1、需要的jar如下:
!-- log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.4</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.4</version> <scope>runtime</scope> </dependency>
2、将log4j.properties放入项目src路径下即可,虚拟机会自动加载日志配置文件,文件内容如下:
### set log levels ### log4j.rootLogger = DEBUG , C , D , E ### console ### log4j.appender.C = org.apache.log4j.ConsoleAppender log4j.appender.C.Target = System.out log4j.appender.C.layout = org.apache.log4j.PatternLayout log4j.appender.C.layout.ConversionPattern = [mybatis_study][%p] [%-d{yyyy-MM-dd HH\:mm\:ss}] %C.%M(%L) | %m%n ### log file ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ../logs/mybatis_study.log log4j.appender.D.Append = true log4j.appender.D.Threshold = INFO log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = [mybatis_study][%p] [%-d{yyyy-MM-dd HH\:mm\:ss}] %C.%M(%L) | %m%n ### exception ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File = ../logs/mybatis_study_error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = [mybatis_study][%p] [%-d{yyyy-MM-dd HH\:mm\:ss}] %C.%M(%L) | %m%n ###mybatis show sql### log4j.logger.com.ibatis=debug log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=debug log4j.logger.com.ibatis.common.jdbc.ScriptRunner=debug log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=debug log4j.logger.java.sql.Connection=debug log4j.logger.java.sql.Statement=debug log4j.logger.java.sql.PreparedStatement=debug
3、也可以配置log4j.xml,如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- [控制台STDOUT] --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="encoding" value="GBK" /> <param name="target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p %c{2} - %m%n" /> </layout> </appender> <!-- [公共Appender] --> <appender name="DEFAULT-APPENDER" class="org.apache.log4j.DailyRollingFileAppender"> <param name="File" value="${webapp.root}/logs/rms-default.log" /> <param name="Append" value="true" /> <param name="encoding" value="GBK" /> <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p %c{2} - %m%n" /> </layout> </appender> <!-- [错误日志APPENDER] --> <appender name="ERROR-APPENDER" class="org.apache.log4j.DailyRollingFileAppender"> <param name="File" value="${webapp.root}/logs/rms-error.log" /> <param name="Append" value="true" /> <param name="encoding" value="GBK" /> <param name="threshold" value="error" /> <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p %c{2} - %m%n" /> </layout> </appender> <!-- Root Logger --> <root> <level value="${rootLevel}"></level> <appender-ref ref="DEFAULT-APPENDER" /> <appender-ref ref="ERROR-APPENDER" /> <appender-ref ref="console" /> </root> </log4j:configuration>
