O swagger do Springfox não funciona na bota de mola 2.2.0

Quero atualizar o boot da primavera v2.1.9 para o 2.2.0. Mas após a atualização, estou recebendo algumas exceções, que dizem que o spring fox está usando uma versão mais antiga do spring-plugin-core.

Existe alguma solução alternativa para isso ou preciso desistir do plugin springfox?

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    springfox.documentation.spring.web.plugins.DocumentationPluginsManager.createContextBuilder(DocumentationPluginsManager.java:152)

The following method did not exist:

    org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;Lorg/springframework/plugin/core/Plugin;)Lorg/springframework/plugin/core/Plugin;

The method's class, org.springframework.plugin.core.PluginRegistry, is available from the following locations:

    jar:file:/C:/Users/regosa/.m2/repository/org/springframework/plugin/spring-plugin-core/2.0.0.RELEASE/spring-plugin-core-2.0.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

It was loaded from the following location:

    file:/C:/Users/regosa/.m2/repository/org/springframework/plugin/spring-plugin-core/2.0.0.RELEASE/spring-plugin-core-2.0.0.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.plugin.core.PluginRegistry

Você pode usar SpringFox 3.0.0-SNAPSHOTcomSpring Boot 2.2.X

• Como é uma versão SNAPSHOT, ela não é publicada no repositório oficial do maven e precisa ser extraída dos jcenter-snapshots
• @EnableSwagger2 é removido e alterado para @EnableSwagger2WebMvc e@EnableSwagger2WebFlux

Nota: Parece que nãoSpringFox está morto .

Aparentemente, como SpringFoxfoi abandonado e sua última versão não é mais compatível com o Spring Boot 2.2.X, você terá que procurar alternativas (consulte o problema relatado no Github aqui ).

Uma opção possível é usar OpenAPI docs. Para isso, você precisa remover as SpringFoxdependências e adicioná-las:

        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-ui</artifactId>
            <version>1.2.15</version>
        </dependency>
         <dependency>
              <groupId>org.springdoc</groupId>
              <artifactId>springdoc-openapi-webmvc-core</artifactId>
              <version>1.2.15</version>
        </dependency>

Além disso, você precisará remover a Swaggerclasse de configuração e fornecer o seguinte:

    @Configuration
    public class OpenApiConfig {

    @Bean
    public OpenAPI customOpenAPI() {
        return new OpenAPI()
                .components(new Components())
                .info(new Info().title("Contact Application API").description(
                        "This is a sample Spring Boot RESTful service using springdoc-openapi and OpenAPI 3."));
    }
}

No meu caso, tudo parece funcionar com exceção dos repositórios JPA Rest que não estão sendo expostos. Atualizarei esta resposta com uma correção, se encontrar uma.

Estes são alguns dos links que eu estava verificando para corrigir isso:

• Documentando APIs REST de Inicialização Spring com API Aberta
• Spring Boot OpenAPI no GitHub

Fixo!!!

O problema existe porque as bibliotecas spring fox dependem internamente do spring-plugin-core: 1.2.0, mas na verdade requer o spring-plugin-core: 2.0.0. Essa correção de dependência parece estar ausente na versão SNAPSHOT das bibliotecas swagger para suportar o fluxo da Web.

Nós só precisa dependências Maven corretas como dado abaixo e nenhuma alteração de código é necessária:

• Correção de dependências do Maven POM

</dependency>

• Configuração do Swagger: (O mesmo de antes apenas para referência)

    @Configuration
    @EnableSwagger2WebFlux
    public class SwaggerConfiguration {

        @Bean
        public Docket api(final TypeResolver typeResolver) {
            return new Docket(DocumentationType.SWAGGER_2)
                    .select()
                    .apis(RequestHandlerSelectors.any())
                    .paths(PathSelectors.any())
                    .build();
        }
    }

Remova a dependência do ódio, mas adicione apenas arrogância. Funciona

// Usando apenas o swagger a partir de agora, já que hateos não é atualizada, a correção para o grupo de compilação Spring 2.1.X e superior: 'io.springfox', nome: 'springfox-swagger-ui', versão: '2.9.2' grupo de compilação: 'io.springfox', nome: 'springfox-swagger2', versão: '2.9.2'

Estou usando o spring-boot 2.2.2.RELEASE e não houve nenhum problema com o spring-core e o swagger . Abaixo da importação estava o culpado

spring-boot-starter-data-rest
