Java : 获取当前执行的函数名

方式1: 使用函数内部类/匿名类对象的 getEnclosingMethod 方法

public class MethodNameTest {

    public static void testMethod() {
        String methodName = new Object() {}
                .getClass()
                .getEnclosingMethod()
                .getName();
        System.out.println(methodName);
    }

    public static void main(String[] args) {
        testMethod();
    }

}

运行结果:

testMethod

方式2: 从异常堆栈跟踪中获取方法名

public class MethodNameTest {

    public static void testMethod() {
        StackTraceElement[] stackTrace = new Throwable().getStackTrace();
        String methodName = stackTrace[0].getMethodName();
        System.out.println(methodName);
    }

    public static void main(String[] args) {
        testMethod();
    }

}

运行结果:

testMethod

方式3: 从线程堆栈跟踪中获取方法名

public class MethodNameTest {

    public static void testMethod() {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        String methodName = stackTrace[1].getMethodName();
        System.out.println(methodName);
    }

    public static void main(String[] args) {
        testMethod();
    }

}

运行结果:

testMethod
