// 首先要定义一个BoundHashOperations
BoundHashOperations<String, String, Object> boundHashOperations = redisTemplate.boundHashOps("li");
// 1、put(HK key, HV value)：新增元素到指定键中
boundHashOperations.put("ww","i");
boundHashOperations.put("w1","i1");
boundHashOperations.put("w2","i2");
// 2、getKey()：获取指定键中的值
System.out.println("获取设置的绑定key值:" + boundHashOperations.getKey());
// 3、values()：获取map中的值jdk要求1.8及以上
boundHashOperations.values().forEach(v -> System.out.println("获取map中的value值" + v));
// 4、entries()：获取map中的键值对
boundHashOperations.entries().forEach((m,n) -> System.out.println("获取map键值对:" + m + "-" + n));
// 5、get(Object member)：获取map键中的值
System.out.println("获取map建的值:" + boundHashOperations.get("w1"));
// 6、keys()：获取map的键
boundHashOperations.keys().forEach(v -> System.out.println("获取map的键:" + v));
// 7、multiGet(Collection<HK> keys)：根据map键批量获取map值
List list = new ArrayList<>(Arrays.asList("ww","w1"));
boundHashOperations.multiGet(list).forEach(v -> System.out.println("根据map键批量获取map值:" + v));
// 8、putAll(Map<? extends HK,? extends HV> m)：批量添加键值对
Map map = new HashMap<>();
map.put("m1","n1");
map.put("m2","n2");
boundHashOperations.putAll(map);
boundHashOperations.entries().forEach((m,n) -> System.out.println("批量添加键值对:" + m + "-" + n));
// 9、increment(HK key, long delta)：自增长map键的值
boundHashOperations.increment("c",1);
System.out.println("自增长map键的值:" + boundHashOperations.get("c"));
// 10、putIfAbsent(HK key, HV value)：添加不存在的map键
boundHashOperations.putIfAbsent("m2","n2-1");
boundHashOperations.putIfAbsent("m3","n3");
boundHashOperations.entries().forEach((m,n) -> System.out.println("新增不存在的键值对:" + m + "-" + n));
// 11、size()：获取特定键对应的map大小
System.out.println("查看绑定建的map大小:" + boundHashOperations.size());
// 12、scan(ScanOptions options)：扫描特定键所有值
Cursor<Map.Entry<String, Object>> cursor = boundHashOperations.scan(ScanOptions.NONE);
while (cursor.hasNext()){
    Map.Entry<String, Object> entry = cursor.next();
    System.out.println("遍历绑定键获取所有值:" + entry.getKey() + "---" + entry.getValue());
}
// 13、delete(Object... keys)：批量删除map值
long delSize = boundHashOperations.delete("m3","m2");
System.out.println("删除的键的个数:" + delSize);
boundHashOperations.entries().forEach((m,n) -> System.out.println("删除后剩余map键值对:" + m + "-" + n));
