我需要在运行时添加.drl文件（来自S3存储桶），并将其提供给drools规则引擎

无法在运行时通过ResourceFactory.newURLResource（）添加规则 此外，KnowledgeBase已弃用或无法解析

我已经尝试了文档中的所有片段

公共类规则管理器{

public RuleRunner() {
}

public void runRules(String[] rules,
                     Object[] facts) throws Exception {

    KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

    for ( int i = 0; i < rules.length; i++ ) {
        String ruleFile = rules[i];
        System.out.println( "Loading file: " + ruleFile );
        kbuilder.add( ResourceFactory.newClassPathResource( ruleFile,
                                                            RuleRunner.class ),
                      ResourceType.DRL );
    }

    Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages();
    kbase.addKnowledgePackages( pkgs );
    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

    for ( int i = 0; i < facts.length; i++ ) {
        Object fact = facts[i];
        System.out.println( "Inserting fact: " + fact );
        ksession.insert( fact );
    }

    ksession.fireAllRules();
}

在Drools中，现在一切都是面向jar的。因此，您需要使用新创建的规则重新构建您的KJar（它可能是一个仅写入内存文件系统的“虚拟KJar”（KieModule）。要查看示例，请查看Drools中的IncrementalComplationTest类[1]。如果搜索Drools代码库，您还可以找到其他测试类和示例。例如，此[2]

    String drlURL ="https://s3.amazonaws.com/somebucket4/rules.drl";
    KieServices kieServices = KieServices.Factory.get();
    KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
    kieFileSystem.write(ResourceFactory.newUrlResource(drlURL));
    KieBuilder kieBuilder = kieServices.newKieBuilder(kieFileSystem);
    kieBuilder.buildAll();
    KieModule kieModule = kieBuilder.getKieModule();
    return kieServices.newKieContainer(kieModule.getReleaseId());
}
