@Override
public String getContentType() {
return "text/html;CHARSET=utf8"; //设定字符集
}
}
/** 因为在把错误信息发功到邮件的时候，中文会出现乱码，所以从
* PatternLayout 继承，并且重写getCotentType方法,并且把字符集设置为utf-8
* 因为在PatternLayout 中 是直接return "text/html;";
**/
//在项目中使用就比较简单了：
//Logger logger = Logger.getLogger(this.getClass());
//logger.fatal("连接服务器发生错误: ", e);
//logger.fatal("连接服务器发生错误: ", e);
//发现了一个原本就有的方法来解决中文乱码问题 //即使在properties中加入： //log4j.appender.MAIL.Encoding=UTF-8
