速度模板作为 Java 中的字符串 [英] Velocity template as a String in Java

问题描述

我有一个 java 字符串，它基本上是一个速度模板.

I have a java String which is basically a velocity template.

String vt = "#foreach ($number in [1..34])  $number += $number  #end"
String result = *String_vt_calculated_by_Velocity_Engine*;
System.out.println(result);

如何在 Java 中计算上述字符串并得到结果?

How can I evaluate the above String in Java and get the result?

推荐答案

你必须使用 Velocity.Evaluate 检查这个 文档

You have to use Velocity.Evaluate check this Document

import java.io.StringWriter;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;
public class LoadTemplateFromStringTest {

  public static void main(String[] args)  {
       VelocityContext context = new VelocityContext();

       StringWriter sw = new StringWriter();
      String vt = "#foreach ($number in [1..34])  $number += $number  #end";
        Velocity.evaluate( context, sw, "", vt);
        System.out.println(sw);
  }
}
