# Java バージョン対応方法

## 問題

ビルドや実行時にJavaバージョンが合わない場合のエラー:

- `UnsupportedClassVersionError: has been compiled by a more recent version of the Java Runtime`
- `class file version 65.0` (Java 21) vs `class file version 61.0` (Java 17)

## 解決方法

JAVA_HOMEに適切なJavaバージョンをセットして実行する

### miseでインストールされたJavaを使用する場合

```bash
# Javaのパスを確認
mise which java
# 例: $HOME/.local/share/mise/installs/java/openjdk-21.0.2/bin/java

# JAVA_HOMEをセットして実行
export JAVA_HOME=$HOME/.local/share/mise/installs/java/openjdk-21.0.2 && ./gradlew bootRun
```

### プロジェクト要件

- **必要なJavaバージョン**: Java 21
- **ビルド時**: `./gradlew build -x detekt`
- **実行時**: `./gradlew bootRun`

### 注意事項

- プロジェクトはJava 21でコンパイルされているため、Java 21以降が必要
- miseでJava環境を管理している場合は、miseのJavaパスを使用する

# プライバシーとパス記述ルール【最重要】

## 絶対に守るべきルール

### ❌ 禁止事項

- **絶対にローカルパスを含めない**
- `/Users/username/`
- `/home/username/`
- 個人を特定できる具体的なユーザーパス

### ✅ 正しい記述方法

- **環境変数や抽象パスを使用**
- `$HOME`
- `~`
- `$USER_HOME$`
- `{Java インストールディレクトリ}`
- 相対パス

### 具体例

❌ 悪い例:

```
/Users/{username}/.local/share/mise/installs/java/
/Users/{username}/projects/KidsPOS-Server/
```

✅ 良い例:

```
$HOME/.local/share/mise/installs/java/
~/projects/KidsPOS-Server/
./relative/path/
```

## 理由

- **個人情報の保護**: ユーザー名などの個人情報を露出させない
- **セキュリティ**: システムパス情報の漏洩を防ぐ
- **ポータビリティ**: 他の環境でも動作する汎用的な記述

## 適用範囲

- コード内のパス
- ドキュメント
- コメント
- ログ出力
- エラーメッセージ
- メモリファイル
- **すべての出力において厳守**

The method silently ignores updates when the item doesn't exist. Consider returning an error response or throwing an exception when attempting to update a non-existent item to provide clearer feedback to users.

The log message should differentiate between create and update operations. Consider logging 'Creating store' for new stores and 'Updating store' for existing stores to improve debugging clarity.
