The error message you're encountering suggests that there's an issue related to Hibernate, specifically `org.hibernate.ObjectNotFoundException`. This exception is thrown when Hibernate cannot find a row in the database corresponding to a given identifier. Error Breakdown 1. Version and Package Info: - Version: 2021-12-10 20:25:58 - Package Info: branch_smartbiv95_20200429 2. Error Trace: - The stack trace starts at `smartbi.framework.rmi.clientservice.execute` (line 154). - It continues through other methods until it reaches `smartbi.usermanager.usermanagermodule.getcurusersofrole` (line 2491). 3. Caused By: - The root cause is `org.hibernate.ObjectNotFoundException`: "no row with the given identifier exists: [smartbi.usermanager.user#47649]". Troubleshooting Steps: 1. Verify the Identifier: - Check if the identifier `47649` is correct and exists in the database. - Ensure that the entity type `[smartbi.usermanager.user]` matches the actual table name or entity class used in your application. 2. Database Consistency: - Verify the consistency of your database. Make sure that the expected data is present and up-to-date. - Check for any recent changes or deletions that might have affected the data. 3. Hibernate Configuration: - Review your Hibernate configuration to ensure that the mappings and settings are correct. - Check if there are any issues with lazy loading or session management. 4. Code Inspection: - Inspect the code around line 154 in `smartbi.framework.rmi.clientservice.execute` and line 2491 in `smartbi.usermanager.usermanagermodule.getcurusersofrole`. - Look for any potential issues with how entities are being loaded or referenced. 5. Logging and Debugging: - Enable more detailed logging for Hibernate to get insights into SQL queries and other operations. - Use debugging tools to step through the code and identify where the issue occurs. Example Code Snippet: Here's a simplified example of how you might load an entity using Hibernate and handle exceptions: ```java import org.hibernate.Session; import org.hibernate.Transaction; import org.hibernate.exception.ConstraintViolationException; import org.hibernate.objectnotfoundexception.ObjectNotFoundException; public class UserLoader { public static void main(String[] args) { Session session = HibernateUtil.getSessionFactory().openSession(); Transaction transaction = null; try { transaction = session.beginTransaction(); // Assuming you have a User entity User user = (User) session.get(User.class, 47649); if (user == null) { System.out.println("User not found."); } else { System.out.println("User found: " + user.getName()); } transaction.commit(); } catch (ObjectNotFoundException e) { System.err.println("Error: " + e.getMessage()); if (transaction != null) { transaction.rollback(); } } finally { session.close(); } } } ``` This snippet demonstrates how to load a `User` entity by ID and handle the `ObjectNotFoundException` gracefully. Adjust the code based on your specific requirements and entity types. [2024-08-22 09:19:51 | AI写代码神器 | 715点数解答]
