1.引入依赖

 <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.8.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
        </dependency>

2.swagger配置文件

@Configuration
@EnableSwagger2
public class Swagger2Config {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                // 自行修改为自己的包路径
                .apis(RequestHandlerSelectors.basePackage("com.ysk.mybatiscrack"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("swagger-api文档")
                .description("swagger接入教程")
                //服务条款网址
                .termsOfServiceUrl("https://blog.csdn.net/ysk_xh_521")
                .version("1.0")
                .contact(new Contact("Y.S.K", "http://ysk521.cn", "1176971130@qq.com"))
                .build();
    }
}

3.controller注解配置

注意：

在整合Swagger时访问默认的路径：http://localhost:8080/swagger-ui.html，出现404问题，根据查看，发现是相关资源被拦截了，于是配置下就好了

@Configuration
public class WebConfig implements WebMvcConfigurer {

    /**
     * 解决swagger被拦截的问题
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");

        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }

}
