1. StackTraceElement
StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
for (StackTraceElement element : stackTrace) {
String className = element.getClassName();
String methodName = element.getMethodName();
String fileName = element.getFileName();
int lineNumber = element.getLineNumber();
// ...
}
2. AspectJ
@Aspect
public class MyAspect {
@Before("execution(* com.example.MyClass.myMethod(..))")
public void beforeAdvice(JoinPoint joinPoint) {
Signature signature = joinPoint.getSignature();
String className = signature.getDeclaringTypeName();
String methodName = signature.getName();
int lineNumber = joinPoint.getSourceLocation().getLine();
// ...
}
}
3. JDI (Java Debug Interface)
VirtualMachineManager virtualMachineManager = Bootstrap.virtualMachineManager();
List<AttachingConnector> connectors = virtualMachineManager.attachingConnectors();
AttachingConnector connector = connectors.get(0);
VirtualMachine virtualMachine = connector.attach(connector.defaultArguments());
List<ReferenceType> classes = virtualMachine.allClasses();
for (ReferenceType referenceType : classes) {
List<Location> locations = referenceType.allLineLocations();
for (Location location : locations) {
String className = location.sourcePath();
String methodName = location.method().name();
int lineNumber = location.lineNumber();
// ...
}
}
