struts2 如何接收input name[] 的数组或者集合

HTML5上传需要action接收imput数组:

直接看代码:

<span style="white-space:pre">					</span><div class="btns">';
html += '					<input id="fileImage" type="file" size="30" name="<strong>fileselect[]</strong>" '+multiple+'>';
html += '					<div class="webuploader_pick">选择文件</div>';
html += '					<div class="upload_btn">开始上传</div>';
html += '				</div>';

package com.danlan.action;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.apache.struts2.ServletActionContext;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;

import com.danlan.util.FileUtil;

/**
* 多照片上传
* @author Administrator
*
*/
@Controller("uploadActions")
@Scope("prototype")
@Transactional
public class UploadActions {

// 接收临时文件对象
List<File> fileselect;

private File fileImage;

// 接收原始文件名，页面文本框name值+FileName
private String uploadInf;

public String execute() {

if(fileselect == null )
return "error";

// 拼相对于当前项目部署的路径apache-tomcat-6.0.36\webapps\StrutsDay06
uploadInf = "upload/";
// 根据相对路径找到其完整路径
uploadInf = ServletActionContext
.getServletContext().getRealPath(uploadInf);

System.out.println(uploadInf);
System.out.println(fileselect.size());
for(File some:fileselect){
FileUtil.copy(some, new File(uploadInf));

}
return "success";
}

public void setUploadInf(String uploadInf) {
this.uploadInf = uploadInf;
}

}


struts2.xml就不写了

不管是AJAX还是表单.都可以.

明天再把上传逻辑改为微信JS -SDK 接口上传.
