IDEA添加非空Getter方法模板

#if($field.modifierStatic)
static ##
#end
$field.type ##
#set($name = $StringUtil.capitalizeWithJavaBeanConvention($StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($field, $project))))
#if ($field.boolean && $field.primitive)
is##
#else
get##
#end
${name}() {
## 常用类型
#if($field.isString())
    $field.name = Optional.ofNullable($field.name).orElse("");
#elseif($field.isList())
    $field.name = Optional.ofNullable($field.name).orElse(new ArrayList<>());
#elseif($field.isSet())
    $field.name = Optional.ofNullable($field.name).orElse(new HashSet<>());
#elseif($field.isMap())
    $field.name = Optional.ofNullable($field.name).orElse(new HashMap<>());
## 如果是基本类型，则什么都不做
#elseif($field.numeric||$field.boolean||$field.byte||$field.char||$field.getTypeName() == "Character")
##用户自定义类型或以上未包含类型，直接new
#else
    $field.name = Optional.ofNullable($field.name).orElse(new $field.getTypeName()());
#end
return $field.name;
}
