Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Forbidden, status=403).

By default, spring-security will protect each and every end-point - So, for /error you need to manually configure like the following -
#EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
public void configure(HttpSecurity auth) {
auth.csrf().disable()
.authorizeRequests()
.antMatchers("/error/**").permitAll() // permit-all for /error page
.anyRequest().authenticated();
}
}

For future reference:
In Spring Boot 3.0 / Spring Security 6.0 http.antMatcher() is not longer available and was replaced with http.securityMatcher().
So Subham's answer would look like that:
#Configuration
public class SecurityConfiguration {
#Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.authorizeHttpRequests((authz) -> authz.anyRequest().permitAll())
.csrf().disable()
.securityMatcher("/error/**")
.httpBasic(withDefaults());
return http.build();
}
}

You are trying to run the application on port 80.

Either run it as root (not recommended) or use another port.

Failed to start bean 'webServerStartStop'; Unable to start embedded Tomcat server - spring-boot-starter-web

Spring application using Maven including only Spring Web dependency gives "Unable to start embedded Tomcat serve" error.
The same project runs on other computers like expected.
Spring Boot Version: 2.4.3
Package Type: JAR
Java Version: 11
No additional code added from the starter project except to print to the console for testing.
Application runs and prints to the console like expected when tomcat is excluded int the pom.xml.
Tested multiple ports.
Tested JDK 8 and 11.

There was control software installed for the individuals Network interface controller (NIC) that allowed both ethernet and wifi to be used simultaneously. This was installed to supposedly improve gaming experience, but did not play nicely with tomcat in Spring. Once disabled the application was able to run as expected.
Edit:
A similar error occurs if your address or port is incorrect / already used. This fixes the error in most situations, but a driver like the one mentioned above may cause the error.

It got fixed for me after changing server.port to 8080 from 80.

I was trying to run spring boot on my local network and that error occurred.
The problem was a wrongly specified IP address property inside my application-dev.yml file.
server:
address: 192.168.0.107 // it needed to be 192.168.0.104
port: 8080
You can always check your IPv4 Address by running ipconfig.

Disable the Gamingservices service or go to the task manager and end the task of gamingservices and run again the application. or restart the computer.

Intellij Community Edition showing this error on schema.sql file as can see on image that I droped here

When I run the application this shutdown and don't allow me enter on H2 database on localhost h2 URL.
Is anyone else having this same problem?

How to check for another running project on Eclipse?

I am using eclipse IDE to run my spring boot project(the backend part) which uses the port 8080 on localhost. When i try to run my program it shuts down the program saying port 8080 was already in use. There isn't any other application that is using the port 8080 and there is no other console window because of which i cannot shut down the currently running application that is using port 8080. PFB the logs from the console window:

Description:
Web server failed to start. Port 8080 was already in use.
Action:
Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.

This can be because you might gave run the project first (so it occupied the port) and now you are trying to run it again without closing the last one.Use this Option

The error message is not ambiguous, and that's not something that will occur "erroneously" (saying something is using the port when it's not actually in use). The port doesn't have to be used by something you started from Eclipse. There is no question that something is already listening on that port. You just have to figure out what it is. Alternatively, you could set up your application to run on a different port.
