京东jos对接爬坑过程

需求：获取京东商家的订单
环境：java,官方宙斯SDK
1.申请账号注册开发者创建应用参考官方文档注册
注意一点是回调页面url：地址为用户访问应用的地址，当用户访问您的应用时，jos会把相关授权参数通过这个回调地址传给您；这个回调url只是在获取商家授权时需要用到，如果不是后台方法获取的话，填www.baidu.com就好。
2.获取appKey，appSecret，accessToken,下载SDK
感谢前辈提供帮助


在控制台应用管理中，从应用证书中可以找到appKey，appSecret;
点击SDK下载，获得SDK;

在应用基本信息中点击测试;

用商家账号登陆，点击授权后，跳转到百度首页，在地址栏中可看到后面的带参?code=48OtVB，保存起来;
拼接https://oauth.jd.com/oauth/token?grant_type=authorization_code&client_id=你的appkey&redirect_uri=http:www.baidu.com&code=48OtVB&state=1212&client_secret=你的appSecret
用浏览器打开;
{
“access_token”: “xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”,
“code”: 0,
“expires_in”: 86390,
“refresh_token”: “xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”,
“time”: “1516248547902”,
“token_type”: “bearer”,
“uid”: “524625331”,
“user_nick”: “jd abcd”
}
注意，测试的accress_token的时效性只有24小时,之后需要重新获取一次
3.后台获取订单
官方java示例：

public JdClient client=new DefaultJdClient(SERVER_URL,accessToken,appKey,appSecret);

OrderSearchRequest request=new OrderSearchRequest();

request.setStartDate( "jingdong" );
request.setEndDate( "jingdong" );
request.setOrderState( "jingdong" );
request.setPage( "jingdong" );
request.setPageSize( "jingdong" );
request.setOptionalFields( "jingdong" );
request.setSortType( "jingdong" );
request.setDateType( "jingdong" );

OrderSearchResponse response=client.execute(request);

项目中引入宙斯SDK后，测试了下，会报错
只有open-api-sdk-2.0会报错java.lang.NoSuchMethodError，还得另外的jar包。
这里就超级坑了，翻遍了官方文档，百度了很久，终于凑齐了jar包
jar下载

最后就是response的解析了，jos使用的是分页查询，注意是把Page理解为页码，官方描述容易误导，说一次最多可查1000个订单，最大PageSize为100，最大Page为50，容易理解为一次查询Page*PageSize个订单，其实是结果以PageSize分页，返回的只有第Page页的订单。

结尾贴一下自己的代码，大神请无视
