import org.springframework.beans.factory.annotation.Autowired; 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; import springfox.documentation.swagger2.annotations.EnableSwagger2WebMvc;/*** Knife4j配置类* author heyunlin* version 1.0/ Configuration EnableSwagger2WebMvc public class Knife4jConfig {// 指定Controller包路径必须private static final String basePackage cn.edu.sgu.www.knife4j.controller;private static final String host LAPTOP-0N6P8HTP;private static final String title Spring Boot整合Knife4j案例项目;private static final String description title 在线API文档;private static final String termsOfServiceUrl https://www.apache.org/licenses/LICENSE-2.0;private static final String contactName heyunlin;

import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;/** author heyunlin* version 1.0/ Api(tags 用户管理) RestController RequestMapping(/user) public class UserController {ApiOperation(登录认证)PostMapping(login)public String login(UserLoginDTO userLoginDTO) {return 登录成功;}} 创建传输对象实体类 package cn.edu.sgu.www.knife4j.dto;import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data;/** author heyunlin* version 1.0/ Data ApiModel public class UserLoginDTO {ApiModelProperty(value 用户名, required true)private String username;ApiModelProperty(value 密码, required true)private String password; } 除此之外Knife4j还提供了使用在参数上的注解如ApiParam package cn.edu.sgu.www.knife4j.controller;import cn.edu.sgu.www.knife4j.dto.UserLoginDTO; import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import io.swagger.annotations.ApiParam; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;/** author heyunlin* version 1.0*/ Api(tags 用户管理) RestController RequestMapping(/user) public class UserController {ApiOperation(登录认证)PostMapping(/login)public String login(UserLoginDTO userLoginDTO) {return 登录成功;}ApiOperation(用户注册)PostMapping(/register)public String register(ApiParam(value 用户名, required true) String username,ApiParam(value 密码, required true) String password) {return 注册成功;}} 最后启动项目访问localhost:端口号/doc.html 好了文章就分享到这里了代码已经上传到gitee可按需获取~ Spring Boot整合Knife4j案例项目https://gitee.com/he-yunlin/springboot-knife4j.git
