Java 在Eclipse中设置Spring-上下文初始化失败

我正在尝试设置Eclipse（作为Java、Eclipse和Spring的新手），当我尝试运行一个简单的HelloWorld.Java时，我在控制台中遇到了这个错误

我在MainApp.java中的代码

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {
   public static void main(String[] args) {
      @SuppressWarnings("resource")
    ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
      obj.getMessage();
   }
}

如果您向我们提供java代码，将会很有帮助。 但是，基于这些错误，我相信在安装程序时有一个损坏的文件。 确保您使用的计算机没有任何限制，然后重新安装该程序 用这个来代替我。

希望有帮助

好吧，在做了更多的修改之后，我找到了问题所在

1） Spring库必须手动添加到类路径下，而不是modulepath下

2） xml文件必须直接放在src文件夹中，而不是放在包含java文件的包中

不，不是。这是因为Java 9中引入了模块系统。我忘记了这一点。谢谢你们，我刚从市场上重新安装，它运行良好（还因为我找不到如何处理这些更改的模块访问权限）。首先，我想推荐tutorialpoint的教程。它们中的大多数质量都很可疑。坚持使用官方教程或知名来源。其次，本教程是用Java8（或更早版本）设计的，您使用的是Java9或更高版本。您可能需要调整模块访问权限，但我无法马上告诉您应该如何进行调整。

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {
   public static void main(String[] args) {
      @SuppressWarnings("resource")
    ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
      obj.getMessage();
   }
}
