参考：https://stackoverflow.com/questions/43455869/could-not-autowire-there-is-more-than-one-bean-of-datasource-type

Parameter 0 of method redisTemplate in org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration required a single bean, but 6 were found:
    - agencyConnectionFactory: defined by method 'agencyConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]
    - cellConnectionFactory: defined by method 'cellConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]
    - mipConnectionFactory: defined by method 'mipConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]
    - wechatConnectionFactory: defined by method 'wechatConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]
    - ybtbConnectionFactory: defined by method 'ybtbConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]
    - ybtgConnectionFactory: defined by method 'ybtgConnectionFactory' in class path resource [com/sinosoft/config/RedisConfig.class]

除了这种还有配置数据库多数据源也会出现这种情况。

解决：

报错的某一个配置上加上@Primary
