我是 Drools 和 Guvnor 的新手。我们已经创建了 DRL 文件并在 Guvnor 中加载，我们构建了包。它产生了一个.pkg文件。我们从 Guvnor 下载此.pkg文件并将其用于我们的不同项目。现在我正在尝试查看.pkg文件中的内容，但我不知道如何打开它。

没有工具（我知道）用于打开 Drools pkg 文件并检查其内容。根据您要实现的目标，可能的解决方案是以编程方式从该 pkg 创建一个 Kiebase（或 kbase）并以编程方式检查其内容。

顺便说一句，您想在该文件中找到什么？

希望能帮助到你，

The following code examines a knowledge base and will write out the names of all the packages that were loaded into it and the names of the rules in those packages. There's probably a bit more info that can be extracted, but I have never found the need. The only thing you won't get is the source code of the rules. But going by your explanation, that is available in Guvnor.

/**
 * Return a string containing the packages used to build the knowledge base.
 */
public static String knowledgeBaseDetails(KieBase kbase) {
    if (kbase == null) {
        return "Knowledge Base is null.";
    } else {
        StringBuilder sb = new StringBuilder(
                "Knowledge base built from the following packages:");
        Collection<KiePackage> packages = kbase
                .getKiePackages();
        for (KiePackage kp : packages) {
            sb.append("\n    Package: [" + kp.getName() + "]");
            for (Rule rule : kp.getRules()) {
                sb.append("\n        Rule: [" + rule.getName() + "]");
            }
        }
        return sb.toString();
    }
}

It's almost the same for Drools 5 and 6. Generally for the earlier versions of Drools, just change Kie to Knowledge.
