甩掉接口文档烦恼！Spring Boot 集成 Knife4j，轻松玩转 API 可视化

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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
 
@Configuration
public class Knife4jConfiguration {
 
    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        Docket docket=new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                // 指定扫描的包路径
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
 
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Knife4j 测试")
                .description("Knife4j 测试文档")
                .version("1.0")
                .build();
    }
}

这段代码演示了如何在Spring Boot项目中配置Knife4j，通过Knife4jConfiguration类创建一个Docket Bean，并设置API信息。这样就可以通过http://<host>:<port>/doc.html访问API文档，进一步可视化接口信息，提高开发和维护效率。
