我正在使用 tomahawk (1.1.11) 和 Mojarra (2.1.4) 开发 JSF 应用程序。当我上传小文件 (kb) 时，它工作正常，但是当我上传大约 160Mb 的文件时，它发送一个错误null source。

到目前为止，这是我的代码：

    <h:form id="menuForm" enctype="multipart/form-data">
        <h:outputLabel for="option" value="Acciones disponibles: " />
        <h:selectOneMenu id="option"
                         value="#{uploadFile.option}">
            <f:selectItem itemLabel="Seleccione una opción..." itemValue="null" />
            <f:selectItems value="#{uploadFile.options}" />
            <f:ajax render="@form" execute="@form" />
        </h:selectOneMenu>

        <h:panelGrid id="dataLoad" columns ="3" 
                     rendered="#{uploadFile.option == 'Agregar información (sin validación).' ||
                                 uploadFile.option == 'Cargar información completa (con validación).' || 
                                 uploadFile.option == 'Cargar solo información errónea (con validación).'}">
            <h:outputLabel for="upfile" value="Archivo: " />
            <t:inputFileUpload id="upfile" 
                               value="#{uploadFile.upFile}" />
            <h:panelGroup/>
            <h:panelGroup/>
            <h:commandButton value="Continuar"
                             onclick="return confirmation()"
                             action="#{uploadFile.upload}" />
        </h:panelGrid>

        <h:panelGrid id="dataValidate" columns="3"
                     rendered="#{uploadFile.option == 'Validar información actual.'}">
            <h:commandButton value=" Validar " action="#{uploadFile.validate()}"/>
        </h:panelGrid>

        <h:panelGrid id="listFiles" columns="3"
                     rendered="#{uploadFile.option == 'Visualizar todos los archivos.'}">
            <t:tree2 id="tree" value="#{listFiles.treeRoot}"
                     var="node" varNodeToggler="t" 
                     clientSideToggle="false">
                <f:facet name="folder">
                    <h:panelGroup>
                        <t:graphicImage value="images/folderOpen.png"
                                        rendered="#{t.nodeExpanded}"
                                        border="0" />
                        <t:graphicImage value="images/folderClose.png"
                                        rendered="#{!t.nodeExpanded}"
                                        border="0" />
                        <h:outputText value="#{node.description}"
                                      styleClass="nodeFolder" />
                    </h:panelGroup>
                </f:facet>
                <f:facet name="file">
                    <h:panelGroup>
                        <h:commandLink immediate="true"
                                       action="#{listFiles.download(node.identifier)}">
                            <t:graphicImage value="images/file.png" border="0" />
                            <h:outputText value="#{node.description}" />
                        </h:commandLink>
                    </h:panelGroup>
                </f:facet>
            </t:tree2>
        </h:panelGrid>
    </h:form>

实际上我需要上传比这更大的文件，甚至高达 2 Gb。有什么建议吗？

最后 ！我找到了问题的原因，但我不确定发生了什么，所以我希望有人可以帮助我解决这个问题。

首先，问题出在web.xml文件上。最后我有类似的东西

<filter-mapping>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <servlet-name>/faces/*</servlet-name>
</filter-mapping>

所以我从 web.xml 中删除它，它上传文件没有任何问题！我认为，服务器对此`filter-mapping和servlet-mapping. 我希望有更多经验的人帮助我（以及所有阅读此问题的人）清除这件事。

兔子，你可以从你正在使用的 apache commons fileupload jar 中取出 FileUploadBase 文件

并根据需要设置最大文件和请求大小限制。这是我在搜索任何配置项以自定义超出 apaches File Upload 1.2.1 100mb 限制的限制后克服大小限制而对我施加的限制。

你可以从http://commons.apache.org/proper/commons-fileupload//index.html获取 src

只需修改源文件重新编译并覆盖文件上传 jar 中现有的类文件

确保您获得与您正在使用的文件上传版本完全对应的源 zip，否则您可能会遇到问题
