简介
本文接入得物开放平台,
本文关键词
得物开放平台
、得物SDK
、得物PUSH
、获取订单
、虚拟发货
实现步骤
1 引入依赖
在得物开放平台下载JDK,本文以得物JDK1.3.8.RELEASE为基础进行接入。
下载后有三个文件:
- open-sdk-java-1.3.8-okhttp.RELEASE.jar
- open-sdk-java-1.3.8-urlconnect.RELEASE.jar
- 得物开放平台Java版sdk使用说明v1.0.1.pdf
1.1 Maven导入依赖
我们将下载的文件放在项目根目录下的libs文件夹中。
pox.xml
配置,引入jdk
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.0</version>
</dependency>
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>3.8.1</version>
</dependency>
<dependency>
<groupId>open-sdk-java-1.3.8-okhttp</groupId>
<artifactId>open-sdk-java-1.3.8-okhttp</artifactId>
<version>1.3.8</version>
</dependency>
<dependency>
<groupId>open-sdk-java-1.3.8-urlconnect</groupId>
<artifactId>open-sdk-java-1.3.8-urlconnect</artifactId>
<version>1.3.8</version>
</dependency>
1.2 引入失败
引入后如果没成功,可以尝试使用以下命令。
# 注意文件路径不要有中文
mvn install:install-file -Dfile=.\libs\open-sdk-java-1.3.8-okhttp.RELEASE.jar -DgroupId=open-sdk-java-1.3.8-okhttp -DartifactId=open-sdk-java-1.3.8-okhttp -Dversion=1.3.8 -Dpackaging=jar
mvn install:install-file -Dfile=.\libs\open-sdk-java-1.3.8-urlconnect.RELEASE.jar -DgroupId=open-sdk-java-1.3.8-urlconnect -DartifactId=open-sdk-java-1.3.8-urlconnect -Dversion=1.3.8 -Dpackaging=jar
刷新Maven。
2 配置
在得物开放平台中 -> 控制台 -> 应用管理 -> 我的应用 -> 应用详情 -> 应用信息
即可查看应用证书,AppKey、App secret
2.1 配置公钥私钥
application-dev.yml
新增得物配置信息,其他环境一样配置
### 得物配置
dewu:
gatewayHost: https://openapi.dewu.com
appKey: xxx
secret: xxxx
2.2 配置类
用于绑定配置文件中的配置参数。
DewuProperties.java
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties("dewu")
public class DewuProperties {
private String gatewayHost;
private String appKey;
private String secret;
public String getGatewayHost() {
return gatewayHost;
}
public DewuProperties setGatewayHost(String gatewayHost) {
this.gatewayHost = gatewayHost;
return this;
}
public String getAppKey() {
return appKey;
}
public DewuProperties setAppKey(String appKey) {
this.appKey = appKey;
return this;
}
public String getSecret() {
return secret;
}
public DewuProperties setSecret(String secret) {
this.secret = secret;
return this;
}
}
2.3得物配置类
DewuConfig.java
-
DewuFactoryConfig
:方法在启动时设置全局变量
- gatewayHost(api调⽤⽹关)
- appKey(应⽤key)
- secret(应⽤秘钥)
- authHost(授权⽹ 关)
- connectTimeout(链接超时时间,默认15秒)
- readTimeout(读取超时时间,默认15 秒)
- accessToken(如果是⾃研商家,这个可以全局设置,如果是isv请在请求的request参数⾥设 置)
-
serviceExecutor
:方法创建一个用于进行异步处理的线程池执行器。
import com.dewu.sdk.base.BaseClient;
import com.dewu.sdk.base.constans.CommonConstants;
import com.dewu.sdk.factory.Factory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import javax.annotation.Resource;
import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;
@Configuration
@EnableAsync
public class DewuConfig {
@Resource
private DewuProperties dewuProperties;
@Bean("DewuFactoryConfig")
public void DewuFactoryConfig(){
System.out.println("注入得物配置");
BaseClient.Config config = new BaseClient.Config();
config.setGatewayHost(dewuProperties.getGatewayHost());
config.setAppKey(dewuProperties.getAppKey());
config.setSecret(dewuProperties.getSecret());
config.setProtocol(CommonConstants.HTTPS);
Factory.setOptions(config);
}
@Bean("sellerDeliveryExecutor")
public Executor serviceExecutor(){
ThreadPoolTaskExecutor executor =
new ThreadPoolTaskExecutor();
//核心线程数量:当前机器的核心数
executor.setCorePoolSize(
Runtime.getRuntime().availableProcessors());
//最大线程数
executor.setMaxPoolSize(
Runtime.getRuntime().availableProcessors()*2);
//队列大小
executor.setQueueCapacity(Integer.MAX_VALUE);
//线程池中的线程名前缀
executor.setThreadNamePrefix("sellerDeliveryService-");
//拒绝策略:由提交任务的线程来执行该任务
executor.setRejectedExecutionHandler(
new ThreadPoolExecutor.CallerRunsPolicy()
);
//执行初始化
executor.initialize();
return executor;
}
}
3 配置
在得物开放平台中 -> 控制台 -> 应用管理 -> 我的应用 -> 应用详情 -> 应用信息
即可查看应用证书,AppKey、App secret
3.1 新建接口接收得物回调
DewuController.java

private static final Logger log = LoggerFactory.getLogger(DewuController.class);
@Resource
private IDewuService iDewuService;
@Resource
private DewuProperties dewuProperties;
/**

* 建议采用异步的方式接收消息
* 来源:https://open.dewu.com/#/doc?id=1010000048&pid=1010525077&type=article
*/
@PostMapping("/receivePush")
public Map<String, Object> receivePush(@RequestBody ParamWrapper paramWrapper, @RequestHeader("sign") String sign, @RequestHeader("msg_type") String msgType) {
log.info("接收到push请求,sign:{}, msgType:{}, 参数:{}", sign, msgType, JSONUtil.toJsonStr(paramWrapper));
/*************** sign验证开始,可不作校验***************/
if (sign == null) {
throw new ServiceException("sign为空,非法请求");
}
// 正式环境
String appKey = dewuProperties.getAppKey(); // 自己的appKey
String appSecret = dewuProperties.getSecret(); // 自己的appSecret
String newSign = DeWuUtils.generateSign(appKey, appSecret, paramWrapper);
if (!newSign.equals(sign)) {
throw new ServiceException("sign验证不通过,非法请求");
}
/*************** sign验证结束 *************************/
// 参数解密
if (!StringUtils.isEmpty(paramWrapper.getMsg())) {
String msgContent = DeWuUtils.aesDecode(appSecret, paramWrapper.getMsg());
if (StringUtils.isEmpty(msgContent)) {
throw new ServiceException("消息解密失败");
}
log.info("解密后的信息:"+msgContent);
// 获取订单号
// 将JSON字符串转换为JSONObject
JSONObject jsonObject = new JSONObject(msgContent);
String orderNo = jsonObject.getStr("orderNo");
iDewuService.sellerDelivery(orderNo);
}
return DeWuUtils.respSuccess(paramWrapper.getUuid());
}
}
