Drools规则插入新事实，并解雇其他规则动态

Question

我是Drools和Kie-Server的新手。我对如何通过射击规则RHS(然后操作(在工作记忆中插入新事实的问题有问题，然后通过这些动态传递的事实激活其他规则。

我期望的是，当底部基础从外部插入工作记忆并激活Ruleone，在Ruleone内部"然后"它将插入新事实的luleresult，并期望激活Ruletwo，但是它不会激活Ruletwo，只是Ruleone，被激活了，我做错了吗？

在这里，我有两个规则和一组事实：

事实定义：

public class AppResult implements java.io.Serializable
{
   static final long serialVersionUID = 1L;
   private java.lang.String key;
   private java.lang.String value;
   //getters and setters ...
}

public class BaseFeature implements java.io.Serializable
{
   static final long serialVersionUID = 1L;
   private int age;
   //getters and setters ...
}
public class RuleResult implements java.io.Serializable
{
   static final long serialVersionUID = 1L;
   private java.lang.String ruleName;
   private java.lang.Long score;
   private boolean state;
   //getters and setters ...
}

规则定义：

rule "RuleOne"
    dialect "mvel"
    salience 100
    no-loop true
    lock-on-active true
    when
        $b : BaseFeature( age < 22 || age > 40 )
    then
        RuleResult $r = new RuleResult();
        $r.setRuleName( "RuleOne" );
        $r.setState( false );
        insertLogical( $r );
end
rule "RuleTwo"
    dialect "mvel"
    no-loop false
    lock-on-active true
    salience 10
    when
        $r : RuleResult( ruleName == "RuleOne" , state == false )
        $a : AppResult( )
    then
        $a.setKey( "PASS" );
        $a.setValue( "false" );
end

如何实现射击规则插入新事实并解雇其他规则动态？预先感谢！

它的期望是：

Answer 1

如果您不知道这些规则属性的目的，则应阅读文档。然后，我认为，您会意识到您可以删除它们。

salience 100 or 10
no-loop true or false
lock-on-active true

Answer 2

我同意Laune的同意，您应该阅读规则属性的含义(请参见文档[1]中的ERE(。我认为这是因为您对规则有锁定。请查看我链接的文档。

Answer 3

尝试使用更新功能"

然后

    RuleResult $r = new RuleResult();
    $r.setRuleName( "RuleOne" );
    $r.setState( false );
    update ( $r );
