Question

我正在尝试使用类路径中的Java加载我的spring context.xml文件。我的context.xml文件位于src/main/resources。

public static void main(String[] args) {
    ClassPathXmlApplicationContext context = null;
    try {
        context = new ClassPathXmlApplicationContext("classpath:context.xml");
        context.registerShutdownHook();
    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        if (context != null) {
            context.close();
        }
    }
}

当我在日食中运行时，上面的代码工作正常。但是只要我通过右键单击项目将其打包到一个可运行的jar中并选择export作为一个可运行的jar然后从ubuntu机器运行jar作为 -

java -jar test.jar

然后我得到以下异常 -

我有什么遗失的吗？

您可能没有在jar中的src/main/resources中包含资源。我不相信Maven插件涉及Eclipse的Jar Export实用程序。

如何在Java中从classpath加载“context.xml”？
