java spring maven pdf 導出

pdf表單模板

js : 渲染出動態的html ,其實就是一個a標籤

Visitor.operateFormatter = function(value, row, index) {
    //編輯
    var editButton = '<button type="button" class="btn btn-success btn-xs" onclick="Visitor.openUpdateVisitor(\'' + row.id + '\')" ';
    if($("#visitor_update").val() == undefined){
        editButton += 'disabled="disabled"';
    }
    editButton += '><i class="fa fa-edit"></i>&nbsp;編輯</button>';
    //刪除
    var deleteButton = '<button type="button" class="btn btn-danger btn-xs button-margin" onclick="Visitor.delete(\'' + row.id + '\')" ';
    if($("#visitor_delete").val() == undefined){
        deleteButton += 'disabled="disabled"';
    }
    deleteButton += '><i class="fa fa-remove"></i>&nbsp;刪除</button>';
    //pdf下載
    var pdfButton = '<a href="visitor/exportPDF/' + row.id + '" ';
    pdfButton += '>&nbsp;&nbsp;PDF</a>';

    return [ editButton,deleteButton,pdfButton,].join('');

pdf文件導出進階版

1. pdf文件網頁預覽

2.pdf文件合併

3.刪除項目路徑的pdf

引入pdfjs

js:

WorkOrder.printReceipt = function () {
    if (this.check()) {
        window.open('/static/js/plugins/pdfjs/web/viewer.html?file=' + encodeURIComponent(Feng.ctxPath + "/workOrder/print_receipt/"+ this.ids,"pdf"));
    }
};
//ids 是check 方法裏面把多個id 用都用隔開保存的一個js屬性

controller:

/**
     * @Author Donald
     */
    @Permission
    @RequestMapping(value = "/print_receipt/{ids}")
    @ResponseBody

            List<File> fileList = new ArrayList<>(); // 每頁pdf文件一個file集合
            String path = Class.class.getClass().getResource("/").getPath();

            int workOrderId;
