drools。drools_使用Drools跟踪输出

發布時間：2023/12/3 编程问答 31 豆豆

生活随笔收集整理的這篇文章主要介紹了 drools。drools_使用Drools跟踪输出小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

drools。drools

Drools 6包含一個跟蹤輸出，可以幫助您了解系統中正在發生的事情，事物執行的頻率以及多少數據。

這也有助于理解Drools 6現在是基于目標的算法，它使用鏈接機制鏈接評估規則。有關此的更多詳細信息：

http://www.javacodegeeks.com/2013/11/rip-rete-time-to-get-phreaky.html

首先要做的是將slf4j記錄器設置為跟蹤模式：

讓我們以購物為例，您可以在這里找到Java和Drl文件：

https://github.com/droolsjbpm/drools/blob/master/drools-examples/src/main/resources/org/drools/examples/shopping/Shopping.drl
https://github.com/droolsjbpm/drools/blob/master/drools-examples/src/main/java/org/drools/examples/shopping/ShoppingExample.java

運行該示例將為輸出提供非常詳細且冗長的執行日志。最初，您將看到插入的對象，這會導致鏈接。在Drools 6算法鏈接中說明了節點和規則的鏈接。總結1..n節點在插入對象時鏈接在一個段中。

2014-10-02 02:35:09,009 [main] TRACE Insert [fact 0:1:1455177644:1455177644:1:DEFAULT:NON_TRAIT:org.drools.examples.shopping.ShoppingExample$Customer@56bc3fac] 2014-10-02 02:35:09,020 [main] TRACE LinkNode notify=false nmask=1 smask=1 spos=0 rules=

然后1..n段鏈接到規則中。當一個規則被鏈接時，它就在議程上以進行評估。

2014-10-02 02:35:09,043 [main] TRACE LinkRule name=Discount removed notification 2014-10-02 02:35:09,043 [main] TRACE Queue RuleAgendaItem [Activation rule=Discount removed notification, act#=0, salience=0, tuple=null] 2014-10-02 02:35:09,043 [main] TRACE Queue Added 1 [Activation rule=Discount removed notification, act#=0, salience=0, tuple=null]

當它最終評估規則時，它將在訪問每個節點時縮進，從根到末端進行評估。每個節點將嘗試告訴您此時要插入，更新或刪除多少數據。

2014-10-02 02:35:09,046 [main] TRACE Rule[name=Apply 10% discount if total purchases is over 100] segments=2 TupleSets[insertSize=1, deleteSize=0, updateSize=0] 2014-10-02 02:35:09,047 [main] TRACE 1 [ AccumulateNode(12) ] TupleSets[insertSize=1, deleteSize=0, updateSize=0] 2014-10-02 02:35:09,047 [main] TRACE Segment 1 2014-10-02 02:35:09,047 [main] TRACE 1 [ AccumulateNode(12) ] TupleSets[insertSize=1, deleteSize=0, updateSize=0] 2014-10-02 02:35:09,047 [main] TRACE rightTuples TupleSets[insertSize=2, deleteSize=0, updateSize=0] 2014-10-02 02:35:09,056 [main] TRACE 2 [RuleTerminalNode(13): rule=Apply 10% discount if total purchases is over 100] TupleSets[insertSize=1, deleteSize=0, updateSize=0]

您可以使用此信息來查看規則評估的頻率，進行鏈接和取消鏈接的次數，傳播的數據量以及更重要的是浪費了多少工作。這是完整的日志：
