配置檔案的配置
application.yml
server:
port: 8181
spring:
profiles:
active: pro
# 修改檔案上傳的大小
servlet:
multipart:
enabled: true
file-size-threshold: 0
max-file-size: 100MB
max-request-size: 100MB
application-dev.yml
server: port: 8181 #上傳檔案的配置 upload: # 上傳伺服器的位置 filePath: /Users/wanglichao/Desktop/temp/upload/test/ # 返回的url路徑 fileUrl: /Users/wanglichao/Desktop/temp/upload/test/
application-pro.yml
server:
port: 8181
upload:
filePath: /myapp/upload/image/
fileUrl: http://ip伺服器:8083/image/
啟動類
App.java
package com.wlc; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * Hello world! */ @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
工具類
JsonResult.java統一返回類
package com.wlc.util;
/**
* @author 王立朝
* @description 統一返回類
* @date 2021-12-21 21:56:22
*/
public class JsonResult<T> {
private Integer code;
private String msg;
private Object data;
public JsonResult(Integer code, String msg, Object data) {
this.code = code;
this.msg = msg;
this.data = data;
}
public JsonResult() {
}
public com.wlc.util.JsonResult<T> success(Object data){
com.wlc.util.JsonResult jsonResult = new com.wlc.util.JsonResult<T>();
jsonResult.setCode(200);
jsonResult.setMsg("成功了！");
jsonResult.setData(data);
return jsonResult;
}
public com.wlc.util.JsonResult<T> success(){

jsonResult.setCode(200);
jsonResult.setMsg("成功了！");
return jsonResult;
}
public com.wlc.util.JsonResult<T> error(Integer code, String msg, Object obj){
return new com.wlc.util.JsonResult<T>(code,msg,obj);
}
public Integer getCode() {
return code;
}
public void setCode(Integer code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public Object getData() {
return data;
}
public void setData(Object data) {
this.data = data;
}
}
service介面
UploadService.java
package com.wlc.service;
import com.wlc.util.JsonResult;
import org.springframework.web.multipart.MultipartFile;
/**
* @author 王立朝
* @date 2022/3/9
* @description: 上傳服務介面
*/
public interface UploadService {
/**
* 上傳服務介面
* @param multipartFile
* @return
*/
JsonResult upload(MultipartFile multipartFile);
}
service介面實現類
UploadServiceImpl.java
package com.wlc.service.impl;
import com.wlc.service.UploadService;
import com.wlc.util.JsonResult;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.UUID;
/**

@Service
public class UploadServiceImpl implements UploadService {
private static final Logger logger = LoggerFactory.getLogger(UploadServiceImpl.class);
/**
* 檔案上傳的路徑
*/
@Value("${upload.filePath}")
private String filePath;
/**
* 檔案返回前臺的路徑
*/
@Value("${upload.fileUrl}")
private String fileUrl;
/**
* 上傳服務介面
*
* @param multipartFile
* @return
*/
@Override
public JsonResult upload(MultipartFile multipartFile) {
JsonResult jsonResult;
if (!multipartFile.isEmpty()) {
try {
logger.info("開始上傳功能。。。。");
// 獲取當前日期
String date = LocalDate.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
File file = new File(filePath + date);
if(!file.exists()){
file.mkdir();
}
// 修改檔名稱
String fileName = setFileName(multipartFile.getOriginalFilename());
multipartFile.transferTo(new File(filePath + date + "/" + fileName));
logger.info(filePath + multipartFile.getOriginalFilename());
jsonResult = new JsonResult(200, "上傳成功", fileUrl + date + "/" + fileName);
logger.info("結束上傳功能。。。。");
} catch (Exception e) {
e.printStackTrace();
logger.error("網路異常");
jsonResult = new JsonResult(500, "網路異常", "");
}
} else {
logger.error("上傳失敗！");
jsonResult = new JsonResult(404, "上傳失敗", "");
}
return jsonResult;
}
private String setFileName(String originalFilename) {
// 獲取檔案的字尾名稱
String substring = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
return UUID.randomUUID() + "." + substring;
}
}
controller控制器
UploadController.java
package com.wlc.controller;
import com.wlc.service.UploadService;
import com.wlc.util.JsonResult;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import javax.annotation.Resource;
/**

* @date 2021-12-21 21:52:06
*/
@RestController
public class UploadController {
@Resource
private UploadService uploadService;
@PostMapping("/api/upload")
public JsonResult upload(@RequestParam("userHeaderPicture") MultipartFile multipartFile) {
