项目配置文件：

spring:
  redis:
    database: 0
    host-name: localhost
    port: 6379
  redis1:
    database: 1
    host-name: localhost
    port: 6379

多数据源配置文件：

import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.StringRedisTemplate;

    }

    /**

    @Primary
    @Bean("factory")
    public LettuceConnectionFactory factory(@Qualifier("redisConfig") RedisStandaloneConfiguration redisConfig) {

    @Bean("factory1")
    public LettuceConnectionFactory factory1(@Qualifier("redisConfig1")RedisStandaloneConfiguration redisConfig1) {

    }

    @Primary
    @Bean("stringRedisTemplate")
    public StringRedisTemplate stringRedisTemplate(@Qualifier("factory") LettuceConnectionFactory factory) {
        StringRedisTemplate temple = new StringRedisTemplate();
        temple.setConnectionFactory(factory);

    @Test
    void operateDb() {
        stringRedisTemplate.opsForValue().set("test0", "test", 1, TimeUnit.SECONDS);
    }

    @Autowired
