Question

我试图使用maven并使用spring和hibernate来运行应用程序。我已经在互联网上搜索了一段时间，我认为我添加了适当的依赖项，但它不起作用。我使用netbeans，我建立项目等所以所有依赖项都被下载和包含。我得到了：java.lang.ClassNotFoundException: org.springframework.context.support.ClassPathXmlApplicationContext。有人对这个有任何想法吗？的pom.xml

    import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
    public static void main(String args[]) {

        ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("spring.xml");//here's the error

        System.out.println("Working!");

    }
}

Answer 1

尝试将maven依赖范围更改为compile。

Answer 2

问题在于依赖范围。 PROVIDED范围不允许maven在进行战争时捆绑依赖项。删除范围标记。
