如何在 Coldfusion 中使用 java 文件

2022-01-09 00:00:00 import coldfusion java coldfusion-8

我需要将 java 文件导入 Coldfusion 8 页面，例如:

I need to import a java file into a coldfusion 8 page e.g. :

public class Hello 
{ 
    public String testJava() 
    { 
    return "Hello Java!!"; 
    } 
}

在 Coldfusion 中，我有以下代码:

In Coldfusion I have the following code:

<cfscript>
   helloWorld = CreateObject("java","Hello");
   helloTest = helloWorld.testJava();
</cfscript>

然后我收到错误

对象实例化异常.找不到类:你好

Object Instantiation Exception. Class not found: Hello

在我的 Coldfusion 服务器中，Java 虚拟机路径设置为C:/ColdFusion8/runtime/jre"，所以这是我放置 java 文件的位置，对吗?我应该在里面放一个 .java、.class 还是 .jar?

In my Coldfusion server Java Virtual Machine Path is set to 'C:/ColdFusion8/runtime/jre', So this is where I have put my java file, is this correct? Should I put a .java, .class or .jar there?

文件名需要和类名一致吗?

Does the file name need to be consistent with class name?

有没有人可以尝试类似的工作示例代码?

Does anyone have working sample code for something similar I can try?

推荐答案

您需要将文件放在 ColdFusion JVM 的类路径中，而不是其 JRE 目录中.

You need to put the files on the ColdFusion JVM's classpath, not in its JRE dir.

一般来说，如果你有一个jar文件，把它放在实例的WEB-INF/lib目录，如果它只是一个类，把它放在WEB-INF/classes 目录，例如:对我来说后者是 C:appsadobeColdFusion11fullcfusionwwwrootWEB-INFclasses，其中 C:appsadobeColdFusion11full 是我安装 CF 的地方，cfusion 是实例的名称.

As a rule, if you have a jar file, put it in the instances's WEB-INF/lib dir, if it's just a class, put it in the WEB-INF/classes dir, eg: for me the latter would be C:appsadobeColdFusion11fullcfusionwwwrootWEB-INFclasses, where C:appsadobeColdFusion11full is where I installed CF, and cfusion is the name of the instance.
