Spring MVC表单提交多个对象

动态添加行时有可能提交的时候出现空值，到时候只要判断其中的字段是否为空，然后new一个新集合，把不为空的对象放进去就可以了。

1、

public class DeliverApplyDetailListForm {
    private List<DeliverApplyDetail> deliverApplyDetail;

    public List<DeliverApplyDetail> getDeliverApplyDetail() {
        return deliverApplyDetail;
    }

    public void setDeliverApplyDetail(List<DeliverApplyDetail> deliverApplyDetail) {
        this.deliverApplyDetail = deliverApplyDetail;
    }
    
}

2、

package cn.fenghuait.sale.model;

import java.math.BigDecimal;

public class DeliverApplyDetail {
    private String detailNo;

    private String productId;

    private Long productNeedNum;

    private BigDecimal realPrice;

    private BigDecimal ticketPrice;

    private BigDecimal totalRealPrice;

    private BigDecimal totalTicketPrice;

    private String applyNo;

    private String typeName;

    public String getDetailNo() {
        return detailNo;
    }

    public void setDetailNo(String detailNo) {
        this.detailNo = detailNo;
    }

    public String getProductId() {
        return productId;
    }

    public void setProductId(String productId) {
        this.productId = productId;
    }

    public Long getProductNeedNum() {
        return productNeedNum;
    }

    public void setProductNeedNum(Long productNeedNum) {
        this.productNeedNum = productNeedNum;
    }

    public BigDecimal getRealPrice() {
        return realPrice;
    }

    public void setRealPrice(BigDecimal realPrice) {
        this.realPrice = realPrice;
    }

    public BigDecimal getTicketPrice() {
        return ticketPrice;
    }

    public void setTicketPrice(BigDecimal ticketPrice) {
        this.ticketPrice = ticketPrice;
    }

    public BigDecimal getTotalRealPrice() {
        return totalRealPrice;
    }

    public void setTotalRealPrice(BigDecimal totalRealPrice) {
        this.totalRealPrice = totalRealPrice;
    }

    public BigDecimal getTotalTicketPrice() {
        return totalTicketPrice;
    }

    public void setTotalTicketPrice(BigDecimal totalTicketPrice) {
        this.totalTicketPrice = totalTicketPrice;
    }

    public String getApplyNo() {
        return applyNo;
    }

    public void setApplyNo(String applyNo) {
        this.applyNo = applyNo;
    }

    public String getTypeName() {
        return typeName;
    }

    @Override
    public String toString() {
        return "DeliverApplyDetail [detailNo=" + detailNo + ", productId="
                + productId + ", productNeedNum=" + productNeedNum
                + ", realPrice=" + realPrice + ", ticketPrice=" + ticketPrice
                + ", totalRealPrice=" + totalRealPrice + ", totalTicketPrice="
                + totalTicketPrice + ", applyNo=" + applyNo + ", typeName="
                + typeName + "]";
    }

    public void setTypeName(String typeName) {
        this.typeName = typeName;
    }
    
}

3、Controller

 @RequestMapping(value="/deliverSaleApply")
      @ResponseBody
      public Map<String, Object> deliverSaleApply(HttpServletRequest request,DeliverApplyDetailListForm deliverApplyDetails,DeliverApply deliverApply){

for(DeliverApplyDetail deliverApplyDeatail :deliverApplyDetails.getDeliverApplyDetail()){
                  deliverApplyDeatailService.insert(deliverApplyDeatail);
              }

}

4、jsp页面
