VLA、世界模型与端到端在智驾中的本质关系与工程落地世界模型并非3D重建，而是对环境状态转移函数的可微分建模；VLA不是视觉+语言+动作的简单拼接，核心在于跨模态语义对齐。二者共同支撑具身智能系统实现从感知到行动的闭环推演，其技术价值体现在长尾场景泛化能力提升与决策延迟降低。在自动驾驶领域，真实量产方案均采用VLA架构作为多模态感知基础，嵌入轻量级世界模型以支持反事实轨迹推演，并通过WA硬件封装保障实时性，最终由端到端控制层完成像素到扭矩的语义贯通。这种混合架构已成L2+/L3智驾系统的工程共识。阅读详情

SpringAop3.xml的配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans

default-autowire="byName">

<bean id="eatHepler" class="com.o0kiss0o.springaop.EatHelper" />
<bean id="human" class="com.o0kiss0o.springaop.Human" />
<aop:aspectj-autoproxy/>
<aop:config proxy-target-class="true">
<aop:aspect ref="eatHelper">
<aop:before method="before" pointcut="execution(* *.eatSomething(..))"/>
<aop:after method="afterReturning" pointcut="execution(* *.eatSomething(..))"/>
</aop:aspect>
</aop:config>
</beans>

测试的方法如下
package com.o0kiss0o.springaop;

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

public class Test {
public static void main(String[] args){
ApplicationContext container = new ClassPathXmlApplicationContext("SpringAop3.xml");
//Eatable et = (Eatable)container.getBean("humanProxy");//对应SpringAop1.xml
Eatable et = (Eatable)container.getBean("human");
et.eatSomething("apple");
}
}

EatHelper 的类如下
package com.o0kiss0o.springaop;

import java.lang.reflect.Method;

import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;

public class EatHelper implements MethodBeforeAdvice,AfterReturningAdvice{

public EatHelper(){

}

@Override
public void afterReturning(Object arg0, Method arg1, Object[] arg2,
Object arg3) throws Throwable {
// TODO Auto-generated method stub
System.out.println("After eat something ----");
}

@Override
public void before(Method arg0, Object[] arg1, Object arg2)
throws Throwable {
// TODO Auto-generated method stub
System.out.println("Before eat something ----");
}

}

但是执行的时候报了这个错误
