使用spring向redis中存資料時，發現key出現了很不友好的字元，例如：
解決辦法：
手動定義序列化的方法，spring-data-redis中還提供了一個序列化的類專門針對string型別的序列化org.springframework.data.redis.serializer.StringRedisSerializer這個類,我們在帶有@Configuration註解的類中覆蓋自動配置的RedisTemplate<Object,Object>，如下：

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@SpringBootConfiguration
public class RedisConfig {

    @Bean
    public RedisTemplate<Object,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<Object,Object> redisTemplate = new RedisTemplate<>();
        // 設定redis連線
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        // 使用Jackson2JsonRedisSerialize 替換預設序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 設定value的序列化規則和 key的序列化規則
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // 將redisTemplate的序列化方式更改為StringRedisSerializer
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

 

到此，問題解決！
