Springboot Integrated Redis First practice

　Redis is an open source (BSD licensed), memory-stored data structure server that can be used as a database, cache, and Message Queuing agent.

Sometimes, in order to improve the performance of the entire Web site, the data that is frequently accessed is cached at development time, which can improve the efficiency of data loading when the data interface is called.

This article will integrate Redis in the boot project, caching common data to REDIS servers and improving the concurrency of common services.

Project Environment:

jdk1.8

maven3.5

Spring Boot 2.0.4.RELEASE

Spring-boot-starter-data-redis 2.0.4.RELEASE

Redis3.2

I. Installing Redis

Follow "Terry's private Tutorial" public number reply Redis get

　　Unzip to local open Redis-cli.exe run after download

　　

After a successful run, you can view it through the Redis Desktop Manager connection

　　

Two. Integrated Redis

This project caches data in Redis when invoking weather interface data

Specific implementation:

Introduction of stringredistemplate, increased operation on Redis servers

Set Cache time

　　

redis is stored in key-value format, so calling This method will call the address as key, call data value, each call is first to determine if there is a key in Redis, if there is this key, Direct else will pull the data out,

Re-fetch the data if it does not exist and initialize it to Redis

　　

Third, the results of the operation

Logs allow you to discover that data is being cached in the Redis server

　　

　　through Redis Desktop Manager View

　Integrated Redis success, if you have questions, please follow the public number "Terry Private tutorial" message
