Jedis存储一个以byte[]的形式的对象到Redis

1.1 准备一个User实体类

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;
import java.util.Date;@Data
@NoArgsConstructor
@AllArgsConstructor
public class User implements Serializable {private Integer id;private String name;private Date birthday;
}

1.2 导入Maven依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId><exclusions><exclusion><groupId>io.lettuce</groupId><artifactId>lettuce-core</artifactId></exclusion></exclusions>
</dependency>
<!--  切换 jedis 作为操作redis的底层客户端-->
<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId>
</dependency>
<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional>
</dependency>

1.3 创建TestSetByteArray测试类，编写内容

import org.springframework.util.SerializationUtils;
import redis.clients.jedis.Jedis;import java.util.Date;public class TestSetByteArray {// Redis服务器信息private static final String REDIS_HOST = "192.168.200.141";private static final int REDIS_PORT = 6379;private static final String REDIS_PASSWORD = "sl183691";public static void main(String[] args) {//1. 连接RedisJedis jedis = new Jedis(REDIS_HOST, REDIS_PORT);jedis.auth(REDIS_PASSWORD);//2.1 准备key(String)-value(User)String key = "user";User value = new User(1, "张三", new Date());//2.2 将key和value转换为byte[]byte[] byteKey = SerializationUtils.serialize(key);byte[] byteValue = SerializationUtils.serialize(value);//2.3 将key和value存储到Redisjedis.set(byteKey, byteValue);System.out.println("===================================================");//3. 获取操作结果//3.1 jedis去Redis中获取valuebyte[] value2 = jedis.get(byteKey);//3.2 将value反序列化为User对象User user = (User) SerializationUtils.deserialize(value2);//3.3 输出System.out.println("user:" + user);//4. 释放资源jedis.close();}
}

测试结果：
