工做笔记:在myeclipse 中建立一个java projectjava
建立一个 TestSlf4J 类apache
|
import org.slf4j.Logger;api
import org.slf4j.LoggerFactory;app public class TestSlf4J {
private static final Logger logger =LoggerFactory.getLogger(TestSlf4J.class);
public static void main(String[] args) {
logger.error("Hello world {}");
try {
int i = 1/0;
} catch (Exception e) {
logger.error("出现异常",e);
}
}
} eclipse |
同时把slf4j-api-1.1.jar slf4j-log4j12-1.6.1.jar log4j-1.2.16.jar 放入项目里。blog
再添加一个log4j.propertiesip
| # FRAMEWORK
log4j.rootLogger=ERROR,FRAMEWORK
#framework
# Daily make a log file
log4j.appender.FRAMEWORK=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FRAMEWORK.File=e:/test.log
log4j.appender.FRAMEWORK.DatePattern='_'yyyy-MM-dd'.log'
log4j.appender.FRAMEWORK.layout=org.apache.log4j.PatternLayout
log4j.appender.FRAMEWORK.layout.ConversionPattern=%d [%t] %-5p %c - %m%nget |
项目结构如图：io
最后 运行TestSlf4J类在e盘就生成了一个test.log文件 生成内容以下：table
