Consider upgrading or downgrading the MySQL version, and install the latest stable version after backing up the data. 5. Check the firewall settings to ensure that the MySQL port is allowed to pass. 6. Check the system update log and deal with compatibility issues with dependency libraries or system components. 7. Ensure sufficient hard disk space and avoid insufficient data directory space. 8. If all the above methods are ineffective, seek professional help, such as M

VSCode was chosen to develop SpringBoot projects because of its lightweight, flexibility and powerful expansion capabilities. Specifically, 1) Ensure the environment is configured correctly, including the installation of JavaJDK and Maven; 2) Use SpringBootExtensionPack to simplify the development process; 3) Manually configure SpringBoot dependencies and configuration files, which requires a deep understanding of SpringBoot; 4) Use VSCode's debugging and performance analysis tools to improve development efficiency. Although manual configuration is required, VSCode provides a high level of custom space and flexibility.
