私はApache JMeterでSpring MVC Webアプリケーションをテストしていますが、h2dbプール接続にはいくつか問題があります。壊れた接続の理由
私のテストは5つのスレッドと100のループで構成されています。私はglassfishサーバー上の登録フローをテストします。 まずデータベース接続クラスとしてorg.springframework.jdbc.datasource.DriverManagerDataSourceを使用しましたが、テストの途中で接続が中断されました。今、私は以下のパラメータを持つDBCPを使用します：
<property name="initialSize" value="1"/>
<property name="maxActive" value="100"/>
<property name="maxIdle" value="10"/>
残念ながらテストはまだ中断されています。私は得る：
