Drools无法从InputStream创建MavenProject

时间：2018-01-17 12:15:12

标签： java maven drools drools-kie-server

我有一个Drools决策表实现，可以在我的开发机器上运行，但不能在云中部署到我的VM。现在这表明存在部署问题，但对于我的生活，我无法看到问题所在。

uk.co.example.equi.e​​quiClient的第321行是kbuilder.buildAll（）;

以下是我遇到的错误：

这是代码

    KieServices kieServices = KieServices.Factory.get();

    KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
    Resource resource = kieServices.getResources().newClassPathResource("dtables/applylncc.xlsx");
    // create compiler class instance
    SpreadsheetCompiler sc = new SpreadsheetCompiler();

    kieFileSystem.write(resource);
    KieBuilder kbuilder = kieServices.newKieBuilder(kieFileSystem);

    kbuilder.buildAll();
    KieRepository kieRepository = kieServices.getRepository();
    KieContainer kContainer = kieServices.newKieContainer(kieRepository.getDefaultReleaseId());
    applySession = kContainer.newKieSession();

我也遇到了同样的错误。添加以下依赖关系为我解决了这个问题：     <% content_for :javascript_includes do %> <%= javascript_include_tag "charges.js" %> <% end %> <style> #pageBox { width: 600px; margin: 60px auto; } .header { text-align: center } .content { margin-top: 50px; } </style> </div>
