嗨,大家好我用hibernate和spring创建了一个简单的web应用程序,我想实现一个包含crud操作的抽象类,但是我有这个错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'clientService' defined in class path resource [applicationContext.xml]:
Cannot resolve reference to bean 'clientDao' while setting bean property 'clientDao'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:

根据输入,我可能需要要么int[],int[][],int[][][][][][],或其他任何东西.(对于上下文,我正在尝试为元胞自动机构建一个N维网格,其中N作为参数传递.)
我没有任何代码,因为我不知道如何去做; 我怀疑只使用数组是不可能的.任何帮助或替代解决方案,将不胜感激.
我已经研究了一段时间,但似乎无法弄清楚如何将项添加到ArrayList.我想将grocItem(应该是来自for循环的用户输入的7个grocItems)添加到grocList的ArrayList中:
public class ItemData{
public ItemData(String name, double cost, int priority){
Main.(ArrayList grocList).add(grocItem);
// Main.groclist.add(grocItem);
}
