springboot 版本2.3.1

一、集成swagger3

1. 引入swagger依赖包

<!--swagger3集成--><dependency><groupId>org.springframework.plugin</groupId><artifactId>spring-plugin-core</artifactId><version>2.0.0.RELEASE</version></dependency><dependency><groupId>org.springframework.plugin</groupId><artifactId>spring-plugin-metadata</artifactId><version>2.0.0.RELEASE</version><exclusions><exclusion><artifactId>spring-plugin-core</artifactId><groupId>org.springframework.plugin</groupId></exclusion></exclusions></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-boot-starter</artifactId><version>3.0.0</version><exclusions><exclusion><groupId>org.springframework.plugin</groupId><artifactId>spring-plugin-core</artifactId></exclusion><exclusion><groupId>org.springframework.plugin</groupId><artifactId>spring-plugin-metadata</artifactId></exclusion></exclusions></dependency>

开启 swagger-ui.html的图形化界面开关

springfox:documentation:swagger-ui:enabled: true

3. 增加swager3 配置类和文档配置说明

mport io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import springfox.documentation.builders.*;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.schema.ScalarType;
import springfox.documentation.service.*;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import java.util.ArrayList;
import java.util.List;@Configuration
@EnableOpenApi
public class Swagger3Config {@Beanpublic Docket createRestApi(){//返回文档概要信息return new Docket(DocumentationType.OAS_30).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).paths(PathSelectors.any()).build().globalRequestParameters(getGlobalRequestParameters()).globalResponses(HttpMethod.GET,getGlobalResponseMessage()).globalResponses(HttpMethod.POST,getGlobalResponseMessage());}/*生成接口信息，包括标题，联系人等*/private ApiInfo apiInfo() {return new ApiInfoBuilder().title("Swagger3接口文档").description("组件接口文档").version("1.0").build();}/*封装全局通用参数*/private List<RequestParameter> getGlobalRequestParameters() {List<RequestParameter> parameters=new ArrayList<>();parameters.add(new RequestParameterBuilder().name("uuid").description("设备uuid").required(true).in(ParameterType.QUERY).query(q->q.model(m->m.scalarModel((ScalarType.STRING)))).required(false).build());return parameters;}//    封装通用相应信息private List<Response> getGlobalResponseMessage() {List<Response> responseList=new ArrayList<>();responseList.add(new ResponseBuilder().code("404").description("未找到资源").build());return responseList;}

4.本地访问地址

本地swagger 文档地址：http://127.0.0.1:10008/swagger-ui/index.html#

二、基于Knife4j导出离线API 配置

Knife4j是一款基于Swagger 2的在线API文档框架，是日常开发中很常用的框架，基于此框架，后端可以和前端开发人员进行高效沟通。

2.1 导入配置pom
添加Knife4j的依赖（当前建议使用的Knife4j版本，只适用于Spring Boot 2.6以下版本，不含Spring Boot 2.6）

   <!--swagger Knife4j导出配置--><!--Knife4j--><dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-spring-boot-starter</artifactId><version>3.0.2</version></dependency>

2.2 开启Knife4j增加注解和swagger导出ui关闭

knife4j:enable: true
springfox:documentation:swagger-ui:enabled: false

3 .启用Knife4j 功能
在启动类增加注解@EnableKnife4j ，开启Knife4j 功能

@EnableKnife4j
