關於使用java或者前段jsp打開本地PDF文件

第一種比較簡單的方法，可是該方法IE沒法打開javascript

function  _doOption(value,row,index){
	var peruuid=row.GOODS_REG_UUID;//有值說明已經審覈
	return "<a href='javascript:void(0);' onclick='_ApproveDig(\""+peruuid+"\")' class='easyui-linkbutton' data-options='iconCls:\"icon-remove\",plain:true'>文書查看</a>";
}


function _ApproveDig(peruuid){
	var type='2';
	//window.location.href="checkEvidence_OpenPdf.do?uuid="+peruuid+'&type='+type;
	var url="checkEvidence_OpenPdf.do?uuid="+peruuid+'&type='+type;
	window.open (url);
}


public String OpenPdf() throws Exception{
		String uuid=request.getParameter("uuid");
		String doc=checkEvidenceService.queryURLByid(uuid);
		String pf ="C:"; 
		String filePath=pf+doc;
		request.setAttribute("filePath", filePath);
		return "pdfview";
	//	String url1="C:/home/monopy/document/1e3edcd0-6aef-4a84-9218-9cd730394606/阿里巴巴Java開發手冊.pdf";  測試用
		response.setContentType("application/pdf");
		FileInputStream in = new FileInputStream(new File(filePath));
		OutputStream out = response.getOutputStream();
        byte[] b = new byte[512];
        while ((in.read(b)) != -1) {
            out.write(b);
        }
        out.flush();
        in.close();
        out.close();
	}

2.第二種方法，稍微有點複雜，這個方法IE是能夠打開PDF文件的html

function  _doOption(value,row,index){
	var peruuid=row.GOODS_REG_UUID;//有值說明已經審覈
	return "<a href='javascript:void(0);' onclick='_ApproveDig(\""+peruuid+"\")' class='easyui-linkbutton' data-options='iconCls:\"icon-remove\",plain:true'>文書查看</a>";
}
AJAX的請求只是去後臺拿完整的url,無其餘意圖，而後使用window.location.href去訪問jsp

function _ApproveDig(peruuid){
	$.ajax({
		cache: true,
        type: "POST",
        url:context+'/check/checkEvidence_OpenPdf.do',
        data:{uuid:peruuid},
        async: false,
        dataType: 'json',
		async : true,
		success : function(data){
			var url=data.url;
		    var url1 =encodeURI(encodeURI(context+'/include/ntko/pdfView.jsp?filePath='+url,"utf-8"),"utf-8");
			//var url1=context+'/include/ntko/pdfView.jsp?filePath='+url;
			window.location.href=url1;
		}
	});
}

這是預覽頁面，須要插件 ntko,須要插件的能夠私我，這個上傳太麻煩 ntkooledocall.cab，OfficeControl.cab，須要對url進行再次轉碼，不然會中文亂碼java
