springboot项目怎么实现多redis数据源？

在Spring Boot中，我们可以通过配置多个RedisConnectionFactory来实现多个Redis数据源。下面是具体实现步骤：

在application.properties或application.yml中配置多个Redis数据源的连接信息，如下所示：

# Redis数据源1
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=
spring.redis.database=0

# Redis数据源2
redis.datasource2.host=127.0.0.1
redis.datasource2.port=6380
redis.datasource2.password=
redis.datasource2.database=0

创建多个RedisConnectionFactory实例，分别对应不同的Redis数据源，如下所示：

@Configuration
public class RedisConfig {

    @Bean(name = "redis1ConnectionFactory")
    @ConfigurationProperties(prefix = "spring.redis")
    public RedisConnectionFactory redis1ConnectionFactory() {
        return new JedisConnectionFactory();
    }

    @Bean(name = "redis2ConnectionFactory")
    @ConfigurationProperties(prefix = "redis.datasource2")
    public RedisConnectionFactory redis2ConnectionFactory() {
        return new JedisConnectionFactory();
    }
}

创建多个RedisTemplate实例，分别对应不同的Redis数据源，如下所示：

@Configuration
public class RedisConfig {

    @Bean(name = "redis1Template")
    public RedisTemplate<String, Object> redis1Template(@Qualifier("redis1ConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }

    @Bean(name = "redis2Template")
    public RedisTemplate<String, Object> redis2Template(@Qualifier("redis2ConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }
}

在代码中使用对应的RedisTemplate访问不同的Redis数据源，如下所示：

@Autowired
@Qualifier("redis1Template")
private RedisTemplate<String, Object> redis1Template;

@Autowired
@Qualifier("redis2Template")
private RedisTemplate<String, Object> redis2Template;

public void test() {
    redis1Template.opsForValue().set("key1", "value1");
    redis2Template.opsForValue().set("key2", "value2");
}

以上就是在Spring Boot中实现多个Redis数据源的方式
