Question

Trying to configure swagger in spring boot 2.3.1.

Gradle Config

repositories {
    mavenCentral()
    maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-rest'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    implementation "io.springfox:springfox-boot-starter:3.0.0-SNAPSHOT"
    compile('io.springfox:springfox-swagger2:3.0.0-SNAPSHOT')
    compile('io.springfox:springfox-swagger-ui:3.0.0-SNAPSHOT')
}

Swagger Config

@Configuration
@EnableSwagger2
public class ApplicationSwaggerConfig {
    @Bean
    public Docket employeeApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build()
                .apiInfo(getApiInfo());
    }

    //create api metadata that goes at the top of the generated page
    private ApiInfo getApiInfo() {
        return new ApiInfoBuilder()
                .title("Employee API")
                .version("1.0")
                .description("API for managing employees.")
                .contact(new Contact("Craig Golightly", "http://globomantics.com", "craig@globomantics.com"))
                .license("Apache License Version 2.0")
                .build();
    }
}

Controller

@RestController
public class TestController {
    @RequestMapping(value = "/HelloWorld", method = RequestMethod.GET)
    public String HelloWorld(){
        return "Hello World";
    }
}

Application

@SpringBootApplication
public class MeroRentalRestApiApplication {
    public static void main(String[] args) {
        SpringApplication.run(MeroRentalRestApiApplication.class, args);
    }
}

There was an unexpected error (type=Not Found, status=404).

Here is the package reference

Same thing with the API-DOC http://localhost:8080/api/v2/api-docs — San Jaisy, Jul 06 '20 at 12:23
Is there a `server.servlet.context-path` property present? If so, try adding the context path to the Swagger urls you're attempting to visit. — Michiel, Jul 06 '20 at 12:59
@Michiel After adding server.servlet.contextPath=/swagger-ui.html. I can see { "_links" : { "profile" : { "href" : "http://localhost:8080/swagger-ui.html/profile" } } } — San Jaisy, Jul 06 '20 at 13:26

Able to solve the problem

Remove the below dependency

compile('io.springfox:springfox-swagger2:3.0.0-SNAPSHOT')
compile('io.springfox:springfox-swagger-ui:3.0.0-SNAPSHOT')

Remove the swagger 2 anotation

@EnableSwagger2

The navigation URL is http://localhost:8080/swagger-ui/index.html

So glad I came across this answer. I was trying to navigate the UI on http://localhost:7000/swagger-ui.html instead of http://localhost:7000/swagger-ui/index.html – Altanai Feb 23 '21 at 22:30
Thanks, in my case I had to add @Profile ("swagger"), to the config. – Manuel Larrota Jul 01 '21 at 16:17
For me it's working without removing @EnableSwagger2. Same result if I remove it too! – Sanal S Apr 19 '23 at 07:20

In spring boot it works by simply adding this, no other dependencies needed:

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

The url is /swagger-ui/

Hello and welcome to StackOverflow! It seems you have given some useful information in your comment. If you would please move that into your answer, then remove the part of your answer which is the same as [Bossit's](https://stackoverflow.com/a/64450250/453435), and mention that your answer builds on Bossit's, then this answer will be much higher quality and won't be closed as a duplicate – Ky - Dec 16 '20 at 19:58

Adding these 2 dependencies in my pom.xml solved the problem

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>
