spring boot data redis如何将hashmap改成Model

Question

我是 spring 和 spring 引导新手，我现在正在使用 spring data redis。

我有这样的模型

@Entity
@Table(name = "users")
public class User {
    private Long id;

    @Id
    @javax.persistence.Column(name = "id", nullable = false, insertable = true, updatable = true)

    private String email;

    @Basic
    @javax.persistence.Column(name = "email", nullable = false, insertable = true, updatable = true, length = 128)

   //some other fields and getters and setters

}

在redis中，我们使用hash store User Model，像这样。关键是：u_id

redis-cli> hgetall u_19999
  1) "id"
  2) "19999"
  3) "email"
  4) "xx@gmail.com"
  5) "weblink"
  6) "www.google.com"

在spring启动数据redis

HashOperations<String, String, String> hashOperations = this.stringRedisTemplate.opsForHash();
String key = "u_"+userId;
Map<String, String> userMap = hashOperations.entries(key);

现在，userMap 是一个 hashmap，包含 Model User 的字段，现在我想将 userMap 更改为 Model User

我该怎么办？

提前致谢。

Answer 1

首先获取所有字段

 HashOperations<String, String, String> hashOperations =            this.stringRedisTemplate.opsForHash();
 String key = "u_"+userId;
 Map<String, String> userMap = hashOperations.entries(key);

使用 BeanUtilsHashMapper class

HashMapper<User, String, String> mapper = new BeanUtilsHashMapper<User>(User.class);
return mapper.fromHash(userMap);
