Java應用程序無法在Linux環境中登錄

Question

我寫了一個cron，它應該建立數據庫連接並進行一些更新和刪除操作。 cron使用批處理文件在Windows中運行良好，但失敗：

在代碼中，活動完成后，我正在使用StandardServiceRegistry關閉操作：

 String url="jdbc:mysql://"+arg[0]+":"+arg[1]+"/updatedb";
 AnnotationConfiguration config = new AnnotationConfiguration().configure();

 config.setProperty("hibernate.connection.url", url);
 config.setProperty("hibernate.connection.username", arg[2]);
 config.setProperty("hibernate.connection.password", arg[3].trim());

 StandardServiceRegistry registry = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();

 SessionFactory sessionFactory = config.buildSessionFactory(registry);

我正在使用.sh文件運行上述cron。 使用命令行可以正常運行，但是使用.sh文件運行時會遇到錯誤。 任何線索:(

您必須在MySQL命令解釋器上運行此命令。

GRANT ALL PRIVILEGES ON updatedb.* TO 'user01'@'%' WITH GRANT OPTION;

這將授權user01從任何主機進行連接。
