多模块项目使用枚举配置spring-cache缓存方案详解

public interface ICacheConfig {
    Integer getTtl();
}

@lombok.Getter

@lombok.experimental.FieldNameConstants(onlyExplicitlyIncluded = true)
public enum CommonCacheConfig implements ICacheConfig {
    @FieldNameConstants.Include QUOTE_LEVEL(1000, 2);
    private final Integer ttl;
}
