> Message: {}", e);
        }

        return false;
    }

    public String getUserNameFromJwtToken(String token) {
        return Jwts.parser()
                            .setSigningKey(jwtSecret)
                            .parseClaimsJws(token)
                            .getBody().getSubject();
    }
}

5)JwtAuthEntryPoint.java。

@Component
public class JwtAuthEntryPoint implements AuthenticationEntryPoint {

    private static final Logger logger = LoggerFactory.getLogger(JwtAuthEntryPoint.class);

    @Override
    public void commence(HttpServletRequest request,
                         HttpServletResponse response,
                         AuthenticationException e) 
                                 throws IOException, ServletException {

        logger.error("Unauthorized error. Message - {}", e.getMessage());
        response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Error -> Unauthorized");
    }
}

使用@PreAuthorize("hasAuthority('ADMIN')")代替@PreAuthorize("hasRole('ADMIN')")，这样在你的情况下就可以了。
