When I start my spring boot application, my database is not initiating

I have one spring-boot test application in which I provide the following configuration in application.yml file. when I start my server using mvn test, it doesn't initiate the database connection, what can be the issue here? Am I missing any dependency in pom.xml?
spring.datasource.driverClassName = com.ibm.db2.jcc.DB2Driver
spring.datasource.url=jdbc:db2://<fullURL>
spring.datasource.username = <uname>
spring.datasource.password = <password>
Following are my dependencies related to spring-boot
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
Here are my boot logs in which I don't see the database connection logs

Couple of things I note:
You are mentioning application.yml but the format of the file is properties
You need to add the Driver in your dependencies for Spring Boot to pick up as well.
If you are running test, and have an applicatio.yml in src/test/resources, it will override the one in src/main/resources

Can I create a SpringBootApplication in src/test/java?

We want to run some remote tests in Docker. Our idea was to create a SpringBootApplication that will run the tests and report the results and we will have this Application deployed in it's own Docker with it's own JAR.
To make sure that it does not ship with the main code (src/main/java) we want to have this code in src/test/java..
From the documentation this does not appear possible from the Spring-boot-maven-plugin.
So now I am trying to create a test-jar but when I run the Application class I get

Is there any documentation on how to package a SpringBoot Application without the maven plugin?

It turns out all I needed to do as add a file to my source repo
src/main/resources/META-INF/spring.factories
You can grab a copy from here
All thanks to the answer from another post related the question

Tomcat redeploy not completely reloading webapp

Using Apache Tomcat/8.5.24, running a Spring Boot application.
When we use the tomcat manager page and click "Reload" on our web-app, the app is not reloaded. catalina.out says that the context has been reloaded, but Spring does not fire and our endpoints don't respond. In order to get a real reload, we have to completely un-deploy the web app and re-deploy from scratch, which is less than ideal.
When I first deploy the app, I get the familiar

Splash screen and all the associated controller bindings and bean creation logs. However, when I click "reload", I get this

And that's it.
We are using external jars, defined in a context.xml file as follows:
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myapp" docBase="/myapp" reloadable="true">
<Resources>
<!-- Load the configuration files -->
<!-- Location of external log4j2 configuration file -->
<PreResources className="org.apache.catalina.webresources.DirResourceSet"
base="/mycompany/libs/config/"
webAppMount="/WEB-INF/classes" />
<!-- Location of the JARs -->

base="/mycompany/libs/application_core/"
webAppMount="/WEB-INF/lib" />
<JarResources className="org.apache.catalina.webresources.DirResourceSet"
base="/mycompany/libs/application_supplemental/"
webAppMount="/WEB-INF/lib" />
<JarResources className="org.apache.catalina.webresources.DirResourceSet"
base="/mycompany/libs/third_party/"
webAppMount="/WEB-INF/lib" />
</Resources>
</Context>
Before we moved to this structure, this wasn't an issue so I assume it has something to do with this configuration but I'm not extremely familiar with all things tomcat and am not sure where to even look.

IntelliJ Debug as vs java -jar Spring Boot application

When I run a Spring Boot 1.3.5 application from console via java -jar target xxxx.jar, it runs perfectly. Instead, when I run it from my IntelliJ going to the Application class, right-click on class name and Debug as 'Application.main()', it starts and stops really fast. I can only get to see the following message.
Connected to the target VM, address: '127.0.0.1:35472', transport: 'socket'
SLF4J: The requested version 1.7.16 by your slf4j binding is not compatible with [1.6]

Why isn't it working as always (first time I see this problem)?. I'd like to be able to wun my application in debug mode from my IntelliJ.

Spring boot with custom logback configuration

I'm trying to provide some custom logging levels to the default logback configuration, but it seems my configuration file is being ignored. I though Boot may skip it for whatever reason but if I make the file not valid (remove / of self-closing tag for example) I got an exception about not being able to parse it - so it is being picked up.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!-- Spring boot base -->
<include resource="org/springframework/boot/logging/logback/base.xml" />
<logger name="com.wedgetail" level="WARN" />
<logger name="nv" level="WARN" />
<logger name="StatsLogger" level="WARN" />
</configuration>
So for testing purposes (as my loggers are may be wrongly spelled or whatever) I included:
<logger name="org.springframework" level="ERROR" />
When the application comes up I still see spring logging on info level:

Upgrade to Spring Boot 1.1.6. for a fix of this issue.
