struts2实现多文件上传的示例代码

时间:2022-06-25 14:22:21 编辑:袖梨 来源:一聚教程网

开发环境JDK1.8 eclipse struts2-2.3.31

1.创建web项目

2.导入struts2核心jar包

3.更改web.xml配置文件(只要配置好struts2的Filter就好)

4.创建src/struts.xml文件

代码如下 复制代码

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.a**pa*che.org/dtds/struts-2.0.dtd">

WEB-INF/images

/success.jsp

/error.jsp

image/bmp,image/png,image/gif,image/jpeg

1025956

5.创建src/com.ifan.action.FileUpload.Java

代码如下 复制代码

packagecom.ifan.action;

importjava.io.File;

importorg.apache.commons.io.FileUtils;

importorg.apache.struts2.ServletActionContext;

importcom.opensymphony.xwork2.ActionContext;

importcom.opensymphony.xwork2.ActionSupport;

publicclassFileUploadextendsActionSupport{

privateFile[] image;//上传的文件

privateString[] imageFileName;//文件名称

privateString[] imageContentType;//文件类型

publicString execute()throwsException {

ServletActionContext.getRequest().setCharacterEncoding("UTF-8");

String realpath = ServletActionContext.getServletContext().getRealPath("/images");

System.out.println(realpath);

if(image !=null) {

File savedir=newFile(realpath);

if(!savedir.getParentFile().exists())

savedir.getParentFile().mkdirs();

for(inti=0;i

File savefile =newFile(savedir, imageFileName[i]);

FileUtils.copyFile(image[i], savefile);

}

ActionContext.getContext().put("message","文件上传成功");

}

return"success";

}

publicFile[] getImage() {

returnimage;

}

publicvoidsetImage(File[] image) {

this.image = image;

}

publicString[] getImageContentType() {

returnimageContentType;

}

publicvoidsetImageContentType(String[] imageContentType) {

this.imageContentType = imageContentType;

}

publicString[] getImageFileName() {

returnimageFileName;

}

publicvoidsetImageFileName(String[] imageFileName) {

this.imageFileName = imageFileName;

}

}

6.创建WebContent/index.jsp ,作为上传文件的页面

代码如下 复制代码

String path = request.getContextPath();

String basePath = request.getScheme() +"://"+ request.getServerName() +":"+ request.getServerPort()

+ path +"/";

%>

My JSP'hello.jsp'starting page

7.创建WebContent/success.jsp 作为文件上传成功跳转的页面,创建WebContent/error.jsp 作为文件上传失败的页面 , 创建WebContent/images文件夹,作为上传文件的存储位置
