Spring-data-redis @Cacheable java.lang.ClassCastException: java.util.HashMap ne peut pas être converti en java.lang.String

Question

Je veux utiliser spring-data-redis pour mettre en cache des données dans mon application de démarrage de printemps.Mais il Toujours dit cast exception.I googled pendant un certain temps, mais n'ont pas d'idées.Veuillez m'aider.thanks, toutes les suggestions sont greateful!

Voici mon RedisConfiguation:

@Configuration 
@EnableCaching 
public class RedisConfiguration extends CachingConfigurerSupport { 

@Value("${spring.redis.host}") 
private String host; 
@Value("${spring.redis.port}") 
private String port; 
@Value("${spring.redis.expire}") 
private String expire; 
@Value("${spring.redis.database}") 
private String databaseIndex; 
@Value("${spring.redis.password}") 
private String password; 

@Bean 
public KeyGenerator keyGenerator() { 
    return new KeyGenerator() { 
     public Object generate(Object target, Method method, Object... params) { 
      if (params.length == 0) { 
       return "reids_" + method.getName(); 
      } 
      if (params.length == 1) { 
       Object param = params[0]; 
       if (param != null && !param.getClass().isArray()) { 
        return "reids_" + method.getName() + "_" + param; 
       } 
      } 
      return "reids_" + method.getName() + " [" + StringUtils.arrayToCommaDelimitedString(params) + "]"; 
     } 
    }; 
} 

@Bean 
public CacheManager cacheManager(RedisTemplate redisTemplate) { 
    RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate); 
    redisCacheManager.setDefaultExpiration(Integer.parseInt(expire)); 
    redisTemplate.setHashValueSerializer(new StringRedisSerializer()); 
    redisTemplate.setKeySerializer(new StringRedisSerializer()); 
    redisTemplate.setValueSerializer(new StringRedisSerializer()); 
    redisTemplate.setHashKeySerializer(new StringRedisSerializer()); 
    return redisCacheManager; 
} 

@Bean(name = "redisTemplate") 
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) { 
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>(); 
    redisTemplate.setConnectionFactory(factory); 

    redisTemplate.setValueSerializer(new RedisSerializer<Object>() { 
     @Override 
     public byte[] serialize(Object object) throws SerializationException { 
      if (object == null) { 
       return new byte[0]; 
      } 
      if (!(object instanceof Serializable)) { 
       throw new IllegalArgumentException("RedisSerializer.serialize requires a Serializable payload " 
         + "but received an object of type [" + object.getClass().getName() + "]"); 
      } 
      return SerializationUtils.serialize((Serializable) object); 
     } 

     @Override 
     public Object deserialize(byte[] bytes) throws SerializationException { 
      if (bytes == null || bytes.length == 0) { 
       return null; 
      } 
      return SerializationUtils.deserialize(bytes); 
     } 
    }); 

    redisTemplate.afterPropertiesSet(); 
    return redisTemplate; 
} 

@Bean 
public JedisConnectionFactory redisConnectionFactory() { 
    JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory(); 
    // Defaults 
    redisConnectionFactory.setHostName(host); 
    redisConnectionFactory.setPort(Integer.parseInt(port)); 
    redisConnectionFactory.setDatabase(Integer.parseInt(databaseIndex)); 
    redisConnectionFactory.setPassword(password); 
    return redisConnectionFactory; 
} 
} 

et je l'utilise dans le contrôleur:

@Cacheable(value = "helloRedisCache",keyGenerator = "keyGenerator") 
@RequestMapping(value = "/Discovery/redisCache", method = RequestMethod.GET) 
public Map helloRedisCache() { 
    return new HashMap(); 
} 

et je me suis exception:

Answer 1

lors de l'enregistrement objet de hachage, Redis fonctionnera avec Jackson2JsonRedisSerializer qui peut être utilisé pour lier aux beans typés, ou insttype non typé ances.

redisTemplate.setHashValueSerializer(new Jackson2JsonRedisSerializer<>(Object.class)); 

Answer 2

Vous devez définir setObjectMapper

Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new 
Jackson2JsonRedisSerializer<Object>(Object.class); 
ObjectMapper om = new ObjectMapper(); 
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); 
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); 
jackson2JsonRedisSerializer.setObjectMapper(om);
