请求参数实体类

package com.lifuyi.entity;
    /** * 请求参数**重点内容** */
    public class RequestPram { 
        //订单号
        private String orderNum;
        //缸号
        private String batchNum;
        //该缸号的具体生产进度
        private String node;
        public String getOrderNum() {
            return orderNum;
        }
        public void setOrderNum(String orderNum) {
            this.orderNum = orderNum;
        }
        public String getBatchNum() {
            return batchNum;
        }
        public void setBatchNum(String batchNum) {
            this.batchNum = batchNum;
        }
        public String getNode() {
            return node;
        }
        public void setNode(String node) {
            this.node = node;
        }
        @Override
        public String toString() {
            return "RequestPram [orderNum=" + orderNum + ", batchNum=" + batchNum + ", node=" + node + "]";
        }
    }

**响应参数实体类**

package com.lifuyi.entity;
    /** * 响应参数 */
    public class ResponsePram { 
        private String resultCode;
        private String desc;
    
        public ResponsePram() {
            super();
        }
        public ResponsePram( String desc,String resultCode) {
            super();
            this.desc = desc;
            this.resultCode = resultCode;
    
        }
        public String getResultCode() {
            return resultCode;
        }
        public void setResultCode(String resultCode) {
            this.resultCode = resultCode;
        }
        public String getDesc() {
            return desc;
        }
        public void setDesc(String desc) {
            this.desc = desc;
        }
        @Override
        public String toString() {
            return "ResponsePrams [resultCode=" + resultCode + ", desc=" + desc + "]";
        }
    
    
    }
