允许$​​ {var}替换的Java库

Question

有谁知道一个Java库,它为文本文件中的$ {var}样式替换提供支持？

Answer 1

Velocity(http://velocity.apache.org),FreeMarker(https://freemarker.apache.org/)

Answer 2

使用 org.apache.commons.lang3.text.StrSubstitutor

示例1（最简单的示例是使用此类替换Java System属性）：

  StrSubstitutor.replaceSystemProperties(
    "You are running with java.version = ${java.version} and os.name = ${os.name}.");

范例2：

   Map valuesMap = HashMap();
   valuesMap.put("animal", "quick brown fox");
   valuesMap.put("target", "lazy dog");
   String templateString = "The ${animal} jumped over the ${target}.";
   StrSubstitutor sub = new StrSubstitutor(valuesMap);
   String resolvedString = sub.replace(templateString);

产生：

   The quick brown fox jumped over the lazy dog.
