differ greatly from reading the normal configuration file. Get some log4j property values for the user configuration, and call the method that you want to set for the Log4j property.Think of Log4j.properties as a struts.xml or a hibernate-cfg.xml. But the difference is that unlike struts and hibernate,

operations that log records are processed.Its syntax is:Log4j.rootlogger = [level], Appendername, Appendername, ...Level is the priority of logging, which is divided into off, FATAL, ERROR, WARN, INFO, DEBUG, all, or your own defined levels. LOG4J recommends using only four levels. Priority levels from high to low are error, WARN, INFO, DEBUG, respectively. By the level defined here. A switch that you can control to the corresponding level of log inf

Og4j Advanced Tips-Location of dynamic configuration log output files The usual use of log4j is to write the output file directly to death in its configuration file (XML or properties), which in many cases is very simple and effective. The disadvantage of this is that if you want this Web application to run, you have to modify the

dimension of the Num class name output (such as: "Org.apache.elathen.ClassName",%c{2} will output elathen. ClassName) %d output log time in the format of%d{yyyy-mm-dd hh:mm:ss,sss}, you can specify a format such as%d{hh:mm:ss} %l output Log event occurrence location, including class name, occurrence thread, number of lines in code %n line break %m output code to specify information, such as info ("message"), output message %p output priority, that is, FATAL, ERROR, etc. %r output the number of

The log4j configuration file is used to set the level, the repository, and the layout of the logger, which can be set in key=value format or in XML format.By configuration, you can create a running environment for log4j.1. The basic format of the configuration file

name and other information, using log4j default initialization process to resolve and configure;4 configuration in the file, through the application server configuration to pass the file name and other information, using a special servlet to complete the configuration. 3. Set the log output level for different appende

(Action) startup level to 3 or 2, preferably by putting the log4j boot before struts. In addition, the log4j is enhanced in the Spring framework:Instead of writing a servlet to start log4j, you can use spring's log4jconfiglistener listener directly. There are several benefits to doing this, and the biggest benefit is

Advantages of 1.LOG4JLog4j is an open source project for Apache, by using log4j, we can control the delivery of log information, we can control the output format of each log, and by defining the level of each log information, we can control the log generation process more carefully. Most interesting of all, these can be configured flexibly with a single configuration file without the need to modify the appl
