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

顺便写了个工具类配合SpringBoot使用:

package com.ciih.refineinner.cache;
import com.github.benmanes.caffeine.cache.Cache;
import com.github.benmanes.caffeine.cache.Caffeine;
import org.springframework.stereotype.Component;
import java.util.concurrent.TimeUnit;
import java.util.function.Function;
/**

@Component
public class CaffeineService {
    private Cache<String, String> cache;
    public CaffeineService() {
        this.cache = Caffeine.newBuilder()
                .expireAfterWrite(15, TimeUnit.MINUTES)
                .maximumSize(100)
                .build();
    }
    /**
     * 存储K-V
     *
     * @param key
     * @param value
     * @return
     */
    public String put(String key, String value) {
        cache.put(key, value);
        return key;
    }
    /**
     * 获取K-V
     *
     * @param key
     * @return
     */
    public String getIfPresent(String key) {
        return cache.getIfPresent(key);
    }
    public String get(String key, Function<String, String> function) {
        return cache.get(key, function);
    }
    public void remove(String key) {
        cache.invalidate(key);
    }
}
