java - 速度模板作为 Java 中的字符串

Question

我有一个 java 字符串，它基本上是一个速度模板。

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 中评估上述字符串并获得结果？

Answer 1

您必须使用 Velocity.Evaluate 检查此 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);
  }
}
