java对接金蝶webapi
因为公司需要对接金蝶，对接之中踩了不少坑
所以总结一下
第一个问题，
金蝶不像我们命名会有什么规范，像java一般都是采用驼峰命名的方式
他们虽然也有，但是他们实体属性首字母居然是大写，我对接时用工具json一键生成实体类
提交过去，转jsonString，全会把首字母小写，这个时候只想骂人
com.alibaba
fastjson
1.2.47
辗转反侧就引用了fastjson
注意一定要是1.2.4以上的版本
@JSONField(name = "Creator")只得老老实实的把所有字段全部加上@JSONField注解，防止转json时，会自动转成首字母小写的字段
第二个问题，
然后又出现新的问题，提交可以提交了，发现，哎，怎么数据不一样啊，有一些数据金蝶会自己补充的数据怎么没有了，我后面也加上了这个字段还是不行，行吧，用金蝶自己端里面的测试工具提交数据，是没问题的，自己用java对接提交的数据是有问题的
人狠话不多，咱对json
对了十几遍，想办法把自己api提交的json和金蝶端里面的测试工具填数据生成的json做成一样的，一个不漏，还是不行，我怀疑人生了
好吧我写了一个json对比代码，进行了对比，简直就是一模一样，提交还是不行
好吧，我发现了一个可以对比json的网站，都丢上去，发现还是一样，这。。。。。
后来我发现了一个致命问题，金蝶的json难道还有顺序？
通过key来获取值,也要顺序？(如果有知情的朋友，不妨解一下惑)
像我object-c，java，js，as3，c
我取json，都是通过key来取的啊
-----回归
@JSONField(name = "Creator",ordinal = 1)于是我就加上了这个
为了保险我还加上了一句
JSONObject jsonObject=new JSONObject(true);终于把顺序也调的和金蝶的一模一样，提交果然没问题了
文档里也不说一下，搞得我怀疑了人生
好了我把提交到金蝶的java工具类放出来

这里例子里面只展示查询这一个例子，其它功能都测试正常，但是要请求正常的入参，注意一下，金蝶的入参不是有点坑是很坑
