Springboot MultipartFile ajax提交java檔案上傳
ecplise
jdk 1.8
一。配置資訊
pom.xml 檔案引入以來依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 檢視解析Thymeleaf -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
2、springboot 啟動類Application
增加@EnableAutoConfiguration(exclude = {MultipartAutoConfiguration.class})
3、application.yml檔案
增加檔案大小限制，上傳的根目錄
multipart:
enabled: true
max-file-size: 50mb
max-request-size: 50mb
上傳的根目錄
#公用變數，方便更改
publicvariable:
#專案圖片儲存路徑
imglocation: /Users/wangdeqiu/Documents/fileUpload
二、index.html頁面提交上傳檔案
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Title</title>
<!-- <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> -->
<meta http-equiv="Content-Type" content="multipart/form-data; charset=utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10, chrome=1" />
<script src="/js/jquery.js"></script>
</head>
<body>
<form id="uploadForm" enctype="multipart/form-data">
檔案:<input id="file" type="file" name="file" text="點選我上傳圖片" />
</form>
<button id="upload">上傳檔案</button>
<script type="text/javascript">
$(function () {
$("#upload").click(function () {
var fileObj = document.getElementById("file").files[0]; // js 獲取檔案物件
var tokenv="ssssssss";
//var data = {"token":token,"file":fileObj};
var formData = new FormData();
formData.append("file",fileObj);
formData.append("token",tokenv);
$.ajax({
url: 'http://localhost:8080/test/upload',
type: 'POST',
cache: false,
data: new FormData($('#uploadForm')[0]),
processData: false,
contentType: false
}).done(function(res) {
//列印返回值資訊
alert(res);
}).fail(function(res) {
alert("上傳失敗");
});
});
});
</script>
</body>
</html>
三、Java controller 接受引數，呼叫service
@Controller
@RequestMapping("test")
public class TestBootController {
//日誌列印
private final Logger log = LoggerFactory.getLogger(TestBootController.class);
@Autowired
private FileUploadService fileUploadService;
Logger logger = LoggerFactory.getLogger(TestBootController.class);
@RequestMapping("/")
public String home() {
return "app/index";
}
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
public Map<String,Object> saveUploadFile( @RequestParam("file") MultipartFile file,HttpServletRequest request) {
Map<String,Object> output = new HashMap<String,Object>();
String fileName = file.getOriginalFilename();
System.out.println("獲取....fileName.."+fileName);
try {
String fileType = "合同";
UploadFile fileEntity = fileUploadService.uploadFile(file,fileType);
System.out.println("setfileName顯示的檔名"+fileEntity.getFileName());
System.out.println("setFilePath檔案路徑"+fileEntity.getFilePath());
System.out.println("setRealName真正的檔名"+fileEntity.getRealName());
System.out.println("setSuffix檔案字尾"+fileEntity.getSuffix());
} catch (IllegalStateException e) {
logger.error("檔案上傳錯誤", e.getMessage());
e.printStackTrace();
throw e;
} catch (IOException e) {
logger.error("檔案上傳錯誤", e.getMessage());
e.printStackTrace();
} catch (Exception e) {
output.put("msg", "上傳失敗");
e.printStackTrace();
}
return output;
}
}
2、Servie 檔案上傳
package com.haidaipuhui.service.common;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.UUID;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import com.haidaipuhui.domain.common.UploadFile;
import com.haidaipuhui.util.FileUploadUtil;
/**
* @date 2018年7月30日 下午2:06:39
* 類說明:檔案的上傳與下載
*/
@Service
public class FileUploadService {
@Value("${publicvariable.imglocation}")
private String rootPath;//檔案根路徑
/**
*
* Desc:檔案上傳
* @author wangdeqiu
* @date 2018年7月30日 下午2:08:33
* @return
* @param file 上傳的檔案
* @param fileType 根據累心建立資料夾 例如：合同，企業資料。
* @throws Exception
*/
public UploadFile uploadFile(MultipartFile file,String fileType) throws Exception {
UploadFile fileEntity = new UploadFile();
if (file.isEmpty() || StringUtils.isBlank(file.getOriginalFilename())) {
throw new Exception();
}
String[] fileItem = file.getOriginalFilename().split("\\.");
String uuid_name = UUID.randomUUID().toString();
String relativePath = FileUploadUtil.getUploadPath()+FileUploadUtil.flag;
String filePath = rootPath+"/"+fileType+"/"+relativePath+uuid_name+"."+fileItem[1];
String path = rootPath+"/"+fileType+"/"+relativePath;//根目錄+型別+時間
// File targetFile = new File(path);
// if(!targetFile.exists()){
// targetFile.mkdirs();
// }
// file.transferTo(targetFile);
File tarFile = new File(path);
if (!tarFile.exists()) {
tarFile.mkdirs();
}
String fileName = uuid_name+"."+fileItem[1];
FileInputStream fileInputStream = (FileInputStream) file.getInputStream();
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(path + File.separator + fileName));
byte[] bs = new byte[1024];
int len;
while ((len = fileInputStream.read(bs)) != -1) {
bos.write(bs, 0, len);
}
bos.flush();
bos.close();
fileEntity.setFileName(fileItem[0]);
fileEntity.setRealName(uuid_name);
fileEntity.setFilePath(relativePath);
fileEntity.setSuffix(fileItem[1]);
return fileEntity;
}
}
3、FileUploadUtil
package com.haidaipuhui.util;
import java.util.Calendar;
import java.util.Date;
public class FileUploadUtil {
public static final String flag = "/";
/**
* @title getUploadPath
* @Description: 獲取日月年資料夾路徑
*/
public static String getUploadPath(){
Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date());
String yearPath = Integer.toString(calendar.get(Calendar.YEAR));
String monthPath = Integer.toString(calendar.get(Calendar.MONTH)+1);
String datePath = Integer.toString(calendar.get(Calendar.DAY_OF_MONTH));
return flag+yearPath+flag+monthPath+flag+datePath+flag;
}
}
