Redis 使用笔记之 hash

1、RedisClient 类

package com.redis;import redis.clients.jedis.Jedis;/** * Description: Created by Bluesky on 2017/7/18. */public class RedisClient {    private static Jedis jedis;    private RedisClient() {    }    static {        // 连接本地的 Redis 服务        jedis = new Jedis( "localhost" );        jedis.auth( "*******" );    }    public static Jedis getRedisClient() {        return jedis;    }}

2、User 类

package com.redis;import java.io.Serializable;/** * Description: Created by Bluesky on 2017/7/18. */public class User implements Serializable {    private static final long serialVersionUID = 5486841748799373759L;    private Long id;    private String name;    private Integer age;    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }    @Override    public String toString() {        return "User{" +                "id=" + id +                ", name='" + name + '\'' +                ", age=" + age +                '}';    }}

3、使用 hash 存取对象

public static void testMap() {        Jedis jedis = RedisClient.getRedisClient();        User user = new User();        user.setId(3l);        user.setName("Tom3");        user.setAge(28);        String key = "u:3";        try {            jedis.hmset(key, BeanUtils.describe(user));            User user1 = new User();            BeanUtils.populate(user1, jedis.hgetAll(key));            System.out.println(user1.toString());        } catch (IllegalAccessException e) {            e.printStackTrace();        } catch (InvocationTargetException e) {            e.printStackTrace();        } catch (NoSuchMethodException e) {            e.printStackTrace();        }    }
