log4j configuration xml

The default log framework provided by hibernate3 is slf4j. The SLF of hibernate3 is only a log interface, while the default log framework provided by hibernate3 is rarely used by companies or projects in actual development, here we record a log framework that uses log4j to replace the implementation of the slf4j log framework. The specific configuration and implementation are as follows: I. added the

SPRINGMVC+HIBERNATE+LOG4J+SLF4J is used in the application. The log level of the log4j is tuned to info. However, when the Web container (Tomcat) starts and runs, the debug-level logs in the spring,hibernate frame are constantly being brushed, causing the log file to soar and the disk to explode in a few days. In response to this problem on the Internet to find a lot of methods, are no effect or palliative

Preface I've been saying, how to read the Log4j profile log4j.properties. The next discussion is: How to set the path of the log file created in log4j. Tomcat's okay. For complex WebLogic, this is how to set the path, because it doesn't understand how to press the war file. In the last article Also mentioned in the log (log4j)

Log4j is a Java-based open-source log component. log4j has powerful functions. We can output log information to the console, files, and user interfaces, it can also output Event recorders and some system resident processes to the operating system. It is worth mentioning that log4j allows you to easily customize log formats and log levels, and helps developers ful

The three main components of the log4j configuration file are:Logger,appender and layout, respectively, log type, log output destination, log output format.Log4j.rootlogger = [Level],appendername, Appendername, ...(Level is the error, Appendername is the output destination, this example is set to MyLog, you can define more than one) level priority is fatal, ERROR, WARN, INFO, DEBUG 5 levels. By defining the

If you use the spring plug-in to create a spring template project, it defaults to log4j, as long as you change the log4j configuration to use, if you create a project, you need to load the log4f package, use the following steps 1.pom.xml join Log4j's dependency pack 2. Create Log4j.xml under Src/main/resources Log4j.xml defines 3 Appender, which is the location

You need 4 jar packages first. As followsHttp://pan.baidu.com/s/1i4k3fiHThe following package is included in the interim and can be placed in the project Lib.In addition to the need for a configuration file, the sharing link is as follows.

The production of a log in the project is necessary for a project, now used in a more extensive, more popular log tools have log4j; This log tool is actually very convenient to use, and when used, it was created like Java.util.logging.Logger, The JDK log logging information is obtained and exported using the handler object, and the exported information is formatted by formatter object and log4j log informat

log4j Introduction log4j has three main components: loggers (Logger), appenders (output source), and layouts (layout). This can be simply understood as the log category, where the logs are to be exported and how the logs are exported. The combined use of these three components makes it easy to record the type and level of information, and to control the style and location of the log output at run time. 1. L

When log4j is called to output logs in XXX class, the following statement is called at first, Public static logger = org. Apache. log4j. Logger. getlogger (class name. Class. getname ()); This method can be used to set the Log Level of the class in the configuration file. For example, add the following lines to the configurat
