pdf表单模板

js : 渲染出动态的html ,其实就是一个a标签

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

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

maven 加载的jar包

        <!--pdf 导出需要的jar包 -->
        <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>

pdf文件导出进阶版

1. pdf文件网页预览

2.pdf文件合并

3.删除项目路径的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 方法里面把多个id 用都用隔开保存的一个js属性

controller:

/**
     * @Author Donald
     */
    @Permission
    @RequestMapping(value = "/print_receipt/{ids}")
    @ResponseBody
    public void printReceipt(@PathVariable String ids){
        try {
            String workOrderIds[] = ids.split(","); //运单id数组
            List<File> fileList = new ArrayList<>(); // 每页pdf文件一个file集合
            String path = Class.class.getClass().getResource("/").getPath();
            path = path.replace("/target/classes/","/src/main/webapp/static/file/"); //读取模板的文件夹路径
            int workOrderId;
            //遍历运单
            for(int i = 0 ;i < workOrderIds.length; i++) {
