Using the underlying API: RedisConnection operation of Redis requires manual conversion of data ( String ), which requires most repetitive work and is inefficient; org.springframework.data.redis.core.RedisTemplate classes provide a high level of abstraction for interacting with Redis, which is responsible for serialization and connection management, encapsulating most of the repetitive work. And RedisTempl

In the near term, the company took over a order number generation service, the rules have been set by the project manager, they are the main number of the following four-digit representative of the current order number has been executed the first few. And there is a requirement to support the distributed. In order to achieve this, I started using Redis's incr to solve this problem, because our backend development uses spring boot, so I found a code li

Redis is a very good caching framework, good API, strong performance, is now very very fire caching framework. Here's how to integrate Redis in springAnalysis: Need to introduce dependency You need to configure the connection pool, which is an XML file, and then the parameters are written in the properties Need to write a tool class, the main method is to get

first, and after close () calls the Close () method, which is equivalent to generating a new session instance, so we do not have to manually close the session (), It is also not possible to use MyBatis's first-level cache, which means that MyBatis's first-level cache does not work in spring. Therefore, we generally implement the MyBatis level two cache in the project, although MyBatis comes with a level two cache function, but if the actual cluster e

In Spring Data Redis 1.x , we might write such a redisconfig class in the project:@Configuration @enablecaching Public classRedisconfig {@SuppressWarnings ({"Rawtypes", "unchecked"}) @Bean (name= "Redistemplate") Publicredistemplate initredistemplate () {jedispoolconfig poolconfig=NewJedispoolconfig (); //Maximum idle numberPoolconfig.setmaxidle (50); //Maximum number of connectionsPoolconfig.setmaxtota

Function Introduction Most of the users like to use Redistemplate, and its corresponding package is org.springframework.data.redis.core. The template is actually the core class of the Redis module because of its rich functionality. Templates provide a high level of abstraction for redis interactions. Although Redisconnection provides a low-level way to accept and return binary values (byte arrays), the te

Redis is operating in 1.spring, key is added and keys seen in the console are serialized2. As "\xac\xed\x00\x05t\x00\x12signrule2014-09-28", the actual key we added is signrule2014-09-283. Therefore, we cannot directly modify the value of the key with a script or command via a known key.4. You can use JSP to get or modify the value of Redis@page Import="org.sprin
