Springboot 实现Redis 同数据源动态切换db

public void setDataBase(int num) {
        LettuceConnectionFactory connectionFactory = (LettuceConnectionFactory) redisTemplate.getConnectionFactory();
        if (connectionFactory != null && num != connectionFactory.getDatabase()) {
            connectionFactory.setDatabase(num);
            this.redisTemplate.setConnectionFactory(connectionFactory);
            connectionFactory.resetConnection();
        }
    }
