1、簡介

Swagger 是一個規範和完整的框架，用於生成、描述、調用和可視化 RESTful 風格的 Web 服務。整體目標是使客戶端和文件系統做爲服務器以一樣的速度來更新 。接口的方法，參數和模型緊密集成到服務器端的代碼，容許API來始終保持同步。Swagger 讓部署管理和使用功能強大的API從未如此簡單。html

咱們的RESTful API就有可能要面對多個開發人員或多個開發團隊：IOS開發、Android開發、Web開發等。爲了減小與其餘團隊平時開發期間的頻繁溝通成本，傳統作法咱們會建立一份RESTful API文檔來記錄全部接口細節，然而這樣的作法有如下幾個問題：java

  1. 因爲接口衆多，而且細節複雜（須要考慮不一樣的HTTP請求類型、HTTP頭部信息、HTTP請求內容等），高質量地建立這份文檔自己就是件很是吃力的事，下游的抱怨聲不絕於耳；
  2. 隨着時間推移，不斷修改接口實現的時候都必須同步修改接口文檔，而文檔與代碼又處於兩個不一樣的媒介，除非有嚴格的管理機制，否則很容易致使不一致現象；

而swagger完美的解決了上面的幾個問題，並與Spring MVC程序配合組織出強大RESTful API文檔。它既能夠減小咱們建立文檔的工做量，同時說明內容又整合入實現代碼中，讓維護文檔和修改代碼整合爲一體，可讓咱們在修改代碼邏輯的同時方便的修改文檔說明。另外Swagger2也提供了強大的頁面測試功能 來調試每一個RESTful API。git

2、添加Swagger2依賴

<dependency>
     <groupId>io.springfox</groupId>
     <artifactId>springfox-swagger2</artifactId>
     <version>2.6.1</version>
</dependency>
<dependency>
     <groupId>io.springfox</groupId>
     <artifactId>springfox-swagger-ui</artifactId>
     <version>2.6.1</version>
</dependency>
<dependency>  
     <groupId>com.fasterxml.jackson.core</groupId>  
     <artifactId>jackson-core</artifactId>  
     <version>2.6.5</version>  
</dependency>  
<dependency>  
     <groupId>com.fasterxml.jackson.core</groupId>  
     <artifactId>jackson-databind</artifactId>  
     <version>2.6.5</version>  
</dependency>  
<dependency>  
     <groupId>com.fasterxml.jackson.core</groupId>  
     <artifactId>jackson-annotations</artifactId>  
     <version>2.6.5</version>  
</dependency>

3、建立Swagger2配置類

package com.xia.common.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import io.swagger.annotations.ApiOperation;
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;

/** * 類描述：配置swagger2信息 * 建立人：XiaChengwei * 建立時間：2017年7月28日 上午10:03:29 * @version 1.0 */
@Configuration      //讓Spring來加載該類配置
@EnableWebMvc       //啓用Mvc，非springboot框架須要引入註解@EnableWebMvc
@EnableSwagger2     //啓用Swagger2
public class Swagger2Config {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo()).select()
                //掃描指定包中的swagger註解
                //.apis(RequestHandlerSelectors.basePackage("com.xia.controller"))
                //掃描全部有註解的api，用這種方式更靈活
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("基礎平臺 RESTful APIs")
                .description("基礎平臺 RESTful 風格的接口文檔，內容詳細，極大的減小了先後端的溝通成本，同時確保代碼與文檔保持高度一致，極大的減小維護文檔的時間。")
                .termsOfServiceUrl("http://xiachengwei5.coding.me")
                .contact("Xia")
                .version("1.0.0")
                .build();
    }
}

4、編寫swagger註解

實體類：github

package com.xia.model;

import java.util.Date;
import org.springframework.format.annotation.DateTimeFormat;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonInclude;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
/** * 人員信息表 * 註解：@ApiModel 和 @ApiModelProperty 用於在經過對象接收參數時在API文檔中顯示字段的說明 * 註解：@DateTimeFormat 和 @JsonFormat 用於在接收和返回日期格式時將其格式化 * 實體類對應的數據表爲： user_info * @author XiaChengwei * @date: 2017-07-14 16:45:29 */
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties({ "handler","hibernateLazyInitializer" }) 
@ApiModel(value ="UserInfo")
public class UserInfo {
    @ApiModelProperty(value = "ID")
    private Integer id;

    @ApiModelProperty(value = "用戶登陸帳號", required = true)
    private String userNo;

    @ApiModelProperty(value = "姓名", required = true)
    private String userName;
    
    @ApiModelProperty(value = "姓名拼音")
    private String spellName;

    @ApiModelProperty(value = "密碼", required = true)
    private String password;

    @ApiModelProperty(value = "手機號", required = true)
    private String userPhone;

    @ApiModelProperty(value = "性別")
    private Integer userGender;

    @ApiModelProperty(value = "記錄建立時間")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date createTime;

    @ApiModelProperty(value = "記錄修改時間")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date updateTime;
    
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
    
    public String getUserNo() {
        return userNo;
    }

    public void setUserNo(String userNo) {
        this.userNo = userNo == null ? null : userNo.trim();
    }
    
    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName == null ? null : userName.trim();
    }
    
    public String getSpellName() {
        return spellName;
    }

    public void setSpellName(String spellName) {
        this.spellName = spellName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }
   
    public String getUserPhone() {
        return userPhone;
    }

    public void setUserPhone(String userPhone) {
        this.userPhone = userPhone == null ? null : userPhone.trim();
    }
    
    public Integer getUserGender() {
        return userGender;
    }

    public void setUserGender(Integer userGender) {
        this.userGender = userGender;
    }
  
    @JsonFormat(locale = "zh", timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    @JsonFormat(locale = "zh", timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(getClass().getSimpleName());
        sb.append(" [");
        sb.append("Hash = ").append(hashCode());
        sb.append(", id=").append(id);
        sb.append(", userNo=").append(userNo);
        sb.append(", userName=").append(userName);
        sb.append(", spellName=").append(spellName);
        sb.append(", password=").append(password);
        sb.append(", userPhone=").append(userPhone);
        sb.append(", userGender=").append(userGender);
        sb.append(", createTime=").append(createTime);
        sb.append(", updateTime=").append(updateTime);
        sb.append("]");
        return sb.toString();
    }
}

5、訪問

配置完成以後重啓服務器，訪問地址 http://localhost:8080/項目名/swagger-ui.html，如：spring

http://localhost:8080/spring-mvc/swagger-ui.html

訪問以後的效果圖以下：json

訪問效果圖

點擊具體的接口展開詳情，效果圖以下：後端

新增人員接口

在/userInfo/selectById 接口中輸入相關參數，點擊Try it out 按鈕查看接口的返回值，以下：api

{
  "success": true,
  "msg": "成功",
  "data": {
    "id": 1,
    "userNo": "admin",
    "userName": "管理員",
    "spellName": "guanliyuan",
    "password": "123",
    "userPhone": "18681558780",
    "userGender": 0,
    "createTime": "2017-06-27 01:56:28",
    "updateTime": "2017-07-26 15:56:05"
  }
}
