一、背景　　

　　前段时间，LZ的boss突然给了出了这样一个需求：将原项目中的所有文章关联的附件TXT、PDF、office相关文件全部以flash的形式在网页上进行展示，便于预览。看似简单的需求，整个研发小组都懵逼的。LZ也没办法只好Google一把，找了好几套解决方案，基本上是调第三方软件的API，像什么flashpaper、print2flash等等。LZ先试了flashpaper，反正是各种问题，不支持64位系统什么的；print2flash在版本4以前也是很多问题，dll调用失败，dll缺失。最终，LZ在官网下载了最新的版本（商业软件，收费的），用起来还是相对来说比较稳定，至今没出现问题。提供的API还是比较丰富的，本篇LZ主要介绍java和.NET的操作。

二、print2flash安装

　　这里LZ为了简单实验主要介绍破解版的安装（费了好大的力才找到的），如果商用，还是给钱找别人买吧。

　　1）下载print2flash4.如果想使用服务器模式，大概需要600刀，也不是很贵。官网地址

　　2）运行print2flashsetup.exe一直下一步就OK。

　　3）下载补丁文件。共3个文件p2fServer.exe，print2f4.exe，Print2FlashPrinter4.dll；如果之前已设置了windows服务方式启动，则先需要停止Print2Flash4服务；拷贝p2fServer.exe、print2f4.exe到安装目标文件夹替换原文件，拷贝Print2FlashPrinter4.dll到以下文件夹替换原始文件：C:\Windows\System32\spool\drivers\x64\以及C:\Windows\System32\spool\drivers\x64\3\

　　4）注册print2flash4服务。运行print2flash，options->print2flash service configuration,输入Windows密码，没有的话就不用输，勾选Grant access and launch pemmissions to Everyone给EveryOne用户授予权限。点击OK，如果提示successful，Current status显示Installed表示安装成功。

　　5）开启print2flash4服务。安装成功后，在windows服务中可以找到print2flash服务。启动该服务。

三、java操作API

　　开始前我们需要将print2flash提供的SDK中的P2FConst.java引入：

1 public class P2FConst  2 {  3     // 枚举常量  4     public static final int MSEXCEL = 0x00000001;  5     public static final int MSWORD = 0x00000002;  6     public static final int MSPOWERPOINT = 0x00000004;

68     public static final int IMGSELTEXT = 3; 69     public static final int IMGZOOMRULER = 4; 70     public static final int IMGZOOMFOCUSNADLE = 5; 71     public static final int IMGZOOMNADLE = 6; 72     public static final int IMGFITWIDTH = 7; 73     public static final int IMGFITPAGE = 8; 74     public static final int IMGPREVPAGE = 9; 75     public static final int IMGNEXTPAGE = 10; 76     public static final int IMGSEARCHBUT = 11; 77     public static final int IMGROTATE = 12;

83     public static final int IMGBACK = 18; 84     public static final int IMGFORWARD = 19; 85     public static final int IMGFULLSCREEN = 20; 86     public static final int IMGEXITFULLSCREEN = 21; 87  88     // TEMPLATETYPE enumeration constants 89     public static final int TEMPLATE_CUSTOM = 1; 90     public static final int TEMPLATE_ACTIONSCRIPT2 = 2; 91     public static final int TEMPLATE_ACTIONSCRIPT3 = 3; 92  93     // WATERMARKANCHOR enumeration constants 94     public static final int CENTER = 0;

　　开始转换Test.java类：

1 package print2flash; 2  3 import java.io.IOException; 4  5 import com.jacob.activeX.*; 6 import com.jacob.com.*; 7  8 public class Test { 9 10     public static void main(String[] args) throws IOException {11         try {12             ComThread.InitSTA();//com组件管理，用来初始化com线程，释放线程13             ActiveXComponent p2f = new ActiveXComponent("Print2Flash4.Server");//创建print2flash的一个应用，调用print2flash服务14             //设置属性值，可根据自己需求修改15             ActiveXComponent defProfile = new ActiveXComponent(p2f.getProperty("DefaultProfile").toDispatch());16             defProfile.setProperty("InterfaceOptions", P2FConst.INTLOGO | P2FConst.INTZOOMSLIDER | P2FConst.INTPREVPAGE17                     | P2FConst.INTGOTOPAGE | P2FConst.INTNEXTPAGE);18             defProfile.setProperty("ProtectionOptions", P2FConst.PROTDISPRINT | P2FConst.PROTENAPI);19             defProfile.setProperty("DocumentType", P2FConst.FLASH | P2FConst.HTML5);20             p2f.invoke("ConvertFile", "E:/print2flashTest/test.doc");//方法调用21             System.out.println("转换成功！");22         } catch (Exception e) {23             System.out.println("转换异常: " + e.toString());24         } finally {25             ComThread.Release();26         }27     }28 }

　　注意：这里涉及到java应用调用windows的COM组件，需要用到jacob，没有的同学，可以用LZ提供的链接地址下载（文章最后会一起附上）。

　　1）将jacob.jar build path。

　　2）将jacob-1.16-M1-x64.dll（根据自己系统情况选择）复制到jre/bin目录（如果没有该dll，会抛出找不到ComThread类异常）

　　接下来LZ准备一个test.doc，来进行测试:

　　test.docx.swf即为生成的flash文件，可嵌入到你需要的网页中。

四、.NET操作API

　　.NET的操作相对来说就简单得多了，LZ这里也是只做一个简单的win32控制台演示：

　　1）首先新建win32控制台应用程序，增加程序集Interop.Print2Flash4.dll。

　　2）在Proogram.cs中写具体业务逻辑：　　

1 using System; 2 using System.Collections.Generic; 3 using System.IO; 4 using System.Linq; 5 using System.Text; 6  7 namespace Test 8 { 9     class Program10     {11         static void Main(string[] args)12         {13             string fs_filename = System.AppDomain.CurrentDomain.BaseDirectory()+"/print2flashTest/test.docx";14             string fs_convertedfilename = System.AppDomain.CurrentDomain.BaseDirectory()+"/print2flashTest/swf/test.swf";15             Print2Flash4.Server2 p2fServer = new Print2Flash4.Server2();//创建print2flash对象16             //设置参数值，可以参考官网SDK文档          17             p2fServer.ConvertFile(fs_filename, fs_convertedfilename, null, null, null);18         }19     }20 }

　　运行结果与java一样。官网SDK还提供了ASP、PHP等脚本语言的操作API，有情趣的同学可以自己尝试一下。

五、总结

　　print2flash这款软件还是不错的，转换后的效果比较清晰。运用范围差不多就是内容管理系统、文章管理等附件的预览，当然也可以用来控制游客用户不允许文字复制等等。最后附上本文LZ所用到的源代码，补丁，附件的下载地址：
