Velocity generates static page code

First, two necessary jar packages are required:

Velocity. Jar velocity-tool-view.jar

Web. xml

  <!-- load velocity property -->  <servlet>       <servlet-name>velocity</servlet-name>       <servlet-class>org.apache.velocity.tools.view.servlet.VelocityLayoutServlet</servlet-class>       <init-param>           <param-name>org.apache.velocity.properties</param-name>           <param-value>/WEB-INF/velocity.properties</param-value>       </init-param>      </servlet>  <servlet-mapping>      <servlet-name>velocity</servlet-name>      <url-pattern>*.vm</url-pattern>  </servlet-mapping>

velocity.properties

input.encoding=utf-8output.encoding=utf-8WebRoot.resource.loader.class = org.apache.velocity.tools.view.servlet.WebappLoaderwebapp.resource.loader.path=/WEB-INF/vm/

 

Background call:

String realpath = request. getrealpath ("/"); // template path string urlvm = "/WEB-INF/Vm/test. VM "; // The generated HTML path. In the webroot HTML folder, string urlhtml = realpath +"/html/test.htm "; // set the template element velocitycontext context = new velocitycontext (); context. put ("title", "Hello word"); createhtml. createhtml (realpath, urlvm, urlhtml, context );

CreateHtml.java 

Package COM. velocity; import Java. io. printwriter; import Java. util. properties; import Org. apache. velocity. template; import Org. apache. velocity. velocitycontext; import Org. apache. velocity. app. velocity; public class createhtml {public static void createhtml (string realpath, string urlvm, string urlhtml, velocitycontext context) {// load path properties prop = new properties (); prop. setproperty (velocity. file_resource_loader_path, realpath); try {velocity. init (PROP); // initialize VM template = new template (); template = velocity. gettemplate (urlvm, "UTF-8"); // generate the HTML page printwriter writer = new printwriter (urlhtml); template. merge (context, writer); // remember to disable stream writer. close ();} catch (exception e) {// todo auto-generated Catch Block E. printstacktrace ();}}}

 

In this way, a static page is generated under the server, and the page is directly accessed, for example, http: // localhost: 8080/html/test.htm
