I have recently started my first maven project and after creating a file which uses spring security it doesn't launch anymore due to "ClassNotFoundException: javax.servlet.Filter".
I have been googling for past 2 hours, but I am yet not efficient enough with projects like that to troubleshoot it properly. I was mainly tinkering with the pom.xml file (which is most likely the problem).
pom.xml file:

WebSecurityConfig file which caused the problem:
package com.freshvotes.security;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter
{
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception
{
auth.inMemoryAuthentication()
.withUser("[email protected]")
.password("qwerty")
.roles("USER");

The main problem that you have here is in mixing of framework versions
To fix it you have to remove
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.1.6.RELEASE</version>
</dependency>
And also be sure that you replace all projects imports from javax.x to jakarta.x.
Because from Spring Boot 3.x and Spring Framework 6.x all javax. were replaced with jakarta.x.
Also you will have to migrate Spring Security Configuration part because how I see you are using a lot of deprecated and removed parts of Spring Framework.
More details you can find in next ones resources. Spring Boot 3.0 Migration
