Spring boot 2.2.0 Spring HateOas problema di avvio

Ho spostato il mio progetto da Spring Boot 2.1.9 a 2.2.0. Durante l'avvio del progetto sto affrontando i seguenti errormessaggi.

Cosa potrebbe aver causato, non sto usando neanche hateoasnel mio pom.xmlfile.

Ho avuto questo problema con Swagger + HATEOASnella mia spring-bootdomanda.

La correzione è riportata di seguito (modifica la classe di configurazione di Swagger):

@Configuration
@EnableSwagger2
public class SwaggerConfiguration {

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

    }
}

Soluzione migliore

Aggiungi sotto il codice nella classe SwaggerConfig

@Bean
public LinkDiscoverers discovers() {    
    List<LinkDiscoverer> plugins = new ArrayList<>();
    plugins.add(new CollectionJsonLinkDiscoverer());
    return new LinkDiscoverers(SimplePluginRegistry.create(plugins));[enter image description here][1]  
} 

Per me questo link ha aiutato: https://github.com/spring-projects/spring-hateoas/issues/731

In breve, ho aggiunto alle mie dipendenze:

<dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-core</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>

prova questa versione 2.6.1, ho già risolto in questo modo

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.6.1</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.6.1</version>
</dependency>

Il problema affrontato quando utilizzo

<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>

con spavalderia di springfox

<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>

se dai un'occhiata alle dipendenze degli hateo di primavera, c'è una dipendenza dalla spring-plugin-coreversione2.0.0.RELEASE

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

ma uso di dipendenza spavalderia spring-plugin-corecon la versione 1.2.0.RELEASE.

spring-boot ha conflitti nella creazione del bean, quindi è necessario unificare la org.springframework.pluginversione per farla vedere a Spring, se si sceglie 2.0.0.RELEASEswagger il bot sarà in grado di compilare,

quindi la versione 1.2.0.RELEASEfunzionerà per entrambe le dipendenze, come

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

Dopo di che hai bisogno della classe di configurazione per avviare i bean swaggere in hateoasquesto modo:

@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();
    }
}

Quindi in realtà volevo il supporto di hateoas e avevo lo stesso problema. Si è scoperto che questo succede se lo hai fatto

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

invece di

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-hateoas</artifactId>
</dependency>

Se vuoi Swagger, ma puoi scendere a compromessi HATEOAS, rimuovi la dipendenza HATEOAS e aggiungi:

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

Risolto, stava accadendo a causa dell'integrazione quando Swagger + HATEOAS veniva usato con Spring Boot 2.2.4.

Ho rimosso queste dipendenze come soluzione alternativa e ho funzionato:

<dependency>

    <artifactId>springfox-swagger2</artifactId>
    <version>2.4.0</version>
</dependency>

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.4.0</version>
</dependency>

per favore fatemi sapere se ha funzionato per voi.

Per gli 2.1.3.RELEASEutenti della versione di avvio di Spring , le seguenti dipendenze funzionano bene per hateoas + swagger:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-hateoas</artifactId>
    </dependency>
    <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>

Questo tipo di problema si verifica a causa di una nuova funzionalità di Hateoas.

Se vuoi risolvere questo problema, incorpora la seguente riga di codice nel tuo file di configurazione dello swagger.

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

Penso che questo risolverà il tuo problema poiché ha risolto il mio.
