Question

我有一个使用SpringBoot，Jersey2和Keycloak构建的API。我使用的是SpringBoot适配器以及SpringAdapter。一切都很好。

我现在偶然发现了这个页面https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-2.X-Project-Setup-1.5

并开始使用swagger-core包为我的API生成swagger.json文件。 swagger-jersey2依赖项会在swagger.json这样的链接中公开http://localhost:8080/swagger.json文件：SecurityConfig。但是，我无法公开访问该网址，因为密钥泄露会阻止它。

在我的public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter { //....other code above @Override protected void configure(HttpSecurity http) throws Exception { super.configure(http); http.csrf().disable().authorizeRequests().antMatchers("*").permitAll(); http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS); } }课程中，我有以下内容：

swagger.json

如何更改配置以允许访问Interface而无需传递承载令牌？（我测试了使用不记名令牌进行访问，但它工作正常，但我需要在没有持票人令牌的情况下访问它）

Answer 1

我最后通过以下方式解决了这个问题：

创建新的PubliResource注释。
在启动时使用PublicResource注释的类创建了一个列表，然后显式地让请求投放在这些类上，即使没有检测到令牌。

import java.lang.annotation.*;

/***
 * Used for marking a class accessible to a non-authorized user for
 * @GET, @PUT, @POST, and @DELETE annotations
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@Inherited
public @interface PublicResource {

}

然后我做了一个AuthenticationTokenProcessingFilter bean。

import org.keycloak.KeycloakSecurityContext;
import org.keycloak.adapters.AdapterUtils;
import org.keycloak.adapters.RefreshableKeycloakSecurityContext;
import org.keycloak.representations.AccessToken;
import org.reflections.Reflections;
import org.reflections.util.ConfigurationBuilder;
import org.springframework.web.filter.GenericFilterBean;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.*;
import java.io.IOException;
import java.lang.reflect.Method;
import java.util.Set;
import java.util.TreeSet;

public class AuthenticationTokenProcessingFilter extends GenericFilterBean {

    private static Set<String> nonAuthenticationWhiteListSet = new TreeSet<>();

    static {
        ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
        configurationBuilder.forPackages("com.package.code.resources"); //IMPORTANT
        Reflections reflections = new Reflections(configurationBuilder);
        Set<Class<?>> annotated = reflections.getTypesAnnotatedWith(PublicResource.class);
        for (Class<?> annotatedClass : annotated) {
            if (!annotatedClass.isAnnotationPresent(Path.class)) {
                continue;
            }
            String classPath = annotatedClass.getAnnotation(Path.class).value();

            for (Method method : annotatedClass.getDeclaredMethods()) {
                String fullPath = classPath;
                if (method.isAnnotationPresent(GET.class)
                        || method.isAnnotationPresent(POST.class)
                        || method.isAnnotationPresent(PUT.class)
                        || method.isAnnotationPresent(DELETE.class)) {
                    if (method.isAnnotationPresent(Path.class)) {
                        fullPath += method.getDeclaredAnnotation(Path.class).value();
                    }

                    fullPath = fullPath.replaceAll("\\{.*\\}", "[^/]+");
                    nonAuthenticationWhiteListSet.add(fullPath);
                }
            }
        }
    }

    public AuthenticationTokenProcessingFilter() {}

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        if (!(request instanceof HttpServletRequest)) {
            throw new RuntimeException("Expecting a HTTP request");
        }

        RefreshableKeycloakSecurityContext context = (RefreshableKeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());

        if (context == null) {
            handleNoSecurityContext(request, response, chain);
            return;
        }

        chain.doFilter(request, response);
    }

    private void handleNoSecurityContext(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest httpRequest = (HttpServletRequest) request;
        String path = httpRequest.getPathInfo();

        if (isPublicResource(path)) {
            chain.doFilter(request, response);
            return;
        }

        ((HttpServletResponse) response).setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        return;
    }

    private boolean isPublicResource(String path) {
        for (String regex : nonAuthenticationWhiteListSet) {
            if (path.matches(regex)) {
                return true;
            }
        }

        return false;
    }
}

然后在我的主要课程中我做了这个，所以它会被注册为过滤器。

@Configuration
@EnableAutoConfiguration(exclude = {FallbackWebSecurityAutoConfiguration.class, SpringBootWebSecurityConfiguration.class, DataSourceAutoConfiguration.class})
@ComponentScan
@EnableAsync
public class MyApi {

    //...other code plus the main method

    @Bean
    public AuthenticationTokenProcessingFilter authFilter() {
        return new AuthenticationTokenProcessingFilter();
    }
}

Keycloak保护API试图公开swagger.json
