java - ColdFusion - java对象方法调用

Question

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

我认为我通过给出两个示例混淆了这个问题 - 因此我正在使用一个示例和堆栈跟踪来编辑这篇文章。

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);

错误消息

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>

堆栈跟踪:

Answer 1

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，那么您需要以管理员身份登录

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();

并且它正确地抛出了未找到的方法。主要是因为DataSourceService是一个java接口(interface)，没有实现这个方法。它是由Executive类实现的。
