Reprint: http://www.blogjava.net/sxyx2008/

Requirements Description: Any program will have bugs, although the project after repeated testing, has been running the line, but will inevitably encounter a variety of errors, here easily configure log4j to implement error message email notification.
Two files: Web.xml log4j.properties
Xml

Add the following code to the Web.xml

<!--setting Context parameters-->
    <context-param>
        <!--log4j configuration file location-->
        <param-name> Log4jconfiglocation</param-name>
        <param-value>/web-inf/classes/log4j.properties</ param-value>
    </context-param>
    <context-param>
        <param-name> log4jrefreshinterval</param-name>
        <param-value>6000</param-value>
    </context-param >
    <!--log4j listener-->
    <listener>
        <listener-class> Org.springframework.web.util.log4jconfiglistener</listener-class>
    </listener>

Note: You have configured your own custom layout in the above log4j.properties file, because log4j is the default plain text method. This is not convenient for us to view in the mail, so cover it's layout, custom belongs to our own layout
Custom class Com.quartz.demo.Loger4JHTMLLayOut Complete this feature

Package Com.quartz.demo;

Import Org.apache.log4j.HTMLLayout;

public class Loger4jhtmllayout extends htmllayout{
    
    @Override public
    String getContentType () {return
        text /html;charset=utf-8 "; 
    }
}

That is, simply set contenttype as text/html
