@Getter
@Setter
@Configuration
@ConfigurationProperties("system.cache.caffeine")
@ConditionalOnProperty(prefix = "system.cache.caffeine" , name = "enabled", havingValue = "true")
public class CaffeineCacheProperties {
  private List<String> cacheName;
  private Duration expireAfterWrite;
  private Duration expireAfterAccess;
  private Long maximumSize = Long.valueOf(-1);

  @Getter
  @Setter
  public static class Config {
    private List<String> cacheName;
    Duration expireAfterWrite;
    Duration expireAfterAccess;
    Long maximumSize;
  }
}

application.yml

system.cache.caffeine:
 enabled: true
 # 全局配置
 cacheName: cache1,cache2,cache3
 expireAfterWrite: 60s
 expireAfterAccess: 30s
 maximumSize: 500
 # 自定义配置，cacheName相同可覆盖全局
 configs:
 - cacheName: checkApplyCache
  expireAfterAccess: 10s
 - cacheName: userQueryCache
  expireAfterAccess: 15s

使用缓存

@Cacheable(value = { "checkApplyCache" }, key="#req.md5")
public Result check(CheckReq req) {
  // your code...
  return Result.ok();
}
