Java Application on Docker (MySQL + Rabbit) - rabbitmq

Question

I am making an REST API which has a POST method which accepts a String as JSON and then sends it over RabbitMQ Topic and then a consumer is converting into entity and saving into a MySQL db.
Everything is running fine locally, but my task is to upload it on Docker and to be run online.
When I try to change "localhost" in properties with container names my Maven build fails....
How can i fix that?
I am putting my .properties:
spring.main.allow-bean-definition-overriding=true
spring.datasource.url=jdbc:mysql://localhost:3306/rabbit_messages?createDatabaseIfNotExist=true
spring.datasource.username=root
spring.datasource.password=1234
spring.rabbitmq.host = 127.0.0.1
spring.rabbitmq.port = 5672
spring.rabbitmq.username = guest
spring.rabbitmq.password = guest
and my docker-compose:
version: '3'
services:
my-app:
container_name: myapp
build:
context: .
dockerfile: Dockerfile
