获取类名:
1、在类的实例中可使用this.getClass().getName();但在static
method中不能使用该方法;
2、在static
method中使用方法:Thread.currentThread().getStackTrace()[1].getClassName();
获取方法名:Thread.currentThread().getStackTrace()[1].getMethodName();
获取代码行号:Thread.currentThread().getStackTrace()[1].getLineNumber();
Log 代码:
System.out.println("Class: "+this.getClass().getName()+" method: "+
Thread.currentThread().getStackTrace()[1].getMethodName() +" line:"+
Thread.currentThread().getStackTrace()[1].getLineNumber());

Also, the class returned by the above method may actually be a subclass of the class in which the method is defined. This is because subclasses inherit the methods of their parents; and getClass() returns the actual runtime type of the object. To get the actual

A similar trick can be used to find out the name of the method currently executed:
It's exactly the same principle, just you dig out the name of the method instead of the class.

Description
Below I present you two different ways to get the current Class:Using Thread
Using getClass()
The simplest way to get the name of the class where your code is being executed in is using the
getClass()method present in every java object. Like here:
String clazz = this.getClass().getName();
This works only if executed in an Object, namely an instanciated class. If you try to execute the code above in a
staticmethod. It won't work. Even the keyword
thisis
meaningless in a static method.
Also, the class returned by the above method may actually be a subclass of the class in which the method is defined. This is because subclasses inherit the methods of their parents; and getClass() returns the actual runtime type of the object. To get the actual
class in which a method is defined, use the method below also.
In a
staticmethod you can instead use the following:
String clazz = Thread.currentThread().getStackTrace()[1].getClassName();
Which uses the static method
getStackTrace()to get the whole stacktrace. This method returns an array, where the first element (index 0) is the getStackTrace() you called and the second element (index
1) is the method your code is in.
A similar trick can be used to find out the name of the method currently executed:
String method = Thread.currentThread().getStackTrace()[1].getMethodName();
It's exactly the same principle, just you dig out the name of the method instead of the class.
The code
package org.wikijava.reflection;
public class MethodName { public static void main(String[] args) {
MethodName methodName = new MethodName();
String clazz = Thread.currentThread() .getStackTrace()[1].getClassName();
String method = Thread.currentThread() .getStackTrace()[1].getMethodName();
System.out.println("class name: " + clazz + " Method Name " + method);
methodName.anotherMethod(); }
private void anotherMethod() {
String clazz = this.getClass().getName();
String method = Thread.currentThread() .getStackTrace()[1].getMethodName();
System.out.println("class name: " + clazz + " Method Name " + method); } }
