springboot集成caffeine缓存的详细过程

Sure, I can help you with the integration of Caffeine cache with Spring Boot. Here are the steps:

1. Add the Caffeine dependency in your pom.xml file:

<dependency>
    <groupId>com.github.ben-manes.caffeine</groupId>
    <artifactId>caffeine</artifactId>
    <version>2.9.0</version>
</dependency>

2. Create a Caffeine cache manager bean in your Spring Boot application:

@Bean
public CaffeineCacheManager caffeineCacheManager() {
    CaffeineCacheManager caffeineCacheManager = new CaffeineCacheManager();
    caffeineCacheManager.setCaffeine(Caffeine.newBuilder().expireAfterWrite(5, TimeUnit.MINUTES));
    return caffeineCacheManager;
}

Here, we are setting the cache to expire after 5 minutes of being written to.

3. Use the cache in your Spring Boot application by adding "@Cacheable" annotation to the method where you want to cache the result:

@Cacheable("myCache")
public String getData(String key) {
    // code to fetch data
}

That's it! Now, when the "getData" method is called with the same key, the result will be fetched from the cache instead of executing the method again.
