redis序列化设置，redis键、值...乱码

• 使用redis存值的时候发现值有乱码的情况，这是因为RedisTemplate可以接收任意Object作为值写入Redis，只不过写入前会把Object序列化为字节形式，默认是采用JDK序列化
• RedisTemplate提供了四种序列化方式
• 如果不指定序列化方式会默认采用JDK序列化
  
• 自定义序列化

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        // 序列化设置
        template.setKeySerializer(RedisSerializer.string());
        template.setValueSerializer(RedisSerializer.json());
        template.setHashKeySerializer(RedisSerializer.string());
        template.setHashValueSerializer(RedisSerializer.json());
        template.afterPropertiesSet();

        return template;
    }
}
