Question

作为一个HelloWorld示例，在我的spring Beans.xml文件中，我有：

<?xml version = "1.0" encoding = "UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

   <bean id = "helloWorld" class = "com.tutorialspoint.HelloWorld">
      <property name = "message" value = "Hello World!"/>
   </bean>

</beans>

主文件：

package com.tutorialspoint;

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

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

类文件：

package com.tutorialspoint;

public class HelloWorld {
   private String message;

   public void setMessage(String message){
      this.message  = message;
   }
   public void getMessage(){
      System.out.println("Your Message : " + message);
   }
}

The error seems like this:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloWorld' defined in class path resource [Beans.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.tutorialspoint.HelloWorld]: Is the constructor accessible?; nested exception is java.lang.IllegalAccessException: class org.springframework.beans.BeanUtils (in module spring.beans) cannot access class com.tutorialspoint.HelloWorld (in module HelloSpring) because module HelloSpring does not export com.tutorialspoint to module spring.beans

此网站上的其他人也遇到了同样的问题，我已经进行了研究。但是，我尝试了所有提供的答案，但没有一个解决了我的问题。我使用了内部路径的多个版本，并且在Beans.xml的第一行上方没有空行。这是什么问题？
