配置：

package com.aiyuesheng.config;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                // api扫包
                .apis(RequestHandlerSelectors.basePackage("com.aiyuesheng.api")).paths(PathSelectors.any()).build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder().title("微服务电商系统").description("微服务电商系统接口文档")
                .termsOfServiceUrl("http://www.aiyuesheng.com")
                // .contact(contact)
                .version("1.0").build();
    }

}

service 接口：

@Api("Swagger Sample")
@RestController
public class SwaggerService {

    @ApiOperation("swagger 注解")
    @PostMapping("/swaggerIndex")
    public String swaggerIndex() {
        System.out.println("swaggerIndex");
        return "swaggerIndex";
    }

}

启动类：

@SpringBootApplication
public class SwaggerApp {
    public static void main(String[] args) {
        SpringApplication.run(SwaggerApp.class, args);
    }

}
