log4j问题
配置文件

Java code

log4j.rootCategory=INFO, stdout , Rlog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.R=org.apache.log4j.RollingFileAppender   log4j.appender.R.File=d\:/batchprocessdata/log.log #log4j.appender.R.DatePattern = '.'yyyy-MM-dd  log4j.appender.R.Append=true    log4j.appender.R.MaxFileSize=4MB    log4j.appender.R.MaxBackupIndex=1000    log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd } [%c]-[%p] %m%n log4j.logger.org.springframework=DEBUGlog4j.logger.org.hibernate=DEBUGlog4j.logger.org.hibernate.ps.PreparedStatementCache=DEBUGlog4j.logger.com.myproject=DEBUG

Java code

import java.util.logging.Logger;import java.util.regex.Pattern;public class tt {    private static final Logger LOG = Logger.getLogger(tt .class.getName());    public static void main(String[] args) {        PropertyConfigurator.configure("log4j.properties");        LOG.info("sdfsdfasdf");        LOG.info("sdfsdfasdf");         }    }

能在指定文件夹下面建立log文件，但是就是内容就是没有被记录在log中。

[解决办法]
import org.apache.log4j.Logger;
import java.util.regex.Pattern;

public class tt {
private static final Logger LOG = Logger.getLogger(tt .class.getName());
public static void main(String[] args) {

// PropertyConfigurator.configure("log4j.properties");
LOG.info("sdfsdfasdf");
LOG.info("sdfsdfasdf");
}
}
