Swagger Spring API - xmlModelPlugin Error

2022-09-03 09:06:16

我试图用下面的代码来使用swagger:......

@EnableSwagger2
@PropertySource("classpath:swagger.properties")
@ComponentScan(basePackageClasses = PersonController.class)
@Configuration
public class SwaggerConfig {

    private static final String SWAGGER_API_VERSION = "1.0";
    private static final String LICENSE_TEXT = "License";
    private static final String title = "Products REST API";
    private static final String description = "RESTful API for Products";

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(title)
                .description(description)
                .license(LICENSE_TEXT)
                .version(SWAGGER_API_VERSION)
                .build();
    }

    @Bean
    public Docket productsApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .pathMapping("/")
                .select()
                .paths(PathSelectors.regex("/api.*"))
                .build();
    }
}

但有以下错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'xmlModelPlugin': Failed to introspect bean class [springfox.documentation.schema.XmlModelPlugin] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlType

答案 1

在我的情况下,它是解决方案:

 <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>

答案 2

对我来说,解决方案只是从Java 11回退到Java 8。我甚至不需要将依赖项添加到javax.xml.bind中
