[align=left][/align][size=medium][/size][color=green]JAVA------Sturts图片上传
第一步：建立一个图片FileUpload 类：{其他的什么导入Sturts框架我就在这里不写啦}
代码演示如下{----}
public class FileUpload {
public void upload(String path,InputStream is){
try {
OutputStream os = new FileOutputStream(path);
byte[] buffer = new byte[1028*8];
int len;
try {
while((len=is.read(buffer))!=-1){
os.write(buffer, 0, len);
}
os.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
**********************************************************************************************
第二步：创建一个实体类
private int u_id;
private String u_name;
private String u_pass;
private String picture;
然后把上面几个属性get/set
***********************************************************************************************
第三步：创建一个Action
public ActionForward add(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DynaActionForm userForm = (DynaActionForm) form;// TODO Auto-generated method stub
User user = (User) userForm.get("user");
String fileName = this.upload(userForm);
user.setPicture(fileName);
if(!ubiz.addUser(user)){
return mapping.findForward("error");
}
return this.list(mapping, userForm, request, response);
<!-- 功能说明： 调用FileUpload方法-->
public String upload(DynaActionForm userForm){
FileUpload up = new FileUpload();
FormFile formFile = (FormFile) userForm.get("formFile");
String fileName = formFile.getFileName();
String path = servlet.getServletContext().getRealPath("/")+"upload/"+fileName;
InputStream is = null;
try {
is = formFile.getInputStream();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
up.upload(path, is);
formFile.destroy();
return fileName;
}
***********************************************************************************************
第四步：配置Sturts{特别要注意}
<form-beans >
<form-bean name="userForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="user" type="org.svse.entity.User"></form-property>
<form-property name="hidden" type="java.lang.String"></form-property>
<form-property name="formFile" type="org.apache.struts.upload.FormFile"></form-property>
</form-bean>
第五步：使用Html标签 <html:file property="formFile"></html:file> [/color]
