Question

我们目前正在将我们的应用程序从struts 1迁移到struts 2模块，我们正在使用struts2-strut1插件。

每件事似乎都运行良好，期待文件我们将文件属性值设为NULL。

我们已经检查过所有标签下面的所有标签

JSP code Snippet

<s:form name="uploadForm" namespace="/struts2" action="upload" enctype="multipart/form-data" method="post">
    <s:file name="doc" cssClass="genTextValues"/>
    <s:submit/>
</s:form>

Java Action表单

public class UploadForm extends ActionForm {             
        private FormFile doc;
        public FormFile getDoc() {
            return doc;
        }
        // its not setting gives null in action form
        public void setDoc(FormFile doc) {
            this.doc = doc;
        }
    }

Struts.xml映射

<interceptor name="uploadForm" class="com.opensymphony.xwork2.interceptor.ScopedModelDrivenInterceptor">
        <param name="scope">request</param>
        <param name="className">com.form.UploadForm</param>
        <param name="name">uploadForm</param>
    </interceptor>
    <interceptor-stack name="iUploadForm">
        <interceptor-ref name="staticParams" />
        <interceptor-ref name="uploadForm" />
        <interceptor-ref name="modelDriven" />
        <interceptor-ref name="basicStack" />    
    </interceptor-stack>
    <action name="uploadDoc" class="org.apache.struts2.s1.Struts1Action">
        <param name="className">com.test.action.UploadAction</param>
    <interceptor-ref name="iUploadForm"/>
        <result name="Success" type="tiles">Success</result>
    </action>

我们已经添加了必需的jar，见下文：

commons-fileupload.jar
struts.jar
struts2-struts1-plugin.jar
struts2-core.jar (2.16)
commons-io2.2.jar

其他必需的罐子

Answer 1

fileUpload中没有interceptor-stack拦截器。

 <interceptor-stack name="iUploadForm">
        <interceptor-ref name="staticParams" />
        <interceptor-ref name="fileUpload"/>
        <interceptor-ref name="uploadForm" />
        <interceptor-ref name="modelDriven" />
        <interceptor-ref name="basicStack" />    
 </interceptor-stack>

文件上传在Struts2-Struts1插件中不起作用，其设置为NULL
