這裡我們使用 `SessionDep` 依賴（即一個 `Session`），把新的 `Hero` 加入 `Session` 實例，提交變更到資料庫，刷新 `hero` 的資料，然後回傳它。

### 讀取多個 Hero { #read-heroes }

我們可以用 `select()` 從資料庫「讀取」多個 `Hero`。可以加入 `limit` 與 `offset` 來分頁。

### 讀取單一 Hero { #read-one-hero }

我們可以「讀取」單一的 `Hero`。

        StringBuilder sb1 = new StringBuilder("first");
        StringBuilder sb2 = new StringBuilder("second");
        String result = StringUtil.join(",", sb1, sb2);
        assertEquals("first,second", result);
    }

    @Test
    @DisplayName("Should handle StringBuffer as CharSequence")
    void testJoinWithStringBuffer() {

   * @param second the second array of elements to concatenate
   * @param type the component type of the returned array

      T[] first, T[] second, Class<@NonNull T> type) {

    arraycopy(first, 0, result, 0, first.length);

ここでは `SessionDep` 依存関係（`Session`）を使って、新しい `Hero` を `Session` インスタンスに追加し、データベースにコミットし、`hero` のデータをリフレッシュしてから返します。

### Hero の取得 { #read-heroes }

`select()` を使ってデータベースから `Hero` を取得できます。結果のページネーションのために `limit` と `offset` を含められます。
