How I run Swagger in SpringBoot 3.2.0?

Question

When I am using** springboot 3.2.0 with swagger 2.9.2 it does not work**. How i fix it without downgrade springboot 3.2.0 verrsion?

this is my swagger config

package com.lifepill.possystem.config;

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;

@Configuration
public class SwaggerConfig {
    @Bean
    public Docket SwaggerApi(){
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build();
    }
}

When i try with springboot 2.7.17 version swagger is working. But 3.2.0 verion doesn't work. I try Spring Cores it also..

Answer 1

just found the solution:

I had this dependency before migrating to 3.2.0:

    <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-ui</artifactId>
        <version>1.6.14</version>
    </dependency>

I had to replace it to :

    <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
        <version>2.3.0</version>
    </dependency>

And now it is working on my side. I took the latest version available here: https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi-starter-webmvc-ui

On your side you're still using springfox, so I do believe you can completly replace your 2 dependencies by the springdoc openapi one :)

(FYI on my side I don't have anymore the SwaggerConfig java class, not sure if this one is needed)
