Three ways to load VM files in the transfer velocity

Velocity中加载vm文件的三种方式 velocitypropertiespath Velocity中加载vm文件的三种方式：   方式一：加载classpath目录下的vm文件 Properties p = new Properties(); p.put( "file.resource.loader.class" , "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader" ); Velocity.init(p); ... Velocity.getTemplate(templateFile);     方式二：根据绝对路径加载，vm文件置于硬盘某分区中，如：d: //tree.vm Properties p = new Properties(); p.setProperty(VelocityEngine.FILE_RESOURCE_LOADER_PATH, "d://" ); Velocity.init(p); ... Velocity.getTemplate( "tree.vm" );     方式三：使用文本文件，如：velocity.properties，配置如下： #encoding input.encoding=UTF- 8 output.encoding=UTF- 8 contentType=text/html;charset=UTF- 8 不要指定loader.   再利用如下方式进行加载 Properties p = new Properties(); p.load( this .getClass().getResourceAsStream( "/velocity.properties" )); Velocity.init(p); ... Velocity.getTemplate(templateFile); package com.study.volicity; import java.io.IOException; import java.io.StringWriter; import java.util.Properties; import org.apache.velocity.app.Velocity; import org.apache.velocity.Template; import org.apache.velocity.VelocityContext; public class Test {           public static void main(String args[]) throws IOException {          Properties pros = new Properties();          pros.load(Test. class .getClassLoader().getResourceAsStream( "velocity.properties" ));          Velocity.init(pros);          VelocityContext context = new VelocityContext();          context.put( "name" , "Velocity" );          context.put( "project" , "Jakarta" );          /* lets render a template 相对项目路径 */          Template template = Velocity.getTemplate( "/view/header.vm" );          StringWriter writer = new StringWriter();          /* lets make our own string to render */          template.merge(context, writer);          System.out.println(writer);      } }
