Spring Data Redis中提供了一个高度封装的类：RedisTemplate，对相关api进行了归类封装,将同一类型操作封装为operation接口，具体分类如下：

• ValueOperations：string数据操作

• SetOperations：set类型数据操作

• ZSetOperations：zset类型数据操作

• HashOperations：hash类型的数据操作

• ListOperations：list类型的数据操作

• GeoOperations: geo地址位置数据类型的操作

• HyperLogLogOperations: HyperLogLog基数类型的操作

• ValueOperations：bitmap数据操作(bitmap的本质还是基于string类型的value)

• 字符串(string)：普通字符串，Redis中最简单的数据类型

• 哈希(hash)：也叫散列，类似于Java中的HashMap结构

• 列表(list)：按照插入顺序排序，可以有重复元素，类似于Java中的LinkedList

• 集合(set)：无序集合，没有重复元素，类似于Java中的HashSet

• 有序集合(sorted set/zset)：集合中每个元素关联一个分数(score)，根据分数升序排序，没有重复元素

	/*** 操作字符串类型的数据*/@Testpublic void testString(){// set get setex setnxredisTemplate.opsForValue().set("name","小明");String city = (String) redisTemplate.opsForValue().get("name");System.out.println(city);redisTemplate.opsForValue().set("code","1234",3, TimeUnit.MINUTES);redisTemplate.opsForValue().setIfAbsent("lock","1");redisTemplate.opsForValue().setIfAbsent("lock","2");}

	/*** 操作哈希类型的数据*/@Testpublic void testHash(){//hset hget hdel hkeys hvalsHashOperations hashOperations = redisTemplate.opsForHash();hashOperations.put("100","name","tom");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");}

/*** 操作列表类型的数据*/@Testpublic void testList(){//lpush lrange rpop llenListOperations listOperations = redisTemplate.opsForList();listOperations.leftPushAll("mylist","a","b","c");listOperations.leftPush("mylist","d");List mylist = listOperations.range("mylist", 0, -1);System.out.println(mylist);listOperations.rightPop("mylist");Long size = listOperations.size("mylist");System.out.println(size);}

/*** 操作集合类型的数据*/@Testpublic void testSet(){//sadd smembers scard sinter sunion sremSetOperations setOperations = redisTemplate.opsForSet();setOperations.add("set1","a","b","c","d");setOperations.add("set2","a","b","x","y");Set members = setOperations.members("set1");System.out.println(members);Long size = setOperations.size("set1");System.out.println(size);Set intersect = setOperations.intersect("set1", "set2");System.out.println(intersect);Set union = setOperations.union("set1", "set2");System.out.println(union);setOperations.remove("set1","a","b");}

	/*** 操作有序集合类型的数据*/@Testpublic void testZset(){//zadd zrange zincrby zremZSetOperations zSetOperations = redisTemplate.opsForZSet();zSetOperations.add("zset1","a",10);zSetOperations.add("zset1","b",12);zSetOperations.add("zset1","c",9);Set zset1 = zSetOperations.range("zset1", 0, -1);System.out.println(zset1);zSetOperations.incrementScore("zset1","c",10);zSetOperations.remove("zset1","a","b");}

操作Geospatial地理位置类型**
@Test
public void geoTest(){GeoOperations geoOperations = redisTemplate.opsForGeo();geoOperations.add("location",new Point(114.400,40.121),"shop");geoOperations.add("location",new Point(114.400,40.122),"shop2");List position = geoOperations.position("location", "shop");System.out.println(position);
}

操作HyperLogLog基数统计类型**
@Test
public void loglogTest(){HyperLogLogOperations logOptions = redisTemplate.opsForHyperLogLog();logOptions.add("userIds","a","b","c","d");Long total = logOptions.size("userIds");System.out.println("访客数："+total);
}

操作bitmap二进制位类型**
@Test
public void stringTest(){ValueOperations stringOptions = redisTemplate.opsForValue();//bitmap操作stringOptions.setBit("bitmap",50,true);Boolean bool = stringOptions.getBit("bitmap", 50);System.out.println(bool);}

/*** 根据类型查询分类* @param type* @return*/@Autowiredprivate RedisTemplate redisTemplate;public List<Category> list(Integer type) {//  添加redis缓存List<Category> list =  (List<Category>)redisTemplate.opsForValue().get(RedisConstant.CATEGORY_LIST+type);if(list==null||list.size()==0) {list = categoryMapper.list(type);redisTemplate.opsForValue().set(RedisConstant.CATEGORY_LIST+type,list);}return list;}
