swagger使用

1.引入依赖，创建配置类

<!--swagger-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <scope>provided </scope>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <scope>provided </scope>
        </dependency>

创建SwaggerConfig配置类

@Configuration
@EnableSwagger2 //swagger注解
public class SwaggerConfig {
    @Bean
    public Docket webApiConfig(){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("webApi")
                .apiInfo(webApiInfo())
                .select()
                .paths(Predicates.not(PathSelectors.regex("/admin/.*")))
                .paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build();
    }


    private ApiInfo webApiInfo(){
        return new ApiInfoBuilder()
                .title("API文档")
                .description("本文档描述了微服务接口定义")
                .version("1.0")
                .contact(new Contact("zhang", "http://atkundi.com", "[email protected]"))
                .build();
    }

}

启动类配置（如果不在一个模块内要进行引入）

@SpringBootApplication
@ComponentScan(basePackages = {"com.kundi"})  //为了扫描到SwaggerConfig
public class CrudApplication {
    public static void main(String[] args) {
        SpringApplication.run(CrudApplication.class,args);
    }
}
