Spring boot 2.2.0 Spring HateOas masalah startup

Saya memindahkan proyek saya dari spring boot 2.1.9 ke 2.2.0. Saat memulai proyek saya menghadapi errorpesan-pesan di bawah ini .

Apa yang bisa menyebabkan, saya tidak menggunakan file hateoassaya pom.xmljuga.

Saya mengalami masalah ini Swagger + HATEOASdalam spring-bootaplikasi saya .

Perbaikan diberikan di bawah ini (edit kelas konfigurasi Swagger Anda):

@Configuration
@EnableSwagger2
public class SwaggerConfiguration {

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

    }
}

Solusi terbaik

Tambahkan kode di bawah ini di kelas 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]  
} 

Bagi saya tautan ini membantu: https://github.com/spring-projects/spring-hateoas/issues/731

Singkatnya saya menambahkan ke dependensi saya:

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

coba versi 2.6.1 ini, saya sudah menyelesaikannya dengan cara ini

<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>

Masalah yang saya hadapi ketika saya menggunakan

<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>

dengan kesombongan 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>

jika Anda melihat ke dependensi musim semi hateoas ada ketergantungan spring-plugin-coredengan versi2.0.0.RELEASE

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

tapi swagger dependensi digunakan spring-plugin-coredengan versi 1.2.0.RELEASE.

pegas-boot memiliki konflik pada pembuatan kacang jadi, Anda perlu menyatukan org.springframework.pluginversi untuk membuat pegas melihatnya, Jika Anda memilih 2.0.0.RELEASEkesombongan bot tidak dapat dikompilasi,

jadi versi 1.2.0.RELEASEakan berfungsi untuk kedua dependensi, seperti

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

Setelah itu Anda memerlukan kelas konfigurasi untuk menginisiasi bean untuk swaggerdan hateoasseperti ini:

@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", "[email protected]");
        return new ApiInfoBuilder()
                .title(""{ApplicationName}"")
                .description("API Description")
                .license("license")
                .version("1.0")
                .contact(contact)
                .licenseUrl("licenseURl")
                .build();
    }
}

Jadi saya benar-benar menginginkan dukungan dari para pembenci dan memiliki masalah yang sama. Ternyata ini terjadi jika sudah

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

dari pada

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

Jika Anda mau Swagger, tetapi dapat berkompromi dengan HATEOAS, maka cukup hapus dependensi HATEOAS dan tambahkan:

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

Mengatasinya, itu terjadi karena integrasi ketika Swagger + HATEOAS digunakan dengan Spring Boot 2.2.4.RELEASE

Saya telah menghapus dependensi ini sebagai solusi dan bekerja:

    <groupId>io.springfox</groupId>
    <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>

tolong beri tahu saya jika berhasil untuk Anda.

Untuk 2.1.3.RELEASEpengguna versi boot Spring , dependensi berikut berfungsi dengan baik untuk 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>

Masalah semacam ini terjadi karena fitur baru dari Hateoas.

Jika Anda ingin menyelesaikan masalah ini, cukup masukkan baris kode berikut dalam file konfigurasi kesombongan Anda.

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

Saya pikir ini akan menyelesaikan masalah Anda karena itu menyelesaikan masalah saya.
