As long as your getters and setters are correctly set up, you can dot-walking to access inner objects and properties:

<span th:text="${class1.class2.attribute1}" />
<span th:text="${class1.class3.attribute2}" />

If you are using those attributes in a form, the same works for input fields. For example:

<form th:object="${class1}">
    <input type="text" th:field="*{class2.attribute1}" />
</form>

The answer of Metroids seems to be correct. If you get an error, make sure again you have getters and setters in your Java classes and their modifier are public. Missing it is a common mistake.
Also make sure this attributes are exists and you did not misstype it. If you get NullPointerException, you should use #{objects.nullsafe(variable)} or use ?s like this:
<td th:text="${user?.address?.street}"></td>

The ? means this object or attribute can be null.
I hope I could help you. :)
