Spring gateway + Oauth2实现单点登录及详细配置

 更新时间：2021年09月24日 16:55:06   作者：BBinChina  
gateway是基于 WebFlux的响应式编程框架，所以在使用securityConfig时采用的注解是@EnableWebFluxSecurity，接下来通过本文给大家介绍Spring gateway + Oauth2实现单点登录及详细配置，感兴趣的朋友一起看看吧

场景：

按职能，鉴权系统需要划分 网关（spring gateway） + 鉴权（auth-server）。本文通过实践搭建鉴权系统。

spring gateway

首先引入pom依赖

1、resilience 熔断器
2、gateway 网关
3、eureka client 服务注册中心
4、lombok插件
5、actuator状态监控

<dependencies>
 <!--        熔断器-->
        <dependency>
            <groupId>io.github.resilience4j</groupId>
            <artifactId>resilience4j-feign</artifactId>
            <version>1.1.0</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <!-- Gateway -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>

        <!-- 注册中心 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
</dependencies>

application.yml配置

1、gateway信息
2、actuator状态信息
3、配置eureka server地址及注册信息
4、日志配置
5、获取oauth2的jwt key

核心内容：security配置、PermissionFilter鉴权过滤器

1、security配置

package com.digquant.openapigateway.config;

import com.digquant.openapigateway.entity.Response;

import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.oauth2.jwt.ReactiveJwtDecoder;

import org.springframework.security.web.server.SecurityWebFilterChain;
import org.springframework.security.web.server.ServerAuthenticationEntryPoint;
import org.springframework.security.web.server.authorization.ServerAccessDeniedHandler;
import org.springframework.util.StringUtils;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;

import java.nio.charset.Charset;

@Slf4j
@Configuration
@AllArgsConstructor
@EnableWebFluxSecurity
public class SecurityConfig {

    private final ReactiveJwtDecoder jwtDecoder;

    @Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        http.cors().disable().csrf().disable();
        http
                .authorizeExchange()
                .pathMatchers("/**").permitAll()
                .pathMatchers("/**/public/**").permitAll()
                .pathMatchers("/**/static/**").permitAll()
                .pathMatchers("/*/oauth/**").permitAll()
                .pathMatchers("/actuator/**").permitAll()
                .pathMatchers(HttpMethod.OPTIONS).permitAll()
                .anyExchange().authenticated()
                .and()
                .exceptionHandling()
                .accessDeniedHandler(serverAccessDeniedHandler())
                .authenticationEntryPoint(serverAuthenticationEntryPoint())
                .and()
                .oauth2ResourceServer()
                .jwt()
                .jwtDecoder(jwtDecoder)
                .and()
                .bearerTokenConverter(new ServerBearerTokenAuthenticationConverter());
        return http.build();
    }

    @Bean
    public ServerAccessDeniedHandler serverAccessDeniedHandler() {
        return (exchange, denied) -> {
            log.debug("没有权限");
            String errMsg = StringUtils.hasText(denied.getMessage()) ? denied.getMessage() : "没有权限";
            Response result = new Response(1, errMsg);
            return create(exchange, result);
        };
    }

    @Bean
    public ServerAuthenticationEntryPoint serverAuthenticationEntryPoint() {
        return (exchange, e) -> {
            log.debug("认证失败");
            String errMsg = StringUtils.hasText(e.getMessage()) ? e.getMessage() : "认证失败";
            Response result = new Response(1, errMsg);
            return create(exchange, result);
        };
    }

    private Mono<Void> create(ServerWebExchange exchange, Response result) {
        return Mono.defer(() -> Mono.just(exchange.getResponse()))
                .flatMap(response -> {
                    response.getHeaders().setContentType(MediaType.APPLICATION_JSON_UTF8);
                    DataBufferFactory dataBufferFactory = response.bufferFactory();
                    DataBuffer buffer = dataBufferFactory.wrap(createErrorMsg(result));
                    return response.writeWith(Mono.just(buffer))
                            .doOnError(error -> DataBufferUtils.release(buffer));
                });
    }

    private byte[] createErrorMsg(Response result) {
        return result.getErrMsg().getBytes(Charset.defaultCharset());
    }
}

总结：

gateway是基于 WebFlux的响应式编程框架，所以在使用securityConfig时采用的注解是@EnableWebFluxSecurity

2、PermissionFilter

package com.digquant.openapigateway.filter;

import com.digquant.openapigateway.utils.IStrings;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.annotation.Order;
import org.springframework.http.HttpHeaders;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.security.core.context.ReactiveSecurityContextHolder;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.oauth2.jwt.Jwt;
import org.springframework.security.oauth2.server.resource.authentication.AbstractOAuth2TokenAuthenticationToken;
import org.springframework.security.oauth2.server.resource.authentication.JwtAuthenticationToken;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;

import java.util.Objects;

@Slf4j
@Order
@Component
@AllArgsConstructor
public class PermissionFilter implements WebFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        return ReactiveSecurityContextHolder.getContext()
                //排除没有Token的
                .filter(Objects::nonNull)
//                //检查该路径是否需要权限
//                .filter(var -> permissionStore.usingPermission(exchange.getRequest().getPath().value()))
                .map(SecurityContext::getAuthentication)
                .map(authentication -> (JwtAuthenticationToken) authentication)
                .doOnNext(jwtAuthenticationToken -> {
                    String path = exchange.getRequest().getPath().value();
                    log.info("请求 uri {}", path);
                })
                .map(AbstractOAuth2TokenAuthenticationToken::getPrincipal)
                .map(var -> (Jwt) var)
                .map(jwt -> {
                    String tokenValue = jwt.getTokenValue();
                    ServerHttpRequest.Builder builder = exchange.getRequest().mutate();
                    builder.header(HttpHeaders.AUTHORIZATION, IStrings.splice("Bearer ", tokenValue));
                    ServerHttpRequest request = builder.build();
                    return exchange.mutate().request(request).build();
                })
                .defaultIfEmpty(exchange)
                .flatMap(chain::filter);
    }
}

总结
1、使用permissionStore来记录uri的权限要求
2、获取到jwtToken时，处理token所携带的权限，用于匹配是否能请求对应资源

                .antMatchers("/oauth/**").permitAll()
                .antMatchers("/actuator/**").permitAll()
                .antMatchers("/").permitAll()
                .antMatchers(HttpMethod.OPTIONS).permitAll()
                .anyRequest().permitAll();
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.authenticationEntryPoint(authenticationEntryPoint)
                .accessDeniedHandler(accessDeniedHandler)
                .resourceId("auth-server");
    }
}

3、SecurityConfig配置

package com.digquant.config;

import com.digquant.service.CustomAuthenticationProvider;
import com.digquant.service.OAuthUserService;
import lombok.AllArgsConstructor;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Order(7)
@Configuration
@EnableWebSecurity
@AllArgsConstructor
@AutoConfigureAfter(ResourceServerConfig.class)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    private final OAuthUserService userService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable();
        http.authorizeRequests()
                .antMatchers("/oauth/**").permitAll()
                .antMatchers("/public/**").permitAll()
                .antMatchers("/actuator/**").permitAll()
                .antMatchers("/private/**").permitAll()
                .antMatchers("/").permitAll()
                .antMatchers(HttpMethod.OPTIONS).permitAll()
                .anyRequest().permitAll()
                .and()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/favor.ico");
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public AuthenticationProvider authenticationProvider() {
        CustomAuthenticationProvider provider = new CustomAuthenticationProvider()
                .setUserDetailsService(userService)
                .setPasswordEncoder(passwordEncoder());
        provider.setHideUserNotFoundExceptions(false);
        return provider;
    }

}

4、JwkController 用于gateway 请求jwt私钥

package com.digquant.controller;

import com.digquant.enity.JWTProperties;
import com.nimbusds.jose.jwk.JWKSet;
import com.nimbusds.jose.jwk.RSAKey;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.AllArgsConstructor;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;
import org.springframework.web.bind.annotation.*;

import java.security.interfaces.RSAPublicKey;
import java.util.Map;

@Api(tags = "jwk")
@RestController
@RequestMapping("/private")
@AllArgsConstructor
public class JwkController {
    private final KeyStoreKeyFactory keyStoreKeyFactory;

    private final JWTProperties jwtProperties;

    @ApiOperation("获取jwk")
    @PostMapping("/jwk_public_key")
    public Map<String, Object> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) keyStoreKeyFactory.getKeyPair(jwtProperties.getAuthJwtKey()).getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }

}

注意私钥放到项目的resources目录下

5、用户鉴权服务，获取用户信息

package com.digquant.service;

import com.digquant.enity.to.AuthenticationTO;
import com.digquant.enums.LoginType;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;
import org.springframework.util.CollectionUtils;

import java.util.List;
import java.util.Map;

@Slf4j
@Component
public class OAuthUserService implements UserDetailsService {

    @Autowired(required = false)
    private List<OAuthUserProcessor> oAuthUserProcessors;

    public UserDetails loadUser(String username, UsernamePasswordAuthenticationToken authentication) {
        AuthenticationTO authenticationTO = new AuthenticationTO();
        authenticationTO.setUsername(username);
        authenticationTO.setPassword((String) authentication.getCredentials());

        Map map = (Map) authentication.getDetails();
        String scope = (String) map.get("scope");
        String grantType = (String) map.get("grant_type");
        String clientId = (String) map.get("client_id");

        authenticationTO.setScope(scope);
        authenticationTO.setGrantType(grantType);
        authenticationTO.setLoginType(LoginType.PASSWORD);
        authenticationTO.setClientId(clientId);

        if (log.isDebugEnabled()) {
            log.debug("请求认证参数:{}", authenticationTO);
        }
        if (!CollectionUtils.isEmpty(oAuthUserProcessors)) {
            //目前只支持客户端密码登录方式
            for (OAuthUserProcessor oAuthUserProcessor : oAuthUserProcessors) {
                if (oAuthUserProcessor.support(authenticationTO)) {
                    UserDetails userDetails = oAuthUserProcessor.findUser(authenticationTO);
                    //TODO 需要加载OpenApi用户的权限
                    loadAuthorities(userDetails, authenticationTO);
                    return userDetails;
                }
            }
        }
        throw new UsernameNotFoundException("用户不存在");
    }

    private void loadAuthorities(UserDetails userDetails, AuthenticationTO authenticationTO) {

    }

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        return null;
    }
}

获取token
