Question

在Gitlarunner上但不在本地运行测试时出现此错误，这是实现与mariadb的连接的代码

mariadb中的max_connection设置为100，我认为足够了吗？

您看到我的实施中有任何缺陷吗？

config.addDataSourceProperty("dataSource.prepStmtCacheSqlLimit", "2048");
        config.addDataSourceProperty("dataSource.useServerPrepStmts", "true");
        return new HikariDataSource(config);
    }
