Question

在我的“区域”春季应用中,我有这一方法将春季管理人员引入<>代码>WebApplication类别:

private void initManager() {
    ApplicationContext applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
    this.manager = (MyManager) applicationContext.getBean("manager");
}

我通常在<代码>in内设置内部错误网页。我的<代码>WebApplication等方法。有时我也用一些可读页:

public class MyApplication extends WebApplication {

    @Override
    protected void init() {
        IApplicationSettings applicationSettings = getApplicationSettings();
        applicationSettings.setInternalErrorPage(ErrorPage.class);
        mountBookmarkablePage("privacy", PrivacyPage.class);
    }

    //............
}

My WebPage classes usually depend on my manager class, for instance:

public class ErrorPage extends WebPage {

    public ErrorPage() {
        MyApplication application = (MyApplication) getApplication();
        add(new EmailLink(application.getManager().getMailSupport()));
    }
}

因此,我的<代码>WebApplication类别系指一个或多个网页,我的网页指的是WebApplication。这是一种循环依赖吗? 如果是,我如何能够避免?

Answer 1

我要说的是,这不是循环依赖,而是组合。

然而,我认为你总是能够向网页班级和汽车线路注入你的经理。

EDIT:

You may also need to enable spring annotations in applicationContext.xml as well and add some new dependencies if not already in classpath

see applicationContext.xml sample at this address and your will be pretty much similar except the scan package name. Update those values accordingly.

public class ErrorPage extends WebPage {

@Autowired
private MyManager myManager;

//setter getter methods as well
}
