spring redis 主从集群配置

以下是Spring Boot集成Redis主从集群的配置方法：

1.在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.在application.properties文件中添加以下配置：

# Redis主节点配置
spring.redis.master.host=127.0.0.1
spring.redis.master.port=6379
spring.redis.master.password=123456

# Redis从节点配置
spring.redis.slave.nodes=127.0.0.1:6380,127.0.0.1:6381
spring.redis.slave.password=123456

3.创建RedisConfig类，配置RedisTemplate和JedisConnectionFactory：

@Configuration
public class RedisConfig {

    @Value("${spring.redis.master.host}")
    private String masterHost;

    @Value("${spring.redis.master.port}")
    private int masterPort;

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

    @Value("${spring.redis.slave.nodes}")
    private String slaveNodes;

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

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

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration()
                .master("mymaster")
                .sentinel("127.0.0.1", 26379)
                .sentinel("127.0.0.1", 26380)
                .sentinel("127.0.0.1", 26381)
                .setPassword(masterPassword);
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(sentinelConfig);
        jedisConnectionFactory.setUsePool(true);
        jedisConnectionFactory.setPoolConfig(jedisPoolConfig());
        return jedisConnectionFactory;
    }

    @Bean
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(100);
        jedisPoolConfig.setMaxIdle(50);
        jedisPoolConfig.setMinIdle(20);
        jedisPoolConfig.setMaxWaitMillis(3000);
        return jedisPoolConfig;
    }
}

4.在需要使用Redis的类中注入RedisTemplate即可使用。
