问题

配置Swagger后,访问http://localhost:8080/swagger-ui.html不显示页面

不同的版本可能路径不同,可以尝试:

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

原因

Swagger版本过高

我尝试降低springboot版本到2.2.6.RELEASE结果还是不行,然后将Swagger版本从3.0降到2.9.2就可以访问了,随后我又将springboot版本还原,还是可以访问,最后得出Swagger版本不能太高

整体实现

maven 依赖

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

swagger 配置

package com.liu.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.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.util.ArrayList;

@Configuration
@EnableSwagger2 //开启了swagger2
public class SwaggerConfig {
    //配置了swagger的Docker的bean实例
    @Bean
    public Docket docket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //包下的类,生成接口文档
                .build();
    }

    //配置Swagger信息
    private ApiInfo apiInfo() {
//        作者信息
        Contact contact = new Contact("小柳", "https://www.baidu.com", "1811961890@qq.com");
        return new ApiInfoBuilder()
                .contact(contact)
                .title("充电了")
                .description("打卡!!!")
                .termsOfServiceUrl("https://www.baidu.com")
                .version("3.0")
                .build();
    }
}

配置Controller

package com.liu.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @RequestMapping("/hello")
    public String hello(){
        return "欢迎使用!!!!";
    }
}
