这样配置 还是不能自动生成中间表

    @ManyMany(target = App_product.class, relation = "app_prod_sale", from = "id", to = "id",key="id")
    private List<App_product> products;

@wendal 现在问题来了 那么 现在有个BUG 两张表的主键都是ID 中间表存两张表的字段 怎么设定

@wendal 创建记录如何插入中间表呢
莫非再创建一个一对多关联中间表？

@wendal 原谅小学生问题多 已经自己解决了

@At
    @Ok("json")
    @SLog(tag = "新建App_sale_activity", msg = "")
    public Object addDo(@Param("..") App_sale_activity appSaleActivity,
						@Param("prodId") String prodId, HttpServletRequest req) {
		try {
			if(prodId.indexOf(";") != -1){
				String[] prodArr = prodId.split(";");
				List<App_product> appProductList = appProductService.query(Cnd.where("id","in",prodArr));
				appSaleActivity.setProducts(appProductList);
				appSaleActivityService.insert(appSaleActivity);
				appSaleActivityService.dao().insertRelation(appSaleActivity,"products");
			}
			return Result.success("system.success");
		} catch (Exception e) {
			return Result.error("system.error");
		}
    }
