java - 如何禁用特定网址的 Spring 安全性

Question

我正在使用无状态 Spring 安全，但在注册的情况下我想禁用 Spring 安全。我禁用了使用

antMatchers("/api/v1/signup").permitAll().

但它不起作用，我收到以下错误:

 message=An Authentication object was not found in the SecurityContext, type=org.springframework.security.authentication.AuthenticationCredentialsNotFoundException

我认为这意味着 spring 安全过滤器正在工作

我的 url 的顺序总是“/api/v1”

我的 Spring 配置是

@Override
    protected void configure(HttpSecurity http) throws Exception {

         http.
         csrf().disable().
         sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
         and().
         authorizeRequests().
         antMatchers("/api/v1/signup").permitAll().
         anyRequest().authenticated().
         and().
         anonymous().disable();
        http.addFilterBefore(new AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter.class);
    }

我的身份验证过滤器是

@Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = asHttp(request);
        HttpServletResponse httpResponse = asHttp(response);

        String username = httpRequest.getHeader("X-Auth-Username");
        String password = httpRequest.getHeader("X-Auth-Password");
        String token = httpRequest.getHeader("X-Auth-Token");

        String resourcePath = new UrlPathHelper().getPathWithinApplication(httpRequest);

        try {

            if (postToAuthenticate(httpRequest, resourcePath)) {            
                processUsernamePasswordAuthentication(httpResponse, username, password);
                return;
            }

            if(token != null){
                processTokenAuthentication(token);
            }
            chain.doFilter(request, response);
        } catch (InternalAuthenticationServiceException internalAuthenticationServiceException) {
            SecurityContextHolder.clearContext();
            logger.error("Internal authentication service exception", internalAuthenticationServiceException);
            httpResponse.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
        } catch (AuthenticationException authenticationException) {
            SecurityContextHolder.clearContext();
            httpResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED, authenticationException.getMessage());
        } finally {
        }
    }

     private HttpServletRequest asHttp(ServletRequest request) {
            return (HttpServletRequest) request;
        }

        private HttpServletResponse asHttp(ServletResponse response) {
            return (HttpServletResponse) response;
        }

        private boolean postToAuthenticate(HttpServletRequest httpRequest, String resourcePath) {
            return Constant.AUTHENTICATE_URL.equalsIgnoreCase(resourcePath) && httpRequest.getMethod().equals("POST");
        }

        private void processUsernamePasswordAuthentication(HttpServletResponse httpResponse,String username, String password) throws IOException {
            Authentication resultOfAuthentication = tryToAuthenticateWithUsernameAndPassword(username, password);
            SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
            httpResponse.setStatus(HttpServletResponse.SC_OK);
            httpResponse.addHeader("Content-Type", "application/json");
            httpResponse.addHeader("X-Auth-Token", resultOfAuthentication.getDetails().toString());
        }

        private Authentication tryToAuthenticateWithUsernameAndPassword(String username,String password) {
            UsernamePasswordAuthenticationToken requestAuthentication = new UsernamePasswordAuthenticationToken(username, password);
            return tryToAuthenticate(requestAuthentication);
        }

        private void processTokenAuthentication(String token) {
            Authentication resultOfAuthentication = tryToAuthenticateWithToken(token);
            SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
        }

        private Authentication tryToAuthenticateWithToken(String token) {
            PreAuthenticatedAuthenticationToken requestAuthentication = new PreAuthenticatedAuthenticationToken(token, null);
            return tryToAuthenticate(requestAuthentication);
        }

        private Authentication tryToAuthenticate(Authentication requestAuthentication) {
            Authentication responseAuthentication = authenticationManager.authenticate(requestAuthentication);
            if (responseAuthentication == null || !responseAuthentication.isAuthenticated()) {
                throw new InternalAuthenticationServiceException("Unable to authenticate Domain User for provided credentials");
            }
            logger.debug("User successfully authenticated");
            return responseAuthentication;
        }

我的 Controller 是

@RestController
public class UserController {

    @Autowired
    UserService userService;

    /**
     * to pass user info to service
     */
    @RequestMapping(value = "api/v1/signup",method = RequestMethod.POST)
    public String saveUser(@RequestBody User user) {
        userService.saveUser(user);
        return "User registerted successfully";
    }
}

我对spring完全陌生，请帮助我怎么做？

当使用 permitAll 时，它意味着每个经过身份验证的用户，但是您禁用了匿名访问，因此这将不起作用。

您想要的是忽略某些 URL，因为它会覆盖采用 WebSecurity 对象和 ignore 模式的 configure 方法。

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/api/v1/signup");
}

并从 HttpSecurity 部分中删除该行。这将告诉 Spring Security 忽略此 URL，并且不对它们应用任何过滤器。
