Error with Swagger Integration in Spring Boot: java.lang.TypeNotPresentException: Type javax.servlet.http.HttpServletRequest not present

I'm trying to implement API documentation using Swagger in my Spring Boot application, but I keep encountering this stack trace when attempting to run the application:

Can someone elaborate, why this might be happening why the latest core library is referring to old javax HttpServletRequest??

I have already gone through relevant questions, But they don't answer my query to the point and they talk about Swagger and SpringFox dependency fixes!!

I have listed starting from POm file, the swagger config class and the full stack trace below,any help will be highly appreciated

I also have this class set up for Swagger configuration:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.restapi.rest_demo"))
                .paths(PathSelectors.any())
                .build();
    }
}

Solution

The error was due to a compatibility issue between the versions of Spring Boot(im using 3.4.1) and Springfox.

so I had to remove the Springfox dependency:

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

then replace with the SpringDoc dependency:

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
    <version>2.6.0</version>
 </dependency>

After making these changes,I had to rebuild my project and then run it again. The Swagger UI should be available at http://localhost:8080/swagger-ui.html (adjust the port if necessary).
