采用字符串作为模板内容的 Velocity简单实例。
import java.io.StringWriter;
import java.util.Date;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;
public class HelloVelocity {
/**
* @param args
*/
public static void main(String[] args) throws Exception {
// 初始化并取得Velocity引擎
VelocityEngine ve = new VelocityEngine();
ve.init();
// 取得velocity的模版内容, 模板内容来自字符传
String content = "";
content += "Welcome $name to Javayou.com! ";
content += " today is $date.";
// 取得velocity的上下文context
VelocityContext context = new VelocityContext();
// 把数据填入上下文
context.put("name", "javaboy2012");
context.put("date", (new Date()).toString());
// 输出流
StringWriter writer = new StringWriter();
// 转换输出
ve.evaluate(context, writer, "", content); // 关键方法
System.out.println(writer.toString());
}
}
