在不在我的项目中的类上加载时间编织

我正在尝试使用 Spring 为我创建的项目中的几个类提供加载时间编织.当我调用一个不在我本地项目中的类时，我无法让它工作.

I'm trying to use Spring to provide load time weaving to several classes in a project I've created. I'm having trouble getting it to work when I call a class that is not within my local project.

我创建了一个名为 ExampleClass 的类，当我对其中的一个方法执行 @Around 时，我可以看到我对返回值所做的修改，但是当我尝试对 String 做同样的事情，我无法得到任何结果.

I created a class named ExampleClass and when I perform an @Around on a method in there, I can see the modifications I made to the return, however when I attempt to do the same to String I'm unable to get any results.

这是我的方面代码:

@Pointcut("call(* java.lang.String.*(..))")
public void cutString() {}

@Before("cutString()")
public void aroundString() throws Throwable {
    System.out.println("I Never See This");
}

这是我对该代码的调用:

Here's my call to that code:

public class Main {
    public static void main(String[] args) {
        new ClassPathXmlApplicationContext("classpath:my-context.xml");

        String string = new String("I Only See This");
        System.out.println(string.toLowerCase());
    }
}

my-context.xml 的内容只是一个.

我定义了一个 aop.xml，正如我所说，它适用于一个类，但不适用于另一个类:

I have an aop.xml defined which as I said works for one class, but not another:

<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <include within="com.example.*" />
        <include within="java.lang.String" />
    </weaver>

    <aspects>
        <aspect name="com.example.PerformMonitor" />
    </aspects>
</aspectj>

我是否遗漏了什么，或者这是 Spring 和 AspectJ 的限制?

Am I missing something, or is this a limitation of Spring and AspectJ?
