1.1、如下图我们都能够发现这种封装的问题
代码繁杂、充斥了很多重复性代码返回值单一无法拿到对应的Java Bean对象及List对象集合实际场景中会对接大量第三方的OPEN API下述方法的扩展性差 1.2、简洁调用方式演示
本文基于上述问题通过设计模式、泛型、JSON工具类的方式进行了封装得到了下述更方便、更简洁的http请求调用方式
Entity params new Entity();
params.setUrl(/common/postJson);MapString, Object map new HashMap();
map.put(userId, 13277887788);
map.put(companyId, 87037827534cf);
params.setParams(map);// 返回对象集合
ListAppEntity appEntity thirdHttpProcessorFactory.doGetReturnList(ThirdSystemEnum.ION, params, AppEntity.class);
// 返回String类型
String result thirdHttpProcessorFactory.doGetReturnBean(ThirdSystemEnum.ION, params, String.class);
// 返回指定的对象
AppEntity appEntity thirdHttpProcessorFactory.doGetReturnBean(ThirdSystemEnum.ION, params, AppEntity.class);
1.3、 目录结构 2、引入的maven仓库 dependencygroupIdcom.fasterxml.jackson.core/groupIdartifactIdjackson-databind/artifactIdversion2.14.2/version
/dependency

/dependencyThirdHttpProcessorFactory存储不同三方平台的处理期ThirdHttpProcessor定义通用的接口AbstractThirdHttpProcessor定义公共的处理逻辑IonHttpProcessor定义各对接平台的差异性逻辑AppEntity返回值Entity入参ThirdSystemEnum定义三方平台的枚举
3、代码实现
3.1、获取不同第三方处理器的工厂ThirdHttpProcessorFactory

}3.3、通用逻辑处理的抽象类AbstractThirdHttpProcessor
如在通过http client发起HTTP请求时除了请求头requestHeader、请求入参requestBody不同其他逻辑都是一样的则可以进行公共代码的抽取如果存在特殊的逻辑处理则可以在子类中重写父类的方法

3.4、第三方非通用逻辑处理类IonHttpProcessor
比如此处对接的xx公司需要进行access_token获取及验证然后将access_token放在请求头中
package com.ionrocking.platform.tripartite.impl;import cn.hutool.core.lang.TypeReference;
import cn.hutool.core.text.CharSequenceUtil;
import cn.hutool.http.HttpUtil;
import cn.hutool.json.JSONUtil;
import com.ionrocking.platform.tripartite.AbstractThirdHttpProcessor;
import com.ionrocking.platform.tripartite.entity.Entity;
import com.ionrocking.platform.tripartite.entity.IonResponse;
import com.ionrocking.platform.tripartite.enums.ThirdSystemEnum;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;import java.util.HashMap;
import java.util.Map;/*** author ke* Date 2023/10/27*/
Slf4j
Component
public class IonHttpProcessor extends AbstractThirdHttpProcessor {private String accessTokenUrl /token/getAccessToken;private static final String ACCESS_TOKEN_KEY access_token;Overridepublic MapString, String constructRequestHead(Entity entity) {MapString, String header new HashMap(2);MapString, Object params new HashMap(4);params.put(appId, sysNacosConfig.getIonRequestAppId());params.put(appSecret, sysNacosConfig.getIonRequestAppSecret());String result HttpUtil.get(sysNacosConfig.getIonRequestUrl() accessTokenUrl, params);if (CharSequenceUtil.isEmpty(result)) {return null;}TypeReferenceIonResponseMapString, Object typeRef new TypeReferenceIonResponseMapString, Object() {};IonResponseMapString, Object response JSONUtil.toBean(result, typeRef, false);if (CODE response.getCode() null ! response.getData()) {if (response.getData().containsKey(ACCESS_TOKEN_KEY)) {header.put(ACCESS_TOKEN_KEY, response.getData().get(ACCESS_TOKEN_KEY).toString());}}return header;}Overridepublic ThirdSystemEnum getType() {return ThirdSystemEnum.ION;}
}3.5、枚举类ThirdSystemEnum
区分不同的平台根据枚举获取不同的实现类
package com.ionrocking.platform.tripartite.enums;import org.apache.commons.lang3.StringUtils;/*** author ke* Date 2023/10/27*/
public enum ThirdSystemEnum {/*** XX科技公司*/ION(ion, xx科技);private final String code;private final String name;public String getName() {return this.name;}public String getCode() {return this.code;}ThirdSystemEnum(String code, String name) {this.code code;this.name name;}public static ThirdSystemEnum getByCode(String code) {if (StringUtils.isEmpty(code)) {return null;}for (ThirdSystemEnum codeEnum : values()) {if (code.equals(codeEnum.getCode())) {return codeEnum;}}return null;}
}3.6、第三方返回格式对象IonResponse
package com.ionrocking.platform.tripartite.entity;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;/*** author ke* Date 2023/10/27*/
Data
NoArgsConstructor
AllArgsConstructor
public class IonResponseT implements Serializable {private static final long serialVersionUID -8741972144218822267L;private int code;/*** 消息*/private String msg;/*** 数据*/private T data;/*** 总记录数*/private long total;
}
3.7、处理器入参对象Entity
此处定义请求的URL和请求的参数
package com.ionrocking.platform.tripartite.entity;import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;
import java.util.Map;/*** author ke* Date 2023/10/27*/
Data
Builder
NoArgsConstructor
AllArgsConstructor
public class Entity implements Serializable {private static final long serialVersionUID -6083780287057302816L;private String url;/*** 参数*/private MapString, Object params;
}
3.8、第三方接口返回值对象AppEntity
package com.ionrocking.platform.tripartite.entity;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;import javax.validation.constraints.NotBlank;/*** author ke* Date 2023/10/26*/Data
Accessors(chain true)
NoArgsConstructor
AllArgsConstructor
public class AppEntity {private long id;private String appId;NotBlank(message 应用名称不能为空)private String appName;private String appSecret;private String accessToken;private Integer isFlag;
}3.9、Nacos配置
Nacos中一般存放一些第三方的请求域名、鉴权的appId、appSecret等
tripartite-platform:ion:request:url: http://localhost:8080/api/appId: YodeqWwpappSecret: 87037827534cf848a570fae3c93a2469fa0262935af531dddfe7a52ae7f98f41package com.ionrocking.platform.config;import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;/*** nacos配置信息* author ke* Date 2023/9/20*/
Component
public class SysNacosConfig {Value(${upload.path})private String uploadPath;Value(${tripartite-platform.ion.request.url})private String ionRequestUrl;Value(${tripartite-platform.ion.request.appId})private String ionRequestAppId;Value(${tripartite-platform.ion.request.appSecret})private String ionRequestAppSecret;public String getUploadPath() {return uploadPath;}public String getIonRequestUrl() {return ionRequestUrl;}public String getIonRequestAppId() {return ionRequestAppId;}public String getIonRequestAppSecret() {return ionRequestAppSecret;}
}测试
RestController
RequestMapping(/test)
public class Test {Resourceprivate SysNacosConfig sysNacosConfig;Resourceprivate ThirdHttpProcessorFactory thirdHttpProcessorFactory;ResponseBodyRequestMapping(value /get)public AjaxResult get() throws Exception extends BaseController {Entity params new Entity();params.setUrl(/common/get);String result thirdHttpProcessorFactory.doGetReturnBean(ThirdSystemEnum.ION, params, String.class);return AjaxResult.success(result);}ResponseBodyRequestMapping(value /list)public AjaxResult list() throws Exception {Entity params new Entity();params.setUrl(/common/list);ListAppEntity appEntity thirdHttpProcessorFactory.doGetReturnList(ThirdSystemEnum.ION, params, AppEntity.class);return AjaxResult.success(appEntity);}ResponseBodyRequestMapping(value /postJson)public AjaxResult postJson() throws Exception {Entity params new Entity();params.setUrl(/common/postJson);MapString, Object map new HashMap();map.put(appId, YodeqWwp);map.put(appSecret, 87037827534cf848a570fae3c93a2469fa0262935af531dddfe7a52ae7f98f41);params.setParams(map);ListAppEntity list thirdHttpProcessorFactory.doPostJsonReturnList(ThirdSystemEnum.ION, params, AppEntity.class);return AjaxResult.success(list);}
}
