How to upload the file by java?

F.Torres

some of my recent research,I know how to display the file,But the key is I can't get the stream in the server,and the file must save in the database? and must create a table to save the file id、path and so on?

allan

I'm afraid I know next to nothing about Java. You'd need to ask in a Java specific programming forum or StackOverflow about how to read a file from an HTTP upload.

by this code,I can attribute the name and id to the input where type = text
attr:{
name:"imgUrl",
id:"imgUrl"
}
but I can't attribute the input where type = 'file'

F.Torres

by attr id and name,I think I can send the stream to the server

The upload field type is what Editor uses for file upload.

I think the api is to little...
and Should I attr the enctype="multipart/form-data" in the form?
but I can't find

allan

No - the upload field type uses XHR requests to upload the document. Documentation for it is available here.

                    '<img src="'+row.image.webPath+'"/>' :

            },
            noFileText: '没有文件',//没有文件显示的文字
            //drawCallback: function () {
                //var formData = new FormData();
                //formData.append("file",$(jQuery(".upload input"))[0].files[0]);    
                ajax:{
                    url:getRootPath()+"/back/club_course_upload.do",
                    type:"post",
                    action:"upload",
                    uploadField:"imgUrl",
                    upload: $(".upload input")[0],
                    data: {
                        "data": new FormData($(".upload input")[0]),
                        //"url": $(".upload input")[0].value
                    },
                    //contentType: false,
                    success: function (data) {
                        if (data.status == "true") {
                            alert("上传成功！");
                        }
                        if (data.status == "error") {
                            alert(data.msg);
                        }
                        $("#imgWait").hide();
                        alert(data);
                    },
                    error: function (data) {
                        alert(data);
                    }
                }
            //}
            
        }

I don't know what should I write by the upload,It is display the type is the File!

allan

That presumably shows a upload field type and let's you select a file, correct? Then when you select the file it sends the file to getRootPath()+"/back/club_course_upload.do", correct?

I can debug with the path,but I can't get the stream

allan

I don't really know what you mean I'm afraid. The stream in Java? As I say, I know next to nothing about Java - you'd need to ask on StackOverflow or a Java specific forum.

Your answer it's true,my understanding of editor is not deep enough,and it makes me a lot of trouble,thanks by your answer although I often can't express myself clearly.
