dhtmlx uploader使用

前端:
{type : "upload", mode : "html4", name : "importFile", inputWidth : 300, url : "/base/baseSkuProp/import"}

fileForm.attachEvent("onUploadComplete", function() {
    alert("导入成功");
});

fileForm.attachEvent("onUploadFail", function(fileName, extra) {
    alert(extra.msg);
});

后端：

@RequestMapping("/import")
public String importExcel(MultipartFile file) {
    try {
        //处理file...

        return "{state : true, name : '" + file.getOriginalFilename() + "', size : " + file.getSize() + "}";

    } catch (Exception e) {
        e.printStackTrace();
        return "{state : 'fail', extra : {msg : '" + e.getMessage() + "'}}";
    }
}
