How to run a Java class when Tomcat is started

Just set up a listener and specify a description in Web. Xml.

Web. XML is actually a description file that will be read when Tomcat starts, such as when accessing the server home page can be specified in the inside, there is a corresponding tag. Here's an explanation: http://blog.chinaunix.net/uid-20399471-id-1687965.html

To implement this listener interface:

1  Public classMyservletcontextlistenerImplementsServletcontextlistener {2 3 @Override4    Public voidcontextdestroyed (servletcontextevent arg0) {5     //Notification that, the servlet context is on to being shut down. 6   }7 8 @Override9    Public voidcontextinitialized (servletcontextevent arg0) {Ten     //Do all the tasks, the need to perform just after the server starts One  A     //Notification The Web application initialization process is starting -   } -  the}

Then write the listener tag in Web. XML and add the Listener class:

Mytestlistener replace the class name that implements the Servletcontextlistener interface yourself

< Listener >     < Listener-class > [Package]. Mytestlistener</listener-class>    </listener  >
