Play Spring MVC (v)----Integrate log4j in spring

Based on the front, this article summarizes how to configure log4j in spring, and gives a link to the complete project at the end of this article.

The first is the code to be added in Web. xml:

<!--6. Configure LOG4J-<!--6.1 Configuration load Log4j.xml file path--<context-param>   <param-name>log4jconfiglocation </param-name>   <param-value>/WEB-INF/classes/spring/log4jConfig.xml</param-value> </ Context-param> <!--6.2 Configuring Log4j.xml variables--<context-param>   <param-name>rootlevel</ param-name>   <param-value>DEBUG</param-value> </context-param> <context-param>   <param-name>loggingLevel</param-name>   

Then add Log4jconfig.xml under the Src/config/spring folder

<?xml version= "1.0" encoding= "UTF-8"? ><!

The 2.root tag is the default output form of log, and if the log of a class does not explicitly specify its output lever and format in loggers, it will take the format defined in root-<root> <level value= "${ro Otlevel} "></level> <appender-ref ref=" Default-appender "/> <appender-ref ref=" Error-appender "/> </root></log4j:configuration>

Next, copy the LOG4J.DTD under the Log4jjar package Log4j-1.2.17\org\apache\log4j\xml to src/config/spring.

Of course, people need to import the appropriate package.
