问如何将获取的Google cloud数据存储实体(com.google.cloud.datastore.Entity)映射到自定义Java对象

EN

Query<Entity> query = Query.newEntityQueryBuilder()
                .setNamespace("abc")
                .setKind("ca")
                .setFilter(StructuredQuery.PropertyFilter.eq("name", "xyz"))
                .build();

QueryResults<Entity> tasks = datastore.run(query);

for (QueryResults<Entity> it = tasks; it.hasNext(); ) {
            Entity entity = it.next();
            User user = entity.toUser();//How to map to my custom Java class
        }
