前提是你 提交于 2020-01-15 23:36:01
问题 I am stuck in a Java application. I have a doubt that is there any way to convert HTML template to DOC Template with Image in HTML file using Java. I have tried Aspose API but I cant use it because it is not open. I fetch HTML template from database and store the whole template into string and now I want this string output in a WORD DOC including the images. Here is my piece of code: proc_stmt = con.prepareCall("{call PROCEDURECALL(?)}"); proc_stmt.registerOutParameter(1, Types.CLOB); proc

原型模式

十年热恋 提交于 2020-01-15 01:55:20
个人博客 http://www.milovetingting.cn 原型模式 模式介绍 原型模式是一个创建型的模式。多用于创建复杂的或者构造耗时的实例,因为这种情况下,复制一个已经存在的实例,可使程序运行更高效。 模式定义 用原型实例指定创建对象的种类,并通过复制这些原型创建新的对象。 使用场景 类初始化需要消耗非常多的资源 通过new产生一个对象需要非常繁琐的数据准备或访问权限 一个对象需要提供给其它对象访问,而且各个调用者可能都需要修改值 通过实现Cloneable接口的原型模式在调用clone函数构造实例时,并不一定比通过new操作速度快,只有当通过new构造函数对象较为耗时或成本较高时,通过clone方法才能够获得效率上的提升。 简单实现 以简单的文档拷贝为例演示简单的原型模式。 先来演示浅拷贝 文档定义 public class Document implements Cloneable { private String mText; private ArrayList<String> mImages = new ArrayList<>(); public String getmText() { return mText; } public void setmText(String mText) { this.mText = mText; } public List

Print PDF file and Doc file using C#

问题 In my application I'm trying to create a function to print existing PDFs or Doc. How can I do this in C# and provide a mechanism so the user can select a different printer or other properties. I've looked at the PrintDialog but not sure what file it is attempting to print, if any, b/c the output is always a blank page. Maybe I'm just missing something there. Any advice, examples or sample code would be great! The below is my code using System; using System.Collections.Generic; using System

一、前言 写博客,更要努力写博客! 二、Mapping介绍 Mapping类似于数据库中的表结构的定义:这里我们试想一下表结构定义需要那些: 1.字段和字段类型,在Elasticsearch中的体现就是索引的结构,定义索引的字段Field Name和字段类型,上一篇有简单介绍一下字段有那些类型; 2.索引,在数据库中我们可以定义字段索引,在Elasticsearch中就是相当于是否分词,按照分词器分词; 先来用我们的神器先自定义一个Mapping: 接下来在在查询下Mapping的结构: 三 、Mapping常用参数介绍 type:指定参数的类型; analyzer:指定分词器; boost:指定字段的权重, copy_to:指定某几个字段合并; dynamic:字段动态添加 ,有3种取值: true:无限制; false:数据可写入但该字段不保留; strict:无法写入抛异常; format:"yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis" ,格式化 此参数代表可接受的时间格式 3种都接受; ignore_options:这个选项用于控制倒排索引记录的内容,有4种配置: docs:只记录文档号; freqs:文档号 + 词频; postions:文档号 + 词频 + 位置; offsets:文档号 + 词频 + 位置 + 偏移量;

前段时间,有一朋友咨询我,说es的head插件一直安装失败,为了给朋友解惑,自己百度博文并实践了一番,也的确踩了些坑,但我给爬了起来。今天就来分享下实践心得并跳过的坑。 ElasticSearch 是一个分布式、高扩展、高实时的搜索与数据分析引擎,它能很方便的使大量数据具有搜索、分析和探索的能力,简称es。本文分五部分描述,es的安装,head插件安装,es的基本概念,es的基本使用,问题总结。 目录 es安装 head插件安装 es基本概念 es基本使用 问题总结 一、es安装 安装方式网络上有很多,这里简单说下步骤,具体实践是很简单的 ①配置java环境 需要java环境,最好是较新的java环境,java环境的配置就略过了 ②安装elasticsearch 下载地址: https://www.elastic.co/cn/downloads/elasticsearch ,最新版本已是7.2.0。下载后,解压到任意目录,我的路径是:D:\elasticsearch-7.2.0 ③启动elasticsearch es的配置文件在config目录下,常用配置在elasticsearch.yml文件。我这里只是做学习目的,所以不修改此文件而直接启动es。在windows环境下启动es方法为命令行进入到bin\目录下,执行elasticsearch.bat,或者双击此文件以启动es。

How to create and save a .rtf, .doc, .docx in Objective-C for iOS

问题 I am looking to create and save either a rtf, doc or docx file on an iPad (iOS). The scenario is that we'd like to assist a user in creating content on their iPad and then let them email this as an editable document cross-platform (OS X, WIN). I am open to other solutions besides the rtf, doc or docx file format. Thanks, James 回答1: RTF is going to be the easiest, because it's a plain text format. It's kind of like HTML, but without closing tags. Here is a class for writing an RTF, but it

How to convert HTML to a Microsoft Word document ?

问题 How can I convert HTML from a CKEditor into a Microsoft Word document? 回答1: CKEditor is just HTML, so what you really should be asking yourself is: How do I save CKEditor contents as an HTML file and then convert that into a .doc file. The answer to the first part should be trivial. Protip: You send the contents as a string to your backend and your backend writes that string to an .html file. As for the conversion, you can try saving the content as a .html file, then opening that in Word and
