Spring Application gets 404 error on TomCat-CodePudding

how are u?

I'm doing a Spring Boot Application and i'm getting the 404 error on TomCat. I'm using Maven to build the .WAR file and do the deploy to TomCat with the tomcat7-maven-plugin. I already read a lot of topics with a context very similar to mine but i cant find a solution. Something that i notice, is that when i do the deploy, the Spring Letters not show anymore on TomCat prompt.

HTTP Status 404 – Not Found
Type Status Report

Message The requested resource [/scim/] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.64

Print of the error

Some dudes try to resolve this putting extends SpringBootServletInitializer and the

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder){
    return builder.sources(ScimApplication.class);
}

on the main class, but i already did that, and didn't worked.

I used to compile the .war file with the mvn clean install command, then i do the mvn clean tomcat7:deploy to do the deploy directly to the TomCat, that i already configurated the user on tomcat-users.xml, and add the server tag on the settings.xml on conf folder of Maven.

Even if i enter on the TomCat's manager page, and do the deploy from there, when i try localhost:8080/scim, i get 404 error.

I will put my initialization TomCat log here, as well my Controller, POM.xml and Main class.

Thank you and if you guys need more information, just tell me.
