springboot2.6.7集成springfox3.0.0的示例代码

springboot2.6.7集成springfox3.0.0 

1. pom配置

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0</version>
</dependency>

2. 增加swagger自动配置类

import org.springframework.context.annotation.Configuration;
import springfox.documentation.oas.annotations.EnableOpenApi;
@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.OAS_30)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
                .build();
    }
	private SecurityScheme apiKey() {
        return new ApiKey("JWT", "Authorization", "header");
    }
}

此时尝试启动应用会提示一下错误：

3. 配置修改

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

4. 自动配置类增加以下内容

@Bean
public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(
        WebEndpointsSupplier webEndpointsSupplier,
        ServletEndpointsSupplier servletEndpointsSupplier,
        ControllerEndpointsSupplier controllerEndpointsSupplier,
        EndpointMediaTypes endpointMediaTypes,
        CorsEndpointProperties corsProperties,
        WebEndpointProperties webEndpointProperties,
        Environment environment) {
    List<ExposableEndpoint<?>> allEndpoints = new ArrayList();
    Collection<ExposableWebEndpoint> webEndpoints = webEndpointsSupplier.getEndpoints();
    allEndpoints.addAll(webEndpoints);
    allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
    allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
    String basePath = webEndpointProperties.getBasePath();
    EndpointMapping endpointMapping = new EndpointMapping(basePath);
    boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(
            webEndpointProperties, environment, basePath);
    return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints,
            endpointMediaTypes, corsProperties.toCorsConfiguration(),
            new EndpointLinksResolver(allEndpoints, basePath),
            shouldRegisterLinksMapping, null);
}
private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties,
                                           Environment environment, String basePath) {
    return webEndpointProperties.getDiscovery().isEnabled() &&
            (StringUtils.hasText(basePath) ||
                    ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
}
