我是流口水的新手 . 我正在使用kieFileSystem.write上传DRL文件，首先我试图从我的src / main / resources位置加载它，它运行正常 . 但我的要求是从绝对位置加载DRL文件，如“C：\ properties \ dev \ conf \ AccountRules.drl”，即在我的项目的一边，它不工作，它根本没有执行任何规则，我的代码片段如下面所述：

主文件是：

public static void main（String [] args）{

String[] rules = { "AccountRules.drl" };
    Object[] facts = { new AccountDetails("800222222", true) };
    System.out.println(facts[0]);
    try {
    runRules(rules, facts);
    } catch (Exception e) {
        e.printStackTrace();
    }
    System.out.println(facts[0]);
}

//规则方法：

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

KieServices kieServices = KieServices.Factory.get();
    KieResources kieResources = kieServices.getResources();
    KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
    KieRepository kieRepository = kieServices.getRepository();

    for (String ruleFile : rules) {
        Resource resource = kieResources.newFileSystemResource(new File(HOME_LOCATION +  File.separator , ruleFile)).setResourceType(ResourceType.DRL);
        System.out.println(HOME_DIR +  File.separator + ruleFile);
        // path has to start with src/main/resources
        // append it with the package from the rule
        kieFileSystem.write(HOME_DIR +  File.separator + ruleFile,resource);
    }

    KieBuilder kb = kieServices.newKieBuilder(kieFileSystem);

    kb.buildAll();

    if (kb.getResults().hasMessages(Level.ERROR)) {
        throw new RuntimeException("Build Errors:\n" + kb.getResults().toString());
    }

    KieContainer kContainer = kieServices.newKieContainer(kieRepository.getDefaultReleaseId());

    KieSession kSession = kContainer.newKieSession();

    for (Object fact : facts) {
        kSession.insert(fact);
    }

    kSession.fireAllRules();
}

DRL文件：

import com.test.AccountDetails;

方言“mvel”

/ * *此规则检查它是否属于组1 * /规则"Phone Number starts with"当$ p：AccountDetails（phNo.startsWith（"800"）|| phNo.startsWith（"866"）|| phNo.startsWith（"1800"）|| phNo.startsWith（ "1866"））
然后是System.out.println（"in Phone Number starts with"）; $ p.status = false;结束

规则"Phone Number contains pattern"当$ p：AccountDetails（phNo.contains（"111111"）|| phNo.contains（"222222"）|| phNo.contains（"333333"）|| phNo.contains（"444444"）|| phNo.contains（"555555"）|| phNo . 包含（"666666"）|| phNo.contains（"777777"）|| phNo.contains（"888888"）|| phNo.contains（"999999"）|| phNo.contains（"000000"））
然后是System.out.println（"in Phone Number contains pattern"）; $ p.status = false;
结束

AccountDetails.java：

包com.test;

public class AccountDetails {private String phNo;

private boolean status;

public AccountDetails(String phNo,boolean status) {
    this.phNo = phNo;
    this.status = status;
}

public String getPhNo() {
    return phNo;
}


public void setPhNo(String phNo) {
    this.phNo = phNo;
}


public boolean getStatus() {
    return this.status;
}

public void setStatus(boolean status) {
    this.status = status;
}

@Override
public String toString() {
    return "PhoneNumberDetails [phNo=" + phNo + ", status=" + status + "]";
}

}

任何建议将不胜感激 .
