  <dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.12</version></dependency></dependencies>

测试

  @Testpublic void Test1() {
//    连接RedisJedis jedis = new Jedis("localhost", 6379);
//    操作Redis - 因为Redis命令是什么,Jedis方法就是什么jedis.set("name", "李四");
//    释放资源jedis.close();System.out.println(jedis.get("name"));}

存入对象

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User  implements Serializable {private String name;private String Date;
}

测试

  @Testpublic void Test2() {
//    连接RedisJedis jedis = new Jedis("localhost", 6379);
//    准备key(String) -value (user)String key = "user";User value = new User("张三", "1999");
//    将key和value转换为byte[]byte[] byteKey = SerializationUtils.serialize(key);byte[] byteValue = SerializationUtils.serialize(value);
//    将key和value存储到Redisjedis.set(byteKey, byteValue);
//    释放资源jedis.close();

读取对象

@Testpublic void Test3() {
//    连接RedisJedis jedis = new Jedis("localhost", 6379);
//    准备一个keyString key = "user";
//    将key转换为字节数组类型byte[] byteKey = SerializationUtils.serialize(key);
//    jedis去redis中获取valuebyte[] value = jedis.get(byteKey);
//    将value反序列化User user = (User) SerializationUtils.deserialize(value);System.out.println(user);
//    释放资源jedis.close();}

测试

  @Testpublic void test1(){
//    连接RedisJedis jedis = new Jedis("localhost",6379);
//    准备key(String) - value(User)String key = "stringUser";User value = new User("帅哥","19999");
//    使用fastJSON将value转换为json字符串String stringValue = JSON.toJSONString(value);
//    存储到Redis中jedis.set(key,stringValue);
//    释放资源jedis.close();}

获取字符串格式

 @Testpublic void test2(){
//    连接RedisJedis jedis = new Jedis("localhost",6379);
//准备一个keyString key = "stringUser";//去Redis中查询valueString value = jedis.get(key);//将value反序列化一个对象User user = JSON.parseObject(value, User.class);System.out.println("user = "+ user);
//    释放资源jedis.close();}
