test-on-borrow config in hikariCP

I have spring boot 2.0.2.RELEASE project and I want configure datasources with pool connection.
I use Spring data JPA + hibernate + HikariCP:
#DataBase properties
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=***
spring.datasource.username=*****
spring.datasource.password=*****
# Hikari
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=20
spring.datasource.hikari.idleTimeout=30000
spring.datasource.hikari.poolName=SpringBootJPAHikariCP
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000
spring.datasource.hikari.connection-test-query=SELECT 1
#jpa config
spring.jpa.hibernate.ddl-auto=validate
spring.jpa.show-sql=true
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.data.jpa.repositories.enabled=true
In #DataBase properties - I think everything is fine
In #Hikari - I do not know how implement this:
in tomcat I can write spring.datasource.tomcat.test-on-borrow=true but how can I make like this with Hikari ?
And mayby I forgote some important configs?

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:

You might want to clean up your dependencies. Perhaps it's sufficient to pull spring-beans up to 4.3

Defining and Removing Spring Boot / Spring JPA Datasources Programmatically at Runtime?

I need to create Spring Boot Datasources dynamically at runtime. Anyone know how to do this. Effectively I need to do this on demand:
spring:
datasource:
url: jdbc:h2:mem:testdb1;
username: sa
password:
driver-class-name: org.h2.Driver
platform: h2
spring:
datasource:
url: jdbc:h2:mem:testdb2;
username: sa
password:
driver-class-name: org.h2.Driver
platform: h2
...
spring:
datasource:
url: jdbc:h2:mem:testdbN;
username: sa
password:
driver-class-name: org.h2.Driver
platform: h2
Thoughts?

Try below way to create data-source programmatically
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl("jdbc:h2:mem:testdb1");
dataSource.setUsername("sa");
dataSource.setPassword("");
dataSource.setDriverClassName("org.h2.Driver");

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.

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.

Spring Boot 1.2.1.RELEASE and JNDI Errors

I receive an error when I deploy my web application, using IntelliJ 14.0, to a local Apache Tomcat instance. I am using Spring Boot 1.2.1.RELEASE and with a JNDI connection.
The contents of my application.yaml file looks like this:
spring:
profiles:
active: production
---
spring:
profiles: development
datasource:
platform: h2
---
spring:
profiles: production
datasource:
jndi-name: java:/comp/env/jdbc/teams
platform: mysql
jpa:
hibernate:
ddl-auto: create-drop
My configuration file, Application.java, looks like this:
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
I am using Apache Tomcat 8.0.15 and have configured a JNDI connection in the context.xml file.
<Resource name="jdbc/teams" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="***" password="***" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/teams"/>
I am using IntelliJ 14.0 to deploy my application locally to Apache Tomcat using the production profile.
The error I receive when when I attempt to deploy the application is as follows:
org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [org.apache.tomcat.dbcp.dbcp2.BasicDataSource#4f83492a] with key 'dataSource'; nested exception is javax.management.InstanceAlreadyExistsException: Catalina:type=DataSource,host=localhost,context=/project,class=javax.sql.DataSource,name="jdbc/teams"
What could be wrong with the way the application is configured?

I modified the application.yaml file and the application is now working. I added spring.jmx.enabled and spring.jpa.database-platform properties to the application.yaml file.
