Most people do not understand the knowledge points of this article "how to integrate SpringBoot into Redisson", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this article "how to integrate Redisson with SpringBoot in Micro Services Framework".

Comparison of advantages and disadvantages of Redisson, Jedis and Lettuce

(1) Redisson

Advantages:

The distributed characteristics and extensible Java data structure are realized, which is suitable for distributed development.

API thread safety

Event-driven communication based on Netty framework, which can be called asynchronously.

Disadvantages:

API is more abstract and expensive to learn to use.

(2) Jedis

Advantages:

API that provides more comprehensive operational features of Redis

API basically corresponds to the instructions of Redis, which is easy to use and easy to understand.

Disadvantages:

Synchronous blocking IO

Asynchrony is not supported

Thread is not safe.

(3) Lettuce

Advantages:

Thread safety

Event-driven communication based on Netty framework, which can be called asynchronously

Suitable for distributed caching.

Disadvantages:

API is more abstract and expensive to learn to use.

Among them, Jedis is the most commonly used (indeed very simple), especially for many single applications or pseudo-distributed applications.

SpringBoot integrates Redisson

1. Add Maven dependency org.redisson redisson-spring-boot-starter 3.11.4 2. Configuration file spring: redis: host: 127.0.0.1 port: 6379 database: 0 timeout: 50003. Add configuration class import org.redisson.Redisson;import org.redisson.api.RedissonClient;import org.redisson.config.Config;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.autoconfigure.data.redis.RedisProperties;import org.springframework.boot.context.properties.EnableConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class RedissonConfig {@ Autowired private RedisProperties redisProperties; @ Bean public RedissonClient redissonClient () {Config config = new Config () String redisUrl = String.format ("redis://%s:%s", redisProperties.getHost () + ", redisProperties.getPort () +"); config.useSingleServer (). SetAddress (redisUrl) .setPassword (redisProperties.getPassword ()); config.useSingleServer (). SetDatabase (3); return Redisson.create (config);}} 4. Code testing (simple access) import org.redisson.api.RedissonClient;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.StringRedisTemplate;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping ("/ redisson") public class RedissonController {@ Autowired private StringRedisTemplate stringRedisTemplate @ GetMapping ("/ save") public String save () {stringRedisTemplate.opsForValue () .set ("key", "redisson"); return "save ok";} @ GetMapping ("/ get") public String get () {return stringRedisTemplate.opsForValue () .get ("key") }} the above is the content of this article on "how SpringBoot integrates Redisson".
