springboot整合swagger2

1.所需依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>

2.swagger2配置类

代码中红色部门是控制器的包

@Configuration
@EnableSwagger2
public class SwaggerConfig {


    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller")).paths(PathSelectors.any())
                .build().globalOperationParameters(setHeaderToken());

    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder().title("action-swagger").description("swagger实战").termsOfServiceUrl("")
                .version("1.0").build();
    }

    /**
     * @Description: 设置swagger文档中全局参数
     * @param
     */
    private List<Parameter> setHeaderToken() {
        List<Parameter> pars = new ArrayList<>();
        ParameterBuilder userId = new ParameterBuilder();
        userId.name("token").description("用户TOKEN").modelRef(new ModelRef("string")).parameterType("header")
                .required(true).build();
        pars.add(userId.build());
        return pars;
    }
}
