How to get current term in my custom taxonomy in WordPress?

I need to display the current term in my custom taxonomy in a single post.

example:

• My custom taxonomy is products and term of them is product-1, product-2 and products-3.
• My post is assigned to product-2
• And I want to print the current products = products-2 in my post

In fact, I need a function like WordPress’s the_category(); but for my taxonomy like the_customtaxonomy();

UPDATE :

in facts i know i need to get id of this becuse i need to show a icon for this in my single , for example a function like the_category_ID();

You can use get_the_term_list():

Description

Usage

<?php get_the_term_list( $id, $taxonomy, $before, $sep, $after ) ?>
