前言

网络上有很多关于SpringBoot引入Swagger的教程，但是大多是针对Swagger2.x版本的教程，本着一个程序员的优良传统，我使用了Swagger3.0.0，结果踩了不少坑，在此记录一下，也方便后来者

Swagger3.x的不同

访问地址的不同

Swagger3.x：

1	http://localhost:8080/swagger-ui/index.html

Swagger2.x：

1	http://localhost:8080/swagger-ui.html

Swagger3.x的引入更加简洁方便

pom文件中只需写一个

<dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-boot-starter</artifactId>
       <version>3.0.0</version>
 </dependency>

注释添加（只需要在启动项添加一个@EnableOpenAi）

@EnableOpenAi
@SpringBootApplication
public class MyFirstSpringBootApplication {

	public static void main(String[] args) {
		SpringApplication.run(MyFirstSpringBootApplication.class, args);
	}

}

Swagger配置类

package com.dreaminglri.myfirstspringboot.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;

@EnableOpenApi
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.OAS_30)
                .enable(true)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("MyFirstSpringBoot")
                .description("a project of my first spring boot learning")
                .version("1.0")
                .build();
    }
}
