带有 AnnotationConfigApplicationContext 的 java.lang.IllegalArgumentException

Question

我试图按照链接https://www.tutorialspoint.com/spring/spring_java_based_configuration.htm 中的@Configuration & @Bean Annotations 部分下的示例进行操作，但出现以下异常：

Dec 31, 2018 2:59:33 PM org.springframework.context.support.AbstractApplicationContext prepareRefresh
INFO: Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@2dda6444: startup date [Mon Dec 31 14:59:33 EST 2018]; root of context hierarchy

我使用的是 java 1.8，spring 3.2.1。 谢谢你的帮助。

package com.tutorialspoint;
import org.springframework.context.annotation.*;

@Configuration
public class HelloWorldConfig {
   @Bean 
   public HelloWorld helloWorld(){
      return new HelloWorld();
   }
}

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);
   }
}

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.*;

public class MainApp {
   public static void main(String[] args) {
      ApplicationContext ctx = 
         new AnnotationConfigApplicationContext(HelloWorldConfig.class);

      HelloWorld helloWorld = ctx.getBean(HelloWorld.class);
      helloWorld.setMessage("Hello World!");
      helloWorld.getMessage();
   }
}

它在 MainApp.java 的 new AnnotationConfigApplicationContext(HelloWorldConfig.class) 上失败了

如果可以，请使用教程中指定的 Spring 4.1.6。

我使用spring-framework-3.2.1.RELEASE-dist.zip重现了您的错误，但 Hello World 应用程序使用spring-framework-4.1.6.RELEASE-dist.zip对我来说运行良好。
