1. redis类似乱码问题，可修redisTemplate 的配置，配置如下

   @Configuration
   @EnableCaching
   @EnableAutoConfiguration
   public class RedisConfiguration extends CachingConfigurerSupport {
       /**
        * 自定义生成key的规则
        */
       @Override
       public KeyGenerator keyGenerator() {
           return new KeyGenerator() {
               @Override
               public Object generate(Object o, Method method, Object... objects) {
                   //格式化缓存key字符串
                   StringBuilder sb = new StringBuilder();
                   //追加类名
                   sb.append(o.getClass().getName());
                   //追加方法名
                   sb.append(method.getName());
                   //遍历参数并且追加
                   for (Object obj : objects) {
                       sb.append(obj.toString());
                   }
                   System.out.println("调用Redis缓存Key : " + sb.toString());
                   return sb.toString();
               }
           };
       }
   
       /**
        * 采用RedisCacheManager作为缓存管理器
        * @param connectionFactory
        */
       @Bean
       public CacheManager cacheManager(RedisConnectionFactory connectionFactory) {
           RedisCacheManager redisCacheManager = RedisCacheManager.create(connectionFactory);
           return  redisCacheManager;
       }
   
       @Bean
       public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
           StringRedisTemplate redisTemplate = new StringRedisTemplate(factory);
           Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
           ObjectMapper om = new ObjectMapper();
           om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
           om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
           jackson2JsonRedisSerializer.setObjectMapper(om);
           //设置完这个可以直接将对象以json格式存入redis中，但是取出来的时候要用JSON.parseArray(Json.toJsonString(object),Object.class)解析一下
           redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
           redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
           //调用后完成设置
           redisTemplate.afterPropertiesSet();
           return redisTemplate;
       }
   
   
   }

   遇到的问题：原先在springboot启动类中添加叻@ComponentScan并且没有扫描@Configuration中的类，导致redisTemplate配置失败，添加扫描路径即可。
