Spring MVC中使用logback日志

     需要导入的jar包有：logback-core-0.9.29.jar，logback-classic-0.9.29.jar，slf4j-api-1.6.1.jar

     下面来看看logback.xml里面的内容配置：

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

<configuration>
<!-- 日志保存路径为tomcat下面的logs下面的mobileLog文件夹，logback会自动创建文件夹，这样设置了就可以输出日志文件了 -->
<substitutionProperty name="logbase" value="${catalina.base}/logs/mobileLog/" />

<!-- 这个是要配置输出文件的-->
<jmxConfigurator />

<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date [%thread] %-5level %logger{80} - %msg%n</pattern>

</layout>
</appender>

<!-- 文件输出日志 (文件大小策略进行文件输出，超过指定大小对文件备份) -->
<appender name="logfile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<Encoding>UTF-8</Encoding>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<File>${logbase}%d{yyyy-MM-dd}.log.html</File>
<FileNamePattern>${logbase}.%d{yyyy-MM-dd}.log.html.zip</FileNamePattern>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>2MB</MaxFileSize>
</triggeringPolicy>
<layout class="ch.qos.logback.classic.html.HTMLLayout">
<pattern>%date%level%thread%10logger%file%line%msg</pattern>
</layout>
</appender>
<!-- Output by Email -->
<appender name="Email" class="ch.qos.logback.classic.net.SMTPAppender">
<SMTPHost>stmp host name</SMTPHost> <To>Email Address</To> <To>Email Address</To>
<From>Email Address</From>
<Subject>TESTING Email Function: %logger{20} - %m</Subject>
<layout class="ch.qos.logback.classic.html.HTMLLayout">
<pattern>%date%level%thread%10logger%file%line%msg</pattern>
</layout>
</appender>

<!-- Output to Database -->
<appender name="DB" class="ch.qos.logback.classic.db.DBAppender">
<connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
<driverClass>com.MySQL.jdbc.Driver</driverClass>
<url>jdbc:mysql://localhost:3306/test</url>
<user>root</user>
<password>trend_dev</password>
</connectionSource>
</appender>
<root>
<level value="ERROR" />
<appender-ref ref="stdout" />
<appender-ref ref="logfile" />
</root>

< /configuration>

使用的时候可以这样定义变量：Logger logger = LoggerFactory.getLogger(AdministratorController.class);

需要import两个内容：

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

后面的使用就简单了：

logger.debug(" 日志记录");

logger.info(" 日志记录");

logger.error(" 日志记录");

设置好后，可以输出到文件中，也可以输出到输出框中。
