controller代码:
package com.hf.uncompress.controller;import com.hf.uncompress.Result.AjaxList;import com.hf.uncompress.service.FileUploadService;import com.hf.uncompress.vo.PackParam;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.*;import org.springframework.web.multipart.MultipartFile;/*** @Description:* @Date: /1/22* @Auther: */@Controller@RequestMapping("/user")@Slf4jpublic class FileUploadController {@Autowiredprivate FileUploadService fileUploadService;@GetMapping("/redirect")public String redirectHtml() {return "work";}@PostMapping("/upload/zip")@ResponseBodypublic String uploadZip(MultipartFile zipFile, @RequestBody PackParam packParam) {AjaxList<String> ajaxList = fileUploadService.handlerUpload(zipFile, packParam);return ajaxList.getData();}}
service实现类代码
package com.hf.uncompress.service.impl;import com.hf.uncompress.Result.AjaxList;import com.hf.uncompress.enums.FileTypeEnum;import com.hf.uncompress.service.FileUploadService;import com.hf.uncompress.utils.UnPackeUtil;import com.hf.uncompress.vo.PackParam;import lombok.extern.slf4j.Slf4j;import org.springframework.stereotype.Service;import org.springframework.web.multipart.MultipartFile;import java.io.File;import java.io.IOException;/*** @Description:* @Date: /1/22* @Auther: */@Service@Slf4jpublic class FileUploadServiceImpl implements FileUploadService {@Overridepublic AjaxList<String> handlerUpload(MultipartFile zipFile, PackParam packParam) {if (null == zipFile) {return AjaxList.createFail("请上传压缩文件!");}boolean isZipPack = true;String fileContentType = zipFile.getContentType();//将压缩包保存在指定路径String packFilePath = packParam.getDestPath() + File.separator + zipFile.getName();if (FileTypeEnum.FILE_TYPE_ZIP.type.equals(fileContentType)) {//zip解压缩处理packFilePath += FileTypeEnum.FILE_TYPE_ZIP.fileStufix;} else if (FileTypeEnum.FILE_TYPE_RAR.type.equals(fileContentType)) {//rar解压缩处理packFilePath += FileTypeEnum.FILE_TYPE_RAR.fileStufix;isZipPack = false;} else {return AjaxList.createFail("上传的压缩包格式不正确,仅支持rar和zip压缩文件!");}File file = new File(packFilePath);try {zipFile.transferTo(file);} catch (IOException e) {log.error("zip file save to " + packParam.getDestPath() + " error", e.getMessage(), e);return AjaxList.createFail("保存压缩文件到:" + packParam.getDestPath() + " 失败!");}if (isZipPack) {//zip压缩包UnPackeUtil.unPackZip(file, packParam.getPassword(), packParam.getDestPath());} else {//rar压缩包UnPackeUtil.unPackRar(file, packParam.getDestPath());}return AjaxList.createSuccess("解压成功");}}
使用到的枚举类:
package com.hf.uncompress.enums;import lombok.AllArgsConstructor;import lombok.NoArgsConstructor;/*** @Description: 压缩文件类型* @Date: /1/22* @Auther:*/@AllArgsConstructor@NoArgsConstructorpublic enum FileTypeEnum {FILE_TYPE_ZIP("application/zip", ".zip"),FILE_TYPE_RAR("application/octet-stream", ".rar");public String type;public String fileStufix;public static String getFileStufix(String type) {for (FileTypeEnum orderTypeEnum : FileTypeEnum.values()) {if (orderTypeEnum.type.equals(type)) {return orderTypeEnum.fileStufix;}}return null;}}
同一返回值定义:
package com.hf.uncompress.Result;import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;/*** @Description: 返回值处理* @Date: /1/22* @Auther: */@AllArgsConstructor@NoArgsConstructor@Datapublic class AjaxList<T> {private boolean isSuccess;private T data;public static <T> AjaxList<T> createSuccess(T data) {return new AjaxList<T>(true, data);}public static <T> AjaxList<T> createFail(T data) {return new AjaxList<T>(false, data);}}
前端上传封装的vo
package com.hf.uncompress.vo;import lombok.Data;/*** @Description: 上传压缩的参数* @Date: /1/23* @Auther: */@Datapublic class PackParam {/*** 解压密码*/private String password;/*** 解压文件存储地址*/private String destPath;}
在application.properties中定义其上传的阀域
#设置上传单个文件的大小限制spring.servlet.multipart.max-file-size=500MB# 上传文件总的最大值spring.servlet.multipart.max-request-size=500MBspring.thymeleaf.cache=false
