【中文标题】ColdFusion .Net 集成错误：未安装 DotNetExtension

【英文标题】：ColdFusion .Net Integration Error: DotNetExtension not installed

【问题描述】：

我一直在尝试让 .NET 集成服务在我的 ColdFusion 10 环境中正常工作，但尽管卸载/重新安装/重新启动/服务重新启动，但它拒绝在 ColdFusion 中生成代理类。我刚刚将 .NET Framework 升级到 4.6，根据 Adob​​e 的文档，安装新的 .NET Framework 需要卸载/重新安装 CF .NET 服务。 [1]

服务器有几个 ColdFusion 实例正在运行，所以我将 CF .NET 服务安装为独立的，服务本身作为本地系统运行。

我已确保每个实例的 lib 文件夹中的 neo-dotnet.xml 文件包含我安装 .NET 服务的目录，并且我用于测试的 .NET dll 非常简单：

namespace DLLTest

    public class MyClass
    
       public int Add(int x, int y)
        
            return x + y;
        
    

我调用.NET程序集的方式如下：

<cfobject type=".NET" name="testDLL" class="DLLTest.MyClass" assembly="[Absolute_PATH]\DLLTest.dll')">

当 .cfm 页面运行时，它会创建以下堆栈跟踪：

【问题讨论】：

除了 CF 2016 外，我也遇到了同样的问题。我尝试卸载并重新安装 .NET 服务无济于事...

【参考方案1】：

在测试服务器上安装 ColdFusion 2021 企业版后，我收到了同样的错误。之前在 ColdFusion 2016 上运行的代码抛出了这个错误。调试了半天，问题是我2021服务器上的ColdFusion实例没有jnbridge文件夹。它仅位于默认的“cfusion”实例的文件夹中。为了解决这个问题，我做了以下事情：

将“jnbridge”文件夹从 cfusion 复制到我的实例文件夹中 重新启动“ColdFusion 2021 .NET Service”Windows 服务 重新启动“ColdFusion 2021 Application Server INSTANCE_NAME”Windows 服务
