平常我们对接第三方都是以json的数据进行数据交互的，这次第三方接口只支持form-data格式的表单数据，传json数据对方不支持，通过百度和尝试各种方案最终完美解决，后期再慢慢优化吧。还有一个问题，数据中包含中文的户，到第三方是乱码的，经过百度参考前辈的经验，完没解决addTextBody乱码问题。记录下工作中遇到的一个小问题！
请求通过httpClient上传文件

httpcomponent框架MultipartEntityBuilderaddTextBody中文乱码
//使用addPartStringBody代替addTextBody，解决中文乱码
//builder.addTextBody(entry.getKey(),entry.getValue());
