springsecurity oauth2.0 客户端动态跳过认证

您好，关于在 Spring Security OAuth2.0 客户端动态跳过认证，可以使用自定义过滤器来实现，具体实现如下：

1.自定义过滤器：

public class SkipTokenFilter extends OncePerRequestFilter {

  private AntPathMatcher antPathMatcher = new AntPathMatcher();

  @Autowired
  private OAuth2AuthorizedClientService authorizedClientService;

  @Autowired
  private OAuth2AuthorizedClientRepository authorizedClientRepository;

  @Override
  protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
    String requestURI = request.getRequestURI();
    String clientRegistrationId = "your-client-registration-id"; // 客户端注册ID
    if (!antPathMatcher.match("/oauth2/**", requestURI) && !antPathMatcher.match("/error", requestURI)) {
      OAuth2AuthorizedClient authorizedClient = authorizedClientService.loadAuthorizedClient(clientRegistrationId, getAuthentication(request), request);
      if (authorizedClient == null) {
        // 跳过认证
        HttpSession session = request.getSession(false);
        if (session != null) {
          session.setAttribute(OAuth2AuthorizationContext.class.getName(), new OAuth2AuthorizationContext(null, null, clientRegistrationId));
        }
        filterChain.doFilter(request, response);
        return;
      }
      request.setAttribute(OAuth2AuthorizationContext.class.getName(), new OAuth2AuthorizationContext(authorizedClient.getAccessToken(), null, clientRegistrationId));
    }
    filterChain.doFilter(request, response);
  }

  private Authentication getAuthentication(HttpServletRequest request) {
    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
    if (authentication == null) {
      String authorization = request.getHeader(HttpHeaders.AUTHORIZATION);
      if (StringUtils.isNotEmpty(authorization)) {
        int index = authorization.indexOf(' ');
        if (index > 0) {
          String type = authorization.substring(0, index);
          if ("Bearer".equalsIgnoreCase(type)) {
            String token = authorization.substring(index + 1);
            authentication = new BearerTokenAuthentication(new BearerTokenAuthenticationToken(token));
          }
        }
      }
    }
    return authentication;
  }
}

2.在 Spring Security 配置中添加自定义过滤器：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    // ...
    http.addFilterBefore(new SkipTokenFilter(), OAuth2AuthorizationRequestRedirectFilter.class);
  }
}

以上就是通过自定义过滤器在 Spring Security OAuth2.0 客户端动态跳过认证的实现方法，希望能对您有所帮助。
