当在SpringBoot中配置Wicket时，我有一个简单的Wicket 7.4.0项目。我有@Service spring bean想要注入Wicket页面。现在，当通过mountPage（..）命令挂载Wicket页面时@Inject注释适用于wicket页面。但@Inject不适用于由AnnotatedMountScanner（）安装的wicket页面。这里有什么想法吗？请参阅下面的代码段。
@Override
public void init() {
super.init();
getComponentInstantiationListeners().add(
new SpringComponentInjector(this, applicationContext));
new AnnotatedMountScanner().scanPackage("com").mount(this);
mountPage("/x", PageAbout.class);
getMarkupSettings().setDefaultMarkupEncoding("utf-8");
}
