Velocity templates Use

The introduced JAR package:

1 Import org.apache.velocity.Template; 2 Import Org.apache.velocity.VelocityContext; 3 Import org.apache.velocity.app.Velocity; 4 Import Org.apache.velocity.app.VelocityEngine; 5 Import Org.apache.velocity.tools.generic.DateTool; 6 import Org.apache.velocity.tools.generic.NumberTool;

Jar package can be downloaded to the official website

http://velocity.apache.org/engine/devel/

Sample code:

1 /**2 * Generate VMS3      * @paramVmpackage The package name where the VM resides4      * @paramVmname5      * @paramListName6      * @paramObjects7      * @return8      * @throwsException9      */Ten      Public StaticString GENERATEVM (String vmpackage, String vmname, String listname, list<?extendsObject> objects)throwsexception{ One         if(Objects.size () >0){ AProperties p =NewProperties (); -String classpath = velocityutils.class.

The above function is called:

1String vmpagckage = "com/cpinfo/his/template/emr/";2String vmname = "PARTOGRAM_DETAIL_INFOS.VM";3String vm = VELOCITYUTILS.GENERATEGRIDVM (vmpagckage, Vmname, "BS", EMS);4             5Response.setcontenttype ("Text/xml;charset=utf-8");6PrintWriter PW =Response.getwriter ();7 Pw.print (VM);8 Pw.flush ();9Pw.close ();
