Java Pattern 활용하기

$${aaa.bbb.ccc} 이라는 템플릿에 대한 검증 또는 데이터 저장하는 코드.

public class TemplatePropertyMaker {
 
 public static boolean isAvailable(String value) {
  return getGroup(value) == null ? false : true;
 }
 
 private static String getGroup(String value) {
  Pattern pattern = Pattern.compile("\\$\\$\\{(.*)\\}");
  Matcher matcher = pattern.matcher(value);
  String content = null;
  if (matcher.find()) {
   if (Logger.DEBUG) {
    System.out.println("TemplatePropertyMaker: " + value.substring(matcher.start(), matcher.end()));
    System.out.println("TemplatePropertyMaker: " + matcher.group(1));
   }
   content = matcher.group(1);
  }
  
  if (content == null) {
   return null;
  }
  return content;
 }
 
 public static TemplateProperty getTemplatProperty(String key, String value) {
  String content = getGroup(value);
  Pattern pattern = Pattern.compile("(\\w++).(\\w++).(\\w++)");
  Matcher matcher = pattern.matcher(content);
  
  TemplateProperty templateProperty = new TemplateProperty();
  if (matcher.find()) {
   int number = matcher.groupCount();
   while (number > 0) {
    templateProperty.setValue(number, matcher.group(number));
    number--;
   }
  }
  templateProperty.setKey(key);
  return templateProperty;
 }
}
