java - 如何从 KIE 工作台获取 kieContainer

Question

我尝试从我通过 KIE Workbench 创建的项目中获取 kieContainer。

    String url = "http://dev.dsack.local:8080/kie-wb/maven2wb/ouTest/projectTest/1.0/projectTest-1.0.jar";
    ReleaseIdImpl releaseId = new ReleaseIdImpl("ouTest", "projectTest", "1.0");
    KieServices kieServices = KieServices.Factory.get();
    kieServices.getResources().newUrlResource(url);
    KieContainer kieContainer = kieServices.newKieContainer(releaseId);

当我用浏览器打开网址时，我可以下载 .jar但在最后一行我收到错误。我不知道我做错了什么。我对maven也不是很熟悉。你能帮我吗？

我想您正在尝试从 Kie 工作台下载 jar，尝试在 maven 中构建 jar 并在项目中使用它。在这种情况下，首先按照以下链接运行此命令， http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html然后在项目 pom 文件中添加 jar 依赖项。您可以使用下面的代码来执行应用程序。在执行过程中，您将需要大量的jar。主要是Kie-ci、kie-internal。

            KieServices kieServices = KieServices.Factory.get(); 

            ReleaseId releaseId = kieServices.newReleaseId("org.test", 
                    "kie-project-simple", "1.0"); 

            KieContainer kContainer = kieServices.newKieContainer(releaseId); 

            kScanner = kieServices.newKieScanner(kContainer); 

            System.out.println("This is a Kie-Ci example. The drl rule is packaged " + 
                    "as a kmodule in a jar and deployed in your maven repo"); 

            // Scan to discover new resources of an existing artifact 
            kScanner.scanNow(); 

            for (int i = 0; i < 100; i++) { 
                // Create a stateless session 
                kSession = kContainer.newKieSession(); 
                kSession.insert("Hello"); 
                kSession.fireAllRules(); 
                try { 
                    Thread.sleep(5000); 
                } catch (InterruptedException e) { 
                    System.out.println("Thread interrupted. Firing of rules will stop."); 
                } 
            }
