Spring Boot integrates Redis spring boot provides the spring data Redis library to integrate Redis operations, and realizes the integration with Redis through simple configuration information. PS: individuals are still used to using Jedis to operate Redis for Java clients Don't talk too much, just code. : -) Maven dependence <dependency&gt ...

Preface Recently, we are working on a smart home platform. Considering that the control of home needs fast response, we plan to use redis cache. On the one hand, it can reduce the pressure of database, on the other hand, it can improve the response speed. The technology stack used in the project is basically the familiar springboot family buck ...

Application scenarios: The home page is visited by a large number of people every day, which causes great pressure to access the database, even paralysis. So how to solve it? There are two ways we usually do this: one is data caching, the other is static web pages. *** Four issues considered before us ...

Let's first look at how java links redis Maven: <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>3.0.1</version> </dependency> Java: public static void ma ...

redis-cluster tutorial In the case of billiards projects, I want to write some information about users into the redis cache, because redis is stored in key-value mode. Let's save it. Who's afraid of who? import com.yuyuka.billiards.service.config.DiamondConfigurtion; import com.yuyuka.billiards.servic ...

Let's start by describing what problems would be caused to our cache in the case of high concurrency? 1. Cache Breakdown: In the case of high concurrency, when a hot key fails, a large number of requests will be made to access our data, such as when a commodity is killed in seconds. 2. Cache avalanche: refers to a time when a large number of ke ...

1. Concepts Idempotency, commonly referred to as an interface, makes the same request multiple times and must ensure that the operation can only be performed once For example: Order interface, order cannot be created more than once Payment interface, double payment of the same order can only be deducted once Alipay callback interface, may hav ...

Distributed-Redis-based Interface IP Current Limitation In order to prevent our interfaces from being accessed maliciously, for example, when someone accesses our interfaces frequently through JMeter tools, the interface response becomes slower or ...

Now that I've built a general project structure, I'm starting to write some necessary tool classes. Today I'll start with the redis application that I use.Redis has many applications in some projects, so I'm going to talk about spring's String RedisTemplate today.The function redis uses in this project is to cache some information about WeChat ...

First, let's look at Redis 1. Introduction to Redis Redis is completely open source, free of charge, complies with BSD protocol, and is a high-performance key-value database. Redis and other key - value caching products have three features: Redis supports data persistence, can save data in memory in disk, and can be loaded again when re ...
