我刚开始学习Spring框架。我正在学习构造函数的 Spring 依赖注入，并在尝试运行代码时遇到了此错误。请帮助我解决此错误并解释导致此错误发生的原因。谢谢。
这是我的代码：
ActiveMQMessage.java
package com.infotech;
public class ActiveMQMessage {
public void sendMessage() {
System.out.println("Send message via ActiveMQMessage..");
}
}
沟通.java
package com.infotech;
public class Communication {
private ActiveMQMessage activeMQMessage;
public Communication(ActiveMQMessage activeMQMessage) {
super();
this.activeMQMessage = activeMQMessage;
}
public void communicate() {
activeMQMessage.sendMessage();
}
}
应用程序上下文.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="communication" class="com.infotech.Communication">
<constructor-arg name="activeMQMessage" ref="activeMQMessage"></constructor-arg>
</bean>
<bean id="activeMQMessage" class="com.infotech.ActiveMQMessage"></bean>
</beans>
主.java
package com.infotech;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) {
AbstractApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Communication communication = context.getBean("communication", Communication.class);
communication.communicate();
context.close();
}
}
这是错误：

我至少会尝试从<constructor-arg>中删除name=属性。如果只有一个可能匹配的构造函数，并且虽然您拥有的构造函数似乎应该有效，但错误消息似乎确实指示与名称解析相关的内容，则这不是绝对必要的。
com.spring.core 和 com.spring.asm jar 文件在项目中必须是不同的版本。 ASM jar 已经很长时间没有更新了，这就是为什么您需要降级核心 JAR 文件的原因。
