Velocity 如何输出 Markdown 标题

试过了 Velocity 各种转义也没能找到输出 Markdown 标题的方法，于是干脆将标题设置为自定义为字符串了，具体实现如下：

Java 代码

package com.corning.test;

import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class VelocityAnnotationOutput {

    public static void main(String[] args) throws IOException {

        VelocityEngine ve = new VelocityEngine();
        ve.init();

        try (FileWriter readmeWriter = new FileWriter(new File("demo.txt"))) {
            VelocityContext context = getVelocityContextMD();
            context.put("msg", "Hello World!");
            ve.getTemplate("src/main/resources/templates/demo.vm").merge(context, readmeWriter);
            readmeWriter.flush();
        }

    }

    private static VelocityContext getVelocityContextMD() {
        VelocityContext context = new VelocityContext();
        context.put("H1", "#");
        context.put("H2", "##");
        context.put("H3", "###");
        context.put("H4", "####");
        context.put("H5", "#####");
        return context;
    }

}

Velocity 模版

$H1 $msg
$H2 $msg
$H3 $msg
$H4 $msg
$H5 $msg

模版输出结果

# Hello World!
## Hello World!
### Hello World!
#### Hello World!
##### Hello World!

求问

还有没有更优雅的方式？
