liteflow 更适应我们的项目使用了它
drools 感觉复杂度高些

业务中是否写了大量的 if-else?是否受够了这些 if-else 还要经常变动? 业务中是否做了大量抽象,发现新的业务场景还是用不上? 是否各种调研规则引擎,发现不是太重就是接入或维护太麻烦,最后发现还是不如硬编码? 接下来给大家介绍一款全新的开源规则引擎——ice,以一个简单的例子,从最底层的编排思想,阐述 ice 与其他规则引擎的不同;讲述 ice 是如何使用全新的设计思想,契合解耦和复用的属性,还你最大的编排自由度。

scan: com.ice.test #用于扫描叶子节点,多个包用','分隔(默认扫描全部,扫描全部会拖慢应用启动速度)
pool: #线程池配置(用于并发关系节点)
parallelism: -1 #默认-1,≤0表示采用默认配置
新增 ICE
当 recharge 发生的时候触发
