强大的log4j，错误信息自动发送至邮箱

      前几天看师兄都不用看服务器，天天盯着邮箱看就能知道代码哪里出问题了。手痒，我就试试，写了一个小的程序Java的

导入jar文件

                                                 log4j-1.2.1.jar

                                                 activation.jar

                                                 mail.jar

项目结构：

                                                                                          

log4j.properties

log4j.appender.infoR.Append = true
log4j.appender.infoR.Threshold = INFO
#log4j.appender.infoR.DatePattern='_'yyyy-MM-dd-HH'.log'

log4j.appender.infoR.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss} [ %l ] %m%n  

#errorR

log4j.appender.errorR.File =f:/errorLog.txt

public class Logger4jHTMLLayout extends HTMLLayout {

	@Override
    public String getContentType() {
        return "text/html;charset=utf-8"; 
    }
}

checkLog4j1.java   测试类

import org.apache.log4j.Logger;

/**

 */
public class checkLog4j1 {
	private static Logger info = Logger.getLogger("InfoLogger");  
    private static Logger error = Logger.getLogger("ErrorLogger");  
	public static void main(String[] args) {

		error.error("sdadfwf");
	}
}

运行，邮箱收到如下邮件

注意，大家一定要重写getContentType方法，防止乱码
