我列出来的都是最常用的，其他的你要自己去搜搜

1. 列表类型数据

java 复制代码

@Autowired
private RedisTemplate<String ,Object> redisTemplate;

public void f1() {
        String k = "key";
        ListOperations<String, Object> list = redisTemplate.opsForList();
        redisTemplate.expire(k, 2, TimeUnit.HOURS);//设置过期时间
        list.rightPush(k,"a");//在尾部插入
        list.leftPush(k,"c");//在头部插入
        List<Object> range = list.range(k, 0, -1);//获取指定范围的列表，在这里获取全部
        System.out.println(range);//输出：[c, a]

        list.set(k,0,"new");//设置列表指定索引的值
        list.set(k,1,"old");
        List<Object> range2 = list.range(k, 0, -1);
        System.out.println(range2);//输出：[new, old]
}

2. 字符串类型数据

java 复制代码

@Autowired
private RedisTemplate<String ,Object> redisTemplate;

@org.junit.jupiter.api.Test
public void f1() {
        String k = "ts";
        ValueOperations<String, Object> operations = redisTemplate.opsForValue();
        redisTemplate.expire(k, 2, TimeUnit.HOURS);
        operations.set(k,"09000");
        System.out.println(operations.get(k));//09000
}

3. 有序集合类型数据

java 复制代码

@Autowired
private RedisTemplate<String ,Object> redisTemplate;

@org.junit.jupiter.api.Test
public void f1() {
        String k = "dc";
        SetOperations<String, Object> set = redisTemplate.opsForSet();
        redisTemplate.expire(k, 2, TimeUnit.HOURS);
        set.add(k,"a");
        set.add(k,"b");
        set.add(k,"c");
        System.out.println(set.members(k));//获取集合的所有元素，输出：[a, b, c]
}
