标签:log nts Servle 因此 pre ajax 多个 method save
vue代码(使用element-ui):
思路:依次遍历fileList数组,将其中的每个图片文件提取出,再加入到formdata中,因为是多文件上传,后端以文件数组的形式接受,
因此每次合并到formdata的key值都为同一值。
uploadImg() {
let imgfile = new FormData();
for (var i = 0; i < this.fileList.length; i++) {
// files[i] = this.fileList[i].raw;
imgfile.append("files",this.fileList[i].raw);
}
// console.log("文件长度",files.length);
imgfile.append("id",this.radio);
console.log("将要上传的文件:",imgfile.get("files"));
if (this.fileList.length > 0) {
this.$ajax({
method: "post",
url: "/xxxx/xxxx/xxxxxxxx/productImg",
data: imgfile
}).then(resp => {
console.log("返回值:",resp.data.code)
if (resp.data.code) {
this.$message({
message: "上传药材图片成功",
type: "success"
});
} else {
this.$message({
message: "上传药材图片失败",
type: "warning"
})
}
this.cleanImg();
this.dialogUploadPhoto = false;
})
} else {
this.$message({
message: "请选择需要上传的图片",
type: "warning"
});
}
}
后端代码:
Controller:
@PostMapping("productImg")
public ResponseEntity<Map<String,Object>> uploadImg(@RequestParam("files")MultipartFile[] files, HttpServletRequest request, @RequestParam Map<String, Object> map) {
return ResponseEntity.status(HttpStatus.CREATED).body(productBaseService.saveImg(files,request,map));
}
service:
@Override
public Map<String, Object> saveImg(MultipartFile[] files, HttpServletRequest request, Map<String, Object> map) {
Map<String,Object> maps = new HashMap<String, Object>();try {
// 判断文件数组是否为空
if (files == null || files.length < 1) {
maps.put("code",false);
} else {
System.out.println("有数据");
//判断是否有路径
String path = Constant.IMG_PATH_FILE;
if (!new File(path).exists()) {
new File(path).mkdirs();
}
// 遍历图片文件
for (int i = 0; i < files.length; i++) {
MultipartFile file = files[i];
// 将图片文件保存到服务器,同时返回上传后图片的名字
String image = uploadFile(file,path,map);
ProductBaseImg productBaseImg = new ProductBaseImg();
productBaseImg.setId(UUIDUtil.uuid());
productBaseImg.settImgId(image);
productBaseImg.settProductbaseId((String)map.get("id"));
productBaseImgMapper.insert(productBaseImg);
System.out.println("上传成功");
}
maps.put("code",true);
}
} catch (IOException e) {
maps.put("code",false);
e.printStackTrace();
}
return maps;
}
public static String uploadFile(MultipartFile file,String path,Map<String, Object> map) throws IOException {
String name = file.getOriginalFilename();
String suffixName = name.substring(name.lastIndexOf("."));
// 生成图片id
String imgid = UUIDUtil.uuid();
String fileName = imgid + suffixName;
File tempFile = new File(path,fileName);
if(!tempFile.getParentFile().exists()){
tempFile.getParentFile().mkdir();
}
if(tempFile.exists()){
tempFile.delete();
}
tempFile.createNewFile();
file.transferTo(tempFile);
return tempFile.getName();
}
vue使用formdata上传多个图片,springboot以文件数组的形式接受
