Spring gateway和Oauth2如何實(shí)現(xiàn)單點(diǎn)登錄

這篇文章主要介紹Spring gateway和Oauth2如何實(shí)現(xiàn)單點(diǎn)登錄，文中介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們一定要看完！

場(chǎng)景：

按職能，鑒權(quán)系統(tǒng)需要?jiǎng)澐?網(wǎng)關(guān)（spring gateway） + 鑒權(quán)（auth-server）。本文通過(guò)實(shí)踐搭建鑒權(quán)系統(tǒng)。

spring gateway

首先引入pom依賴(lài)

1、resilience 熔斷器
2、gateway 網(wǎng)關(guān)
3、eureka client 服務(wù)注冊(cè)中心
4、lombok插件
5、actuator狀態(tài)監(jiān)控

1、gateway信息
2、actuator狀態(tài)信息
3、配置eureka server地址及注冊(cè)信息
4、日志配置
5、獲取oauth3的jwt key

核心內(nèi)容：security配置、PermissionFilter鑒權(quán)過(guò)濾器

1、security配置

package com.digquant.openapigateway.config;

import com.digquant.openapigateway.entity.Response;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.buffer.DataBuffer;
import org.springframework.core.io.buffer.DataBufferFactory;
import org.springframework.core.io.buffer.DataBufferUtils;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.oauth3.jwt.ReactiveJwtDecoder;
import org.springframework.security.oauth3.server.resource.web.server.ServerBearerTokenAuthenticationConverter;
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()
                .oauth3ResourceServer()
                .jwt()
                .jwtDecoder(jwtDecoder)
                .and()
                .bearerTokenConverter(new ServerBearerTokenAuthenticationConverter());
        return http.build();
    }

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

    @Bean
    public ServerAuthenticationEntryPoint serverAuthenticationEntryPoint() {
        return (exchange, e) -> {
            log.debug("認(rèn)證失敗");
            String errMsg = StringUtils.hasText(e.getMessage()) ? e.getMessage() : "認(rèn)證失敗";
            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());
    }
}

總結(jié)：

gateway是基于 WebFlux的響應(yīng)式編程框架，所以在使用securityConfig時(shí)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.oauth3.jwt.Jwt;
import org.springframework.security.oauth3.server.resource.authentication.AbstractOAuth3TokenAuthenticationToken;
import org.springframework.security.oauth3.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()
                //排除沒(méi)有Token的
                .filter(Objects::nonNull)
//                //檢查該路徑是否需要權(quán)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("請(qǐng)求 uri {}", path);
                })
                .map(AbstractOAuth3TokenAuthenticationToken::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);
    }
}

總結(jié)
1、使用permissionStore來(lái)記錄uri的權(quán)限要求
2、獲取到j(luò)wtToken時(shí)，處理token所攜帶的權(quán)限，用于匹配是否能請(qǐng)求對(duì)應(yīng)資源

OAuth3 項(xiàng)目目錄

pom依賴(lài)

1、eureka client
2、spring boot mvc
3、redis 用于存儲(chǔ)jwt
4、mysql用于記錄用戶(hù)資源權(quán)限
5、oauth3組件
6、httpclient fregn用于用戶(hù)登陸鑒權(quán)

4、JwkController 用于gateway 請(qǐng)求jwt私鑰

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.oauth3.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("獲取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();
    }

}

注意私鑰放到項(xiàng)目的resources目錄下

5、用戶(hù)鑒權(quán)服務(wù)，獲取用戶(hù)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("請(qǐng)求認(rèn)證參數(shù):{}", authenticationTO);
        }
        if (!CollectionUtils.isEmpty(oAuthUserProcessors)) {
            //目前只支持客戶(hù)端密碼登錄方式
            for (OAuthUserProcessor oAuthUserProcessor : oAuthUserProcessors) {
                if (oAuthUserProcessor.support(authenticationTO)) {
                    UserDetails userDetails = oAuthUserProcessor.findUser(authenticationTO);
                    //TODO 需要加載OpenApi用戶(hù)的權(quán)限
                    loadAuthorities(userDetails, authenticationTO);
                    return userDetails;
                }
            }
        }
        throw new UsernameNotFoundException("用戶(hù)不存在");
    }

    private void loadAuthorities(UserDetails userDetails, AuthenticationTO authenticationTO) {

    }

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

獲取token

refresh_token
