Spring-data-redis @Cacheable java.lang.ClassCastException: java.util.HashMap cannot be cast to java.lang.String

spring-data-redis

I want to use spring-data-redis to caching data in my spring boot app.But it always says cast exception.I googled for some time but have no ideas.Please help me.thanks,any suggestions are greateful!

Here is my 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;
}
}

And I use it in Controller:

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

And i got exception:

when storing hash object,redis will work with Jackson2JsonRedisSerializer which can be used to bind to typed beans, or untyped instances.

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

Change the serializer to the following

RedisSerializer<Object> serializer = new JdkSerializationRedisSerializer(getClass().getClassLoader());

redisTemplate.setDefaultSerializer(serializer);

In case you are using an object, ensure it is implementing Serializable.
