Java Velocity模板引擎-简单字符串生成

利用Velocity模板引擎，可以将一段字符串作为模板，通过模板内置变量来生成代码。

package src;import java.io.StringWriter;
import java.util.Date;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;
import org.apache.velocity.app.VelocityEngine;public class Main {public static void main(final String[] args) {try {VelocityEngine velocityEngine = new VelocityEngine();velocityEngine.init();Velocity.init();/* lets make a Context and put data into it */    VelocityContext context = new VelocityContext();    context.put("name", "Velocity");context.put("project", "Jakarta");context.put("now", new Date()); /* lets make our own string to render */    String str = "We are using $project $name to render this. 中文测试  $!dateFormatUtils.format($!now,'yyyy-MM-dd')";StringWriter stringWriter = new StringWriter();Velocity.evaluate(context, stringWriter, "mystring", str);System.out.println(" string : " + stringWriter); } catch (final Exception e) {System.out.print("系统异常：" + e.getMessage());e.printStackTrace();}}}
