简单回答ReflectionUtils.getCallingClass(0)

长答案(代码，Groovy)

package my

import org.codehaus.groovy.reflection.ReflectionUtils
import java.lang.reflect.Field
import java.lang.reflect.Method

trait Reflector {

    static String[] fieldNames() {
        List<String> names = []
        Arrays.asList(naturalFields()).forEach { Field fl -> names.add(fl.name) }
        return names.toArray() as String[]
    }

    static Field[] naturalFields() {
        return finalClass().getDeclaredFields().findAll { Field fl -> !fl.synthetic }.collect()
    }

    static Method[] naturalMethods() {
        return finalClass().getDeclaredMethods().findAll { Method md -> !md.synthetic }.collect()
    }

    static Class finalClass() {
        return ReflectionUtils.getCallingClass(0)
    }

}

class Demo implements Reflector {

    int archived = 0
    int demo = 100

    static void playToo() {
        println finalClass()
    }

}

println Demo.finalClass() // class my.Demo
println Demo.naturalFields() // [private int my.Demo.archived, private int my.Demo.demo]
println Demo.fieldNames() // [archived, demo]

这个方法做同样的事情，但更简单一点，可能性能更好一点，在你使用反射的情况下，它会自动跳过那些帧。唯一的问题是它可能不会出现在非sun的jvm中，尽管它包含在JRockit 1.4—>1.6的运行时类中。(重点是，它不是一个公共类)。

sun.reflect.Reflection

    /** Returns the class of the method <code>realFramesToSkip</code>
        frames up the stack (zero-based), ignoring frames associated
        with java.lang.reflect.Method.invoke() and its implementation.
        The first frame is that associated with this method, so
        <code>getCallerClass(0)</code> returns the Class object for
        sun.reflect.Reflection. Frames associated with
        java.lang.reflect.Method.invoke() and its implementation are
        completely ignored and do not count toward the number of "real"
        frames skipped. */
    public static native Class getCallerClass(int realFramesToSkip);

至于realFramesToSkip的值应该是什么，Sun 1.5和1.6虚拟机版本的java.lang. lang. js。系统中，有一个名为getCallerClass()的包保护方法，它调用sun.reflect. reflect. getCallerClass(3)，但在我的助手实用程序类中，我使用了4，因为有添加的助手类调用的帧。

Java 9 - JEP 259:栈遍历API

JEP 259为堆栈遍历提供了一个有效的标准API，允许对堆栈跟踪中的信息进行轻松过滤和延迟访问。在栈遍历API之前，访问栈帧的常见方法有:

的数组返回 包含类名和方法的StackTraceElement对象 每个堆栈跟踪元素的名称。 SecurityManager::getClassContext是一个受保护的方法 SecurityManager的子类来访问类上下文。 JDK-internal sun.reflect。Reflection::getCallerClass方法，你不应该使用它

使用这些api通常效率很低:

这些api要求VM急切地捕获整个快照 堆栈，它们返回表示整个堆栈的信息。 没有办法避免检查所有帧的代价，如果 调用者只对堆栈上的前几帧感兴趣。

为了找到直接调用者的类，首先获取一个StackWalker:

StackWalker walker = StackWalker
                           .getInstance(StackWalker.Option.RETAIN_CLASS_REFERENCE);

然后调用getCallerClass():

Class<?> callerClass = walker.getCallerClass();

或者遍历StackFrame并获得前面的第一个StackFrame:

walker.walk(frames -> frames
      .map(StackWalker.StackFrame::getDeclaringClass)
      .skip(1)
      .findFirst());

我以前做过。您可以只创建一个新的异常，并在不抛出异常的情况下获取其堆栈跟踪，然后检查堆栈跟踪。正如另一个答案所说，这是非常昂贵的——不要在一个紧密的循环中进行。

我以前在一个性能不太重要的应用程序上为一个日志实用程序做过这样的操作(实际上，性能几乎不太重要——只要你将结果显示给一个动作，比如快速单击按钮)。

这是在你可以得到堆栈跟踪之前，异常只是有. printstacktrace()，所以我必须重定向系统。输出到我自己创建的流，然后(new Exception()).printStackTrace();重定向系统。返回并解析流。有趣的东西。
