You can try StrSubstitutorfrom Apache common text
您可以从 Apache common text 中尝试StrSubstitutor
Map valuesMap = HashMap();
valuesMap.put("animal", "quick brown fox");
valuesMap.put("target", "lazy dog");
String templateString = "The ${animal} jumps over the ${target}. ${undefined.number:-1234567890}.";
StrSubstitutor sub = new StrSubstitutor(valuesMap);
String resolvedString = sub.replace(templateString);
