Redis key 乱码问题（springboot）

• 保存到redis中的key 前半段会出现乱码问题

  

• 原来配置：

  @Configuration
  @EnableCaching
  public class RedisCacheConfig {
      @Bean
      public CacheManager cacheManager(RedisTemplate<?, ?> redisTemplate) {
      CacheManager cacheManager = new RedisCacheManager(redisTemplate);
      return cacheManager;
      }
   
      @SuppressWarnings("rawtypes")
      @Bean
      public RedisTemplate redisTemplate(RedisConnectionFactory factory){
      RedisTemplate redisTemplate = new RedisTemplate();
          RedisSerializer stringSerializer = new StringRedisSerializer();
          redisTemplate.setConnectionFactory(factory);
          return redisTemplate;
      }
  }

• 到 redisTemplate方法中添加如下代码段

  @SuppressWarnings("rawtypes")
  @Bean
  public RedisTemplate redisTemplate(RedisConnectionFactory factory){
  RedisTemplate redisTemplate = new RedisTemplate();
      RedisSerializer stringSerializer = new StringRedisSerializer();
      redisTemplate.setConnectionFactory(factory);
      redisTemplate.setKeySerializer(stringSerializer);
      redisTemplate.setValueSerializer(stringSerializer);
      redisTemplate.setHashKeySerializer(stringSerializer);
      redisTemplate.setHashValueSerializer(stringSerializer);
      return redisTemplate;
  }

• 修改后key值显示正常
