<struts-config> <form-beans> <form-bean name="uploadForm" type="org.lxh.struts.form.UploadForm" /> </form-beans> <action-mappings> <action attribute="uploadForm" input="/upload.jsp" name="uploadForm" path="/upload" scope="request" type="org.lxh.struts.action.UploadAction" /> </action-mappings> </struts-config>
这样就可以很方便的完成文件上传操作。
