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);
}
}
