Springboot ：

1、编写application.properties配置文件

#thymeleaf
spring.thymeleaf.cache=false
spring.thymeleaf.prefix=classpath:/templates/       // 配置视图解析器前缀路径
spring.thymeleaf.check-template-location=true
spring.thymeleaf.suffix=.html                       // 配置视图解析器后缀
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.mode=HTML5

#修改tomcat post提交时的文件大小限制
spring.servlet.multipart.enabled=true
spring.servlet.multipart.max-file-size=300MB        // 配置上传文件大小和请求文件最大
spring.servlet.multipart.max-request-size=215MB

#配置文件上传路径
File.UpliadFilePath=C:\\UploadFiles\\               // 服务器文件保存路径

2、配置文件对应的实体类，后面配置文件中的参数信息获取直接从该类属性而来

package com.tsht.suma.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
public class FileConfig {

    @Value("${File.UpliadFilePath}")
   public String UpliadFilePath;


    public String getUpliadFilePath() {
        return UpliadFilePath;
    }

    public void setUpliadFilePath(String upliadFilePath) {
        UpliadFilePath = upliadFilePath;
    }

}

// 为多文件上传
3、编写Controller

@Controller
public class UploadController {

@Autowired
FileConfig fileConfig;

@RequestMapping("/multiUpload")
@ResponseBody
public String  multiUpload(HttpServletRequest request,HttpServletResponse response){
    List lists = new ArrayList();
    // 从配置文件中获取上传到服务器的路径
    String filePath = fileConfig.getUpliadFilePath();
    //System.out.println(filePath);
    MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest)request;
    MultiValueMap multiValueMap = multipartHttpServletRequest.getMultiFileMap();
    for(MultiValueMap.Entry> entry: multiValueMap.entrySet()){
        List multipartFiles = entry.getValue();
        for(MultipartFile multipartFile:multipartFiles){
            String filename = multipartFile.getOriginalFilename();
            try {
                multipartFile.transferTo(new File(filePath + filename));
                lists.add(filePath + filename);
                System.out.println("上传成功");
            }catch (IOException e){
                System.out.println(e.getMessage());
            }
        }
    }
    return "";

}

Vue + elementUI:

4、index.heml
引入下载在本地的样式文件和js文件

    
    
    
    
    
    
    





    
        
            
                    


                        
                           
                            
                                       ref="upload"
                                       name="uploadFile"
                                       action="/multiUpload"
                                       :multiple ="true"
                                       :on-preview="handlePreview"
                                       :on-remove="handleRemove"
                                       :on-change="handleChange"
                                       :file-list="fileList"
                                       :auto-upload="true"
                                       :show-file-list="true">
                                选取本地文件
                                
                                上传到服务器
                                
文件列表
                            
                        
                    

            
        

    var Files = [];
    var vue = new Vue({
        el: ‘#app‘,
        data: {
            fileList: Files
        },
        methods:{
            indexMethod: indexMethod,
            selectFiles:selectFiles,
            submitUpload:submitUpload,
            handleRemove:handleRemove,
            handlePreview:handlePreview,
            handleChange:handleChange
        },
        created: function () {

        }
    });

    function handleChange(file, fileList) {
        Files = fileList;
    }

    //移除文件时
    function  handleRemove(file, fileList) {
        console.log(file, fileList);
    }
    //添加文件时
    function handlePreview(file) {
        console.log(file);
    }

    function submitUpload(){

    }

}
