Spring redisの操作

Spring redisの操作
Spring redisの基本操作には、stringオブジェクト、hashオブジェクト、listオブジェクト、key削除、レコードの追加が含まれます.

xml方式で注入されたredisTemplateに問題があるため@Autowired関連に問題があることを説明する理由を見てみましょう.

`No qualifying bean of type [org.springframework.data.redis.core.RedisTemplate] found for dependency`

つまりここに問題があるのです

 id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">  
        <property name="connectionFactory"   ref="connectionFactory" />  
       

主に以下のプラグインによるもので、バージョンが4.0になるとエラーになります
