SpringBoot and IBM MQ connection properties not overrided on deploy - spring-boot

Question

I've a SpringBoot App with a local configuration to connect and listen a local Queue
ibm:
mq:
queueManager: LOCAL_QM
channel: DEV.ADMIN.SVRCONN
connName: localhost(1414)
user: admin
password: passw0rd
user-authentication-m-q-c-s-p: false
When a I deploy the app with Gitlab CI some properties are overrided (with a war_name.xml file in ../tomcat/current/conf/Catalina/localhost/) like database connection properties and mq connection properties to listen a Developpement or Qualification environment queue.
But when the app start the database connection is OK but not the MQ connection (The app use the local connection properties defined in the application.yml file)
When I check the xml file on the remote server, the properties are override.
And when I use a tool like spring actuator, I have the right properties override with the specific env properties.
But in the logs: /tomcat/current/logs/catalina.out I can read that the app try to connect to the local queue manage : LOCAL_QM not the specific environment queue.

The properties are in the same xml file, it works for the database "spring.datasource" but not for MQ "ibm.mq"
<?xml version="1.0" encoding="UTF-8"?>

<Environment name="spring.datasource.username" value="****" type="java.lang.String"/>
<Environment name="spring.datasource.password" value="****" type="java.lang.String"/>
<Environment name="ibm.mq.queueManager" value="***" type="java.lang.String"/>
<Environment name="ibm.mq.channel" value="***" type="java.lang.String"/>
<Environment name="ibm.mq.connName" value="***" type="java.lang.String"/>
<Environment name="ibm.mq.user" value="***" type="java.lang.String"/>
<Environment name="ibm.mq.password" value="" type="java.lang.String"/>
</Context>
Any idea why the properties are not overrided ?
Thanks

This started out as a comment, but as I wrote it I suspected that you are missing the relevant ibm.mq properties. If you don't provide the following properties:
ibm.mq.queueManager
ibm.mq.channel
ibm.mq.connName
ibm.mq.user
ibm.mq.password
then they default to
ibm.mq.queueManager=QM1
ibm.mq.channel=DEV.ADMIN.SVRCONN
ibm.mq.connName=localhost(1414)
ibm.mq.user=admin
ibm.mq.password=passw0rd
ie. localhost.
The mq-jms-spring-boot-starter makes use of
import org.springframework.boot.context.properties.ConfigurationProperties;
#ConfigurationProperties(prefix = "ibm.mq")
to read the connection properties. In this module https://github.com/ibm-messaging/mq-jms-spring/blob/master/mq-jms-spring-boot-starter/src/main/java/com/ibm/mq/spring/boot/MQConfigurationProperties.java
So it relies on spring to make the properties prefixed with ibm.mq available to it. ie. As long as spring through #ConfigurationProperties knows how to handle the overrides it will make them available to mq-jms-spring-boot-starter.
