怎么使用Spring Data Redis实现Spring Authorization Server的核心services？

本文对应的是文档中的How-to: Implement core services with JPA，文档中使用Jpa实现了核心的三个服务类：授权信息、客户端信息和授权确认的服务；本文会使用Spring Data Redis参考文档来添加新的实现。在这里也放一下文档中的一句话： 本指南的目的是为您自己实现这些服务提供一个起点，以便您可以根据自己的需要进行修改。

修改RedisConfig类 重要

添加注解@EnableRedisRepositories(enableKeyspaceEvents = RedisKeyValueAdapter.EnableKeyspaceEvents.ON_STARTUP)，在启动后添加Redis数据失效时间，自动删除@Indexed注解生成的索引(Secondary Indexes)。

package com.example.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisKeyValueAdapter;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.repository.configuration.EnableRedisRepositories;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import org.springframework.security.jackson2.CoreJackson2Module;

/**
 * Redis的key序列化配置类
 *
 * @author vains
 */
@Configuration
@RequiredArgsConstructor
@EnableRedisRepositories(enableKeyspaceEvents = RedisKeyValueAdapter.EnableKeyspaceEvents.ON_STARTUP)
public class RedisConfig {

    private final Jackson2ObjectMapperBuilder builder;

    /**
     * 默认情况下使用
     *
     * @param connectionFactory redis链接工厂
     * @return RedisTemplate
     */
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        // 字符串序列化器
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // 创建ObjectMapper并添加默认配置
        ObjectMapper objectMapper = builder.createXmlMapper(false).build();

        // 序列化所有字段
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);

        // 此项必须配置，否则如果序列化的对象里边还有对象，会报如下错误：
        //     java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to XXX
        objectMapper.activateDefaultTyping(
                objectMapper.getPolymorphicTypeValidator(),
                ObjectMapper.DefaultTyping.NON_FINAL,
                JsonTypeInfo.As.PROPERTY);

        // 添加Security提供的Jackson Mixin
        objectMapper.registerModule(new CoreJackson2Module());

        // 存入redis时序列化值的序列化器
        Jackson2JsonRedisSerializer<Object> valueSerializer =
                new Jackson2JsonRedisSerializer<>(objectMapper, Object.class);

        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();

        // 设置值序列化
        redisTemplate.setValueSerializer(valueSerializer);
        // 设置hash格式数据值的序列化器
        redisTemplate.setHashValueSerializer(valueSerializer);
        // 默认的Key序列化器为：JdkSerializationRedisSerializer
        redisTemplate.setKeySerializer(stringRedisSerializer);
        // 设置字符串序列化器
        redisTemplate.setStringSerializer(stringRedisSerializer);
        // 设置hash结构的key的序列化器
        redisTemplate.setHashKeySerializer(stringRedisSerializer);

        // 设置连接工厂
        redisTemplate.setConnectionFactory(connectionFactory);

        return redisTemplate;
    }

实现步骤

因为本文使用的是Spring Data，所以需要先定义对应的实体，然后根据实体定义对应的Repository(Spring Data Repository)，最后实现核心的service，使用这些Repository操作Redis。

  1. 定义实体
  2. 定义Redis Repositories
  3. 实现核心服务类

具体实现

定义实体

标题中的类是框架中对应的默认实体，下方代码中的类都是从标题后边的类中映射数据从而保存至Redis。

客户端实体(RegisteredClient)

package com.example.entity.security;

import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.redis.core.RedisHash;
import org.springframework.data.redis.core.index.Indexed;

import java.io.Serializable;
import java.time.Instant;

/**
 * 基于redis存储的客户端实体
 *
 * @author vains
 */
@Data
@RedisHash(value = "client")
public class RedisRegisteredClient implements Serializable {

    /**
     * 主键
     */
    @Id
    private String id;

    /**
     * 客户端id
     */
    @Indexed
    private String clientId;

    /**
     * 客户端id签发时间
     */
    private Instant clientIdIssuedAt;

    /**
     * 客户端秘钥
     */
    private String clientSecret;

    /**
     * 客户端秘钥过期时间
     */
    private Instant clientSecretExpiresAt;

    /**
     * 客户端名称
     */
    private String clientName;

    /**
     * 客户端支持的认证方式
     */
    private String clientAuthenticationMethods;

    /**
     * 客户端支持的授权申请方式
     */
    private String authorizationGrantTypes;

    /**
     * 回调地址
     */
    private String redirectUris;

    /**
     * 登出回调地址
     */
    private String postLogoutRedirectUris;

    /**
     * 客户端拥有的scope
     */
    private String scopes;

    /**
     * 客户端配置
     */
    private String clientSettings;

    /**
     * 通过该客户端签发的access token设置
     */
    private String tokenSettings;

注解解释

  1. @RedisHash标注这是一个Spring Data Redis的实体类，同时也指定了该类保存在Redis时的key前缀。
  2. @Id指定id属性，id属性也会被当做key的一部分，本注解和上个这两个注解项负责创建用于持久化哈希的实际键。
  3. @Indexed注解标注的字段会创建一个基于该字段的索引，让Repository支持findBy被注解标注的字段名等方法。
  4. @TimeToLive注解标注的字段会被用来当做该对象在Redis的过期时间，虽然RedisHash也支持设置过期时间，但是不够灵活，所以额外添加一个字段针对某条数据设置过期时间。

定义Spring Data Repositories(Redis Repositories)

Spring Data Repository是Spring Data抽象出来的一个增删改查的interface接口，适用于Spring Data的不同实现，框架提供了支持增删改查的公共Repository： CrudRepository<实体类，主键类型>。

客户端Repository

像下边的接口中有一个findByClientId方法，但是ClientId属性并不是主键，如果不加@Indexed注解，则该方法就不会生效。

package com.example.repository;

import com.example.entity.security.RedisRegisteredClient;
import org.springframework.data.repository.CrudRepository;

import java.util.Optional;

/**
 * 基于Spring Data Redis的客户端repository
 *
 * @author vains
 */
public interface RedisClientRepository extends CrudRepository<RedisRegisteredClient, String> {

    /**
     * 根据客户端Id查询客户端信息
     *
     * @param clientId 客户端id
     * @return 客户端信息
     */
    Optional<RedisRegisteredClient> findByClientId(String clientId);

授权信息Repository

提供根据state, authorizationCodeValue, accessTokenValue, refreshTokenValue, userCodeValue 和 deviceCodeValue属性查询的方法，在service中组合使用。

package com.example.repository;

import com.example.entity.security.RedisOAuth2Authorization;
import org.springframework.data.repository.CrudRepository;

import java.util.Optional;

/**
 * oauth2授权管理
 *
 * @author vains
 */
public interface RedisOAuth2AuthorizationRepository extends CrudRepository<RedisOAuth2Authorization, String> {

    /**
     * 根据授权码获取认证信息
     *
     * @param token 授权码
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByAuthorizationCodeValue(String token);

    /**
     * 根据access token获取认证信息
     *
     * @param token access token
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByAccessTokenValue(String token);

    /**
     * 根据刷新token获取认证信息
     *
     * @param token 刷新token
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByRefreshTokenValue(String token);

    /**
     * 根据id token获取认证信息
     *
     * @param token id token
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByOidcIdTokenValue(String token);

    /**
     * 根据用户码获取认证信息
     *
     * @param token 用户码
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByUserCodeValue(String token);

    /**
     * 根据设备码获取认证信息
     *
     * @param token 设备码
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByDeviceCodeValue(String token);

    /**
     * 根据state获取认证信息
     *
     * @param token 授权申请时的state
     * @return 认证信息
     */
    Optional<RedisOAuth2Authorization> findByState(String token);

授权确认信息Repository

提供一个根据客户端Id和授权确认用户的username查询的方法。

package com.example.repository;

import com.example.entity.security.RedisAuthorizationConsent;
import org.springframework.data.repository.CrudRepository;

import java.util.Optional;

/**
 * 基于redis的授权确认repository
 *
 * @author vains
 */
public interface RedisAuthorizationConsentRepository extends CrudRepository<RedisAuthorizationConsent, String> {

    /**
     * 根据客户端id和授权确认用户的 username 查询授权确认信息
     *
     * @param registeredClientId 客户端id
     * @param principalName      授权确认用户的 username
     * @return 授权确认记录
     */
    Optional<RedisAuthorizationConsent> findByRegisteredClientIdAndPrincipalName(String registeredClientId, String principalName);

}

以下内容摘抄自文档内容

查询方法允许从方法名自动派生简单的查找器查询，请确保在查找器方法中使用的属性已设置为索引。

下表提供了Redis支持的关键字概述，以及包含该关键字的方法本质上是什么:

写在最后

    到此为止基本就结束了，本文章和前边的所有系列文章没有必要的关联，如果是第一次看到文章的读者也是可以很顺畅的将文章中的内容引入项目，当然，因为引用了Spring Data Redis，所以项目必须要先有Redis支持。

文章看起来很长，但是实际上就是定义三个实体类，定义三个Repository，然后实现核心的service；逻辑并不复杂，操作Redis的内容因为使用了Spring Data Repositories，所以这两部分内容很少，内容多得地方就在每个service中实体与默认实体的转换中，一大堆的转换内容导致文章看起来内容很多，但是这些内容在文档中都已经实现，所以说这部分内容直接Copy就行，哈哈。
