How to handle abnormal visits to Redis

When accessing Redis, there may be exceptions that occur. Here are some methods to handle exceptions:

1. Using a try-catch block to catch exceptions allows you to handle the exceptions in the catch block, such as logging, reconnecting to Redis, etc.
2. When connecting to Redis, setting an appropriate timeout can prevent prolonged blocking due to network or server issues.
3. By using a connection pool to manage connections, it is possible to effectively handle connection resources and avoid the frequent creation and destruction of connections.
4. For common exceptions like connection timeout or disconnection, you can add corresponding retry logic in the code to attempt reconnecting with Redis.
5. For some irrecoverable exceptions, such as issues with the Redis server, appropriate handling methods can be chosen based on the specific situation, such as degradation handling or returning error codes.
