表单中的文本框名为deliveryshanghai
JAVAEAN中声明 float deliveryshanghai ;

public void setDeliveryshanghai(String deliveryshanghai) {
this.deliveryshanghai = Float.valueOf(deliveryshanghai);
}


这样也不行：
public void setDeliveryshanghai(String deliveryshanghai) {
this.deliveryshanghai = Float.parseFloat(deliveryshanghai);
}
