jsf - 文件上傳不適用於PrimeFaces 4.0 / JSF 2.2.x中的AJAX - javax.servlet.ServletException:請求內容類型不是multipart / form-data




3 Answers

我遇到過同樣的問題。 它似乎與<p:commandButton><p:fileUpload>組件更相關,因為它與<h:commandButton> (即使使用ajax)。

你可以嘗試:

<h:commandButton id="btnSubmit" actionListener="#{testManagedBean.insert}" value="Save">
    <f:ajax execute="@all" render="@form"/>
</h:commandButton> 

我無法告訴你為什麼或如何運作,但它解決了我的問題。 當然,缺點是,你必須自己做造型,至少在Primefaces人員解決這個問題之前。

在挖掘了源代碼並進行一些調試後,如果發現實際上有兩個請求(我在<p:wizard/>嘗試過)。 第一個是實際上傳文件的multipart/form-data 。 它觸發Bean中的fileUploadEvent。 我嚮導下一個按鈕被按下另一個帶有enctype application/www-urlencoded表單被提交。 這會導致異常。 結論是,與我在評論中所寫的不同,抑制異常是一種有效的解決方案。 這甚至可以通過不包括更改Primefaces.jar的方式來完成,如果這些人在將來的版本中解決問題,這是很方便的。

所以這是需要做的事情:

  • 創建一個新類com.yourpackage.fileupload.FileUploadRenderer
  • 將以下代碼複製並粘貼到新類中:

  • faces-config.xml的底部添加以下行:

    <render-kit>
        <renderer>
            <component-family>org.primefaces.component</component-family>
            <renderer-type>org.primefaces.component.FileUploadRenderer</renderer-type>
            <renderer-class>com.yourpackage.fileupload.FileUploadRenderer</renderer-class>
        </renderer>
    </render-kit>
    
  • 你準備好了!

我們做了什麼? 我們創建了自己的FileUploadRenderer,它使用isMultiPartRequest()方法檢查contentType是否真的是multipart/form-data 。 只有當它返回true時才執行其餘的代碼。 在任何其他情況下,不會發生任何事情,這意味著不會拋出任何異常。 如果Primefaces修復了這個問題,你只需要從faces-config.xml刪除這些行來使用它們的類。

如果這對您有用,請告訴我!

編輯

此代碼檢查給定的請求是否為multipart / form-data類型。 如果不是執行被停止。 原始的Primefaces代碼無論如何都會繼續。 正如我上面提到的,如果你在Primefaces組件中上傳文件,實際上有兩個請求:

  1. 使用<p:fileUpload/>的Ajax-FileUpload(enctype: multipart/form-data
  2. <p:editRow/><p:wizard/>的Ajax操作(enctype: application/www-form-urlencoded

第一個由渲染器處理,而第二個在原始代碼中導致異常,因為渲染器嘗試處理它不能處理的東西。 通過代碼中所做的更改,只有multipart/form-data表單由呈現器處理,因此不會發生異常。 IMO顯然是Primefaces來源中的一個錯誤。 代碼差異只是方法private boolean isMultiPartRequest(FacesContext context)及其在代碼中的一次出現。 很高興我能幫到你!

重要提示:自2014年10月6日星期一(幾分鐘前) releasedPrimeFaces 5.1 final (社區發布)以來,此主題中討論的問題已得到fixed 。 我嘗試了JSF 2.2.8-02 (或apiimpl )。

因此,如果您碰巧使用該版本( 或更高版本,無需提及 ),您甚至不需要再閱讀此問題了。

我正在運行一個Web應用程序

  • GlassFish 4.0
  • Mojarra 2.2.4
  • PrimeFaces 4.0決賽

除了使用AJAX上傳文件外,其他一切都運行良好。 以下xhtml文件通過PrimeFaces命令按鈕觸發的AJAX請求發送多部分內容。

<html xmlns="http://www.w3.org/1999/xhtml"

            <p:message for="txtCatImage" showSummary="false"/>
            <p:commandButton id="btnSubmit" 
                             actionListener="#{testManagedBean.insert}" 
                             ajax="true" icon="ui-icon-check" value="Save"/>                
        </h:form>
    </h:body>
</html>

測試託管bean:

@ManagedBean
@ViewScoped
public final class TestManagedBean implements Serializable {

    private static final long serialVersionUID = 1L;
    private UploadedFile uploadedFile;

    public TestManagedBean(){}

    public UploadedFile getUploadedFile() {
        return uploadedFile;
    }

    public void setUploadedFile(UploadedFile uploadedFile) {
        this.uploadedFile = uploadedFile;
    }

    public void fileUploadListener(FileUploadEvent event){
        uploadedFile=event.getFile();
    }

    public void insert(){
        if(uploadedFile!=null){
            System.out.println(uploadedFile.getFileName());
        }
        else{
            System.out.println("The file object is null.");
        }
    }
}

從文件瀏覽器上載文件時,它會在其偵聽器中顯示文件名fileUploadListener()

上傳文件後,當按下給定的命令按鈕( ajax="true" )時,它會引發以下異常。

它只能在命令按鈕的ajax屬性設置為false時起作用 - ajax="false"

我已將Tomcat 7.0.35中的Mojarra版本降級為2.1.9。 它與此Mojarra版本以及PrimeFaces 4.0 final(以及PrimeFaces 4.0 RC1)一起工作 - 使用AJAX請求上傳的文件。

我曾嘗試過以下Mojarra版本

  • 2.2.0
  • 2.2.1
  • 2.2.2
  • 2.2.3
  • 2.2.4

在GlassFish 4.0中,但沒有一個成功上傳帶有AJAX請求的文件,這是非常必要的,因為在PrimeFaces DataTable中使用<p:rowEditor/> (以及每行中的圖像)編輯行總是基於AJAX。

無論如何,我想保留GlassFish 4.0 。 我還嘗試在GlassFish 4.0中降級Mojarra 2.1.9,但它無法創建以異常結尾的bundle。 GlassFish 4.0似乎不適用於低於2.2.x的Mojarra。

那麼,造成這種異常的原因是什麼 - PrimeFaces或JSF? 只是困惑。 在這個給定的環境中,是否有任何解決方法可以上傳帶有AJAX請求的文件?

編輯:

web.xml過濾映射:

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

隨著2014年1月8日released的Mojarra 2.2.5版(或apiimpl )問題,該問題仍然存在。

再次嘗試2014年3月4日released的Mojarra 2.2.6版(或apiimpl )。問題依然存在。

仍然無法在released年5月5日released PrimeFaces 5.0最終releasedreleased




雖然這已經很老了並且已經回答了,但我想分享一些東西,以防你錯過它:PrimeFaces 4+現在有一個上下文參數,你可以使用它(在web.xml中)手動選擇應該使用哪個上傳器(原生的) -servlet3或commons)。 您可以使用此方法強制公共上傳器,如下所示:

<context-param>
   <param-name>primefaces.UPLOADER</param-name>
   <param-value>commons</param-value>
</context-param>

(當然,您仍然需要FileUploadFilter,如上所述和指南中所述)。 有關詳細信息,請參閱PrimeFaces用戶指南。




我有同樣的問題,在我的情況下,我在數據表中使用了primefaces文件上傳器,嘗試使用onRowEdit修改現有圖像,最終得到了上面提到的相同錯誤。然後我將primefaces jar更改為5.1版本。現在它的工作正常。
