strut.xml 文件配置

 

这是配置下载文件格式 类型

 

<package name="jkjy_1" namespace="/jkjy" extends="phs-default">
		    <action name="jkjyhd_fbAction_*" class="jkjyhd_fbAction" method="{1}">
		        <result name="success">/jkjy/uploadFile/uploadFile_add.jsp</result>
		        <result name="list">/jkjy/uploadFile/uploadFile_list.jsp</result>
		        <result name="delete" type="redirectAction">jkjy/jkjyhd_fbAction_list</result>
		        <result name="download" type="stream">
		            <param name="contentType">application/octet-stream;charset=ISO8859-1</param> 
	                <param name="inputName">downloadInputStream</param> 
	                <param name="contentDisposition">attachment;filename="${downloadFilename}"</param> 
	                <param name="bufferSize">4096</param> 
		        </result>
		    </action>

 

下载文件名乱码关键

 

/**
	 * 下载文件
	 * @return String
	 */
	public String download() {
		
		this.jkjyhd_fb = this.jkjyhd_fbService.get(this.jkjyhd_fb.getId());
		try {
			this.downloadInputStream = 
				this.jkjyhd_fbService.downloadFile(this.jkjyhd_fb.getType(), 
					this.jkjyhd_fb.getId());
			this.downloadFilename = 
			new String(this.jkjyhd_fb.getFilename().getBytes(),"iso-8859-1");
		}
		catch (Exception e) {
			e.printStackTrace();
			this.error("文件已经被册除!");
		}
		return "download";
	}

<action name="jhsy_hjcxAction_*" class="jhsy_hjcxAction"
		            method="{1}">
		        <result name="list">/jhsy/jhsy_hjcx_list.jsp</result>
		       	<result name="export_excel" type="stream">
				    <param name="contentType">
					    application/vnd.ms-excel
	        	    </param>
				    <param name="inputName">inputStream</param>
				    <param name="contentDisposition">
					    filename="Report_jhsy_hjcx.xls" 
                    </param>
				    <param name="bufferSize">1024</param>
			    </result>
		    </action>
