创建 Maven 工程

参考：https://www.cnblogs.com/TangXiaoHuiHui/articles/12264019.html 进行创建

添加相关依赖

添加启动类

/**
 * @author BNTang
 * @version V1.0
 * @project SpringBoot-ElasticSearch-Pro
 * @date Created in 2022/3/5 /005 15:21
 * @description 启动类
 **/
@SpringBootApplication
@EnableSwagger2
@EnableSwaggerBootstrapUI
public class ElasticSearchApplication {
    public static void main(String[] args) {
        SpringApplication.run(ElasticSearchApplication.class, args);
    }
}

配置 swagger

/**
 * @author BNTang
 * @version V1.0
 * @project SpringBoot-ElasticSeach-Pro
 * @date Created in 2022/3/5 /005 15:19
 * @description swagger 相关配置
 **/
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket createH5RestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }
    
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("elasticSearch api文档")
                .description("restful 风格接口")
                .version("1.0")
                .build();
    }
}

到了这一步，博主在启动项目的时候发现报错了：

居然原因呢，是因为博主这里用的 SpringBoot 版本是最新的，最近对 Spring Boot 2.6.0 的文档进行研究发现，2.6.0 开始使用基于 PathPatternParser 的路径匹配，而 Springfox 版本一直没有更新还是使用的 AntPathMatcher 导致了这个问题，要处理问题也很简单，修改 yaml 文件，将 SpringBoot 路劲匹配模式修改为 AntPathMatcher 就可以了，配置如下：spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER。

创建 yml 配置文件

application.yml：

spring:
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER
