Error creating bean with name 'resourceHandlerMapping'

I am implementing Spring Boot application and when it's run from Intellij everythinks works fine, but when the artifact is built and run, gets the next error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'resourceHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'resourceHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: No ServletContext set

See here full log.
I'm using spring-boot-starter-web package which includes Tomcat as a default implementation of a servlet. Seems that exception is thrown because the bean which extends WebMvcConfigurationSupport is created earlier than expected and before the ServletContext is available.
I was trying to change or remove some annotations on WebConfig.java, SecurityConfig.java and CoreApplication.java but always the result is the same.
As a test, if #EnableAutoConfiguration(exclude = { WebMvcAutoConfiguration.class }) is implemented on CoreApplication.java, the exported jar is runned as standalone application without any issue.
So how can I configure WebMvcAutoConfiguration.class in order to run the application waiting for incoming http requests? How can I do in order to build later the bean which extends WebMvcConfigurationSupport and after the ServletContext is available?
Here my repo where there is pom.xml, application.properties, config classes, controllers, main application, models and repositories.
Thanks

There was some problem when build jar from Build -> Build Artifacts -> Rebuild. Seems that tomcat is not embeeded with this configuration.
If I build jar from maven menu into Intellij, the exception dissapear.

Unable to make hot-reloadable config work in Springboot

I followed the last posts described on How to hot-reload properties in Java EE and Spring Boot?
However I'm facing building issues when the context is being initialized.
Can someone try out the code from the post and advise why I'm facing below error ?

Spring Boot REST - MYSQL connection not working

I am trying to follow a simple sample app tutorial to create a spring boot app and connect it to a mysql database. Using IntelliJ ide. https://www.youtube.com/watch?v=YVl6M5ztOu8
Project Structure:
src/main/java/com.example.crudSample
src/main/java/com.example.crudSample/controller/ApiController
src/main/java/com.example.crudSample/models/User
src/main/java/com.example.crudSample/repo/UserRepo
src/test/java/com.example.crudSample/CrudSampleApplicationTests.java
When I try to run this sample app I get the following error message:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.RuntimeException: Failed to load driver class com.mysql.cj.jdbc.Driver in either of HikariConfig class loader or Thread context classloader
**Steps Taken To Run The Program:
Create connection in mysql workbench called "restfulapi"
parameters are root with localhost port 3306, user is admin
Test Connection: Successfully Made MYSQL Connection (was not prompted for a password when clicking)
Click on Connection on MySQL Workbench (did not prompt for a password when clicking connection), and create a crudusers schema
Run the spring program using the application runner class
Received the error message**

server.servlet.encoding.enabled=true
server.servlet.encoding.force=true
Could change the name of DB in my case is "snapchat"
you should the add this dependency on pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.23</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.3.5</version>
</dependency>

Solved the issue by removing the scope tag for the dependency in the pom.xml file and then refreshing the pom.xml file.
Old Code:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
New Code:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

You should also specify the connector for mysql
spring.datasource.driver-class=com.mysql.jdbc.Driver
I think this should fix it.

Upgrading SpringBoot 2.1.4.Relase to 2.5.0 giving NoClassDefFoundError

I am trying to upgrade our gradle spring boot application from 2.1.4.RELEASE to 2.5.0, it builds fine, but when I am trying to do a gradle bootrun, it is giving the following error below.

Errors in spring-boot project

Snippet from aplication.properties file:
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/Petlodgeplatform?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&server
spring.datasource.username=root
spring.datasource.password=root1
spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql=true
debug = true
server.port = 9191

Try modifying the application.properties file.
spring.datasource.hikari.jdbc-url=jdbc:mysql://localhost: 3306/Petlodgeplatform?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&server
spring.datasource.hikari.password=root
spring.datasource.hikari.username=root1
spring.datasource.hikari.driver-class-name=com.mysql.cj.jdbc.Driver

Your version of mysql-connector-java and the diver class don't match. check here for more https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-api-changes.html.
So, you remove the version as:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
The dialect changes as well to org.hibernate.dialect.MySQL8Dialect
