使用PageOffice实现文档（word,excel,pdf）在线预览编辑[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

最近发现一款不错的插件的PageOffice,地址是：http://www.zhuozhengsoft.com/Technical/  他可以实现word,excel、pdf在线预览以及在线编辑。虽然商用的话需要收费，但是有免费的试用版，在实现自己毕业设计或是做样品的时候 是一个不错的选择。他同时支持java\c#\php.一旦有了正真的项目花钱再买也可以。同时自己也可以熟悉如何使用。接着下面实现在线预览。

首先自己需要安装PageOffice控件目前最新版本是4.2 。下载地址是：http://www.zhuozhengsoft.com/dowm/ 其中包括实例代码。

1、安装完后需要给自己的项目添加pageoffice4.jar 和java 添加jar包没有区别。

2、启动的时候第一次使用试用版会弹出一个框，需要添加一些信息，有一个序列号在最后我写了。剩下那个就是随便填写就可以。同时他会生成一个文件就是license.lic。他会在tomcat 项目部署的lib下。假如每次启动都需要添加的话。你就需要把tomcat 部署项目lib 里的license.lic 复制到你的本地项目中。

3、预览后台代码：

	public String openbar(HttpServletRequest request, HttpServletResponse response, @PathVariable int id,
			@PathVariable int flag) {
		// 设置PageOffice服务器组件
		PageOfficeCtrl poCtrl1 = new PageOfficeCtrl(request);
		request.setAttribute("poCtrl1", poCtrl1);
		poCtrl1.setServerPage(request.getContextPath() + "/poserver.zz"); // 此行必须
		poCtrl1.setTitlebar(false); // 隐藏标题栏(pageoffice的标题)
		poCtrl1.setMenubar(false); // 隐藏菜单栏（文件一个设置）
		poCtrl1.setOfficeToolbars(false);// 隐藏Office工具条（word 的编辑按钮）
		// poCtrl1.setCustomToolbar(false);// 隐藏自定义工具栏（保存 关闭 全屏）
		poCtrl1.addCustomToolButton("打印", "ShowPrintDlg()", 6);
		poCtrl1.addCustomToolButton("全屏切换", "SwitchFullScreen()", 4);
		poCtrl1.addCustomToolButton("关闭", "close", 21);
		List<FileMeta> entity = fileMetaService.getList(getEntity(flag, id));
		String path = ZipService.getPath(entity.get(0));
		String realpath = path.replace("/", "\\\\");
		String suffix = path.substring(path.lastIndexOf(".") + 1);
		if ("doc".equals(suffix) || "docx".equals(suffix)) {
			poCtrl1.webOpen(realpath, OpenModeType.docReadOnly, "张三");
		} else if ("xls".equals(suffix) || "xlsx".equals(suffix)) {
			poCtrl1.webOpen(realpath, OpenModeType.xlsReadOnly, "张三");
		}
		// 打开文件
		return "OpenWord";
	}

4’、在线编辑：

/**
	 * 在线编辑
	 * 
	 * @param request
	 * @param response
	 * @param id
	 * @param flag
	 * @return
	 */
	@RequestMapping("openword/{flag}/{id}")
	public String openword(HttpServletRequest request, HttpServletResponse response, @PathVariable int id,
			@PathVariable int flag) {
		PageOfficeCtrl poCtrl = new PageOfficeCtrl(request);
		request.setAttribute("poCtrl", poCtrl);
		poCtrl.setTitlebar(false);
		// 设置服务页面
		poCtrl.setServerPage(request.getContextPath() + "/poserver.zz");
		// 添加保存按钮
		poCtrl.addCustomToolButton("保存并关闭", "Save", 1);
		poCtrl.addCustomToolButton("打印", "ShowPrintDlg()", 6);
		poCtrl.addCustomToolButton("全屏切换", "SwitchFullScreen()", 4);
		// 设置保存的action
		poCtrl.setSaveFilePage(request.getContextPath() + "/wep/savefile/" + flag);
		// 打开word
		List<FileMeta> entity = fileMetaService.getList(getEntity(flag, id));
		String path = ZipService.getPath(entity.get(0));
		String realpath = path.replace("/", "\\\\");
		String suffix = path.substring(path.lastIndexOf(".") + 1);
		if ("doc".equals(suffix) || "docx".equals(suffix)) {
			poCtrl.webOpen(realpath, OpenModeType.docNormalEdit, "张三");
		} else if ("xls".equals(suffix) || "xlsx".equals(suffix)) {
			poCtrl.webOpen(realpath, OpenModeType.xlsNormalEdit, "张三");
		}
		return "Word";
	}

5、在线编辑需要保存，所以有在线保存：

/**
	 * 保存
	 * 
	 * @param request
	 * @param response
	 * @param flag
	 */
	@RequestMapping("savefile/{flag}")
	public void savefile(HttpServletRequest request, HttpServletResponse response, @PathVariable int flag) {
		FileSaver fs = new FileSaver(request, response);
		if (flag == 1) {// hse 保存路径
			fs.saveToFile("D:\\Demo\\conhse\\" + fs.getFileName());
		} else if (flag == 2) {
			fs.saveToFile("D:\\Demo\\doc\\" + fs.getFileName());
		} else if (flag == 3) {
			fs.saveToFile("D:\\Demo\\hsequa\\" + fs.getFileName());
		} else if (flag == 4) {
			fs.saveToFile("D:\\Demo\\eva\\" + fs.getFileName());
		} else if (flag == 5) {
			fs.saveToFile("D:\\Demo\\leg\\" + fs.getFileName());
		} else if (flag == 6) {
			fs.saveToFile("D:\\Demo\\plan\\" + fs.getFileName());	
		}
		fs.close();
	}

6、web-xml配置

<!-- PageOffice Begin -->
	<servlet>
		<servlet-name>poserver</servlet-name>
		<servlet-class>com.zhuozhengsoft.pageoffice.poserver.Server</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>poserver</servlet-name>
		<url-pattern>/poserver.zz</url-pattern>

	</servlet-mapping>
	<mime-mapping>

	</mime-mapping>
	<context-param>
		<param-name>adminseal-password</param-name>
		<param-value>111111</param-value>
	</context-param>
	<!-- PageOffice End -->

7、jsp配置

<%@ page language="java"
	import="java.util.*,com.zhuozhengsoft.pageoffice.*"
	pageEncoding="UTF-8"%>
<%
	PageOfficeCtrl poCtrl = (PageOfficeCtrl) request.getAttribute("poCtrl");
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>最简单的打开保存Word文件</title>
<!-- <script type="text/javascript" >
function getPageOfficeJsUrl(){var d=document.URL;var c=d.substring(0,find(d,"/",3)+1);var a=d.substring(0,find(d,"/",4)+1);var f=new Array();f[0]=c;f[1]=a;for(var b=0;b<f.length;b++){var e="pageoffice.js";ajax({url:f[b]+"/pageoffice.js",type:"GET",data:{name:"super"},dataType:"json",success:function(h,k){if(d.indexOf("?")>0){d=d.substring(0,d.indexOf("?"))}var g=countChar(d.substring(f[b].length),"/");for(var i=0;i<g;i++){e="../"+e}alert('src="'+e+'"')},fail:function(g){}})}}function countChar(d,e){var b=0;for(var a=0;a<d.length;a++){if(d.charAt(a)==e){b++}}return b}function find(e,b,c){var a=0;for(var d=0;d<c;d++){a=e.indexOf(b,a+1)}return a}getPageOfficeJsUrl();function ajax(a){a=a||{};a.type=(a.type||"GET").toUpperCase();a.dataType=a.dataType||"json";var c=formatParams(a.data);if(window.XMLHttpRequest){var b=new XMLHttpRequest()}else{var b=new ActiveXObject("Microsoft.XMLHTTP")}b.onreadystatechange=function(){if(b.readyState==4){var d=b.status;if(d>=200&&d<300){a.success&&a.success(b.responseText,b.responseXML)}else{a.fail&&a.fail(d)}}};if(a.type=="GET"){b.open("GET",a.url+"?"+c,false);b.send(null)}else{if(a.type=="POST"){b.open("POST",a.url,false);b.setRequestHeader("Content-Type","application/x-www-form-urlencoded");b.send(c)}}}function formatParams(c){var a=[];for(var b in c){a.push(encodeURIComponent(b)+"="+encodeURIComponent(c[b]))}a.push(("v="+Math.random()).replace(".",""));return a.join("&")};
</script> -->
<script type="text/javascript" src="../../../jquery.min.js"></script>
<script type="text/javascript" src="../../../pageoffice.js" id="po_js_main"></script>
</head>
<body>
	<div style="width: 100%; height: 100%;">
		<%=poCtrl.getHtmlCode("PageOfficeCtrl1")%>
	</div>
	<script type="text/javascript">
		function Save() {
			document.getElementById("PageOfficeCtrl1").WebSave();
			POBrowser.closeWindow();//关闭POBrowser窗口
		}
		function ShowPrintDlg() {
			document.getElementById("PageOfficeCtrl1").ShowDialog(4); //打印对话框
		}
		function SwitchFullScreen() {//全屏
			document.getElementById("PageOfficeCtrl1").FullScreen = !document
					.getElementById("PageOfficeCtrl1").FullScreen;
		}
	</script>
</body>
</html>

注意：有时候jsp 和他的js 不在同一个目录，这时候在jsp页面使用<script type=”text/javascript” >

function getPageOfficeJsUrl(){var d=document.URL;var c=d.substring(0,find(d,”/”,3)+1);var a=d.substring(0,find(d,”/”,4)+1);var f=new Array();f[0]=c;f[1]=a;for(var b=0;b<f.length;b++){var e=”pageoffice.js”;ajax({url:f[b]+”/pageoffice.js”,type:”GET”,data:{name:”super”},dataType:”json”,success:function(h,k){if(d.indexOf(“?”)>0){d=d.substring(0,d.indexOf(“?”))}var g=countChar(d.substring(f[b].length),”/”);for(var i=0;i<g;i++){e=”../”+e}alert(‘src=”‘+e+'”‘)},fail:function(g){}})}}function countChar(d,e){var b=0;for(var a=0;a<d.length;a++){if(d.charAt(a)==e){b++}}return b}function find(e,b,c){var a=0;for(var d=0;d<c;d++){a=e.indexOf(b,a+1)}return a}getPageOfficeJsUrl();function ajax(a){a=a||{};a.type=(a.type||”GET”).toUpperCase();a.dataType=a.dataType||”json”;var c=formatParams(a.data);if(window.XMLHttpRequest){var b=new XMLHttpRequest()}else{var b=new ActiveXObject(“Microsoft.XMLHTTP”)}b.onreadystatechange=function(){if(b.readyState==4){var d=b.status;if(d>=200&&d<300){a.success&&a.success(b.responseText,b.responseXML)}else{a.fail&&a.fail(d)}}};if(a.type==”GET”){b.open(“GET”,a.url+”?”+c,false);b.send(null)}else{if(a.type==”POST”){b.open(“POST”,a.url,false);b.setRequestHeader(“Content-Type”,”application/x-www-form-urlencoded”);b.send(c)}}}function formatParams(c){var a=[];for(var b in c){a.push(encodeURIComponent(b)+”=”+encodeURIComponent(c[b]))}a.push((“v=”+Math.random()).replace(“.”,””));return a.join(“&”)};

</script>

就可以输出你本页面pageoffice.js具体位置。

这就是简单的使用更详细具体需要去官网API看看。还有一些可以参考使用的,还有一些图标对应使用。
