web.xml中配置：

logbackConfigLocation

file:/datum/Data/conf/config/logback.xml

logbackConfigLocation

file:E:\\datum\\data\\conf\\logback.xml

其中file:一定要有。

com.cxfmvcstu.comn.LogbackConfigListener

LogbackConfigListener为自己的实现类

import javax.servlet.ServletContextEvent;

import javax.servlet.ServletContextListener;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.core.io.UrlResource;

import ch.qos.logback.classic.LoggerContext;

import ch.qos.logback.classic.joran.JoranConfigurator;

import ch.qos.logback.core.joran.spi.JoranException;

/**

* @description

* @path com.cxfmvcstu.comn.LogbackConfigListener

* @author lijun.justin

*/

public class LogbackConfigListener implements ServletContextListener {

private static final Logger logger = LoggerFactory.getLogger(LogbackConfigListener.class);

private static final String CONFIG_LOCATION = "logbackConfigLocation";

@Override

public void contextInitialized(ServletContextEvent event) {

// 从web.xml中加载指定文件名的日志配置文件

String logbackConfigLocation = event.getServletContext().getInitParameter(CONFIG_LOCATION);

String fn = event.getServletContext().getRealPath(logbackConfigLocation);

try {

UrlResource urlResource = new UrlResource(logbackConfigLocation);

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();

loggerContext.reset();

JoranConfigurator joranConfigurator = new JoranConfigurator();

joranConfigurator.setContext(loggerContext);

//joranConfigurator.doConfigure(fn);

joranConfigurator.doConfigure(urlResource.getFile().getAbsolutePath());

logger.debug("loaded slf4j configure file from {}", fn);

} catch (JoranException e) {

logger.error("can loading slf4j configure file from " + fn, e);

}catch (Exception e) {

logger.error(e.getMessage(), e);

}

}

@Override

public void contextDestroyed(ServletContextEvent event) {

}

}

要依赖于spring的UrlResource类。里面无用的代码，读者自己精简一下

logback.xml的配置示例：

%date [%thread] %-5level %logger{80} - %msg%n

class="ch.qos.logback.core.rolling.RollingFileAppender">

INFO

ACCEPT

DENY

D:/logs/INFO.%d{yyyy-MM-dd}.log

30

%date [%thread] %-5level %logger{80} - %msg%n

ERROR

ACCEPT

DENY

D:/logs/error.%d{yyyy-MM-dd}.log

30

%date [%thread] %-5level %logger{80} - %msg%n
