springboot整合swagger2

近来发现knife4j比swagger2整合起来方便，功能也更强大，推荐使用， 具体可参考 springboot2整合knife4j

1.目的:使用Swagger2发布接口,ui可操作

2.项目结构

 3. 代码

 3.1 接口类qinfeng.zheng.api.controller.DemoController

import io.swagger.annotations.Api;import io.swagger.annotations.ApiImplicitParam;import io.swagger.annotations.ApiImplicitParams;import io.swagger.annotations.ApiOperation;import org.springframework.web.bind.annotation.*;import qinfeng.zheng.api.entity.UserEntity;@Api(value = "会员接口")@RestControllerpublic class DemoController {    @ApiOperation(value = "swagger接口测试demo", nickname = "swagger接口测试demo昵称")    @GetMapping("/getDemo")public String getDemo() {return "getDemo方法调用成功...";    }    @ApiOperation(value = "获取会员信息接口", nickname = "根据userName获取用户相关信息")    @ApiImplicitParam(name = "userName", value = "用户名称", required = true, dataType = "String")    @PostMapping("/postMember")public String postMember(@RequestParam String userName) {return userName;     }    @ApiOperation(value = "添加用户信息", nickname = "nickname是什么", notes = "notes是什么", produces = "application/json")    @PostMapping("/postUser")    @ResponseBody    @ApiImplicitParam(paramType = "query", name = "userId", value = "用户id", required = true, dataType = "int")public UserEntity postUser(@RequestBody UserEntity user, @RequestParam("userId") int userId) { // 这里用包装类竟然报错if (user.getId() == userId) {return user;        }return new UserEntity();    }    @ApiOperation(value = "添加用户信息", nickname = "哈哈测试", notes = "哈哈测试添加用户", produces = "application/json")     @PostMapping("/addUser")    @ResponseBody    @ApiImplicitParams({            @ApiImplicitParam(paramType = "query", name = "userName", value = "用户姓名", required = true, dataType = "String"),             @ApiImplicitParam(paramType = "query", name = "id", value = "用户id", required = true, dataType = "int") })public UserEntity addUser(String userName, int id) {        UserEntity userEntity = new UserEntity();        userEntity.setName(userName);        userEntity.setId(id);return userEntity;    }}

　　3.2 实体类qinfeng.zheng.api.entity.UserEntity

package qinfeng.zheng.api.entity;import io.swagger.annotations.ApiModel;import io.swagger.annotations.ApiModelProperty;/** * 创建时间: 23:09 2018/9/19 * 修改时间: * 编码人员: ZhengQf * 版   本: 0.0.1 * 功能描述: */@ApiModel(value = "用户模型")public class UserEntity {    @ApiModelProperty(value="id" ,required= true,example = "123")private Integer id;    @ApiModelProperty(value="用户姓名" ,required=true,example = "郑钦锋")private String name;public Integer getId() {return id;    }public void setId(Integer id) {this.id = id;    }public String getName() {return name;    }public void setName(String name) {this.name = name;    }    @Overridepublic String toString() {return "DemoDoctor [id=" + id + ", name=" + name + "]";    }}

　　3.3 配置类qinfeng.zheng.config.SwaggerConfig

package qinfeng.zheng.config;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;import springfox.documentation.swagger2.annotations.EnableSwagger2;/** * swagger2的配置类 */@Configuration@EnableSwagger2public class SwaggerConfig {   @Bean   public Docket createRestApi() {      return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()// api扫包范围.apis(RequestHandlerSelectors.basePackage("qinfeng.zheng.api")).paths(PathSelectors.any()).build();   }/** * 创建该API的基本信息（这些基本信息会展现在文档页面中）     * 访问地址：http://项目实际地址/swagger-ui.html     * @return */   private ApiInfo apiInfo() {      return new ApiInfoBuilder().title("Swagger接口发布测试").description("测试|Swagger接口功能")            .termsOfServiceUrl("http://www.baidu.com")            .version("1.0").build();   }}

　　3.4 启动类qinfeng.zheng.AppSwagger

package qinfeng.zheng;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class AppSwagger {   public static void main(String[] args) {      SpringApplication.run(AppSwagger.class, args);   }}

　　3.5 application.yml
