Redis不支持集群错误——ERR This instance has cluster support disabled

缘起

最近手动配置了Redis的连接池

@Bean
public RedisTemplate<String, Object> redisTemplate() {
    RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
    redisClusterConfiguration.setClusterNodes(Arrays.asList(new RedisNode(redisHost,port)));
    redisClusterConfiguration.setPassword(password);
    LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisClusterConfiguration);
    RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
    redisStandaloneConfiguration.setHostName(redisHost);
    redisStandaloneConfiguration.setPort(port);
    redisStandaloneConfiguration.setPassword(password);
    LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisStandaloneConfiguration);
    lettuceConnectionFactory.setDatabase(db);
    lettuceConnectionFactory.afterPropertiesSet();
	RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(lettuceConnectionFactory);
    Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
    // 设置值（value）的序列化采用Jackson2JsonRedisSerializer。
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
    // 设置键（key）的序列化采用StringRedisSerializer。
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}

使用时报错：

修改RedisServer配置解决

提示语ERR This instance has cluster support disabled说明RedisServer不支持集群，网上很多文章都是修改Server配置重启解决此问题的，这不再赘述

修改RedisClient配置解决

我没公司RedisServer权限，公司的RedisServer不是集群部署，就是单个，那就只能从配置上修改一下了,Configuration从Cluster变成Standalone即可

@Bean
public RedisTemplate<String, Object> redisTemplate() {

   RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
   redisStandaloneConfiguration.setHostName(redisHost);
   redisStandaloneConfiguration.setPort(port);
   redisStandaloneConfiguration.setPassword(password);
   LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisStandaloneConfiguration);
   lettuceConnectionFactory.setDatabase(db);
   lettuceConnectionFactory.afterPropertiesSet();

   RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
   redisTemplate.setConnectionFactory(lettuceConnectionFactory);
   Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
   // 设置值（value）的序列化采用Jackson2JsonRedisSerializer。
   redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
   // 设置键（key）的序列化采用StringRedisSerializer。
   redisTemplate.setKeySerializer(new StringRedisSerializer());
   redisTemplate.setHashKeySerializer(new StringRedisSerializer());

   redisTemplate.afterPropertiesSet();
   return redisTemplate;
}
