drools-7.23.0.Final KieContainerImpl KieBaseException

在运行我的应用程序时，我收到一个错误：找不到默认的异常！从KieContainerImpl打来的

我在drools-7.23.0.Final的源代码中找不到KieContainerImpl

我已经搜索了源代码org.kie.api.KieBase和drools.compiler.builder.imp，但找不到KieContainerImpl

try
    {
        kContainer = ks.newKieContainer();
        System.out.println("\ninitialized KieContainer:\t" + kContainer);

        // Verify that kContainer was properly loaded
        Results results = kContainer.verify();

        ...

        /*
         * A KieBase represents a compiled version of a set of assets.
         */
        kBase = kContainer.getKieBase();
        System.out.println("\ninitialized kBase:\n" + kBase);
    }
    catch (NoClassDefFoundError e)
    {
       e.printStackTrace();
    }
    catch (Exception ex)
    {
        System.out.println("Exception!");
        ex.printStackTrace();
    }

我希望verify函数能够工作。结果如下：

    initialized KieContainer:   org.drools.compiler.kie.builder.impl.KieContainerImpl@767e20cf
Exception!

调用

kContainer.getKieBase（）时

不指定任何参数，Drools希望在

kmodule.xml

中找到标记为默认值的

KieBase

看看我的答案

希望有帮助
