SpringMVC的接口，接收json數據返回json數據並且解析為List對象集合

請求參數實體類

package com.lifuyi.entity;
/** * 請求參數**重點內容** */
public class RequestPram {
    //訂單號
    private String orderNum;
    //缸號
    private String batchNum;
    //該缸號的具體生產進度
    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 + "]";
    }
}

響應參數實體類

package com.lifuyi.entity;
/** * 響應參數 */
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 + "]";
    }


}
