使用jasperreports制作报表（导出pdf excel html）

最近项目需要制作报表类操作，所以在网上查了查资料找了找朋友帮我整了整，现在已经能跟顺利跑起来了，所以将这些东东写成文档，以备忘记。

首先需要下载 ireport ，这个是进行报表设计的，如果不会使用，可以上网查查具体用法，等会我会贴上我自己做的一个简单的小例子。

需要下载的资源：

ireport http://jasperforge.org/plugins/project/project_home.php?group_id=83

JasperReport  http://jasperforge.org/plugins/project/project_home.php?group_id=102

如果需要支持中文还需要以下两个包：

iTextAsian http://nchc.dl.sourceforge.net/sourceforge/itext/iTextAsian.jar

iText  http://nchc.dl.sourceforge.net/sourceforge/itext/iText-2.1.5.jar 

另外在发布工程的时候可能会提示缺少以下几个包：

commons-beanutils http://labs.xiaonei.com/apache-mirror/commons/beanutils/binaries/commons-beanutils-1.8.0-bin.zip

commons-digester http://apache.mirror.phpchina.com/commons/digester/binaries/commons-digester-2.0-bin.zip

commons-collections http://apache.freelamp.com/commons/collections/binaries/commons-collections-3.2.1-bin.zip

poi http://apache.mirror.phpchina.com/poi/release/bin/

commons-ogging http://commons.apache.org/downloads/download_logging.cgi

上述提到的包均需要拷贝到工程当中。

 

这样子基本上我们需要的包就算完整了，然后就是我们jsp页面了，我的所有导出数据都是通过这个jsp页面来实现的。

 这个是公共的报表生成模板，有了它一切报表都可能通过他生成了。

下一步就是报表的设计了，设计的时候我们要用ireport工具了，说实在他的功能还是很强大的，我自己做了一个简单的小例子，用的是我们的数据库，你们只需要简单修改成你们的数据库，就很容易实现了。

 数据库端使用的是sqlserver，大家可以根据自己需求自行配置。

另附简单demo一份。
