爲什麼ColdFusion Implicit Setter最終會進行聯網調用？

我在CFC的init（）方法中有一個隱式setter。我觀察過（使用Fusion Reactor，並通過錯誤消息），簡單地調用setActive（false）最終進行聯網。我不知道爲什麼ColdFusion會在使用ColdFusion 9引入的隱式設置器來設置此值時做這麼多工作。爲什麼ColdFusion Implicit Setter最終會進行聯網調用？

我正在運行最新的ColdFusion 9.01並應用了所有修補程序更新。

你知道爲什麼ColdFusion會經歷所有這些麻煩嗎？

謝謝。

/* Constructor 
    @user_id A valid User_ID. If provided, the User will self-populate. 
*/ 
public shared.models.objects.User function init (numeric user_id = -1) { 
    super.init(argumentCollection=arguments); 

    // Prepare structs required for 'adding' methods 
    clearRoles(); 
    setActive(false); // <--- THIS IS THE LINE 

    setUser_ID(user_id); 

    settings = {}; 

    defaultLanguage = new shared.models.objects.Language(); 

    setLanguages([defaultLanguage]); 
    setLanguage(defaultLanguage); 

    if (user_id == -1) { 
     // Construct a 'blank' User 
     // addRole('Contributor'); 
     setRequirePasswordChange(false); 
    } else { 
     // Attempt to populate a user 
     populate(); 
    } 

    return this; 
}

您的CFC是否擴展了可能已明確定義了setActive的另一個組件？ – 2012-02-27 22:26:10

另外，您是否爲您的CFC定義了onMissingMethod函數（或者您可能要擴展的CFC）？ – 2012-02-27 22:28:20

@JakeFeasel不，沒有另一個setActive（）方法，並且沒有onMissingMethod（）。謝謝。 – 2012-02-28 16:19:10

我遇到了同樣的問題。我相信我可以爲此添加一些內容，但最終我認爲這裏有一個CF缺陷，我將嘗試詳細闡述。在堆棧

首先注意跟蹤此：

at coldfusion.runtime.CgiScope.resolve(CgiScope.java:221) 
    at coldfusion.runtime.CgiScope.containsName(CgiScope.java:301) 
    at coldfusion.runtime.CgiScope.search(CgiScope.java:334) 
    at coldfusion.runtime.NeoPageContext.searchScopes(NeoPageContext.java:766) 
    at coldfusion.runtime.NeoPageContext.findAttribute(NeoPageContext.java:638)

當ColdFusion的嘗試解決無作用域的變量，它會通過優先級的範圍順序測試每個範圍工作的方式了。如果它一直到CGI範圍，則CF服務器將嘗試向Web服務器連接器詢問請求標題中的CGI信息。反過來，連接器嘗試從持有TCP連接的連接器句柄讀回瀏覽器。您在這篇文章原始郵件中看到的網絡連接可能是嘗試通過TCP從瀏覽器收集一些CGI屬性的連接器。

如果瀏覽器連接不再處於活動狀態，比如說用戶關閉了瀏覽器，在其他地方點擊了，或者網絡中斷，那麼TCP連接可能是「陳舊的」。在這種情況下，你會看到在日誌堆棧跟蹤這樣與主要信息是「**錯誤錯誤而讀頭」

03/06 13:45:52 error Error while reading header <headername> 
java.net.SocketTimeoutException: Read timed out 
at java.net.SocketInputStream.socketRead0(Native Method) 
... 
at coldfusion.runtime.CgiScope.resolve(CgiScope.java:221) 
at coldfusion.runtime.CgiScope.containsName(CgiScope.java:301) 
at coldfusion.runtime.CgiScope.search(CgiScope.java:334)

的ColdFusion會做一個範圍查找使用代碼時像isdefined（」例如myUnscopedVar'）。如果它一直到CGI，那麼它會向連接器詢問名爲myUnscopedVar的標頭。如果瀏覽器連接消失了，那麼日誌將顯示「錯誤錯誤，而讀頭myUnscopedVar」

，以避免在您將使用isDefined所有地方使用structKeyExists的方式。

更多細節在這些相關的博客條目中找到了：

如果你搜索這條錯誤消息「錯誤埃羅r在讀取標題時「實際上會在搜索結果中獲得大量誤報，因爲ColdFusion的CFSAVECONTENT標記是作爲存儲在WEB-INF中的CF自定義標記實現的，而它具有類似的功能，具有相同的效果isDefined（「anUnscopedVar」）捕獲生成內容的方式。內置的CF異常處理程序在嘗試顯示異常時使用cfsavecontent，因此它會捕獲潛在的應用程序異常，嘗試相當漂亮，但遇到「讀取標題時發生錯誤錯誤」問題，而不是看到原來的應用程序異常，你得到這個頭文件錯誤掩蓋了真正的問題。

    at coldfusion.runtime.CgiScope.containsName(CgiScope.java:301) 
    at coldfusion.runtime.CgiScope.search(CgiScope.java:334) 
      ... 
    at cfsavecontent2ecfm1472308084.runPage(E:\cf9_final\cfusion\wwwroot\WEB-INF\cftags\savecontent.cfm:11) 
      ... 
    at cfexception_en2exml1502993924.runPage(D:\JRun4\servers\cfusion\cfusion.ear\cfusion.war\WEB-INF\exception\exception_en.xml:52)

    at cfApplicationException2ecfm797577125.runPage(D:\JRun4\servers\cfusion\cfusion.ear\cfusion.war\WEB-INF\exception\coldfusion\runtime\ApplicationException.cfm:2)

同樣的結論是，如果瀏覽器連接已斷開，然後你的代碼可以由由於使用上的未範圍變量isDefined意圖或者做一個CGI查詢時，顯示「讀取頭」錯誤名稱。

所以這只是一些相關的背景信息。此問題與此線程中的ORM問題相交。

我發現在ColdFusion 9.01中，有時調用隱式設置器會導致ColdFusion嘗試解析setter方法，就像它是一個屬性一樣，它會查看CGI範圍以嘗試找到它。

我這裏顯示如下實體（部分）：

component persistent="true" table="myTable" output="false" extends="myBaseClass" { 
property name="myProperty" column="myProperty" type="date" ormtype="timestamp";

注意，它擴展myBaseClass，其顯示（部分）在這裏：

component { 
public void function doSomething(){ 
    if (hasProperty('myProperty')) 
     setMyProperty(now()); 
}

在某些情況下，當一個模板要求使用該實體，模板請求似乎在地址欄旋轉時無限期地掛在瀏覽器中。稍後在查看日誌時，我會找到一個相關條目，顯示「閱讀標題時出錯」。

      ... 
      at cfsomecomp2ecfc1707726523$funcRUN.runFunction(X:\MyApp\SomeComp.cfc:131)

此堆棧跟蹤告訴我的ColdFusion試圖解決一個隱含的制定者，並試圖通過要求連接器同名的HTTP請求頭找到它的CGI範圍。

對我來說，試圖通過搜索CGI作用域的Request Header來解析一個隱式getter，就像是一個ColdFusion缺陷。

意見？
