SpringBoot Failed to configure a DataSource

I'm currently learning microservices. After creating my first microservice, I tried to connect my microservice to a PostgreSQL database but I have the following error:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
With this exception:
Exception encountered during context initialization - cancelling
refresh attempt:
org.springframework.beans.factory.UnsatisfiedDependencyException:

Here's my application.yml
server:
port: 8080
spring:
application:
name: player
datasource:
password: "MySecretPassword!"
url: jdbc:postgresql://localhost:5432/genjiservices
username: saucegenji
jpa:
hibernate:
ddl-auto: update
properties:
hibernate:
dialect: org.hibernate.dialect.PostgreSQLDialect
format_sql: true
show-sql: true
I couldn't post my pom because it says it was a spam.
I tried to find solutions first, but couldn't find one that works for me. I think my application is ignoring my application.yml could that be the case? My application.yml is in the resources folder like it should be, so I don't really understand.

Check if the following is present in the pom file.Also check for JPA dependencies in pom.
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>

Spring boot: maven package with specific profile

The goal is, to have dev and prod environments. For the local run to use application-dev.yml and for deploying to the server to use application-prod.yml
I have 3 configuration files
application.yml
spring:
main:
banner-mode: off
application-dev.yml
spring:
datasource:
password: dev-user-pwd
username: dev-user
url: jdbc:mysql://localhost:3306/db
driver-class-name: com.mysql.cj.jdbc.Driver
application-prod.yml
spring:
datasource:
password: prod-user-pwd
username: prod-user
url: jdbc:mysql://localhost:3306/db
driver-class-name: com.mysql.cj.jdbc.Driver
In the server, I have maven installed and trying to run
mvn clean package -Dspring.profiles.active=prod
Here is the error log that I'm getting
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 10.966 s <<< FAILURE! - in com.partplug.api.ApiApplicationTests
contextLoads Time elapsed: 0.005 s <<< ERROR!

In short: the error says that, datasource and all sub-properties are not defined. Meaning, maven packager doesn't change the active profile to prod.
What am I doing wrong?

java.lang.NoClassDefFoundError: org/springframework/beans/factory/config/EmbeddedValueResolver

I've recently managed to upgrade a jhipster generated app (Spring Boot + Angular)
Issue comes after cleaning code and adapting a few annotations, now I get success when doing a maven clean - install skipping tests but when I try to start the app I get the error mentioned in the title
I've checked pom for duplicated dependencies and had a clean out of the properties file, to no result
This is the full error:

</dependency>
<dependency>

Check for these dependencies as well

Can you add runtime dependency in gradle as opposed to compile time dependency on the MYSQL Driver jar ?
dependencies {
//compile "mysql:mysql-connector-java:6.0.3"
runtime "mysql:mysql-connector-java:6.0.3"
runtime "org.apache.tomcat:tomcat-jdbc:7.0.47"
}

do you have database driver on the classpath?
have you set property spring.datasource.driver-class-name?

Grails 3.0.4 deploying localhost but not remotely

Someone help please...I am able to run:
grails run-app
and access my application on localhost:8080. However, I have no luck deploying to Tomcat 7.052 on Ubuntu 14.04.1LTS. The war file uploads successfully using the Tomcat Web Manager but I get HTTP error 404 upon accessing via the browser. I am clicking on the application link on the Tomcat Web Manager to access the applications. I tried deploying the sample.war file from Tomcat examples and it works.
Here is what I have tried:
1) I changed my build.gradle file from:
...
compile "org.springframework.boot:spring-boot-starter-tomcat"
...
to:
...
provided "org.springframework.boot:spring-boot-starter-tomcat"
...
2) I ran:
grails war
to generate a war file in which I then uploaded successfully using Tomcat Web Manager.
3) I also tried restarting the tomcat service.
Here is my grails-app/conf/application.yml file:

After digging into the log files (catalina.out) embedded below, I found out that Tomcat was using Java 7 whilst my grails application had used Java 8. Here is what I did:
1) I installed Java 8 on my server and set Tomcat to use it. This has significantly slowed down my Tomcat though.
2) I then configured my dataSource in grails-app/conf/application.yml to include the correct configurations for MySQL database. These configuration are in Grails 3.x documentation under dataSource.
3) Lastly, I included
runtime 'mysql:mysql-connector-java:5.1.29'
in my gradle.build dependencies.
