環境配置

使用kindeditor元件實現

1.新增依賴
加入commons-fileupload

2.在SpirngMVC配置檔案中編寫CommonsMultipartResolver

上傳元件js的實現

kindeditor元件初始化

頁面載入時初始化圖片上傳元件

 // 初始化圖片上傳元件
    initPicUpload : function(data){
        $(".picFileUpload").each(function(i,e){
            var _ele = $(e);
            _ele.siblings("div.pics"
 
).remove();
            _ele.after('\
                <div class="pics">\
                    <ul></ul>\
                </div>');
            // 回顯圖片
            if(data && data.pics){
                var imgs = data.pics.split(",");
                for(var i in imgs){
                    if
 
($.trim(imgs[i]).length > 0){
                        _ele.siblings(".pics").find("ul").append("<li><a href='"+imgs[i]+"' target='_blank'><img src='"+imgs[i]+"' width='80' height='50' /></a></li>");
                    }
                }
            }
            $(e).click(function
 
(){
                var form = $(this).parentsUntil("form").parent("form");
                KindEditor.editor(TT.kingEditorParams).loadPlugin('multiimage',function(){
                    var editor = this;
                    editor.plugin.multiImageDialog({
                        clickFn : function(urlList) {
                            var imgArray = [];
                            KindEditor.each(urlList, function(i, data) {
                                imgArray.push(data.url);
                                form.find(".pics ul").append("<li><a href='"+data.url+"' target='_blank'><img src='"+data.url+"' width='80' height='50' /></a></li>");
                            });
                            form.find("[name=image]").val(imgArray.join(","));
                            editor.hideDialog();
                        }
                    });
                });

解決圖片回顯的問題

一般使用代理伺服器處理靜態資源
需要配置nginx

配置host
