Simple way to log parameter values in throws exception from methods in Java

At the moment my exceptions are logging text and stack-trace:

throw new RequestValidationException("test exception", parameters, e);

I want to Collect all parameters for the throws exception in all methods. 

HashMap<String, String> parameters = new HashMap<String, String>();   
        parameters.put("testparam", message.toString());

throw new RequestValidationException("test exception", parameters, e);

Now i'm using a hashmap. I have to look at every method and check if it's using a parameter. This will cost me days. There are like thousands of exceptions in the code, is there a simple way to show the values?

You can use slf4j-ext for logging method parameters. They are logged at the trace level.

private static final XLogger xlogger = XLoggerFactory.getXLogger(MyClass.class);

Then you can use at start and end of your methods like this:

protected void Method1(Message aMessage){
    xLogger.entry(aMessage);
    ...
    xLogger.exit();
}
