### 1.创建maven工程，导入依赖，pom文件内容如下 ###

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </plugin>
            </plugins>
        </build>
    </project>

## 2.在配置文件application.properties中添加redis集群配置 ##

# redis集群配置
    spring.redis.cluster.nodes=127.0.0.1:7000,127.0.0.1:7001,127.0.0.1:7002,127.0.0.1:7003,127.0.0.1:7004,127.0.0.1:7005
    # Redis服务器连接密码（默认为空）
    spring.redis.password=
    # 连接池最大连接数（使用负值表示没有限制）
    spring.redis.pool.max-active=20
    # 连接池最大阻塞等待时间（使用负值表示没有限制）
    spring.redis.pool.max-wait=-1
    # 连接池中的最大空闲连接
    spring.redis.pool.max-idle=20
    # 连接池中的最小空闲连接
    spring.redis.pool.min-idle=0
    # 连接超时时间（毫秒）
    spring.redis.timeout=60000

### 3.自定义配置类RedisClusterConfig.java ###

package com.szcatic.configuration;
    
    import java.util.HashSet;
    import java.util.Set;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import redis.clients.jedis.HostAndPort;
    import redis.clients.jedis.JedisCluster;
    import redis.clients.jedis.JedisPoolConfig;
    
    @Configuration
    public class RedisClusterConfig {
    	
    	@Value("${spring.redis.cluster.nodes}")
        private String clusterNodes;
    	
    	@Value("${spring.redis.database}")
        private int database;
    
        @Value("${spring.redis.timeout}")
        private int timeout;
    
        @Value("${spring.redis.pool.max-idle}")
        private int maxIdle;
    
        @Value("${spring.redis.pool.min-idle}")
        private int minIdle;
    
        @Value("${spring.redis.pool.max-active}")
        private int maxActive;
    
        @Value("${spring.redis.pool.max-wait}")
        private long maxWait;
    
    	@Bean
    	public JedisCluster getJedisCluster() {
    		return new JedisCluster(getNodes(), timeout, poolConfig());
    	}
    	
    	private JedisPoolConfig poolConfig() {
    		JedisPoolConfig config = new JedisPoolConfig(); 
            config.setMaxIdle(maxIdle);
            config.setMinIdle(minIdle);
            config.setMaxTotal(maxActive);
            config.setMaxWaitMillis(maxWait);
            return config;
    	}
    	
    	private Set<HostAndPort> getNodes() {
    		String[] cNodes = clusterNodes.split(",");
    		Set<HostAndPort> nodes = new HashSet<HostAndPort>();
    		// 分割出集群节点
    		String[] hp;
    		for (String node : cNodes) {
    			hp = node.split(":");
    			nodes.add(new HostAndPort(hp[0], Integer.parseInt(hp[1])));
    		}
    		return nodes;
    	}
    }

### 4.编写测试类RedisClusterConfigTest.java ###

package com.szcatic.test;
    
    import org.junit.jupiter.api.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    
    import redis.clients.jedis.JedisCluster;
    
    public class RedisClusterConfigTest {
    	
    	@Autowired
    	private JedisCluster jedisCluster;
    	
    	@Test
    	void test() {
    		jedisCluster.set("userName", "zhangsan");
    		String userName = jedisCluster.get("userName");
    		System.out.println("userName======" + userName);
    	}
    }

### 5.启动redis集群，运行测试方法test()，控制台输出内容如下 ###
