JBoss Drools 工作记忆的多项事实

这是我的规则：

rule "Your First Rule"

    when
        $testRule : TestRule(count >= 100)
    then 
        System.out.println("100 PACKETS!");
    end

这就是我创建 RuleBase 和工作内存的方式：

public void invokeRules(){
    RuleBase ruleBase = readRule(); \\creates ruleBase from DRL package
    workingMemory = ruleBase.newStatefulSession();
    testRule = new TestRule();
    factHandle = workingMemory.insert(testRule);    
    workingMemory.fireAllRules();
}

我有一个更新部分：

workingMemory.update(factHandle, testRule);

我现在在工作内存中获取 1 个 TestRule 事实，并且该规则正在创建 TestRule 的另一个实例。我知道我正在实例化两个 TestRule 事实，但只有工作内存中的一个做出反应。我哪里错了？！

（无计可施）

This is my rule:

rule "Your First Rule"

    when
        $testRule : TestRule(count >= 100)
    then 
        System.out.println("100 PACKETS!");
    end

This is how I create the RuleBase and WorkingMemory:

public void invokeRules(){
    RuleBase ruleBase = readRule(); \\creates ruleBase from DRL package
    workingMemory = ruleBase.newStatefulSession();
    testRule = new TestRule();
    factHandle = workingMemory.insert(testRule);    
    workingMemory.fireAllRules();
}

I have an update section:

workingMemory.update(factHandle, testRule);

I am now getting 1 TestRule fact in WorkingMemory and the rule is creating another instance of TestRule. I am aware that I am instantiating two TestRule facts but only the one in WorkingMemory reacts. Where am I going wrong?!
