1. Introduction

Sometimes, when we use redis in SpringBoot app, we got this Exception:

2. Environments

  • SpringBoot 1.x and 2.x

3. The solution

3.1 Increase the springboot redis connection timeout

You can increase the timeout of redis with this property:

spring.redis.timeout=30000 

This means the spring redis timeout is 30 seconds.

4. Summary

You can view the complete springboot properties from this document.
