VelocityUtil { public static String getMergeOutput(VelocityContext context, String templateName) { Template template = velocityEngine.getTemplate(templateName); StringWriter sw = new StringWriter(); template.merge(context, sw); String output = sw.toString(); try { sw.close(); } catch (IOException e) { e.printStackTrace(); } return output; }  static String getMergeOutput(VelocityContext context, String templateName);  }### Answer:
@Test public void test() { VelocityContext context = new VelocityContext(); context.put("name", "Victor Zhang"); context.put("project", "Velocity"); System.out.println(VelocityUtil.getMergeOutput(context, "template/hello.vm")); }
