HikariPool PoolInitializationException @Testメソッドが追加されたとき

私はHikariCP2.6.1で作業しています。HikariPool PoolInitializationException @Testメソッドが追加されたとき

MySQLとJUnit 4.xを安心して使用しています。ちょうど今日、私は新しい@Testメソッドを追加しましたが、テストは失敗します。私がをこの新しい@Testに当てはめると、もちろんすべてが再び機能します。 @Ignoreを他の先に置き換えた場合@Testにはが渡され、この新しい@Testにはすべて@Ignoreが削除されます。

そこでDB接続は次の例外が発生する作品以上が必要です。この新しい@Test方法の追加：

Caused by: org.springframework.beans.BeanInstantiationException:

    at com.mysql.cj.mysqla.io.Buffer.readInteger(Buffer.java:271)

私の現在の設定は次のとおりです。

@Bean(destroyMethod = "close") 
public DataSource dataSource() throws SQLException { 

    HikariConfig hc = new HikariConfig(); 

    hc.setDriverClassName(environment.getProperty("mysql.driverClass")); 
    hc.setJdbcUrl(environment.getProperty("mysql.jdbcUrl")); 
    hc.setUsername(environment.getProperty("mysql.user")); 
    hc.setPassword(environment.getProperty("mysql.password")); 

    hc.setPoolName(environment.getProperty("hikaricp.poolName")); 

    hc.addDataSourceProperty("databaseName", environment.getProperty("hikaricp.databaseName")); 
    hc.addDataSourceProperty("cachePrepStmts", environment.getProperty("hikaricp.cachePrepStmts")); 
    hc.addDataSourceProperty("prepStmtCacheSize", environment.getProperty("hikaricp.prepStmtCacheSize")); 
    hc.addDataSourceProperty("prepStmtCacheSqlLimit", environment.getProperty("hikaricp.prepStmtCacheSqlLimit")); 
    hc.addDataSourceProperty("useServerPrepStmts", environment.getProperty("hikaricp.useServerPrepStmts")); 

    HikariDataSource hds = new HikariDataSource(hc); 

    return hds; 
}

そして

hikaricp.poolName = "hikaricp-channels-pool" 
hikaricp.databaseName = batch 
hikaricp.cachePrepStmts = true 
hikaricp.prepStmtCacheSize = 250 
hikaricp.prepStmtCacheSqlLimit = 2048 
hikaricp.useServerPrepStmts = true 

mysql.user = root 
mysql.password = somepassword 
mysql.driverClass = com.mysql.cj.jdbc.Driver 
mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?autoReconnect=true&useSSL=false

追加の設定にはどのようなものが必要ですか？

アルファ

版01：

から：mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?autoReconnect=true&useSSL=false
へ：mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?useSSL=false

版02：

を追加しました：hc.addDataSourceProperty("maximumPoolSize", 2);DEBUGレポートについて

は今だけ変更：

//hc.addDataSourceProperty("maximumPoolSize", 2); 
    hc.setMaximumPoolSize(2);

すべてが今渡します。

この経験から、現在のドキュメントを改善するための提案をGitHubを通していくつかの「問題」を生じさせます。

私はあなたが間違いなく望んでいないと思います自動返信。また、テストの場合は、おそらくプールサイズが10である必要はありません.1または2を試してください。また、com.zaxxer.hikariのDEBUGロギングを有効にして、プールがテスト間で適切にシャットダウンされていることを確認してください。

「アルファ」セクションが追加されました。ちょうど興味があり、なぜ「2」で動作し、「10」で失敗するのか混乱します。 –
