利用Webwork的Inputstream和Outputstream进行文件上传
最近在做一个管理系统，里面涉及到了文件上传；在网上找了好多的方法，不过很多都包含有过期的代码，很是郁闷。
努力了几天，终于用利用Webwork的Inputstream和Outputstream实现了文件的上传
下面具体代码：
1.前台jsp代码：
<%--
Created by IntelliJ IDEA.
User: Luckystar_N

--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ include file="/common/inc/tagLib.jsp" %>
<html>
<head><title>添加授课教案管理---Foreign Language Department</title></head>
<body>
<ww:form id="teachingPlan" method="post" namespace="/admin" action="insertTeachingPlan.action"
enctype="multipart/form-data"
validate="true" theme="xhtml">
<table class="formTable" cellpadding="3" cellspacing="1">
<tr class="title">
<td colspan="6"><strong>教案管理</strong></td>
</tr>
<tr>
<ww:file
label="教案上传（1）"
name="teachingPlanPath1"
id="file1"
onchange="javascript:uploadTeachingPlan(1)"
/>
</tr>
<tr>
<td colspan="10">
<li>请将文件压缩后上传，教案格式必须是 *.RAR或 *.ZIP格式，且不能为空！</li>
</td>
</tr>
<tr>
<ww:textarea
tooltip="教案说明要控制在一百字以内！"
label="教案说明（1）"
cols="87"
rows="5"
name="teachingPlan.planInfo1"
labelposition="col5"
value=""/>
</tr>
<tr>
<ww:file
label="教案上传（2）"
name="teachingPlanPath2"
value=""/>
</tr>
<tr>
<td colspan="10">
<li>请将文件压缩后上传，教案格式必须是 **.RAR或 **.ZIP格式，且不能为空！</li>
</td>
</tr>
<tr>
<ww:textarea
tooltip="教案说明要控制在一百字以内！"
label="教案说明（2）"
cols="87"
rows="5"
name="teachingPlan.planInfo2"
labelposition="col5"
value=""/>
</tr>
<tr>
<ww:submit value="添加" labelposition="col6"/>
</tr>
</table>
<ww:actionerror/>
<ww:fielderror/>
<ww:actionmessage/> </ww:form>
</body>
</html>
2.action代码：
public class TeachingPlanAction extends BaseTeachingPlanAction {
public void upFile(File file, String name, String type) throws Exception {
super.execute();
if (file != null) {
FileOutputStream outputStream1 = new FileOutputStream("d:/" + name);
FileOutputStream outputStream2 = new FileOutputStream("d:/" + name);
FileInputStream inputStream = new FileInputStream(file);
byte[] buffer = new byte[1024];
int len;
while ((len = inputStream.read(buffer)) > 0) {
outputStream1.write(buffer, 0, len);
outputStream2.write(buffer, 0, len);
}
inputStream.close();
outputStream1.close();
outputStream2.close();
} else {
}
}
public String insertTeachingPlan() throws Exception {
super.execute();
upFile(teachingPlanPath1, teachingPlanPath1FileName, teachingPlanPath1ContentType);
upFile(teachingPlanPath2, teachingPlanPath2FileName, teachingPlanPath2ContentType);
String path1 = "";
String path2 = "";
if (teachingPlanPath1 != null) {
path1 = teachingPlanPath1.getParent() + teachingPlanPath1FileName;
}
if (teachingPlanPath2 != null) {
path2 = teachingPlanPath2.getParent() + teachingPlanPath2FileName;
}
teachingPlan.setTeachingPlanPath1(path1);
teachingPlan.setTeachingPlanPath2(path2);
this.teachingPlan.userId = teachingPlan.teachingPlanId;
this.teachingPlanDAO.insertTeachingPlan(teachingPlan);
addActionMessage("添加成功");
return SUCCESS;
}
3.TeachingPlan-xwork.xml配置文件
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.1.1//EN" "http://www.opensymphony.com/xwork/xwork-1.1.1.dtd">
<xwork>
<include file="com/common/Base-xwork.xml"/>
<package name="teachingPlan" extends="JpkAdminHomeWork" namespace="/admin">
<action name="insertTeachingPlan" class="com.modules.teachingPlan.action.TeachingPlanAction"
method="insertTeachingPlan">
<external-ref name="teachingPlanDAO">teachingPlanDAOProxy</external-ref>
<interceptor-ref name="validationWorkflowStack"/>
<result name="success" type="dispatcher">
<param name="location">/admin/addTeachingPlan.jsp</param>
</result>
<result name="input" type="dispatcher">
<param name="location">/admin/addTeachingPlan.jsp</param>
</result>
</action>
</package>
</xwork>4.ibatis中SQL语句：
<insert id="insertTeachingPlan" parameterClass="teachingPlan">
<![CDATA[
INSERT INTO teachingplan
(teachingPlanId,teachingName,lessonName,teachingPlanPath1,planInfo1,teachingPlanPath2,planInfo2,userId)
VALUES
(#teachingPlanId#,#teachingName#,#lessonName#,#teachingPlanPath1#,#planInfo1#,#teachingPlanPath2#,#planInfo2#,#userId#)
]]>
<selectKey resultClass="int" keyProperty="teachingPlanId">
SELECT LAST_INSERT_ID();
</selectKey>
</insert>
到此时就可以实现文件上传了.补充一句在这里我要上传两个文件
