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")
@RestController
public 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;
    }

    @Override
    public 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
@EnableSwagger2
public 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;


@SpringBootApplication
public class AppSwagger {
   public static void main(String[] args) {
      SpringApplication.run(AppSwagger.class, args);
   }
}

　　3.5 application.yml

server:
  port: 8080
spring:
  application:
    name: swagger

4. 启动项目

　　4.1 项目启动成功之后,浏览器访问http://localhost:8080/swagger-ui.html

　　

　　4.2 测试addUser接口

　　

 　点击Execute提交请求,

　　请求成功,其它接口可自行测试,皆正常!!!
