以下是我的两个类

/**
	 * 83.销售单据明细
	 */
	@Many(target = S_saledetail.class, field = "billid")
	private List<S_saledetail> s_saledetail;
	
	public List<S_saledetail> getS_saledetail() {
		return s_saledetail;
	}
	public void setS_saledetail(List<S_saledetail> s_saledetail) {
		this.s_saledetail = s_saledetail;
	}

第二个

@Table("s_saledetail")
public class S_saledetail {	
	/**
	 * 1.
	 */
	@Column("billid")
	private Integer billid;

get set方法都有设置. 这是为啥呀

S_sale sale;
执行dao().insert(sale)时报错了

额,必须是主键啊...

Many还有个key属性

还是这个问题,我用了key但还是报错,不知道自己写的对不对

	/**
	 * 80.从表s_orderdetail
	 */
	@Many(target = S_saledetail.class,  key = "billid", field = "billid")
	private List<S_orderdetail> s_orderdetail;

这个billid 不是主键

这个billid 在 主表中不是主键 但还是报这个错误

恩?两边的属性名都是一样的?

嗯嗯 是一样的,实在不行我改下bean吧.

Invalid @Many(field=billpid) 's_orderdetail' : class com.bsdkj.bms.modules.mvc.bean.suda.sale.S_order<=>class com.bsdkj.bms.modules.mvc.bean.suda.sale.S_saledetail

改bean好像不行,数据库的人就把这两个字段写成一样的了.

对应的是@Column("")中的字段名称 那个没法改了.

是属性名称,不是字段名

另外,nutz版本是多少?用1.r.60 o哦
