What should be done when Spring Framework is unable to resolve?

If you encounter any issues that Spring Framework cannot resolve, you can try the following methods to solve them:

1. Ensure that the relevant dependencies of the Spring Framework are correctly imported into the project: Review the project’s Maven or Gradle configuration files to make sure that the dependencies of the Spring Framework have been added correctly.
2. Check the compatibility of the Spring Framework version: If other dependencies or frameworks are used in the project, it may cause Spring Framework to be unable to resolve. For example, if a dependency package requires an older version of Spring Framework, while the project uses a newer version of Spring Framework. You can try adjusting the version of the dependency package to resolve the compatibility issue.
3. Check the project configuration file to ensure that the project’s configuration file (such as application.properties or application.yml) has correctly configured Spring Framework related configuration items. For example, database connection configuration, package scanning path configuration, etc.
4. Check the classpath configuration: If a custom classpath configuration is used in the project, verify that it is correct and ensure that the relevant Spring Framework classes can be loaded properly.
5. Check for code issues: If none of the above methods can solve the problem, it may be due to errors or improper coding in the code causing Spring Framework to be unable to resolve. You can carefully inspect the code, especially annotations, configurations, etc. related to Spring Framework.

If the above methods still do not resolve the issue, you can review the specific error messages, consider seeking help in a search engine or developer community, or try recreating a new Spring Framework project to eliminate interference from other factors.
