Redis可以很容易地集成到Sping Boot 中，而不依赖Spring Data Redis。
使用依赖关系：

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>

在应用程序中创建一个RedisClient/Helper bean

@Component
@Slf4j
public class RedisClient {

    private JedisPool pool;

    @PostConstruct
    public void initialize() {
        try {
            JedisPoolConfig poolConfig = new JedisPoolConfig();
            poolConfig.setMinIdle(ApplicationConstant.REDIS_MIN_IDLE);
            poolConfig.setMaxTotal(ApplicationConstant.REDIS_MAX_TOTAL);
            poolConfig.setMaxIdle(ApplicationConstant.REDIS_MAX_IDLE);
            URI uri = URI.create(ApplicationConstant.REDIS_SERVER_URL);
            pool = new JedisPool(poolConfig, uri);
            try (Jedis client = pool.getResource()){
                if (client.isBroken()) throw new JedisConnectionException("Unable to create Jedis pool please check the configurations.");
            }
            log.info("Redis connection established.");
        } catch (JedisConnectionException e) {
            log.error("Error in creating jedis pool", e);
            throw e;
        }
    }

    @PreDestroy
    public void close() {
        if (pool!=null && !pool.isClosed()) {
            pool.close();
        }
    }

    public String get(String key) {
        try(Jedis jedis = pool.getResource()) {
            return jedis.get(key);
        } 
    }

    public String set(String key, String value) {
        try(Jedis jedis = pool.getResource()) {
            return jedis.set(key, value);
        }
    }
}

现在，只需在您想要的任何地方自动连接/注入bean。

@Repository
public class MyDao{

    @Autowired
    private EntityManager em;
    @Autowired
    private RedisClient redisClient;

    public String getData(String key) {
        String obj = redisClient.get(key);
        if (obj != null) {
           return obj;
        }
        String result= em.find(String.class, key);
        redisClient.set(key, result);
        return resp;
    }
}
