springboot2集成knife4j 环境说明集成knife4j 第一步引入依赖第二步编写配置类第三步测试一下 第一小步编写controller第二小步启动项目访问api文档 相关资料
环境说明
springboot2.6.4knife4j-openapi2-spring-boot-starter4.0.0
集成knife4j
第一步引入依赖
dependencygroupIdcom.github.xiaoymin/groupIdartifactIdknife4j-openapi2-spring-boot-starter/artifactIdversion4.0.0/version
/dependency第二步编写配置类 提示可以借助配置文件进一步改造 import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RestController;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2WebMvc;/*** Knife4j配置** author font size 20 color #3CAA3Ca hrefhttps://gitee.com/JustryDengJustryDeng/a/font img* srchttps://gitee.com/JustryDeng/shared-files/raw/master/JustryDeng/avatar.jpg /* since 1.0.0*/
Slf4j
Configuration
EnableSwagger2WebMvc
public class Knife4jConfig {Value(${spring.application.name:default})private String applicationName;Beanpublic Docket docket() {// 指定使用Swagger2规范return new Docket(DocumentationType.SWAGGER_2).apiInfo(new ApiInfoBuilder()// 简介(支持Markdown语法).description(# 我是API简介)// 服务地址.termsOfServiceUrl(http://local.idea-aedi.com/)// 作者及联系信息.contact(new Contact(JustryDeng, https://gitee.com/JustryDeng, 13548417409163.com))// api版本.version(1.0.0).build())//分组名称(微服务项目可以用微服务名分组).groupName(applicationName).select()// 定位api.apis(RequestHandlerSelectors.basePackage(getProjectBasePackage()).and(RequestHandlerSelectors.withClassAnnotation(RestController.class).or(RequestHandlerSelectors.withClassAnnotation(Controller.class)))).paths(PathSelectors.any()).build();}/*** 获取项目包前缀*/private String getProjectBasePackage() {String projectBasePackage;String currPackageName this.getClass().getPackage().getName();String[] packageItemArr currPackageName.split(\\.);if (packageItemArr.length 3) {projectBasePackage String.join(., packageItemArr[0], packageItemArr[1], packageItemArr[2]);} else {projectBasePackage currPackageName;}log.info(Base package to scan api is - {}, projectBasePackage);return projectBasePackage;}}第三步测试一下
第一小步编写controller
import com.ideaaedi.demo.controller.model.UserAddReqVO;
import com.ideaaedi.demo.controller.model.UserDetailRespVO;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;/*** 用于测试knife4j的controller** author font size 20 color #3CAA3Ca hrefhttps://gitee.com/JustryDengJustryDeng/a/font img* srchttps://gitee.com/JustryDeng/shared-files/raw/master/JustryDeng/avatar.jpg /* since 1.0.0*/
RestController
Api(tags 我是DemoController)
public class TestController {GetMapping(/hello)ApiOperation(value 哈喽)public String hello(ApiParam(name name, value 姓名, required true)RequestParam String name) {return hello name;}PostMapping(/user/add)ApiOperation(value 新增用户)public UserDetailRespVO addUser(RequestBody UserAddReqVO req) {UserDetailRespVO resp new UserDetailRespVO();resp.setId(9527L);resp.setName(req.getName());resp.setAge(req.getAge());return resp;}DeleteMapping(/user/delete/{id})ApiOperation(value 删除用户)public Boolean addUser(ApiParam(name id, value 数据id, required true) PathVariable Long id) {return true;}/*** 测试 RequestBody、RequestParam、PathVariable并存*/PostMapping(/multi-anno/{id})ApiOperation(value 组合使用测试)ApiParampublic UserDetailRespVO testMultiAnno(RequestBody UserAddReqVO req,ApiParam(name name, value 姓名, required true)RequestParam String name,ApiParam(name id, value 数据id, required true)PathVariable Long id) {UserDetailRespVO resp new UserDetailRespVO();resp.setId(9527L);resp.setName(req.getName());resp.setAge(req.getAge());return resp;}}此controller中用到的相关模型 UserAddReqVO import io.swagger.annotations.ApiModelProperty;
import lombok.Data;import javax.validation.constraints.NotBlank;/*** 用户新增req模型*/
Data
public class UserAddReqVO {ApiModelProperty(value 姓名,required true)NotBlank(message 姓名不能为空)private String name;ApiModelProperty(年龄)private Integer age;
}UserDetailRespVO import io.swagger.annotations.ApiModelProperty;
import lombok.Data;/*** 用户详情resp模型*/
Data
public class UserDetailRespVO {ApiModelProperty(id)private Long id;ApiModelProperty(姓名)private String name;ApiModelProperty(年龄)private Integer age;
}第二小步启动项目访问api文档 启动项目后直接访问http://{ip}:{端口}/doc.html即可 说明
文档分组可切换观察其余分组下的api主页概览Swagger Models可以查看所有请求模型的信息文档管理可以导出文档、进行高级设置如设置后处理脚本等、进行全局参数设置、查看api信息点击进入文档后会展示api的详细信息也可以进行调试还可以打开api json数据等等
