controller代码:

package com.hf.uncompress.controller;

import org.springframework.web.bind.annotation.*;

import org.springframework.web.multipart.MultipartFile;

/**

@Controller

@RequestMapping("/user")

@Slf4j

public class FileUploadController {

@Autowired

private FileUploadService fileUploadService;

@GetMapping("/redirect")

public String redirectHtml() {

return "work";

}

@PostMapping("/upload/zip")

@ResponseBody

public String uploadZip(MultipartFile zipFile, @RequestBody PackParam packParam) {

AjaxListajaxList = 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 java.io.File;

import java.io.IOException;

/**

* @Description:

@Service

@Slf4j

public class FileUploadServiceImpl implements FileUploadService {

@Override

public AjaxListhandlerUpload(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);

} 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: 2019/1/22

* @Auther:

*/

@AllArgsConstructor

@NoArgsConstructor

public 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: 2019/1/22

* @Auther:

*/

@AllArgsConstructor

@NoArgsConstructor

@Data

public class AjaxList{

private boolean isSuccess;

private T data;

public static AjaxListcreateSuccess(T data) {

return new AjaxList(true, data);

}

public static AjaxListcreateFail(T data) {

return new AjaxList(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: 2019/1/23

* @Auther:

*/

@Data

public 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=500MB

spring.thymeleaf.cache=false
