java漫画阅读器代码 java漫画阅读器代码怎么用
Java漫画下载
如是智能机而屏幕够大的话， 可以使用pdf阅读器， 如是非智能且支持java功能的话。就下个umd阅读器。 实在不行就下jpg格式的图片吧。放在大屏幕的播放器里，一样可以看的很爽的。。。。。。

大神问个问题，在JSP页面中用Java怎么实现网上看漫画的那种功能
基本架构是建立个文件夹，一本漫画一个，然后把图片按照1，2，3.jpg的方法编辑好。然后用a href="read.jsp?type=%****%page=%****%"/a这个是写在jsp里的，定义几个变量，然后用这个方法传参数给自己，就能跳到你指定的图片。图片用img src="******%****%.jpg",就是把你输入的值带入，出来是第几个jpg的图，很简单的，一个页面就搞定了，不用连接数据库什么的，也没有什么js````
