RedisConfig配置內容如下：

package com.example.demo5.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisClusterConfiguration;
import org.springframework.data.redis.connection.RedisNode;
 
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.stereotype.Component;
 
import redis.clients.jedis.JedisPoolConfig;
import java.util.HashSet;
import java.util.Set;

@Configuration
@Component
public class RedisConfig {
    @Value("${spring.redis.cluster.nodes}")
    private String nodes;

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

    @Value("${spring.redis.jedis.pool.min-idle}")
    
 
private int minIdle;

    @Value("${spring.redis.jedis.pool.max-active}")
    private int maxActive;

    @Value("${spring.redis.jedis.pool.max-wait}")
    private long maxWait;

    @Value("${spring.redis.jedis.pool.max-idle}")
    private int maxIdle;


    //redis配置
    public JedisPoolConfig poolConfig(){

        return jedisPoolConfig;
    }


    //redis叢集配置,6個ip以,分割，然後再以:分割
    public RedisClusterConfiguration redisClusterConfiguration(){
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
        String[] cNodes = nodes.split(",");
        Set<RedisNode> hp = new HashSet<>();
        for (String node : cNodes) {
            String[] split = node.split(":");
            hp.add(new RedisNode(split[0].trim(),Integer.valueOf(split[1])));
        }
        redisClusterConfiguration.setPassword(password);
        redisClusterConfiguration.setClusterNodes(hp);
        return redisClusterConfiguration;
    }

    //建立redis連線工廠
    public JedisConnectionFactory jedisConnectionFactory() {
        //叢集模式
        JedisConnectionFactory  factory = new JedisConnectionFactory(redisClusterConfiguration(),poolConfig());
        return factory;
    }


    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        initDomainRedisTemplate(redisTemplate);
        return redisTemplate;
    }

    //初始化redis序列化
    private void initDomainRedisTemplate(RedisTemplate<String, Object> redisTemplate) {
        //如果不配置Serializer，那麼儲存的時候預設使用String，如果用User型別儲存，那麼會提示錯誤User can't cast to String！
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //這個地方有一個問題，這種序列化器會將value序列化成物件儲存進redis中，如果
        //你想取出value，然後進行自增的話，這種序列化器是不可以的，因為物件不能自增；
        //需要改成StringRedisSerializer序列化器。
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        redisTemplate.setEnableTransactionSupport(true);
        redisTemplate.setConnectionFactory(jedisConnectionFactory());
    }

}
