是否可以通過在Apache Velocity中定義模板來生成Java代碼？

Question

我需要使用Velocity Template概念生成Java文件。 請您指導一下。

Java代碼應包含一些方法，導入和變量...

謝謝，伊斯瓦爾

對於Velocity / Java部分，您或多或少需要這樣做：

// factory and an engine instance
VelocityEngineFactory velocityEngineFactory = new VelocityEngineFactory();
VelocityEngine engine = velocityEngineFactory.createVelocityEngine();
// now you need to give the variables you wanna have access from velocity script
VelocityContext context = new VelocityContext(properties);

ByteArrayOutputStream temp = new ByteArrayOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(temp));
// generate the result, where scriptString is the velocity script
engine.evaluate(context, bufferedWriter, null, scriptString);
bufferedWriter.flush();
textResultant = temp.toString();

因此，您可以創建一個腳本，對其進行加載並以編程方式對其進行處理。
