使用ssh上传文件

1.在upload.jsp页面中,亮黄色的是重点

<div class="pageContent">
<form method="post" enctype="multipart/form-data" action="doAdd" class="pageForm required-validate" onsubmit="return iframeCallback(this, dialogAjaxDone);">
<div class="pageFormContent" layoutH="56">
<p style="width: 980px;">
<label>标题：</label> <input type="text" size="30" name="noticeTitle"/>
</p>
<p style="width: 980px;">
<label>图片或共享文件：</label> <input name="image" type="file" size="15"/>
</p>
<p style="width: 980px;">
<label>内容：</label>
<textarea name="noticeContent" id="editor" class="editor" name="description" rows="25" cols="100">
</textarea>
</p>

</div>
<div class="formBar">
<ul>

<li><div class="buttonActive"><div class="buttonContent"><button type="submit">保存</button></div></div></li>
<li>
<div class="button"><div class="buttonContent"><button type="button" class="close">取消</button></div></div>
</li>
</ul>
</div>
</form>
</div>

2.在struts.xml中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>


<constant name="struts.multipart.maxSize" value="10701096"/>

<constant name="struts.multipart.saveDir " value="d:/tmp" />

<package name="NOTICES" namespace="/" extends="json-default">

<action name="doAdd" class="showNotice" method="addSave">
<result name="success" type="json"/>
<result name="error" type="json"/>



<param name="savePath">/upload</param>
<result name="success" type="json">
<param name="contentType">text/html</param>
</result>

<interceptor-ref name="fileUpload">




</interceptor-ref>

<interceptor-ref name="defaultStack" />
</action>
</package>
</struts>

3.在UploadHelper.java中

package noticeCOMMON;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class UploadHelper extends ActionSupport {

// 封装上传文件域的属性
private File image;
// 封装上传文件类型的属性
private String imageContentType;
// 封装上传文件名的属性
private String imageFileName;
// 接受依赖注入的属性
private String savePath;

public String startUpFile() {
FileOutputStream fos = null;
FileInputStream fis = null;
try {
// 建立文件输出流
System.out.println(getSavePath());
fos = new FileOutputStream(getSavePath() + "\\" + getImageFileName());
// 建立文件上传流
fis = new FileInputStream(getImage());
byte[] buffer = new byte[1024];
int len = 0;
while ((len = fis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
} catch (Exception e) {
System.out.println("文件上传失败");
e.printStackTrace();
} finally {
close(fos, fis);
}
return SUCCESS;
}

/**
* 返回上传文件的保存位置
*
* @return
*/
public String getSavePath() throws Exception{
return ServletActionContext.getServletContext().getRealPath(savePath);
}

public void setSavePath(String savePath) {
this.savePath = savePath;
}

public File getImage() {
return image;
}

public void setImage(File image) {
this.image = image;
}

public String getImageContentType() {
return imageContentType;
}

public void setImageContentType(String imageContentType) {
this.imageContentType = imageContentType;
}

public String getImageFileName() {
return imageFileName;
}

public void setImageFileName(String imageFileName) {
this.imageFileName = imageFileName;
}

private void close(FileOutputStream fos, FileInputStream fis) {
if (fis != null) {
try {
fis.close();
} catch (IOException e) {
System.out.println("FileInputStream关闭失败");
e.printStackTrace();
}
}
if (fos != null) {
try {
fos.close();
} catch (IOException e) {
System.out.println("FileOutputStream关闭失败");
e.printStackTrace();
}
}
}

}

4.在实体类中继承UploadHelper.java

5.在applicationContext.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans

xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<bean id="noticeDAOImpl" class="noticeDAOIMPL.noticeDAOImpl"></bean>
<bean id="showNotice" class="noticeSERVICE.noticeService" scope="prototype">
<property name="notice" ref="noticeDAOImpl"></property>
</bean>
</beans>

6.在noticeService.java类中的addSave方法中

// 添加保存
public String addSave() throws Exception {
Notices m = new Notices();
m.setNoticeTitle(getNoticeTitle());
m.setNoticeContent(getNoticeContent());
String finename=getImageFileName().toLowerCase();
String exsString=finename.substring(finename.lastIndexOf(".")+1);
if (exsString.equals("bpm")||exsString.equals("png")||exsString.equals("gif")||exsString.equals("jpeg")||exsString.equals("jpg")) {
//图片
m.setNoticeImg(getImageFileName());
}else {
m.setNoticeFile(getImageFileName());
m.setNoticeImg("img");
}
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date dt=new Date();
m.setNoticeTime(sdf.format(dt));
dwzResult dr = new dwzResult();
dr.setMessage("操作成功");
int flag = notice.addNotice(dp, m);
if (flag > 0) {
// 图片上传时，调用Common类中的startUpFile（）方法
startUpFile();
//文件上传
dr.setStatusCode("200");
// 使用JSONObject生成json
JSONObject json = JSONObject.fromObject(dr);
// 给了自定义的属性,在前台的DWZ框架中from表单中return iframeCallback(this,
// dialogAjaxDone)
setDwzJsonResult(json.toString());
return SUCCESS;
} else {
dr.setStatusCode("300");
JSONObject json = JSONObject.fromObject(dr);
setDwzJsonResult(json.toString());
return ERROR;
}
}
