jopen 13年前發布 | 21K 次閱讀 Java

       Drools（JBoss Rules ）具有一個易于訪問企業策略、易于調整以及易于管理的開源業務規則引擎，符合業內標準，速度快、效率高。業務分析師或審核人員可以利用它輕松查看業務規則，從而檢驗是否已編碼的規則執行了所需的業務規則。
JBoss Rules 的前身是Codehaus的一個開源項目叫Drools。最近被納入JBoss門下，更名為JBoss Rules，成為了JBoss應用服務器的規則引擎。
Drools是為Java量身定制的基于Charles Forgy的RETE算法的規則引擎的實現。具有了OO接口的RETE,使得商業規則有了更自然的表達。

JBoss Drools 5.3 新特性：

This is the last release where compatibility in core/compilier and other submodules will be maintained, as we refactor for cleanliness in the following releases. All developers should be using the knowledge-api.

Queries and Backward Chaining have had extensive bug fixing as it had many cases that didn't work, especially with "open" queries. Anyone using backward chaining queries in 5.2 should stop straight away and start using this.

</div> </div>

5.3 Introduces the declarative agenda, where rules can be used to control which rules can fire and when. While this will add a lot more overhead than the simple use of salience, the advantage is it is declarative and thus more readable and maintainable and should allow more use cases to be achieved in a simpler fashion.

This feature is off by default and must be explicitly enabled, that is because it is considered highly experimental for the moment and will be subject to change.
