wicket @SpringBean无法创建bean

问题描述

我有一个关于Eclipse，Wicket，Spring，Hibernate的项目。除了以下内容之外，每件事情都是正常的：当我尝试

I have a project on Eclipse, Wicket, Spring, Hibernate. Every thing works normaly except : when I try

public class SortableContactDataProvider extends SortableDataProvider<User>
{
    @SpringBean
    private Service service;

    public Iterator<User> iterator(int first, int count)
    {
        //SortParam sp = getSort();
        return service.findAllUsers().subList(0, 15).iterator();
    }
...

服务变量是否为空？在我使用这个构造的任何其他地方，服务不是空的并且运行良好。请帮我解决这个问题。

the service variable is null? In any another places when I use this constuction "service" is not null and working well. Please help me to solve this problem.

推荐答案

@SpringBean只能在Component的任何Subclass中使用。

@SpringBean works only in any Subclass of Component.

您需要在构造函数中执行以下操作

You need to do the following in your Constructor

Wicket 1.4

Wicket 1.4

  InjectorHolder.getInjector().inject(this);

Wicket 1.5 +

Wicket 1.5+

  org.apache.wicket.injection.Injector.get().inject(this);
