Why HATEOAS starts creating issue for spring-boot version >= 2.2.x during startup with Swagger 2.x?

Question

I moved my project from spring-boot 2.1.9 to 2.2.0.

While starting the project, I am facing the below error messages.

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.plugin.core.PluginRegistry<org.springframework.hateoas.client.LinkDiscoverer, org.springframework.http.MediaType>' available: expected single matching bean but found 17: modelBuilderPluginRegistry,modelPropertyBuilderPluginRegistry,typeNameProviderPluginRegistry,syntheticModelProviderPluginRegistry,documentationPluginRegistry,apiListingBuilderPluginRegistry,operationBuilderPluginRegistry,parameterBuilderPluginRegistry,expandedParameterBuilderPluginRegistry,resourceGroupingStrategyRegistry,operationModelsProviderPluginRegistry,defaultsProviderPluginRegistry,pathDecoratorRegistry,apiListingScannerPluginRegistry,relProviderPluginRegistry,linkDiscovererRegistry,entityLinksPluginRegistry

Description:

Use `mvn dependency:tree` and check if something else is pulling in the `Hateoas` dependency. IRC If you use Spring Data REST that has a dependency on Spring Hateoas. — M. Deinum, Oct 17 '19 at 13:16
I have this same issue on the upgrade. I do know where the dependency is coming from but I haven't been able to find a solution. — mkeathley, Oct 18 '19 at 01:20

I had this issue with Swagger + HATEOAS in my spring-boot application.

The fix is given below (edit your Swagger configuration class):

@Configuration
@EnableSwagger2
public class SwaggerConfiguration {

    @Bean
    public LinkDiscoverers discoverers() {
        List<LinkDiscoverer> plugins = new ArrayList<>();
        plugins.add(new CollectionJsonLinkDiscoverer());
        return new LinkDiscoverers(SimplePluginRegistry.create(plugins));

    }
}

This doesn't seem to work for me as `_links` is turned into `links` and `_embedded` is turned into `content` in the response, therefore most of my mvcMock tests checking the `_links` are failing and the API is different from what's provided out of the box with spring-boot-starter-hateos – Kerruba Mar 18 '20 at 09:07
I had this happen as well. You need to enable Hal+json – dukevin Mar 19 '20 at 03:31
lemon could you elaborate a bit please? I've tried to use of the `HalLinkDiscoverer` class instead of the `CollectionJsonLinkDiscoverer` didn't do the trick and still my tests fail because links are rendered as `links` and not `_links`, as well as content is rendered as `content` and not the expected `_embedded` – Kerruba Mar 19 '20 at 09:01
The way I did it in my configuration java file was `@EnableHypermediaSupport(type=EnableHypermediaSupport.HypermediaType.HAL)` you must include `org.springframework.hateoas.config.EnableHypermediaSupport`. Not sure if it matters but I have as a dependency: spring-boot-starter-hateoas – dukevin Mar 19 '20 at 16:45
@lemon Nice answer !! This works for spring-boot 2.3.0 + hateoas + Swagger 2.9.2 – Anish B. May 03 '20 at 07:41

@Kerruba were you able to solve the issue? I'm also facing the same issue. – Pawan Kumar Dec 16 '20 at 08:42
@lemon your response fixed my issue but after adding ``EnableHypermediaSupport(type=EnableHypermediaSupport.HypermediaType.HAL)`` same issue started appearing again. I tried this because in reponse I was getting ``links`` instead if ``_links`` – Pawan Kumar Dec 16 '20 at 08:45
`SimplePluginRegistry.create()` seems to be deprecated. Is there an alternative to this? – Arun Gowda Jun 22 '21 at 07:04

In a nutshell i added to my dependencies:

Thanks! This worked for me. Also, in this tutorial, there is a reference to that dependency: https://www.baeldung.com/spring-hateoas-tutorial – neojal Dec 03 '19 at 17:35
That helped me a lot. However what I do not understand is that I was supposed to get this dependency from `spring-boot-starter-hateoas` but for some reason maven was not linking the transitive dependency. Suddenly after few hours I got this transitive dependency. – scarface Mar 16 '22 at 08:53

This kind of issue is occurring due to a new feature of Hateoas.

If you want to solve this problem , just embed the following line of codes in your swagger configuration file.

@Primary
@Bean
public LinkDiscoverers discoverers() {
    List<LinkDiscoverer> plugins = new ArrayList<>();
    plugins.add(new CollectionJsonLinkDiscoverer());
    return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
}

I think this is gonna solve your problem as it solved mine.

    Use following 2 dependency to resolve Swagger and Hateoas dependency conflict.
    
    If Spring Boot version is >= 2.2.0 the use io.springfox version 3.0.0
    
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>3.0.0</version>
    </dependency>
    
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>3.0.0</version>
    </dependency>

After using version 3.0.0 swagger-ui will not be working so use following dependency and user /swagger-ui/ instead /swagger-ui.html

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

To solve my issue I had first to do what is described by @lemon and then upgrade Springfox dependencies to 3.0.0 and add the starter. Without this, I had multiple occurence of beans available and Spring Boot was not able to choose. — bryce, Dec 09 '20 at 11:41

The issue faced with me when i using

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-dependencies</artifactId>
   <version>2.2.6.RELEASE</version>
   <type>pom</type>
   <scope>import</scope>
</dependency>
.....
.....
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-hateoas</artifactId>
</dependency>

with springfox swagger

<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>

if you take a look into spring hateoas dependencies there is a dependency on spring-plugin-core with version 2.0.0.RELEASE

<dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-core</artifactId>
    <version>${spring-plugin.version}</version>
</dependency>

but swagger dependency use spring-plugin-core with version 1.2.0.RELEASE.

spring-boot have conflict on bean creation so, you need to unify the org.springframework.plugin version to make spring see it, If you choose 2.0.0.RELEASE swagger will bot be able to compile,

so version 1.2.0.RELEASE will be work for both dependencies, like

 <dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-core</artifactId>
    <version>1.2.0.RELEASE</version>
</dependency>

After that you need configuration class to initiate beans for swagger and hateoas like this:


@EnableSwagger2
@Configuration
public class SwaggerConfiguration {

    @Primary
    @Bean
    public LinkDiscoverers discoverers() {
        List<LinkDiscoverer> plugins = new ArrayList<>();
        plugins.add(new CollectionJsonLinkDiscoverer());
        return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
    }

    @Bean
    public Docket postsApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("{ApplicationName}")
                .apiInfo(buildApiInfo())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.regex("/.*"))
                .build();
    }

    private ApiInfo buildApiInfo() {
        Contact contact = new Contact("CompanyName", "https://company-domain.com", "mail@company.com");
        return new ApiInfoBuilder()
                .title(""{ApplicationName}"")
                .description("API Description")
                .license("license")
                .version("1.0")
                .contact(contact)
                .licenseUrl("licenseURl")
                .build();
    }
}

Thanks! This solution worked for me and I'm using `@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)` to have `"_links"` with underscores. I updated swagger version to `2.9.2`. However, I didn't need the `discovers()` method and it still works! — JsonMraz, May 24 '20 at 09:54

I am using springdoc-openapi and after having encountered this problem similar to the one mentioned here:

Description:

Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 3 were found:
    - relProviderPluginRegistry: defined by method 'relProviderPluginRegistry' in class path resource [org/springframework/hateoas/config/HateoasConfiguration.class]
    - linkDiscovererRegistry: defined in null
    - entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry' in class path resource [org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

I just add this dependency in my pom file

<dependency>
    <groupId>org.springframework.hateoas</groupId>
    <artifactId>spring-hateoas</artifactId>
    <version>1.1.1.RELEASE</version>
</dependency>

As Alexander Weiß has already answered, the spring-plugin-core dependency is resolved with the wrong version 1.2.0.RELEASE.

In order to force usage of the correct 2.0.0.RELEASE, you have to EITHER exclude the wrong transitive dependency and explicitly specify the correct one, OR to pin (!) that dependency version in your pom.xml. This is done in the <dependenciesManagement> block, not in the <dependencies> block. Pinning example for Springfox 3.0.0:

<properties>
    <spring-plugin-core.version>2.0.0.RELEASE</spring-plugin-core.version>
    <springfox.version>3.0.0</springfox.version>
</properties>

<dependencyManagement>
  <dependencies>
    <!-- API Documentation -->
    <!-- Fix wrong resolved `spring-plugin-core` dependency version for springfox -->
    <dependency>
      <groupId>org.springframework.plugin</groupId>
      <artifactId>spring-plugin-core</artifactId>
      <version>${spring-plugin-core.version}</version>
    </dependency>
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-boot-starter</artifactId>
      <version>${springfox.version}</version>
    </dependency>
  </dependencies>
</dependencyManagement>

So I actually wanted hateoas support and had the same issue. Turned out this happens if you have

instead of

    }
}

From where are you getting the SwaggerConfigProperties ? – rajadilipkolli Apr 21 '20 at 12:26 — rajadilipkolli, Apr 21 '20 at 12:26

If you want Swagger, but can compromise with HATEOAS, then just remove the HATEOAS dependency and add:

compile group: 'io.springfox', name: 'springfox-swagger-ui', version:'2.9.2'  
compile group: 'io.springfox', name: 'springfox-swagger2', version: '2.9.2'

Why HATEOAS starts creating issue for spring-boot version >= 2.2.x during startup with Swagger 2.x?
