I'm new to spring and I'm practicing but I don't understand this error in console.

I tried to run the program and I get that error, it was to see if the program was working correctly and to see Swagger in action.
I need help to be able to solve the problem. I know it may be due to compatibility errors, but I don't know how to fix it.


Probably version of Spring boot and version of swagger does not match. Instead of Swagger dependencies you can use
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.12</version>
</dependency>
My spring boot version is 2.6.4
You need configuration like this, no need EnableSwagger.

If you want to use mysql you have to add mysql driver:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

The spring-boot-starter-data-jpa artifact can integrate with H2 embedded database. Add the following dependencies to your POM.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
then, add two script files into the src/main/resources folder:
schema.sql for creating the database
data.sql for populating the database
Note that with spring data JPA you get a default configuration for embedded database. You do not need to add database configuration to the application.properties file.

Add this version of derby in pom.xml:
<dependency>
<groupId>org.apache.derby</groupId>
<artifactId>derby</artifactId>
<version>10.11.1.1</version>
<scope>runtime</scope>
</dependency>
After making changes in pom.xml, force update the maven project
And add the following in applications.properties file:
#JPA
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database=default
spring.jpa.show-sql=true
#DATASOURCE
spring.datasource.continue-on-error=false
spring.datasource.generate-unique-name=false
spring.datasource.username=app
Maybe problem with the earlier default derby jar dependency
It worked after making the above changes

Spring Boot Application immediately shuts down after starting in external TOMCAT

Can someone help me please?

It's hard to say out of the information you've provided, but what looks suspicious to me is that you're using spring-boot-starter-web which in turn brings tomcat starter transitively.
I see that the packaging of this module is WAR, so its intended to run in an external web container, but on the other hand, you say that it runs fine in "JAR with embed too".
So it's a little bit confusing.
I've never by myself deployed spring boot application as a WAR file, but I believe you can go to Start.spring.io and generate a sample application that will package itself into WAR. This option is not shown by default, so you'll have to click on "switch to the full version" link

There is a known issue with IntelliJ IDEA Maven support and provided dependencies.
A workaround for your problem would be to change spring-boot-starter-tomcat dependency scope from provided to compile.
See also a related discussion for a similar case, but with a different dependency.

IntelliJ Process finished with exit code 0 when spring-boot run

I have a problem when starting spring-boot appication from IntelliJ-Idea. I don't have this problem when running application through terminal.
:: Spring Boot :: (v1.2.1.RELEASE)
2015-09-24 12:22:44.274 WARN 22380 --- [ main] n.sf.ehcache.config.CacheConfiguration : Cache 'publicationsCount' is set to eternal but also has TTI/TTL set. To avoid this warning, clean up the config removing conflicting values of eternal, TTI and TTL. Effective configuration for Cache 'publicationsCount' will be eternal='true', timeToIdleSeconds='0', timeToLiveSeconds='0'.
Process finished with exit code 0
I think this warn is not causing it. What may be the reason?

Deleting provided scope of spring-boot-starter-tomcat dependency helps me.
<dependency>

I create a simple project from https://start.spring.io/ (sprint initializr) and added a simple controller to run the application.
#RestController

public String hello(){
return "Hello World!!";
}
}

</dependency>

If you create a project gradle template from https://start.spring.io/ (sprint initializr), you need to add org.springframework.boot:spring-boot-starter-web dependecy in you build.gradle file.
// you need to add this dependency to run spring boot correctly
implementation 'org.springframework.boot:spring-boot-starter-web'

Using the below dependencies in pom.xml, as well as loading maven changes (ctrl+shift+o) solved my problem.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>

in my case i started intelliJ as
adminstrator
, then it works
make sure you have tomcat dependency
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>9.0.29</version>
</dependency>

In my case, there is a slight difference between:
Just click Run in the most visible bottom inside IntelliJ and...
Look for the default controller inside src/main/java/com.exampler.yourapplication, right click and press Run there.
The second option just run the project properly.

If below property was added to the allication.properties file, need to remove this.
This property is used to remove the web container.
spring.main.web-application-type=none
In my case I forgot to remove this and once it's removed the issue was fixed

In my case, I need to remove several dependencies first. Then I run maven clean. After that my code just works fine.
