我在一个基于Sping Boot 和Angular的Web应用程序上工作。当用户登录到客户端时,应用程序失败。我使用此链接https://github.com/bezkoder/angular-11-spring-boot-jwt-authentication作为教程参考。我得到以下错误:

Client-> Failed to load resource: the server responded with a status of 401 ()
Server -> AuthEntryPointJwt   : Unauthorized error: Full authentication is required to access this resource

身份验证入口点Jwt.java

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");
    }
}

验证令牌过滤器.java

public class AuthTokenFilter extends OncePerRequestFilter {
    @Autowired
    private JwtUtils jwtUtils;

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    private static final Logger logger = LoggerFactory.getLogger(AuthTokenFilter.class);
    public static final String TOKEN_PREFIX = "Bearer ";

    @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);

                if (!username.isEmpty()) {
                    UserDetails userDetails = userDetailsService.loadUserByUsername(username);
                    UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
                            userDetails, null, userDetails.getAuthorities());
                    authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));

                    SecurityContextHolder.getContext().setAuthentication(authentication);
                } else {
                    logger.error("Username is null");
                }
            }else {
                logger.error("jwt is null");
            }
        } 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(TOKEN_PREFIX)) {
            return headerAuth.substring(7, headerAuth.length());
        }

        return null;
    }
}

JwtUtils.java开发工具包

@Component
public class JwtUtils {
    private static final Logger logger = LoggerFactory.getLogger(JwtUtils.class);

    @Value("${jwtSecret}")
    private String jwtSecret;

    @Value("${jwtExpirationMs}")
    private String 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() + Integer.valueOf(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;
    }
}

Web安全配置.java

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    UserDetailsServiceImpl userDetailsService;

    public static final String[] AUTHENTICATED_URLS = { "/app/user/**", "/app/item/**"};
    public static final String SIGN_UP_URL = "/app/login" ;

    @Autowired
    private AuthEntryPointJwt unauthorizedHandler;

    @Bean
    public AuthTokenFilter authenticationJwtTokenFilter() {
        return new AuthTokenFilter();
    }

    @Bean
    public AuthEntryPointJwt authenticationEntryPointJwt() {
        return new AuthEntryPointJwt();
    }

    @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(SIGN_UP_URL).permitAll()
        .antMatchers(AUTHENTICATED_URLS ).permitAll()
        .anyRequest().authenticated();

        http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);   
    }

}

我在API端点上未启用安全性时看到过此错误。
您可以尝试将此属性添加到 application.properties 中,看看这样是否可以解决错误:

management.security.enabled=false
