Spring Boot attributes of the Model are not loaded on JSP page - maven

Question

I'm desperate, i'm following all the tutorials and the documentations, and i succesfully create a little hello controller with spring boot, but when i'm try to use spring boot on my project, all the attributes of the spring Model/Modelview are not loaded and i don't know why.
Here my pom.xml:

}
Here the link to my JSP page: JSPPage
I don't know why but the attribute arrayMarker2 is always empty, and that give me nuts.
You can find the full code of the project to this link springMVC12.
Ty in advance for any help.

Answer 1

Ok, i solved by myself but i not sure how.
I just replace all the Model of springframework with the ModelAndView Object.
