SpringBoot集成Swagger

1.导入相关依赖

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

2.Swagger配置文件config

@Configuration//将config加入到springboot里
@EnableSwagger2//开启Swagger2（Swagger2是新版本）
public class Swagger2 {
}

3.测试
http://localhost:8080/swagger-ui.html

4.配置Swagger

public class Swagger2 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(this.apiInfo())
                .select()//选择哪些路径和api会生成document
                .apis(RequestHandlerSelectors.basePackage("com.synda.ynmzgx"))//对指定包进行监控
                .paths(PathSelectors.any())//对所有路径进行监控
                .build()
                .globalOperationParameters(setHeaderToken());
    }
	//配置swagger信息=apiInfo
	private ApiInfo apiInfo(){
	//作者信息
	Contact contact = new Contact( name: "xx"，url: "https://blog.youkuaiyun.com/AllenLFC"，email: "xxx@qq.com" );
	return new ApiInfo(
	title: "SwaggerAPI文档" ,
	description:"即使再小的帆也能远航"，
	version: "v1.0" ,
	termsOfServiceUrl: "https://blog.youkuaiyun.com/AllenLFC",
	contact,
	license: "Apache 2.0",
	licenseUrl: "http://www.apache.org/licenses/LICENSE-2.0",
	new ArrayList()
);
}

5.使用相应注解

 * @create 2018-10-23 11:07
 */
​
@RestController

​
 @Autowired

上线前注意关闭Swagger，不然会降低效率
