Check the database performance, optimize the query, increase the index, expand the connection pool and adjust the timeout time; 2. Reasonably extend the timeout settings in the program according to actual needs, but should not blindly increase; 3. Check the network stability and remote service response to ensure smooth interface calls; 4. Adopt asynchronous processing and queue mechanisms to avoid blocking the main thread for a long time. These steps can effectively locate and resolve timeout issues.
