Swagger not detecting Api built with Spring Data Rest

Question

I'm working on a spring boot application using swagger to generate docs for my API ,I'm using Spring data rest to generate the Api but when I run the app I get the swagger message : No operations defined in spec!

This my Api code :

@Api(tags = "projets")
@RepositoryRestResource(collectionResourceRel = "projets", path = "projets")
public interface IProjectRepository extends JpaRepository<Project, Long> {

}

And this my configuration file :

@Configuration
@EnableSwagger2
public class QfactoryConfiguration {

    @Bean
     public Docket getDocketInstance() {
         return new Docket(DocumentationType.SWAGGER_2) 
                 .apiInfo(new ApiInfoBuilder()
                            .title("Spring Boot project")
                            .description("Spring Boot bootstrap project")
                            .version("0.1")
                            .license("Unlicense")
                            .build())
                  .select()  
                  .apis(RequestHandlerSelectors.basePackage("com.errabi.qfactory.repositories"))             
                  .paths(PathSelectors.any())                          
                  .build();  
     }




}

And this the dependencies that I'm using :

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

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

I'm asking is the Swagger is able to generate docs for Api generated by Spring data rest or I should use a @RestController with annotations @Api,@ApiOperation

I'm using spring boot version : 2.1.3.RELEASE

Answer 1

This did the trick for me, upgrading to the latest snapshot of springfox

<dependencies>
...
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-data-rest</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>
...
</dependencies>

<repositories>
    <repository>
        <id>JFrog</id>
        <name>JFrog Snapshot Repository</name>
        <url>http://oss.jfrog.org/artifactory/oss-snapshot-local/</url>
    </repository>
</repositories>

Then use @EnableSwagger2WebMvc instead of @EnableSwagger2 :

@SpringBootApplication
@EnableSwagger2WebMvc
@Import(SpringDataRestConfiguration.class)
public class MyApplication {

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

}

All thanks to Yann39 .

Answer 2

Based on the discussions on this springfox Github issue looks like you need to amend your config class to include an additional annotation, ie:

@Configuration
@EnableSwagger2
@Import({springfox.documentation.spring.data.rest.configuration.SpringDataRestConfiguration.class})

I can't test it as I only use swagger for Rest controllers at present but hope this helps.

Answer 3

Did you get to the bottom of this using the latest version of Springfox 3.0.0-SNAPSHOT? I can't see the Spring Data Rest endpoints that are generated in Swagger UI using the latest versions of both Springfox and Spring Boot 2.

Answer 4

pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.2.RELEASE</version>
    <relativePath />
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <swagger>3.0.0-SNAPSHOT</swagger>
</properties>

<dependencies>
<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>${swagger}</version>
    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>${swagger}</version>
    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-data-rest</artifactId>
        <version>${swagger}</version>
    </dependency>

</dependencies>

application.yaml

spring:
    data:
        rest: 
            base-path: /v1

java config

@Configuration
@EnableSwagger2WebMvc
@Import(SpringDataRestConfiguration.class)
public class SwaggerConfig 

Answer 5

尝试RequestHandlerSelectors.any()而不是RequestHandlerSelectors.basePackage("") 。

Answer 6

Verify your package & add

@Configuration
@EnableSwagger2

to the spring boot configuration file

   @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).select()
                .apis(RequestHandlerSelectors.basePackage("your.package.name")).paths(PathSelectors.any()).build()
                .apiInfo(apiEndPointInfo());
    }

only those dependencies are required

<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>

your final config file should looks like this

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@Configuration
@EnableSwagger2
public class TestappApplication implements WebMvcConfigurer {

    private static final String PREFIX = "/WEB-INF/views/";
    private static final String SUFFIX = ".jsp";

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

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp(PREFIX, SUFFIX);

    }

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).select()
                .apis(RequestHandlerSelectors.basePackage("your.package.scan.to.swagger.annotations")).paths(PathSelectors.any()).build()
                .apiInfo(apiEndPointInfo());
    }

    public ApiInfo apiEndPointInfo() {
        return new ApiInfoBuilder().title("Spring Boot Rest API").description("user Management API")
                .contact(new Contact("zouhair kasmi", "website.com/", "myemail@gmail.com"))
                .license("Apache 2.0").licenseUrl("http://www.apache.org/licenses/LICENSE-2.0.html")
                .version("0.0.1-SNAPSHOT").build();

    }
