Problems deploying a project with docker - spring

Question

I recently started trying to use the docker in a more advanced way. I had already used it to create mysql server and postgres server containers. At the moment I have a Spring test project, which runs normally when starting up. But I tried to instantiate the same with docker, it successfully creates a mysql server, and instantiates a tomcat, but it does not go up the project itself.
Dockerfile content:
FROM tomcat:9-jre11
ENV CATALINA_OPTS="$CATALINA_OPTS -Duser.timezone=America/Sao_Paulo -Xms1024m -Xmx2560m -XX:+UseParallelGC -XX:-OmitStackTraceInFastThrow"
ADD ./smartCircuit/target/*.war $CATALINA_HOME/webapps/
EXPOSE 8080
CMD catalina.sh run;
docker-compose.yaml content:
version: '3.5'
services:
db:
image: mysql:5.7
restart: always
container_name: mysql-container
environment:
MYSQL_DATABASE: 'smart_circuit'
MYSQL_USER: 'user'
MYSQL_PASSWORD: 'password'
MYSQL_ROOT_PASSWORD: 'password'
ports:
# <Port exposed> : < MySQL Port running inside container>
- '3307:3306'
expose:
# Opens port 3306 on the container
- '3306'
# Where our data will be persisted
volumes:
- my-db:/var/lib/mysql
web:
build: .
container_name: tomcat
ports:
- 8080:8080
environment:
DB_URL: jdbc:mysql://mysql-container:3306/smart_circuit?useSSL=false
DB_USER: user
DB_PASSWORD: password
links:
- db:mysql-container
# Names our volume
volumes:
my-db:
I'm expecting my application to start and be accessible when I use the command "sudo docker-compose up --build". For example I have one RestController mapped "project" with a method mapped "find" which receives an id and either retrieves it when found or throws a NotFoundException.
When I run it through InteliJ without docker it works, but when I start it through docker I get a Tomcat 404 Not Found return.
Basically I can access the mysql instance with no problem and the tomcat is kind of working, but the project itself is not being deployed.
