Question

我有一个我想在Drools 6.0.1决策表中使用的类，它不在默认的类加载器中。我创建了一个自定义类加载器，我想在Drools中使用，但我只能找到KieBaseConfiguration类来设置它。这似乎没有对返回“无法找到类”错误的KieBuilder产生影响。如何为构建器设置类加载器？

代码如下：

// Create the classloader and make sure the class is available.
ClassLoader loader = getClassLoader();
Class<?> clazz = loader.loadClass("actions.TestAction");

// Create the model
KieServices kieServices = KieServices.Factory.get();
KieModuleModel kieModuleModel = kieServices.newKieModuleModel();
KieBaseModel kieBaseModel1 = kieModuleModel.newKieBaseModel( "KBase1")
    .setDefault( true )
    .setEqualsBehavior( EqualityBehaviorOption.EQUALITY )
    .setEventProcessingMode( EventProcessingOption.STREAM );
KieSessionModel model = kieBaseModel1.newKieSessionModel( "KSession1" )
    .setDefault( true )
    .setType( KieSessionModel.KieSessionType.STATELESS )
    .setClockType( ClockTypeOption.get("realtime") );

// Create a new configuration with the new classloader. Does not seem to 
// do anything with regard to rule compilation.
KieBaseConfiguration kbaseConf = 
                kieServices.newKieBaseConfiguration( null, loader );

// Create a file system and load the rule.
KieFileSystem kfs = kieServices.newKieFileSystem();
String decisionTable = 
    ",RuleSet,\n"+
    ",Import,conditions.test.TestCondition\n"+
    ",Sequential,TRUE\n"+
    ",,\n"+
    ",RuleTable System Table,\n"+
    ",CONDITION,ACTION\n"+
    ",TestCondition,testAction\n"+
    ",conditionID,test(\"$param\")\n"+
    "Case,Table,Log\n"+
    "Test,10027,Random Text\n"+
    ",,\n"+
    ",,\n"+
    ",Variables,actions.TestAction testAction\n";
kfs = kfs.write("src/main/resources/KBase1.csv", decisionTable);

// Build the rules. I get a compilation error here, actions.TestAction class 
// not found.
KieBuilder kieBuilder = kieServices.newKieBuilder(kfs).buildAll();

用自定义类加载器Drools 6
