注: 开发环境搭建请参照 

      上传的模板请参照 

1.  下载的jsp文件内容

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
      	
        
    
    	
         		
      ${file.type}----
      ${file.name}    		
      -----
      下载    		
      
    	
     	
    
	导入模板下载	
-------------------------------------------------------------------------------
	
    
	
    	 
    
    	
         		
      ${file.type}----
      ${file.name}    		
      -----    		
      下载    		
      
    	
         	
     file----
     test_fail.txt    		
     -----    		
     下载    	
     
    		
          	
     
	
    
			

2.controller 文件处理内容

package com.study.controller;import java.io.File;import java.io.FileInputStream;import java.io.OutputStream;import java.util.ArrayList;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.study.pojo.FileProperty;@Controllerpublic class downloadController {		@Value("#{settings.webServer}")	private String webPath;		//获取目录下所有文件名称	@RequestMapping("listFile")	public String listFile(Model model, HttpServletRequest request, HttpServletResponse response){				List
    
      listFile = new ArrayList<>();		String path = request.getServletContext().getRealPath("/")+"uploadFiles";				File dir = new File(path);				if(!dir.exists()){			return "fail";		}		File[] file = dir.listFiles();		for(int i=0; i
    

3. 简单的FileProperty.java文件

package com.study.pojo;public class FileProperty {	private String name;	private String type;	private String path;		public String getName() {		return name;	}	public void setName(String name) {		this.name = name;	}	public String getType() {		return type;	}	public void setType(String type) {		this.type = type;	}	public String getPath() {		return path;	}	public void setPath(String path) {		this.path = path;	}	}
