spring为什么我的大摇大摆不能用springboot在java中工作？

Question

请建议如何解决此问题。我被困在这里了

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {

        return new Docket(DocumentationType.SWAGGER_2);

    }
}

错误消息如下

• ****************************应用程序无法启动

  说明：

  中方法链接发现者的参数0 组织。springframework。哈提奥斯。配置。HATEOASCO配置需要一个 单个bean，但找到17个：

  • modelBuilderPluginRegistry:在null中定义
  • modelPropertyBuilderPluginRegistry:在null中定义
  • typeNameProviderPluginRegistry:在null中定义
  • syntheticModelProviderPluginRegistry:在null中定义
  • documentationPluginRegistry:在null中定义

  • LinkDiscoveryrRegistry:在null中定义
  • entityLinksPluginRegistry:由类路径资源中的方法“entityLinksPluginRegistry”定义 [org/springframework/hateoas/config/webmvcentitylinkscoconfiguration.class]

  行动：

  考虑将bean中的一个标记为“初级”，更新消费者。 接受多个bean，或使用@Qualifier标识bean 应该被消耗掉的

希望这会有所帮助

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;


@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket siteOfficeApi() {
        return new Docket(DocumentationType.SWAGGER_2)
               .select()
               .apis(RequestHandlerSelectors
                    .basePackage("Basepackage"))
               .paths(PathSelectors.any())
               .build()
               .apiInfo(metaData());
    }

    private ApiInfo metaData() {
        ApiInfo apiInfo = new ApiInfo(
            "Title",
            "Description",
            "Version",
            "Terms of service",
            "Contact Name",
            "License",
            "Licence URL");
        return apiInfo;
    }
}

使用这两个maven依赖项

    <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>

Answer 2

我猜您使用的是Swagger 2.9.2和SpringBoot 2.2。x、 它有一个兼容的open issue

Answer 3

请尝试下面的配置类来修复此问题

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {

        return new Docket(DocumentationType.SWAGGER_2).select()
    .apis(RequestHandlerSelectors.basePackage("package Name")).paths(PathSelectors.any())
                .build();

    }
}

Answer 4

确保将以下依赖项添加到pom中

<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>**[version here]**</version>
        <exclusions>
            <exclusion>
                <groupId>org.mapstruct</groupId>
                <artifactId>mapstruct-jdk8</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>**[version here]**</version>
    </dependency>

如果不起作用，请提供更多信息

Answer 5

我做了如下的应用程序

@SpringBootApplication
@EnableWebSecurity
public class BootApplication extends WebSecurityConfigurerAdapter implements 
WebMvcConfigurer {

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/swagger-ui.html**")
            .addResourceLocations("classpath:/META-INF/resources/swagger-ui.html");
    registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}

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

@Bean
public BootApplicationProperties bootApplicationProperties() {
    return new BootApplicationProperties();
}

/**
 * main for running the app.
 *
 * @param args main arguments
 */
public static void main(String[] args) {
    SpringApplication.run(BootApplication.class, args);
}

}

然后取消测试配置文件，以避免在测试过程中失败，并按如下所示设置招摇过市配置

    @Profile({"local","dev", "deva","devb","devc","staging","prod", "!test"})
    @EnableSwagger2
    @Configuration
    public class SwaggerConfig /*extends WebMvcConfigurationSupport*/ {

        public Docket productApi() {
            return new Docket(DocumentationType.SWAGGER_2).select()
                    .apis(RequestHandlerSelectors.basePackage("com.wellsfargo.fcp.uae.goaml.controller"))
                    .paths(PathSelectors.any())
                    .build();
        }

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



        private ApiInfo metaData() {
            /*ApiInfo apiInfo = new ApiInfoBuilder("Spring Boot REST API", "Spring Boot REST API for Online Store", "1.0",
                    "Terms of service", new Contact("Hatice Sigirci", null, "hatice.sigirci@hotmail.com"),
                    "Apache License Version 2.0", "https://www.apache.org/licenses/LICENSE-2.0", null);
            return apiInfo;*/
            return new ApiInfoBuilder().title("Boot REST API")
                    .description("Boot REST API reference ")
                    .termsOfServiceUrl("http://tchelpcom")
                    .contact("http://tchelp com").license("©  All rights reserved")
                    .licenseUrl("http://tchelp.com").version("1.0").build();
        }

    }


          

Answer 6

您可以通过添加以下bean来更改配置类

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

配置类如下所示：

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2);
    }

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