("Start"); logger.info("Running"); logger.info("End"); } }
At this time, you will find that "Start" "Running" "End" is printed twice on the console, because the log is output once and ConsoleHandler outputs it once.
The Handler object obtains the log information from the Logger and exports the information. For example, it can write the information to the console or file, send the information to the Network Log service, or forward it to the operating system log.You can
C # Use log4net to easily record local logs in step 4,
Here, record the steps for logging local logs using log4net in my project. It is difficult and mysterious before it is done. Once it is done, it is actually not that difficult. In fact, everything is the same. Next I will share my experience with log4Net.
Step 1: search for and download the Log4Net dll file from Nuget package management in Visual Studio, for example:
Select the project to be installed (select the class library that require
); testLogger1.setLevel (Level. SEVERE); // set it to a high-level infoLogger.info ("this is the record of infoLogger"); infoLogger. setLevel (Level. INFO); // set it to infoLogger.info ("this is the record of infoLogger ");}}
Output result:
4. Handler class of Logger
The Handler object obtains the log information from the Logger and exports the information. For example, it can write the information to the console or file, send the information to the Network Log service, or forward it to the op

The list of generated log files can be found below:

The log file currently being written is info. log.
The key code is as follows:
/*** Create a log file ** @ param lfi */private void createLogFile (LogFileItem lfi) {// The current system date String currPCDate = TimeUtil. getPCDate ('-'); // if the size of a single file is exceeded, split the file if (lfi. fullLogFileName! = Null lfi. ful

A thread can contain multiple Handler objects. In the logoff. loop () function, different messages correspond to different Handler objects, and different handleMessage () functions are called back.
