在Drools Planner中创建实时规则 [英] Live rule creation in Drools Planner

问题描述

我对为Drools Planner创建规则感兴趣.我希望用户可以在启动Drools Planner之前在Java应用程序中创建自己的规则.用户添加规则后，可能会生成Drools-rule-file. 这可能吗?还是在开发整个Java应用程序时必须创建规则文件?

I am interested in creating rules for Drools Planner. I want that a user can create his own rules in a java app before starting the Drools Planner. Maybe a Drools-rule-file could be generated after the user has added his rules. Would this be possible or do I have to create the rule-file while developing the whole java application?

非常感谢...

推荐答案

是的. 诀窍是构建自己的RuleBase并将其设置在Planner配置中. 请参阅"5.3节". 4.2.2.手册中的"RuleBase(可能由Guvnor定义)".

Yes it's possible. The trick is to build your own RuleBase and set it in the Planner config. See section "5.3.4.2.2. A RuleBase (possibly defined by Guvnor)" in the manual.

根据您希望用户如何编辑他/她的规则，您可以用几个来构造RuleBase:

You can construct a RuleBase by several, depending on how you want your user to edit his/her rules:

• 来自DRL文件.假定用户知道DRL.请参阅Drools Expert手册.
• 来自DSL文件.这使您可以使用自然语言.
• 通过guvnor网络应用.这样一来，您就可以使用Guvnor工具，例如指导规则编辑器，决策表电子表格等等.您甚至可以使用变更集.
• 从Eclipse中的guvnor或独立的应用程序中(正在开发和实验中).这个领域有一些工作，但还很年轻.

• From a DRL file. This presumes the user knows DRL. See Drools Expert manual.
• From a DSL file. This allows you to use natural language.
• From the guvnor webapp. This allows you to use the tooling Guvnor, such as a guided rule editor, a decision tables spreadsheet, ... You can even use a changeset.
• From guvnor in eclipse or a standalone app (under development and experimental). There's some work being in this area, but it's still young.
