在 Spring 引导 2 上配置 Jedis

Question

我正在尝试从 spring boot 1.5.5 迁移到 spring boot 2。我正在为 JedisPool

获取以下内容

Parameter 0 of method getJedisPool in com.company.spring.config.ApplicationConfig required a bean of type 'org.springframework.data.redis.connection.jedis.JedisConnectionFactory' that could not be found.
        - Bean method 'redisConnectionFactory' in 'JedisConnectionConfiguration' not loaded because @ConditionalOnMissingBean (types: org.springframework.data.redis.connection.RedisConnectionFactory; SearchStrategy: all) found beans of type 'org.springframework.data.redis.connection.RedisConnectionFactory' redisConnectionFactory

我正在尝试使用 Jedis 而不是 lettuce 进行配置。按照文档中的建议导入 spring-starter-redis-data 时，我忽略了 lettuce 模块。

下面是试图初始化 JedisPool 的代码。

@Bean
public JedisPool getJedisPool(JedisConnectionFactory jedisConnectionFactory) {
    String host = jedisConnectionFactory.getHostName();
    int port = jedisConnectionFactory.getPort();
    String password = StringUtils.isEmpty(jedisConnectionFactory.getPassword()) ? null : jedisConnectionFactory.getPassword();
    int timeout = jedisConnectionFactory.getTimeout();
    GenericObjectPoolConfig poolConfig = jedisConnectionFactory.getPoolConfig();
    log.info("Starting Redis with Host:{}, Port:{}, Timeout:{}, PoolConfig:{}", host, port, timeout, poolConfig);
    return new JedisPool(poolConfig, host, port, timeout, password);
}

我通过更改 bean 以使用 RedisProperties 解决了这个问题。这是最终运行的代码。

@Bean
public JedisPool getJedisPool(RedisProperties redisProperties) {
    Pool jedisProperties = redisProperties.getJedis().getPool();
    String password = StringUtils.isEmpty(redisProperties.getPassword()) ? null : redisProperties.getPassword();
    int timeout = (int) redisProperties.getTimeout().toMillis();
    GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
    poolConfig.setMaxIdle(jedisProperties.getMaxIdle());
    poolConfig.setMaxTotal(jedisProperties.getMaxActive() + jedisProperties.getMaxIdle());
    poolConfig.setMinIdle(jedisProperties.getMinIdle());
    log.info("Starting Redis with Host:{}, Port:{}, Timeout(ms):{}, PoolConfig:{}", redisProperties.getHost(), redisProperties.getPort(),
            timeout, poolConfig);
    return new JedisPool(poolConfig, redisProperties.getHost(), redisProperties.getPort(), timeout, password);
}

我不太确定这是否是在 SpringBoot 2.0 上配置 Jedis 的正确方法。无论如何，这是可行的。
