tomcat - "java.lang.RuntimeException: Cannot find KieModule"在使用 Tomcat 设置 Drool 中

Question

我们已经使用 Tomcat 8.0 设置和部署了 Drool 7.15 应用程序。但是，问题是当我们尝试部署规则时出现以下异常。 java.lang.RuntimeException:找不到 KieModule:com.tisl.mpl.ruleengine:rrt-kjar:1.0.0

修复这个问题的方法是什么？同样的 jar 在 Wildfly(jBOSS) 中运行良好

Answer 1

您遇到的错误有多种可能的解释。

1) 类路径上缺少 kie-ci 库 - 要解决此问题，您需要将其声明为 Maven 依赖项(或以任何其他方式将其与您的应用程序捆绑在一起)

2) 您在 ReleaseId 中输入错误，带有以下 GAV 的 KJAR 确实不存在:com.tisl.mpl.ruleengine:rrt-kjar:1.0.0

3) KJAR 确实存在，但您错误配置了 settings.xml - 即它缺少上传 KJAR 的远程存储库(或代理等)的配置

4) 您的 settings.xml 已正确配置，但它们未存储在默认位置 ~/.m2/settings.xml。如果是这种情况，您需要设置系统属性 kie.maven.settings.custom 并将其配置到 settings.xml 的位置。即./start.sh -Dkie.maven.settings.custom=/opt/kie/settings.xml

我作为 Drools 的支持工程师工作了 6 年，总是是上述情况之一。
