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：

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);
    
     @Before
    public void setUp() {
	……
	}
	
	 @Test
    public void sampleTest()
	……
	logger.info("用例执行成功");
	}

	 @After
    public void tearDown() {
        driver.quit();
    }
    
}
