TTCCLayout in Log4j
In this part of Log4j tutorial we are going to discuss
about the TTCCLayout which is extending DateLayout. It is another
layout format for representing log events output.
It consists of following in its output log event:
- time
- thread
- category (Level)
- nested diagnostic context information
- name (output message)
For example in our output as "16 [main] INFO TTCCLayoutExample.class - First Log".
Note : One of the most important thing while
using TTCCLayout is that "You should not use same TTCCLayout
instance from the different appenders because it is not fully thread safe.
Here is the example code of TTCCLayoutExample
file :
TTCCLayoutExample.java
import org.apache.log4j.*;
public class TTCCLayoutExample {
static Logger logger = Logger.getLogger("TTCCLayoutExample.class");
public static void main(String[] args) {
try
{
FileAppender fileappender =
new FileAppender(new TTCCLayout(),"TTCCoutput.txt");
logger.addAppender(fileappender);
logger.info("First Log");
logger.info("Second Log");
logger.info("Third Log");
logger.info("Fourth Log");
logger.info("See your TTCCoutput.txt");
logger.info("Exiting from the Main method ");
}catch(Exception e){
e.printStackTrace();
}
}
}
|
Output:
After compiling and executing TTCCLayoutExample.java
you will have following output in your TTCCoutput.txt file.
16 [main] INFO TTCCLayoutExample.class - First Log
16 [main] INFO TTCCLayoutExample.class - Second Log
16 [main] INFO TTCCLayoutExample.class - Third Log
16 [main] INFO TTCCLayoutExample.class - Fourth Log
16 [main] INFO TTCCLayoutExample.class - See your TTCCoutput.txt
16 [main] INFO TTCCLayoutExample.class - Exiting from the Main method |
