編寫配置文件

package com.example.vuespringboot.config;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

public class Swagger3Config {
    @Configuration
    @EnableOpenApi
    public static class Swagger2Config{
        @Bean
        public Docket createRestApi() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("com.example.vuespringboot.controller"))
                    .paths(PathSelectors.any())
                    .build();
        }

        private ApiInfo apiInfo() {
            return new ApiInfoBuilder()
                    .title("項目接口文檔html")
                    .version("1.0")
                    .build();
        }
    }

}
