连接腾讯云redis集群 Redis配置类RedisConfig.java 示例代码

以下是连接腾讯云 Redis 集群的配置类 RedisConfig.java 示例代码：

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisClusterConfiguration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;

@Configuration
public class RedisConfig {

    @Value("${spring.redis.cluster.nodes}")
    private String clusterNodes;

    @Value("${spring.redis.password}")
    private String password;

    @Value("${spring.redis.timeout}")
    private int timeout;

    @Bean
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(20);
        jedisPoolConfig.setMaxIdle(10);
        jedisPoolConfig.setMinIdle(5);
        jedisPoolConfig.setMaxWaitMillis(10000);
        jedisPoolConfig.setTestOnBorrow(true);
        jedisPoolConfig.setTestOnReturn(true);
        jedisPoolConfig.setTestWhileIdle(true);
        return jedisPoolConfig;
    }

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
        redisClusterConfiguration.setClusterNodes(getClusterNodes());
        redisClusterConfiguration.setMaxRedirects(3);
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisClusterConfiguration, jedisPoolConfig());
        jedisConnectionFactory.setPassword(getPassword());
        jedisConnectionFactory.setTimeout(getTimeout());
        return jedisConnectionFactory;
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    private String getClusterNodes() {
        return clusterNodes;
    }

    private String getPassword() {
        return password;
    }

    private int getTimeout() {
        return timeout;
    }
}

需要在 application.properties 或 application.yml 中添加以下配置：

spring:
  redis:
    cluster:
      nodes: <redis集群节点>
    password: <密码>
    timeout: <连接超时时间>

其中 `<redis集群节点>` 是 Redis 集群的节点地址，多个节点之间用逗号隔开，例如 `redis-1:6379,redis-2:6379`。`<密码>` 是 Redis 集群的密码，如果没有密码可以不填写。`<连接超时时间>` 是连接 Redis 集群的超时时间，单位为毫秒。
