java如何在Redis中存储嵌套的Hashmap？

Question

我想将netsted HashMap存储在Redis中，并使用单个键

例如：

HashMap<String, HashMap<String,String>> map = new  HashMap<>();

请建议：

• 有没有办法存储上述数据结构
• 我们如何才能做到这一点

Answer 1

REDIS现在允许嵌套HashMap https://redis.io/topics/data-types

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <version>1.5.22.RELEASE</version>
</dependency>

public class Redis {

    @Autowired
    RedisService redisService;

    @Cacheable(value = "name", key = "keyvalue")
    public Map<String, HashMap<String, String>> redisNestedMap(String keyvalue) {
        return redisService.getNestedMap();
    }

}

@Component
public class RedisService {

    public Map<String, HashMap<String, String>> getNestedMap() {
        Map<String, HashMap<String, String>> nestedMap = new HashMap<>();
        HashMap<String, String> value = new HashMap<>();
        value.put("key", "value");
        nestedMap.put("one", value);
        return nestedMap;
    }

}
