SpringBoot3整合Knife4j

前置：

官网：快速开始 | Knife4j

gitee：swagger-bootstrap-ui-demo: knife4j 以及swagger-bootstrap-ui 集成框架示例项目 - Gitee.com

1.依赖引入：

ps：json处理需要引入相关包

        <dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-openapi3-jakarta-spring-boot-starter</artifactId><version>4.4.0</version></dependency>
#相关处理需要json解析,这个几个库必须加上<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.10.1</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.10.1</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-annotations</artifactId><version>2.10.1</version></dependency>

2.配置类：

@Configuration
public class SwaggerConfig {/*** 根据@Tag 上的排序，写入x-order** @return the global open api customizer*/@Beanpublic GlobalOpenApiCustomizer orderGlobalOpenApiCustomizer() {return openApi -> {if (openApi.getTags()!=null){openApi.getTags().forEach(tag -> {Map<String,Object> map=new HashMap<>();map.put("x-order", RandomUtil.randomInt(0,100));tag.setExtensions(map);});}if(openApi.getPaths()!=null){openApi.addExtension("x-test123","333");openApi.getPaths().addExtension("x-abb",RandomUtil.randomInt(1,100));}};}@Beanpublic OpenAPI customOpenAPI() {return new OpenAPI().info(new Info().title("XXX用户系统API").version("1.0").description( "Knife4j集成springdoc-openapi示例").termsOfService("http://doc.xiaominfo.com").license(new License().name("Apache 2.0").url("http://doc.xiaominfo.com")));}
}

3.yml中的配置

packages-to-scan: com.xiaominfo.knife4j.demo.web#需要改位置

# springdoc-openapi项目配置
springdoc:swagger-ui:path: /swagger-ui.htmltags-sorter: alphaoperations-sorter: alphaapi-docs:path: /v3/api-docsgroup-configs:- group: 'default'paths-to-match: '/**'
#包的扫描需要修改对应位置packages-to-scan: com.xiaominfo.knife4j.demo.web#需要改位置
# knife4j的增强配置，不需要增强可以不配
