springboot redis主从连法

在Spring Boot中使用Redis主从复制，需要在配置文件中指定主从节点的信息。具体步骤如下：

1. 在pom.xml文件中添加Redis和Lettuce的依赖：

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

<dependency>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
</dependency>

2. 在application.properties文件中配置Redis主从节点的信息：

# Redis主节点
spring.redis.host=192.168.0.1
spring.redis.port=6379

# Redis从节点
spring.redis.cluster.nodes=192.168.0.2:6379,192.168.0.3:6379

3. 在Redis配置类中创建RedisConnectionFactory对象，并设置主从节点信息：

@Configuration
public class RedisConfig {

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

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

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

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        RedisStandaloneConfiguration standaloneConfig = new RedisStandaloneConfiguration(host, port);
        RedisClusterConfiguration clusterConfig = new RedisClusterConfiguration(Arrays.asList(clusterNodes.split(",")));
        LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory(clusterConfig, standaloneConfig);
        return connectionFactory;
    }

}
