Spring Data Redis 的使用方法

使用前需要开启Redis服务。

操作步骤：

一. 导入Spring Data Redis的maven坐标

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>

二. 配置Redis数据源

sky:redis:host: localhostport: 6379password: ****database: 0

三. 编写配置类，创建RedisTemplate对象

@Configuration
@Slf4j
public class RedisConfiguration {@Beanpublic RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){log.info("开始创建RedisTemplate对象...");RedisTemplate redisTemplate = new RedisTemplate();// 设置redis连接工厂对象redisTemplate.setConnectionFactory(redisConnectionFactory);// 设置redis key的序列化器redisTemplate.setKeySerializer(new StringRedisSerializer());return redisTemplate;}
}

四. 通过RedisTemplate操作Redis

这里以字符串和hash为例：

    @Autowiredprivate RedisTemplate redisTemplate;/*** 操作字符串*/@Testpublic void testString(){ValueOperations valueOperations = redisTemplate.opsForValue();valueOperations.set("name","张三");String name = (String) valueOperations.get("name");System.out.println(name);valueOperations.set("code","123456",3, TimeUnit.MINUTES);valueOperations.setIfAbsent("code","123456");}/*** 操作hash*/@Testpublic void testHash(){//hset hget hdel hkeys hsize hvaluesHashOperations hashOperations = redisTemplate.opsForHash();hashOperations.put("100","name","szj");hashOperations.put("100","age",20);String name = (String) hashOperations.get("100", "name");System.out.println(name);Set keys = hashOperations.keys("100");System.out.println(keys);List values = hashOperations.values("100");System.out.println(values);hashOperations.delete("100","age");}
