啟動OSGI應用程序時找不到context.xml

Question

OSGI bundles的類路徑通常是META-INF文件夾。 “ spring-context.xml”文件位於META-INF下的spring文件夾中。 您可以在應用程序圖片中看到。 ClassPathXmlApplicationContext找不到此xml文件。 我認為問題是類路徑。 但是我沒有解決這個問題。 在我的應用程序中，我嘗試使用spring-dm配置休眠模式。 在構建應用程序時，我幫助了該網站 。

我在下面分享給HİbernateUtil.class：

public abstract class HibernateUtil {

    private SessionFactory sessionFactory;

    private SessionFactory buildSessionFactory() {
        try {
            if (this.sessionFactory == null) {
                ApplicationContext applicationContext = new ClassPathXmlApplicationContext("META-INF/spring/spring-context.xml");
                this.sessionFactory = (SessionFactory) applicationContext.getBean("sessionFactory");
            }

        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }

        return this.sessionFactory;
    }

    public Session newSession() {
        if (this.sessionFactory == null)
            buildSessionFactory();
        return (this.sessionFactory == null ? null : this.sessionFactory.openSession());
    }

}

我與spring-context.xml分享以下內容：

此圖片是應用程序文件夾：

我在下面分享到應用程序控制台輸出：

Nis 13, 2017 7:13:59 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh

Answer 1

您在build.properties中包含目錄META-INF。 據我所知，這意味着該jar內的路徑沒有META-INF部分。 您可以嘗試“ spring / spring-context.xml”嗎？

Answer 2

我更改了ApplicationContext行下面的代碼，可能我解決了這個問題。 但是應用程序並非沒有問題就開始：

ApplicationContext applicationContext = new FileSystemXmlApplicationContext("/Desktop/dictionary_project/tr.cc.ex.dict.kernel.model/META-INF/spring/spring-context.xml");

我共享新的控制台輸出：

Nis 13, 2017 2:19:03 PM org.springframework.context.support.AbstractApplicationContext prepareRefresh
INFO: Refreshing org.springframework.context.support.FileSystemXmlApplicationContext@5e474f1b: startup date [Thu Apr 13 14:19:03 EET 2017]; root of context hierarchy

Offending resource: file [/home/oem/Desktop/dictionary_project/tr.cc.ex.dict.kernel.model/META-INF/spring/spring-context.xml]

然后，我搜索此異常。 應用程序具有“ org.springframework.context”捆綁包。 但是我不明白為什么應用會拋出這個異常。
