swagger-boostrap-ui从1.x版本到如今2.x，同时也更改名字Knife4j

在此记录下 knife4j-spring-boot-starter 的整合。

只需要引入knife4j-spring-boot-starter，无需引入其他的swagger包，knife4j-spring-boot-starter已经包含。

官方版本说明

<dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-spring-boot-starter</artifactId><version>2.0.8</version>
</dependency>

包结构

swagger配置：

package com.example.demo.config;import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;/*** @author* @description* @since 2023/8/31*/
@Configuration
@EnableKnife4j
public class SwaggerConfig {/*** 不同包情况下  bi包*/@Beanpublic Docket createRestBiApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("报表管理").select().apis(RequestHandlerSelectors.basePackage("com.example.demo.bi.controller")).paths(PathSelectors.any()).build();}/*** 不同包情况下  system包*/@Beanpublic Docket createRestSystemApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("系统管理").select().apis(RequestHandlerSelectors.basePackage("com.example.demo.system.controller")).paths(PathSelectors.any()).build();}/*** 同包情况下路径不同  同在system包下，book开头的单独分组*/@Beanpublic Docket createRestBookApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("图书管理").select().apis(RequestHandlerSelectors.basePackage("com.example.demo.system.controller")).paths(PathSelectors.regex("/book/.*")).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("2023_demo API管理").description("2023_demo API 1.0").build();}}

yml配置（必须）

spring:mvc:pathmatch:matching-strategy: ant_path_matcher

结果：
