### **原因：** ###

CacheManager 没有找到，或者说没有生成

### **解决：** ###

**springboot 1.x  加上**

import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.cache.CacheManager;
    import org.springframework.cache.annotation.CachingConfigurerSupport;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.cache.RedisCacheManager;
    import org.springframework.data.redis.core.RedisTemplate;
    
    /**
     * RedisCacheConfig
     * 因为 这样配置是 1.x 的springboot 版本。
     * 
     */
    @Configuration
    @EnableCaching
    public class RedisCacheConfig  extends CachingConfigurerSupport {
    
        @Autowired
        protected RedisTemplate redisTemplate;
    
        //springcache集成redis做缓存
        @Override
        @Bean
        public CacheManager cacheManager() {
            RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
            //使用前缀
            redisCacheManager.setUsePrefix(true);
            return redisCacheManager;
        }
    
    }

**springboot 2.x  加上  略**
