Spring App is not running from Intellij with Tomcat Server

If I run my spring app from Intellij with Tomcat Server it gives me:
HTTP Status 404 – Not Found
Type Status Report
Message The requested resource [/] is not available
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.52
But If I put my app.war in tomcat/webapps/ as ROOT.war it works perfectly.
I have problems only when try to run from Intellij
This is the configuration:
This is the deployment:
And this is the output:
C:\apache-tomcat-9.0.52\bin\catalina.bat run

I want to run my app from the root: localhost:8080/.
Why I receive 404 - Not Found from Tomcat? And how to fix it?
If you need more details please tell me.

P.S.: I think something is not deployed right. Because after deploy, in console don't appears that big SPRING logo and logs about initializing. Or this is not necessarily?

I found the solution for my problem.
My problem was solved by removing everything from Run/Debug Configuration -> Before Launch
Also instead of what was there I added maven clean install command.

NetBeans can not start Tomcat on mac

I am trying to run Tomcat using NetBeans on Mac. When I execute startup.sh in bin folder and then access http://localhost:8080 everything looks great. Then I tried running my JAVA project in NetBeans, but it said that port 8080 is already in use. So I found which process is running on this port using lsof -i :8080 and killed it (or executed shutdown.sh in bin folder, it is the same).
Then I tried to run my project in NetBeans and after over 3 minutes of waiting it says this
.../WebApplication/nbproject/build-impl.xml:1045: Deployment error: Starting of Tomcat failed.

Can you guys help me? I do not know what to solve this several days...

From the Comments:
In Netbeans, go to Tools -> Options -> and select No Proxy (if you're not behind the proxy server) - Shashanth
To resume this for both Mac OS and Windows:
on Mac: Go to Netbreans Preferences, and there choose "No Proxy".
on Windows, Go to Tools, then Options, and there choose "No Proxy".
I'm answering this so other users with the same problem can easily determine the answer that was provided.

You can try installing XAMPP for mac it explicitly runs the server for you to run your application or you can try with Apache Tomee server.
XAMPP: https://www.apachefriends.org/download.html
TOMEE: http://tomee.apache.org/downloads.html

I had the same problem.
What my problem was I was using wrong jdk version for netbeans. For example, I was using jdk version java-1.8 with netbeans 12. I changed the JDK version to the latest and tried running tomcat again and it started working.
It took me a week to figure this thing out. All the other options didn't work for me.

IntelliJ IDEA: Tomcat 8.5.13 and 9.0.0.M19 — Error during artifact deployment. See server log for details

I can't understand what happened. There was no problem 2 days ago and now I can't deploy my applications. Any of it. The only thing I've done regarding network was plugging my laptop in other socket in the house using ethernet wire, nothing else. I tried almost every solution I found here and nothing helped.

Disconnected from server
When i attempt to connect to "localhost:8080" i get a message about connection being REJECTED and "Disconnected from server" message in logs.
There is nothing useful in the logs (no warnings/errors).
This issue is in EVERY of my JEE applications.
As I said a tried many solutions from here EXCEPT the one with changing the value of %JAVA_OPTS% env var because I've got no 'setenv.bat' file anywhere in Tomcat directory and in Catalina.bat this variable seems to be set properly.
I'm quite new to this kind of technology and I am a little afraid to start tweaking around in stuff I don't know.
What could be causing this issue? What are the possible solutions?

There appears to a be a deployment issue with the most recent Tomcat versions from IntelliJ IDEA. We have an open bug for that with the patched files attached that you can use to workaround the problem:
IDEA-171174 Tomcat 9.0.0.M19: failed to deploy simple WAR artifact
You can find the patched jar of IntelliJ IDEA Tomcat plug-in, replace <IDEA_HOME>/plugins/Tomcat/lib/tomcatIntegration.jar with it.
The original issue is caused by this Tomcat bug:
Bug 60949 - unable to deploy/undeploy war file using the manager
This bug is resolved in the following Tomcat versions:
8.5.14 and later
9.0.0.M20 and later
It's recommended to either wait for/install the fixed Tomcat versions or to revert back to the versions which are not affected by the bug (5.8.12 and 9.0.0.M18), since the workaround for IntelliJ IDEA uses some dirty hacks to make it work with Tomcat 5.8.13 and 9.0.0.M19 which are affected by Bug 60949 (broken JMX).

I was using Spring application and deploying with Tomcat. What was solved my problem is to put this annotation to SpringApplication class which app starts from that class.
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })

The issue got fixed for me by downgrading IntelliJ to 2019.2.4

Intellij warning no artifacts configured

I have two classes
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
package com.example;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class SampleController {
#RequestMapping("/")
public String index() {
return "Greetings from Spring Boot!";
}
}
I want to make a springboot application that uses maven and tomcat. I want to see output in localhost page.
I use 8282 port, when i click run, it opens that page but it is empty.
So i created a war artifact. Web applicatin exploded but this time it says can not create artifact and it doesnot open that web page.
Why does it show an empty page? I was seeing the output before integrating tomcat.
This is output
