Question

我想将drools workbench 6.4.0.Final与我自己的应用程序集成。

以下是主要课程：

package com.example;
import com.idss.poc.CouponFact;
import com.idss.poc.Result;
import org.codehaus.plexus.util.FileUtils;
import org.drools.compiler.kie.builder.impl.KieServicesImpl;
import org.drools.compiler.kproject.ReleaseIdImpl;
import org.drools.core.io.impl.UrlResource;
import org.kie.api.KieServices;
import org.kie.api.builder.KieModule;
import org.kie.api.builder.KieRepository;
import org.kie.api.builder.KieScanner;
import org.kie.api.builder.ReleaseId;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.StatelessKieSession;
import org.kie.scanner.KieScannerFactoryServiceImpl;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;


public class FunctionExample {
    public static void main(String[] args) {
        KieServices ks = KieServices.Factory.get();
        ReleaseId releaseId = ks.newReleaseId( "com.test", "poc", "LATEST" );

        KieContainer kContainer = ks.newKieContainer(releaseId);
        KieScanner kieScanner = ks.newKieScanner(kContainer);

        kieScanner.start( 10000L );

        Scanner scanner = new Scanner(System.in);

        while (true) {
            kieScanner.scanNow();
            String line = scanner.nextLine();
            runRule(kContainer);
        }
    }

    private static void runRule(KieContainer kieKontainer) {
        StatelessKieSession kSession =kieKontainer.newStatelessKieSession("ks");
        Result result = new Result();
        List<String> list = new ArrayList<String>();
        result.setRules(list);

        kSession.setGlobal("result", result);

        CouponFact cf = new CouponFact();
        cf.setPhoneCount(2);
        cf.setUserCount(2);
        cf.setDeviceCount(2);
        cf.setIp10mCount(10);
        cf.setIpDayCount(10);
        kSession.execute(cf);

        System.out.println(result.getScore() + "," + result.getRules());
    }
}

以下是我自己的应用程序使用的settings.xml。

<?xml version="1.0" encoding="UTF-8"?>

      </repositories>
    </profile>
  </profiles>
  <activeProfiles>
   <activeProfile>guvnor-m2-repo</activeProfile>
  </activeProfiles>
</settings>

当我在工作台中更新我的drools规则，并升级我的repo的版本，但我的应用程序没有自动获得我的repo的最新版本。我得到这样的日志：

任何人都可以帮我搞清楚吗？谢谢！

Answer 1

如果您在应用程序的版本号字段中使用LATEST，KieScanner会尝试将本地存储库中可用jar的版本号与kie-workbench中可用的jar版本号相匹配。如果两个版本都相同，则它不会从远程存储库获取jar并使用本地存储库中的jar。每次构建和部署时，都要增加更改的版本号，以便在应用程序端反映出来。

如果每次部署时增加版本号对您来说太多了，我建议您在版本号中使用-SNAPSHOT。即使本地存储库中有相同的版本，也始终从远程存储库获取快照版本。 <version>-SNAPSHOT应仅用于开发目的。

Answer 2

我假设你把＃34; LATEST＆＃34;以获取KJAR的最新快照版本。

如果是这种情况，我相信您需要将快照更新策略设置为大于＆＃34;每天＆＃34;默认。此外，您的maven设置文件似乎有错误，因为items.RemoveAll(x => x.arret.Equals("value") && x.ligneSensName.Equals("ligneValue"));标记未正确嵌套。我建议你尝试这样的事情：

updatePolicy

参考：https://maven.apache.org/settings.html#Repositories

Answer 3

感谢 @taralabs 和 @Naved Alam ，您的回答只是帮助我。我读了drools文档，它告诉我：

如果使用SNAPSHOT，版本范围，LATEST或RELEASE设置，KieScanner将仅对已部署的jar进行拾取更改。固定版本不会在运行时自动更新。

所以，我修改了我的工作台项目，并将版本号设置为 2.0.0-SNAPSHOT ，并更改了我的代码

ReleaseId releaseId = ks.newReleaseId( "com.test", "poc", "LATEST" );

到

ReleaseId releaseId = ks.newReleaseId( "com.test", "poc", "2.0.0-SNAPSHOT" );

到目前为止，它再次无法正常工作。该程序显示如下日志：

11:50:24.158 [Timer-0] DEBUG org.kie.scanner.embedder.MavenEmbedderUtils - Not in OSGi: using plexus based maven parser
11:50:24.212 [Timer-0] DEBUG org.eclipse.aether.internal.impl.DefaultLocalRepositoryProvider - Using manager EnhancedLocalRepositoryManager with priority 10.0 for /Users/pinter/Desktop/RiskGuard/~/.m2/repository

正如我们所见，中央存储库 https://repo.maven.apache.org/maven2 已被我的自定义远程存储库 http://10.10.10.57:8080/kie-wb/maven2 覆盖。

我尝试更改我的settings.xml

<mirrors>
    <mirror>
      <id>mymirror</id>
      <url>http://10.10.10.57:8080/kie-wb/maven2</url>
      <mirrorOf>*</mirrorOf>
      <layout>default</layout>
    </mirror>
</mirrors>

到

<mirrors>
    <mirror>
      <id>mymirror</id>
      <url>http://10.10.10.57:8080/kie-wb/maven2</url>
      <mirrorOf>guvnor-m2-repo</mirrorOf>
      <layout>default</layout>
    </mirror>
</mirrors>

它工作正常!!!

KieScanner无法自动获取最新版本！
