OverviewRedisTemplateThe default is to use a serializer based on JDK , so the data stored in if it is Redis not deserialized, see the result is like this:Can see, there is garbled, at the program level, will not affect the operation of the program, but when the data errors, the data to troubleshoot, will not be able to.SerializerIn spring Data Redis, the conversi

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

With the latest Jedis-2.6.2.jar This bag, this is a little different from the previous one. You will also need to add Spring-data-redis-1.2.1.release.jar and Commons-pool2-2.3.jar.Create a Spring-redis-config.xml file under the ClasspathXML version= "1.0" encoding= "UTF-8"?> Beansxmlns= "Http://www.springframework.org

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
