Spring cloud和规则引擎urule整合代码
Spring cloud和规则引擎urule整合代码
本章内容其实和spring cloud没大关系，需要注册中心代码的参考前面的文章：https://blog.csdn.net/rishengcsdn/article/details/89956473
urule规则引擎是一套纯Java实现，运行时借鉴Rete了算法的优势，再结合中式规则引擎的特点，独创了一套自己的规则模式匹配算法的系统，参考文档：
http://www.bstek.com/resources/doc/
下面讲项目代码结构：
项目基于Spring Cloud的框架，整合了Urule2.1.2版本的控制中心。源码下载链接：

项目启动成功后访问：http://localhost:8087/
就可以看到规则引擎首页了
具体配置规则就是拖拖拽拽，修改一些参数，这里就不详细说明了，为了避免麻烦我建议导入我的备份文件测试项目例子-urule-repo-20190520105757.bak，导入和导出可以用在测试环境到生产环境的部署上。
导入成功后应该可以看到已经编辑好的知识包，变量库，向导式决策等等文件。
这个是变量库，对应于java代码的Bbb.java，代表一个业务实体。
然后是一个简单规则：
规则导入后，还是需要在知识包的界面上重新发布一下，刷新规则到内存。最好，在界面上仿真测试一下规则。
最后，通过浏览器访问ctrl类，http://localhost:8087/test/testRule?bb1=15&bb2=15，
获得结果如下：
规则引擎
高性能、便捷
图形化建模、仿真测试
结果为正确
修改业务参数：http://localhost:8087/test/testRule?bb1=3&bb2=15
获得结果如下：
规则引擎
高性能、便捷
图形化建模、仿真测试
结果不对啊
相对于drools引擎，urule显得轻便很多，rest接口实现可以参考我的UruleController.java的testRuleRest()方法。
