logger 报错

logger 报错：（log4j 起不来，log message打不出来）

No appenders could be found for logger (com.vip.qa.android.base.DriverFactory).
log4j:WARN Please initialize the log4j system properly.

原因： log4j.properties 文件没不存在，或存在，但放错路径

解：把log4j.properties放入mvn 默认的resources跑路径下面：./src/main/resources/

ok了：

依赖：

        <dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.2</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency>

log4j.properties 文件：

### set base log level ###
log4j.rootLogger = debug### set tesecase log level ###
log4j.logger.com.vip.qa.android=debug, stdout### set remote server log level ###
log4j.logger.org.apache.http=off### set proxy log level ###
log4j.logger.org.eclipse.jetty=info, stdout
log4j.logger.com.vip.test.proxy=info, file### output log to console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%t-%c]-[%p]  %m%n### Define the file appender ###
log4j.appender.file=org.apache.log4j.FileAppender 
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%t-%c]-[%p]  %m%n
log4j.appender.file.File=logs/${date}_${testCaseName}.log
log4j.appender.file.ImmediateFlush=true  
log4j.appender.file.Threshold=info 
log4j.appender.file.Append=true  
log4j.appender.file.encoding=UTF-8

要定义呀：

import org.apache.log4j.Logger;public class TestVOS {private static Logger logger = Logger.getLogger(DriverFactory.class);@Beforepublic void setUp() {……}@Testpublic void sampleTest()……logger.info("用例执行成功");}@Afterpublic void tearDown() {driver.quit();}}
