Spring Boot3整合knife4j(swagger3)

在Spring Boot 3中整合Knife4j（Swagger 3的升级版），首先需要引入Knife4j的依赖，然后配置Swagger 3。以下是一个简单的示例：

1. 在pom.xml中添加Knife4j的依赖：

<dependencies>
    <!-- 添加Knife4j依赖 -->
    <dependency>
        <groupId>com.github.xiaoymin</groupId>
        <artifactId>knife4j-spring-boot-starter</artifactId>
        <version>3.0.3</version>
    </dependency>
</dependencies>

2. 在application.properties或application.yml中配置Knife4j：

# 配置Knife4j的基本路径，默认可以不配置
knife4j:
  basic:
    enable: true
    # 基本路径
    path: /doc

3. 在Spring Boot启动类上添加@EnableKnife4j注解启用Knife4j：

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
@EnableKnife4j // 启用Knife4j
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

4. 创建一个Swagger配置类，配置Swagger的基本信息：

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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
 
@Configuration
@EnableKnife4j
public class SwaggerConfig {
 
    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        Docket docket=new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
 
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Knife4j 示例")
                .description("这是一个使用Knife4j的Swagger3接口文档")
                .contact(new Contact("开发者名字", "http://example.com", "example@example.com"))
                .version("1.0")
                .build();
    }
}

5. 创建一个Controller类，添加Swagger注解：
