Messages in a Loop

Hi,

I´m using log4j version 1-3 alpha 6, working with Socket and File Appenders. 

I would like to know if i can prevent repeated messages generated in a
loop appearing in files or remote receivers only by configuring Log4j,
i.e. not writing additional code. Is it possible?

Thanks,
Ivan

Hi Ivan, 

I think you could do like this :

class A {

Logger loggerA = Logger.getLogger(A.class.getName());
boolean doLogging = true;

void loop {
   while (true) {
   // some logix  
   ...
   // some verification
   if (condition &amp;&amp; doLogging) {
      loggerA.error("xxx"); // error msg 
      doLogging = false;
   }  
   // sleep for a while...
  }


Hope it can help,

Antoine

James,

It should work with any loop, like this:

class A {

Logger loggerA = Logger.getLogger(A.class.getName());

void loop {
   while (true) {
   // some logix  
   ...
   // some verification
   if (condition) {
      loggerA.error("xxx"); // error msg 
   }  
   // sleep for a while...
  }
}

the problem is I have this kind of behavior in many parts of my code,
and I wanted this "error msg" printed only once while the condition is
true, without creating additional conditional variables inside the
code.

is it possible to do it?

ps: I should try Aron solution as well, but it requires some extra coding too

Any loop or one specific loop?  If it is one specific loop you could
configure the logger that it uses.
