springMVC前后端全套的视频上传源码（入门就能看懂）

前端上传样式：

	<#--    -->
	
	
	<#include "/common/global_css.ftl">
	
	
	


	

		

			
			
			

					

		            	
*视频名称：
		      			

		      				
		            	
		            	

	    					

	    				
		            
		            

		            	
*视频路径保利威vid：
		      			

		      				
		            	
		            	

	    					(无需输入)

	    				
		            
		            

		            	
*视频上传：
		      			

							
		      				
		            	
		            
	            

    				

    					
    					
    				
  				
	  		
		
	
	
	
	
	
	
	
	
	

后端代码：

package com.nuocai.modules.uploadfile.controller;

import java.io.File;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

import com.nuocai.core.common.utils.upload.FileUploadConstants;
import com.nuocai.core.mybase.Constants;

@Controller
@RequestMapping("/uploadfile")
public class UploadController {
	//获取到真是路径
	private static String getSavePath(String proVal) {

		if (proVal != null && proVal.equals("")) {
			proVal = "";
		}
		String saveFilePath = FileUploadConstants.getPropValue(proVal);
		if (saveFilePath == null || saveFilePath.equals("")) {
			return null;
		}
		if (!saveFilePath.endsWith("/"))
			saveFilePath += "/";
		// 生成文件保存路径
		File aSaveFile = new File(saveFilePath);
		if (!aSaveFile.isDirectory())
			aSaveFile.mkdirs();
		return saveFilePath;
	}
	/**
	 * UUID命名
	 * 
	 */
	public static String reFileNameByUUID(String filePath, String fileName) {
		String uFileName = UUID.randomUUID().toString();
		uFileName = uFileName.substring(0, 8) + uFileName.substring(9, 13) + uFileName.substring(14, 18) + uFileName.substring(19, 23) + uFileName.substring(24);
		int p = fileName.lastIndexOf(".");
		fileName = uFileName + fileName.substring(p, fileName.length());
		File file = new File(filePath + fileName);
		if (file.exists()) {
			fileName = reFileNameByUUID(filePath, fileName);
		}
		return fileName;
	}
	//**********************uploadMp4***************
	@SuppressWarnings("unused")
	@ResponseBody
	@RequestMapping(value = { "/uploadMp4" }, method = RequestMethod.POST)
	public String uploadMp4(HttpServletRequest request, @RequestParam(value = "mp4", required = false) MultipartFile file) throws Exception {
		String savePath = getSavePath("FILE_PATH_Mp4");
		String path = savePath;// 文件路径
		if (file != null) {// 判断上传的文件是否为空
			String type = null;// 文件类型
			String fileName = file.getOriginalFilename();// 文件原名称
			fileName = reFileNameByUUID(savePath, fileName);
			// 判断文件类型
			type = fileName.indexOf(".") != -1 ? fileName.substring(fileName.lastIndexOf(".") + 1, fileName.length()) : null;
			if (type != null) {// 判断文件类型是否为空
				if ("mp4".equals(type)) {
					// 项目在容器中实际发布运行的根路径
					String realPath = request.getSession().getServletContext().getRealPath("/");
					// 自定义的文件名称
					String trueFileName = String.valueOf(System.currentTimeMillis()) + "." + type;
					// 设置存放图片文件的路径
					path = savePath + fileName;
					System.out.println("存放视频文件的路径:" + savePath);
					// 转存文件到指定的路径
					file.transferTo(new File(path));
					return Constants.SAVE_FILE_MP4 + fileName;
				}
			} else {
				return "false";
			}
		} else {
			return "false";
		}
		return "false";	
	}
}

后端所需要的工具类：

package com.nuocai.core.common.utils.upload;
import java.io.InputStream;
import java.util.Properties;

public class FileUploadConstants {
	public static String EXCELPATH_USER = "";
	
	private static Properties prop=null;
	
	static{
		String path="/config/fileUploadSavePath_windows.properties";
		if(isLinux()){
			path="/config/fileUploadSavePath_linux.properties";
		}
		InputStream in=FileUploadConstants.class.getResourceAsStream(path);
		if(in!=null){
			prop=new Properties();
			try {
				prop.load(in);
				EXCELPATH_USER=prop.getProperty("EXCELPATH_USER");
			} catch (Exception e) {
				throw new RuntimeException(e);
			}
		}
	}
	
	public static String getPropValue(String key){
		String path="/config/fileupload/fileUploadSavePath_windows.properties";
		String val = null;
		if(isLinux()){
			path="/config/fileupload/fileUploadSavePath_linux.properties";
		}
		InputStream in=FileUploadConstants.class.getResourceAsStream(path);
		if(in!=null){
			prop=new Properties();
			try {
				prop.load(in);
				val = prop.getProperty(key);
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
		return val;
	}
	
	public  static boolean isLinux(){
		String osType = System.getProperties().getProperty("os.name").toLowerCase();
		if(osType.startsWith("windows")){
			return false;
		}
		else{
			return true;
		}
	}
}




package com.nuocai.core.mybase;

import com.nuocai.core.common.utils.upload.FileUploadConstants;
import com.nuocai.core.myutil.PropertiesLoader;


/**
 * 全局常量
 * 
 * @author zj
 * 
 */
public abstract class Constants {

	/**
     * 文件存储路径
     */
    public static final String SAVE_FILE_JS="http://static.gswldx.com/js/";
    public static final String SAVE_FILE_CSS="http://static.gswldx.com/css/";
    public static final String SAVE_FILE_IMAGE="http://static.gswldx.com/image/";
    public static final String SAVE_FILE_MP4="http://static.gswldx.com/Mp4/";
    public static final String SAVE_FILE_EXCEL="http://static.gswldx.com/upload/excel/";
    public static final String SAVE_FILE_FILES="http://static.gswldx.com/file/";
}

最好就是Nginx动静分离配置：

server {
	listen       80;
	server_name  static.gswldx.com;
	access_log  static.yijian119.com.access.log;
	location / {		
		#location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css)$ {
        	#        valid_referers *.wafutech.com;
                #	if ($invalid_referer) {
                #        	return 403;
                #	}
        	#}

		root   C:/web/project/js_css_static/;
		#index  index.html index.htm;
	}

}

最后需要注意的时，当文件视频过于大的时候，此时就需要去配置文件里面修改MultipartFile的文件限制大小，完毕，小白直接粘贴也可以看懂，加油！
