问题描述

我正在尝试从我的服务器上获取数据源列表(是的，我是服务器所有者……这不是黑客攻击).

I'm trying to get a list of datasources off my server (Yes I am the server owner...this is not a hack).

我想我通过举两个例子混淆了这个问题 - 所以我正在用一个例子和堆栈跟踪来编辑帖子.

I think I confused the issue by giving two examples - so I'm editing the post with ONE example and the stack trace.

代码

// Create Data Source Object
admin = new cfide.adminapi.Administrator();
admin.login("admin","[password]");

dbserv = createobject("java","coldfusion.server.ServiceFactory").getDatasourceService();
dblist = dbserv.getDatasources(); 
writedump(dblist);

错误信息

The error occurred in C:wwwroot[path][file].cfm: line 6
4 : 
5 :     dbserv = createobject("java","coldfusion.server.ServiceFactory").getDatasourceService();
6 :     dblist = dbserv.getDatasources(); 
7 :     writedump(dblist);
8 : </cfscript>

推荐答案

dbserv = createobject("java","coldfusion.server.ServiceFactory").getDatasourceService();
dblist = dbserv.getDatasources(); 
writedump(dblist);

这适用于 ColdFusion.如果您遇到安全凭证异常，那么您需要像管理员一样登录

This works in ColdFusion. If you are getting securitycredential exception then you need to login as admin like

admin = new cfide.adminapi.Administrator();
admin.login("password","admin");

以下代码将不起作用

dbserv2 = createobject("java","coldfusion.server.DataSourceService");
dblist2 = dbserv2.getDatasources();

而且没有找到正确的投掷方法.主要是因为DataSourceService是一个java接口，没有实现这个方法.它由Executive类实现.

And it is rightfully throwing method not found. Mainly because DataSourceService is a java Interface and doesn't have this method implemented. It is implemented by Executive class.

这篇关于ColdFusion - java 对象方法调用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持编程学习网！
