Getter Template with Optional<> for IntelliJ IDEA

If you are working with Java 8 and Intellij IDEA, good practice to use Optional for getters, of course depending on logic as well. I’ll show how to quick configure IDE for generation such getters

Create new template and place this code:

#if($field.modifierStatic)
static ##
#end
Optional<$field.type> ##
#set($name = $StringUtil.capitalizeWithJavaBeanConvention(
$StringUtil.sanitizeJavaIdentifier(
$helper.getPropertyName($field, $project))))
#if ($field.boolean && $field.primitive)
  is##
#else
  get##
#end
${name}() {
  return Optional.ofNullable($field.name);
}
