/**
 * json 字符串结果转换成bean.
 * 
 * 
 * 场景:
 * 比如doku 支付方式, 在GeneratePayCode流程中,返回的结果json字符串是
 * 
 * 
 *  * 原始结果:
   {
   "res_pay_code":"00001014",
   "res_pairing_code":"280618203138833110",
   "res_response_msg":"SUCCESS",
   "res_payment_code":"5511",
   "res_response_code":"0000",
   "res_session_id":"888"
   }
 * 
 *
 * 此时有java bean
 * 
 *  * public class DokuGeneratePayCodeResultCommand implements GeneratePayCodeResultCommand{
 * 
 *     private String resPayCode;
 * 
 *     private String resPairingCode;
 * 
 *     private String resResponseMsg;
 * 
 *     private String resPaymentCode;
 * 
 *     private String resResponseCode;
 * 
 *     private String resSessionId;
 * 
 *     //setter getter省略
 * }
 * 
 * 
 * 返回的json字符串属性带有下划线, 而javabean 是标准的驼峰命名,你可以使用以下配置:
 * 
 * {@code

    
       
           
                
                      
                
            
        
     

}
