application.cfc 显示数据源消息 "Variable PRIMARYDATASOURCE is undefined" 的问题

Question

当我尝试使用 Application.cfc 中定义的数据源在 index.cfm 中触发简单的 select 查询时，它显示一条错误消息。任何人都可以帮助我正确的代码序列吗？

错误：

Variable PRIMARYDATASOURCE is undefined

Application.cfc

<cfcomponent>

    <!--- Set up the application. --->
    <cfscript>
        this.name = ""; // app name from old cfapplication tag
        this.sessionManagement = "Yes";
        this.loginstorage="session";
        this.setClientCookies = "Yes";
        this.primarydatasource = "diet";
        application.PRIMARYDATASOURCE = "diet";
    </cfscript>

    <cfsetting requesttimeout="100000" />

    <cffunction name="onApplicationStart">
            ....

        <cfquery datasource="#application.PRIMARYDATASOURCE#" name="getCostDetails">
            select * from maimun.adCostDetails ORDER BY ID DESC
        </cfquery>
            ....
    </cffunction>

</cfcomponent>

将行 application.PRIMARYDATASOURCE = "diet"; 移动到 onApplicationStart 函数并删除行 this.primarydatasource = "diet";。完成。

放置在Application.cfc 正文中的代码根本没有按照您认为的方式执行。您只能在应用程序初始化后访问 application 作用域 - onApplicationStart 是该事件的事件。将其视为 Web 应用程序的构造函数。
