一.Swagger

1.Swagger简介

swagger 是一款RESTFUL接口的文档在线自动生成+功能测试功能软件.
Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法，参数和模型紧密集成到服务器端的代码，允许API来始终保持同步。Swagger 让部署管理和使用功能强大的API从未如此简单.

2.Swagger注解

@Api：用在请求的类上，表示对类的说明
- tags="说明该类的作用，可以在UI界面上看到的注解"
- value="该参数没什么意义，在UI界面上也看到，所以不需要配置"
```
@Api(tags="APP用户注册Controller")
```
@ApiOperation：用在请求的方法上，说明方法的用途、作用
- value="说明方法的用途、作用"
- notes="方法的备注说明"
```
@ApiOperation(value="用户注册",notes="手机号、密码都是必输项，年龄随边填，但必须是数字")
```

@ApiParam：用于方法，参数，字段说明，表示对参数的添加元数据（说明或是否必填等）

name:属性名称
value：属性值
defaultValue：默认属性值
required：是否属性必填
example：举例子

@ApiOperation(value = "传设置过期时间")
@RequestMapping(value = "/expire", method = RequestMethod.POST)
public boolean expire(@ApiParam(name = "key", value = "cache key", required = true) @RequestParam("key")String key,@ApiParam(name = "expireSecond", value = "key过期时间:秒", required = true)@RequestParam("expireSecond") Integer expireSecond){
  checkParams(key);
  log.info("key:{},", key);
  return redisService.expire(key, expireSecond);
}

@ApiImplicitParams：用在请求的方法上，表示一组参数说明
- @ApiImplicitParam：用在@ApiImplicitParams注解中，指定一个请求参数的各个方面
  - name：参数名
  - value：参数的汉字说明、解释
  - required：参数是否必须传
  - paramType：参数放在哪个地方
    - header --> 请求参数的获取：@RequestHeader
    - query --> 请求参数的获取：@RequestParam
    - path（用于restful接口）--> 请求参数的获取：@PathVariable
    - body（不常用）
    - form（不常用）
  - dataType：参数类型，默认String，其它值dataType="Integer"
  - defaultValue：参数的默认值
```
@ApiImplicitParams({
  @ApiImplicitParam(name="mobile",value="手机号",required=true,paramType="form"),
  @ApiImplicitParam(name="password",value="密码",required=true,paramType="form"),
  @ApiImplicitParam(name="age",value="年龄", required=true,paramType="form",dataType="Integer")
})
```

@ApiResponses：用在请求的方法上，表示一组响应

@ApiResponse：用在@ApiResponses中，一般用于表达一个错误的响应信息
- code：数字，例如400
- message：信息，例如"请求参数没填好"
- response：抛出异常的类

@ApiOperation(value = "select1请求",notes = "多个参数，多种的查询参数类型")
@ApiResponses({
  @ApiResponse(code=400,message="请求参数没填好"),
  @ApiResponse(code=404,message="请求路径没有或页面跳转路径不对")
})

@ApiModel：用于响应类上，表示一个返回响应数据的信息（这种一般用在post创建的时候，使用@RequestBody这样的场景，请求参数无法使用@ApiImplicitParam注解进行描述的时候）

@ApiModelProperty：用在属性上，描述响应类的属性

@ApiModel(description= "返回响应数据")
public class RestMessage implements Serializable{
    @ApiModelProperty(value = "是否成功")
    private boolean success=true;
    @ApiModelProperty(value = "返回对象")
    private Object data;
    @ApiModelProperty(value = "错误编号")
    private Integer errCode;
    @ApiModelProperty(value = "错误信息")
    private String message;
    /* getter/setter */
}

二.SpringBoot整合Swagger

1.新建SpringBoot项目

</project>

3.resource包下新建application.yml文件

也可以使用application.properties进行配置

server:
  port: 8080
  # 指定端口
spring:
  # 配置数据源
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://localhost:3307/datatest?useSSL=false&serverTimezone=UTC&characterEncoding=utf-8
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: root
# 配置mybatis
mybatis:
  type-aliases-package: com.ym.pojo
  mapper-locations: classpath*:mapper/*Mapper.xml
# 日志
logging:
  level:
    root: info  #使用error级别,项目启动不起来,原因还在排查中
  file:
    path: mylog   #日志文件所在的包路径
# 配置swagger
swagger:
  basePackage: com.ym
  title: User CRUD SpringBoot Swagger
  version: v1.0
  description: this is a user crud function
  contact: YanM
  url: www.ym.com

4.创建swagger2的配置类

package com.ym.config;

import org.springframework.beans.factory.annotation.Value;
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.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Value ("${swagger.basePackage}")
    private String basePackage; //扫描controller的包名

    @Value ("${swagger.title}")
    private String title;  //在线文档的标题

    @Value ("${swagger.version}")
    private String version;  //文档的版本

    @Value ("${swagger.description}")
    private String description;  //在线文档的描述

    @Value ("${swagger.contact}")
    private String contact; //联系人

    @Value ("${swagger.url}")
    private String url; //URL

    @Bean
    public Docket api(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())   //函数返回一个ApiSelectorBuilder实例来控制哪些接口暴露给swagger来展现
                .select()
                .apis(RequestHandlerSelectors.basePackage(basePackage))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title(title)
                .description(description)
                .termsOfServiceUrl(url)
                .version(version)
                .contact(new Contact(contact,url,url))
                .build();
    }
}

5.pojo层

package com.ym.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int uid;
    private String name;
    private String sex;
    private int age;
    private String address;
}

6.dao层接口

接口上需要@Mapper注解

package com.ym.dao;

import com.ym.pojo.User;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

@Mapper
public interface IUserDao {
    List<User> getAllUsers();

    User getUserByUid(int uid);

    int editUser(User user);

    int deleteUserByUid(int uid);

    int saveUser(User user);
}

7.与dao层接口对应的mapper文件

最好在添加一个resultMap

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 整个映射文件为mapper节点，里面包含namespace属性 -->
<mapper namespace="com.ym.dao.IUserDao">

    <sql id="all">
        select * from users
    </sql>

    <select id="getAllUsers" resultType="user">
        <include refid="all" />
    </select>


    <select id="getUserByUid" resultType="user">
        select * from users where uid=#{uid}
    </select>

    <update id="editUser">
        update users
        <set>
            <if test="name != null and name != ''">
                name = #{name},
            </if>
            <if test="sex != null and sex != ''">
                sex = #{sex},
            </if>
            <if test="age != 0">
                age = #{age},
            </if>
            <if test="address != null and address != ''">
                address = #{address},
            </if>
        </set>
        where uid = #{uid}
    </update>

    <delete id="deleteUserByUid">
        delete from users where uid=#{uid}
    </delete>

    <insert id="saveUser">
        insert into users values (default ,#{name},#{sex},#{age},#{address})
    </insert>
</mapper>

8.service层接口

package com.ym.service;

import com.ym.pojo.User;

import java.util.List;


public interface IUserService {
    List<User> getAllUsers();

    int editUser(User user);

    int deleteUserByUid(int uid);

    int saveUser(User user);
}

9.service层实现类

package com.ym.service.impl;

import com.ym.dao.IUserDao;
import com.ym.pojo.User;
import com.ym.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;


@Service
public class UserService implements IUserService {

    @Resource
    private IUserDao userDao;

    @Override
    public List<User> getAllUsers() {
        return userDao.getAllUsers();
    }

    @Override
    public User getUserByUid(int uid) {
        return userDao.getUserByUid(uid);
    }

    @Override
    public int editUser(User user) {
        return userDao.editUser(user);
    }

    @Override
    public int deleteUserByUid(int uid) {
        return userDao.deleteUserByUid(uid);
    }

    @Override
    public int saveUser(User user) {
        return userDao.saveUser(user);
    }
}

10.controller层

package com.ym.controller;

import com.ym.pojo.User;
import com.ym.service.IUserService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;
import java.util.List;


@RestController
@Api(tags = "操作用户信息-UserController")
public class UserController {

    @Resource
    private IUserService userService;

    @GetMapping("/allUser")
    @ApiOperation(value = "获取所有的用户信息")
    public List<User> queryAllUser(){
        List<User> users = userService.getAllUsers();
        return users;
    }


    @PostMapping("/editUser")
    @ApiOperation(value = "修改用户信息")
    public void editUser(User user){
        userService.editUser(user);
    }


    @GetMapping("/deleteUser/{uid}")
    @ApiOperation(value = "删除用户")
    public void deleteUser(@PathVariable int uid){
        userService.deleteUserByUid(uid);
    }

    @PostMapping("/saveUser")
    @ApiOperation(value = "保存用户信息")
    public void saveUser(User user){
        userService.saveUser(user);
    }
}
