dawdler-client-api-generator

模块介绍

基于java源码doc生成兼容swagger-ui的OpenAPI 3.0的json工具,对源代码零侵入,上手简单,生成效率高,使用非常方便.

1. pom中引入依赖

 <groupId>club.dawdler</groupId>
 <artifactId>dawdler-client-api-generator</artifactId>

2. dawdler-web-api.yml配置文件说明

例:

version: 1.0
title: "演示服务"
description: "用于演示的文档"
contact:
 name: "jackson.song"
 email: "suxuan696@gmail.com"
 url: "https://github.com/srchen1987"
swagger: "2.0"
host: "localhost"
basePath: "/"
scanPath:
 - "/home/srchen/github/api-demo"
outPath: "/home/srchen/github/api-demo/demo-api.json"

说明：

名称 说明
version 版本号
title 标题
description 描述
contact 联系人 相关信息
swagger swagger版本号
host api地址,例如: 192.168.1.55:8080
basePath web的basePath
scanPath 扫描路径,Controller或实体对象(数组结构)
outPath 输出json的路径

3. 使用方法

3.1 基础配置

参考dawdler-web-api.yml文件进行配置,确保scanPath配置正确.

3.2 必要条件

scanPath配置一定要配置正确,确保路径下有Controller(必须使用@Controller注解的才会生效).

方法返回值需要使用@ResponseBody标注,如果非基础类型或String或BigDecimal则需要在scanPath内才会生效.

方法参数值使用@RequestBody标注的对象需要在scanPath内才会生效.

返回的对象需要有@ResponseBody标注,如果不支持的类型则不会解析,比如Map.

3.3 生成api文件

java -jar dawdler-client-api-generator-0.0.5-jdk1.8-RELEASES.jar /home/srchen/github/api-demo/dawdler-web-api.yml

运行后会生成demo-api.json(outPath配置的路径).

3.4 启动swagger-ui

拉取docker镜像

docker pull swaggerapi/swagger-ui

启动

docker run -p 80:8080 -e BASE_URL=/swagger -e SWAGGER_JSON=/foo/demo-api.json -v /home/srchen/github/api-demo:/foo swaggerapi/swagger-ui

访问 http://localhost/swagger 既可使用.

4. 已支持javaDoc的Tag/注解/对象

4.1 JavaDoc的Tag

  1. 用于类或方法的描述信息,支持放在类上或方法上.(同时支持javadoc标准 方法上注释,可不编写@Description)

  2. @param 用于方法参数对应的注释信息,只支持方法上.

注释上有 @param userId 用户ID, 方法参数列表中的userId就会被备注为名字.

例如:

 /**
  * 
 * @Title: get 
 * @author jackson.song 
 * 根据用户ID查询用户
 * @param userId 用户ID
 *
  */
 @RequestMapping(value = "/user/get",method = RequestMethod.GET)
 @ResponseBody
 public User get(String userId){
  return null;
 }
4.2 dawdler-client-plug的注解

  1. @Controller 标识一个类为Controller,只有此标识才会被扫描生成文档,用于类上.

  2. @RequestMapping 标识设置请求api的path,只有此标识才会被扫描生成文档,支持设置类上和方法上.

  3. @RequestParam 指定request请求参数名的注解,可以用搭配@param来做注释,注意RequestParam中的value需要与@param的值对应才生效.

  4. @PathVariable 获取pathVariable的变量,用于方法参数列表中,可以用搭配@param来做注释.

  5. @RequestHeader 获取head中的值,用于方法参数列表中,可以搭配@param来做注释.

  6. @RequestBody 标识一个对象通过http body方式传入.

  7. @ResponseBody 标识返回对象.

4.3 方法参数列表支持的对象类型(dawdler-client-plug中支持的对象)

  1. UploadFile 用于上传文件时使用的对象,可以搭配@param来做注释.

  2. java8大基础类型 用于获取http请求参数,可以搭配@param来做注释.

  3. String类型 用于获取http请求参数,可以搭配@param来做注释.

  4. BigDecimal 用于获取http请求参数,可以搭配@param来做注释.

  5. 自定义对象(通过@RequestBody标识时需要http body,如果没有@RequestBody标识,则自定义对象的属性会作为http param参数) 注释只支持在自定义对象中加入注解,注释采用/注释/ 例如:

public class User {
 /**
  * 用户ID
  */
 private Integer userId;
 /**
  * 用户名
  */
 private String userName;
 /**
  * 地址
  */
 private String address;

 public Integer getUserId() {
  return userId;
 }
 public void setUserId(Integer userId) {
  this.userId = userId;
 }
 public String getUserName() {
  return userName;
 }
 public void setUserName(String userName) {
  this.userName = userName;
 }
 public String getAddress() {
  return address;
 }
 public void setAddress(String address) {
  this.address = address;
 }
}

5. 返回数据类型

  1. 8大基础类型及数组

  2. String类型及数组

  3. BigDecimal及数组

  4. List<类型>/Set<类型>/Collection<类型>/Vector<类型>

  5. 自定义类,支持泛型.

6. 演示demo

DemoController是Controller的一个例子.

package com.anywide.dawdler.demo.api.controller;

import java.util.List;

import com.anywide.dawdler.clientplug.annotation.Controller;
import com.anywide.dawdler.clientplug.annotation.PathVariable;
import com.anywide.dawdler.clientplug.annotation.RequestBody;

  **/

 @RequestMapping(value = "/head/test", method = RequestMethod.GET)
 public String headTest(@RequestHeader("token") String token) {
  return token;
 }

 /**

  * 
  **/

 @RequestMapping(value = "/testFileUpload", method = RequestMethod.POST)
 @ResponseBody
 public boolean testFileUpload(Integer id, UploadFile[] file) {
  return false;
 }

 /**
  * 
  * @author jackson.song
  * 根据User实体对象的属性生成对应的Http param参数
  *
  */
 @RequestMapping(value = "/createUser", method = RequestMethod.POST)
 @ResponseBody
 public User createUser(User user) {
  return null;
 }

}

User 实体类

package com.anywide.dawdler.demo.api.entity;

/**
 * 
* @ClassName: User 
* @author jackson.song
*/
public class User {
 /**
  * 用户ID
  */
 private Integer userId;
 
 /**
  * 用户名
  */
 private String userName;
 
 /**
  * 地址
  */
 private String address;

 public Integer getUserId() {
  return userId;
 }

 public void setUserId(Integer userId) {
  this.userId = userId;
 }

 public String getUserName() {
  return userName;
 }

 public void setUserName(String userName) {
  this.userName = userName;
 }

 public String getAddress() {
  return address;
 }

 public void setAddress(String address) {
  this.address = address;
 }

}

UserBank实体类

public class UserBank {

 /** 银行卡ID */
 private int cardid;
 /** userid */
 private int userid;
 /** 银行类型id */
 private int bankid;
 /** 开户行 */
 private String openBank;
 /** 持卡人姓名 */
 private String username;
 /** 银行卡号 */

 private int creator;
 
 public int getCardid() {
  return cardid;
 }
 public void setCardid(int cardid) {
  this.cardid = cardid;
 }
 public int getUserid() {
  return userid;
 }
 public void setUserid(int userid) {
  this.userid = userid;

package com.anywide.dawdler.demo.api;

public class BaseResult<T, S> {

 private T data;

 private S dataS;

 /**
  * 信息
  */
 private String message;

 /**
  * 是否成功
  */
 private Boolean success;

 public S getDataS() {
  return dataS;
 }

 public void setDataS(S dataS) {
  this.dataS = dataS;
 }

  return data;
 }

 public void setData(T data) {
  this.data = data;
 }

 public String getMessage() {
  return message;
 }

 public void setMessage(String message) {
  this.message = message;
 }

 public Boolean getSuccess() {
  return success;
 }

 public void setSuccess(Boolean success) {
  this.success = success;
 }

}

InnerResult 为了测试多层泛型建的临时测试类

package com.anywide.dawdler.demo.api;

import java.util.List;

import com.anywide.dawdler.demo.api.entity.UserBank;

public class InnerResult<F> {
 private F datas;
 /**
  * 状态
  */
 private int status;
 private List<UserBank> userBanks;

 public int getStatus() {
  return status;
 }

 public void setStatus(int status) {
  this.status = status;
 }

 public F getDatas() {
  return datas;
 }

 public void setDatas(F datas) {
  this.datas = datas;
 }

 public List<UserBank> getUserBanks() {
  return userBanks;
 }

 public void setUserBanks(List<UserBank> userBanks) {
  this.userBanks = userBanks;
 }
}
