讲在前面：在spring引入swagger时，由于使用的JDK、Spring、swagger 的版本不匹配，导致启动报错，一直存在版本依赖问题。所以在此声明清楚使用版本。JDK 1.8、Spring boot 2.6.13、 Swagger 2.9.2。
- 引入maven依赖
<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>
- 引入配置文件 swaggerConfiger
package com.example.swaggertest.demos.web;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import springfox.documentation.builders.ApiInfoBuilder;
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 org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;@Configuration
@EnableWebMvc
@EnableSwagger2
public class SwaggerConfig implements WebMvcConfigurer {@Beanpublic Docket ApiConfig() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().build();}private ApiInfo apiInfo(){return new ApiInfoBuilder().title("swagger api demo").description("swagger api demo").version("1.0").contact(new Contact("测试", "http://XXXX", "xxx@163.com")).build();}@Override //开发swagger-ui.html 接口，否则，请求localhost/8080/swagger-ui.html 报错：不存在该mappingpublic void addResourceHandlers(ResourceHandlerRegistry registry) {registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");}}
