springboot 添加swagger

在pom.xml文件添加

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

            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

添加swagger配置类

/**

@Configuration
@EnableSwagger2

    @Bean
    public Docket createRestApi() {
        //在配置好的配置类中增加此段代码即可
        ParameterBuilder ticketPar = new ParameterBuilder();
        List<Parameter> pars = new ArrayList<Parameter>();
                //名称
        ticketPar.name("ACCESS_TOKEN")
                //表示描述
                .description("登录校验")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                //是否必填
                .required(false).
                //默认值
                defaultValue("")
                .build();
        pars.add(ticketPar.build());
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                // 只扫描带api注解的ID
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                //这里采用包扫描的方式来确定要显示的接口
//                .apis(RequestHandlerSelectors.basePackage("com.cn.controller"))
                .paths(PathSelectors.any())
                .build()
                .globalOperationParameters(pars)
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API")
                .description("接口文档")
                .termsOfServiceUrl("")
                .version("1.00")
                .build();
    }
}

在启动类上添加包扫描
