【Redis】09 Jedis 03 Hash与Java对象

创建一个普通对象类：

public class User implements Serializable {
    private String name;
    private String password;
    private int age;
    private boolean gender;
    // 省略 getter & setter constructor & toString ...
}

测试：

    @Test
    public void testRedisHashtStructureWithJavaObject(){
        User user = new User("entity-user", "123456", 23, false);

        Jedis jedis = CustomJedisPool.getJedis();

        /* 写入方式 */

        // 方式一
        jedis.hset("user:01", "name", user.getName());
        jedis.hset("user:01", "password", user.getPassword());
        jedis.hset("user:01", "age", String.valueOf(user.getAge()));
        jedis.hset("user:01", "gender", Boolean.toString(user.isGender()));

        // 方式二
        Map<String, String> objectMap = new HashMap<String, String>();
        objectMap.put("name", user.getName());
        objectMap.put("password", user.getPassword());
        objectMap.put("age", String.valueOf(user.getAge()));
        objectMap.put("gender", Boolean.toString(user.isGender()));
        jedis.hmset("user:02", objectMap);

        /* 读取方式 */

        if (jedis.exists("user:01")) {
            Map<String, String> stringStringMap = jedis.hgetAll("user:01");
            for (String s : stringStringMap.keySet()) {
                System.out.println(s + " : " + stringStringMap.get(s));
            }
        }
        if (jedis.exists("user:02")) {
            Map<String, String> stringStringMap = jedis.hgetAll("user:02");
            for (String s : stringStringMap.keySet()) {
                System.out.println(s + " : " + stringStringMap.get(s));
            }
        }

    }

结果：
