jaspereport学习资料
1）定制报表格式。
有二种方式，一种就是写jrxml文件，其实就是xml文件，只不过是后缀名不一样罢了。另一种方式更直接，就是生成一个JasperDesign类的实例，在japsperDesign中自己定义模板。jrxml文件也是通过一个JRXmlLoad加载过来，转成JasperDesign类的实例。也就是说写jrxml文件还需要进行解析，加载。现实中我们使用的报表一般格式比较固定，因而可以通过先使用iReport工具生成模板，再加载解析的方式。这种方式简单，而且可见性强。
2）填充数据。
在最新版（2007.4.30发布）的jasperReports1.3.3中，支持了很多的格式，包括了对于Hibernate的支持。填充数据对于我们经常使用的来说，一般是二种方式，一种方式是通过JDBC连接提供数据源，一种就是通过javaBean的集合提供数据源。当然还有web Service的xml文件提供的。我的建议是，如果你的程序中的统计直接使用Jdbc就可以完成，那么就使用jdbc数据源的方法，反之，使用 javaBean的集合是不错的选择，因为这样不会在意你的数据的来源，你也可以任意处理，比如说，要通过权限检查的数据才在报表中生成的话，就可以过滤到不符合权限的数据。
3）显示或打印。
显示，即将JasperReport生成的文件直接显示出来，打印所使用的方式其实就是生成文件，然后调用打印来对文件进行打印。
看起来是不是很简单，对，确实很简单。
笔者主要从事基于B/S模式的开发，相信大部分人的使用也是基于web进行使用。故笔者对于基于web的开发进行详细讲述。
1、工程环境配置。
将以下包加入WEB-INF/lib中。
commons-beanutils-1.7.jar;commons-collections-2.1.jar;commons-digester-1.7.jar;commons-logging-1.0.2.jar;commons-logging-api-1.0.2.jar;itext-1.3.1.jar;jasperreports-1.3.3.jar;jdt-compiler-3.1.1.jar;jxl-2.6.jar;png-encoder-1.5.jar;poi-2.0-final-20040126.jar
以上包是jasperReport必须。
2、iReport的安装
这个很简单，直接下一步就可以了。
3、使用iReport生成 .jasper文件
.jasper是经过编译的japserReport模板，即.jrxml编译后的。
对于iReport的使用网络上已经有了详细的中文的文档，具体可以下载附件查看。使用.jasper文件可以避免在系统中再进行编译，增加系统的压力。
4、数据填充
数据填充是相对于比较重要的一步，数据填充的目的是为了将数据填充进去，生成一个JapserPrint对象。笔者在之前已经阐述过，现在主要是基于关系型数据库（比较简单的，没有权限控制的），以及基于JavaBean Collection进行数据填充。进行数据填充的基本就是一定要实现JRDataSource，JRDataSource定义了二个方法，一个是指针移动的方法next()，另一个是取值的getFieldValue（）方法，用来取值填充。
对于关系型数据库，即直接利用数据库的表来生成报表的，只需要传入一个Java Connection即可。JasperReport已经有了个默认的实现的JRDataSource的接口了。对于Java Conncetion的获得，笔者建议使用工厂方法或者使用Spring方式来获得。可以参照笔者写的如下：

这样可以共用配置文件中的jdbc连接的相关参数。
对于其它的数据源，JavaBean Collection，笔者采用了一个抽象类，使用抽象类的目的，是为了使开发者尽可能不用直接接触jasperReport（此为笔者自己的方式，笔者是PM，为了考虑底下的人的开发）。以下为抽象类以及笔者提供的一个sample:

以上的例子应当很清楚的写明了如何生成数据源。
对于数据源的填充，笔者使用了二个类，分别用来对应使用Connction及JavaBean Collection进行填充。

有二种方式，一种就是写jrxml文件，其实就是xml文件，只不过是后缀名不一样罢了。另一种方式更直接，就是生成一个JasperDesign类的实例，在japsperDesign中自己定义模板。jrxml文件也是通过一个JRXmlLoad加载过来，转成JasperDesign类的实例。也就是说写jrxml文件还需要进行解析，加载。现实中我们使用的报表一般格式比较固定，因而可以通过先使用iReport工具生成模板，再加载解析的方式。这种方式简单，而且可见性强。
2）填充数据。
在最新版（2007.4.30发布）的jasperReports1.3.3中，支持了很多的格式，包括了对于Hibernate的支持。填充数据对于我们经常使用的来说，一般是二种方式，一种方式是通过JDBC连接提供数据源，一种就是通过javaBean的集合提供数据源。当然还有web Service的xml文件提供的。我的建议是，如果你的程序中的统计直接使用Jdbc就可以完成，那么就使用jdbc数据源的方法，反之，使用 javaBean的集合是不错的选择，因为这样不会在意你的数据的来源，你也可以任意处理，比如说，要通过权限检查的数据才在报表中生成的话，就可以过滤到不符合权限的数据。
3）显示或打印。
显示，即将JasperReport生成的文件直接显示出来，打印所使用的方式其实就是生成文件，然后调用打印来对文件进行打印。
看起来是不是很简单，对，确实很简单。
笔者主要从事基于B/S模式的开发，相信大部分人的使用也是基于web进行使用。故笔者对于基于web的开发进行详细讲述。
1、工程环境配置。
将以下包加入WEB-INF/lib中。
commons-beanutils-1.7.jar;commons-collections-2.1.jar;commons-digester-1.7.jar;commons-logging-1.0.2.jar;commons-logging-api-1.0.2.jar;itext-1.3.1.jar;jasperreports-1.3.3.jar;jdt-compiler-3.1.1.jar;jxl-2.6.jar;png-encoder-1.5.jar;poi-2.0-final-20040126.jar
以上包是jasperReport必须。
2、iReport的安装
这个很简单，直接下一步就可以了。
3、使用iReport生成 .jasper文件
.jasper是经过编译的japserReport模板，即.jrxml编译后的。
对于iReport的使用网络上已经有了详细的中文的文档，具体可以下载附件查看。使用.jasper文件可以避免在系统中再进行编译，增加系统的压力。
4、数据填充
数据填充是相对于比较重要的一步，数据填充的目的是为了将数据填充进去，生成一个JapserPrint对象。笔者在之前已经阐述过，现在主要是基于关系型数据库（比较简单的，没有权限控制的），以及基于JavaBean Collection进行数据填充。进行数据填充的基本就是一定要实现JRDataSource，JRDataSource定义了二个方法，一个是指针移动的方法next()，另一个是取值的getFieldValue（）方法，用来取值填充。
对于关系型数据库，即直接利用数据库的表来生成报表的，只需要传入一个Java Connection即可。JasperReport已经有了个默认的实现的JRDataSource的接口了。对于Java Conncetion的获得，笔者建议使用工厂方法或者使用Spring方式来获得。可以参照笔者写的如下：

对于其它的数据源，JavaBean Collection，笔者采用了一个抽象类，使用抽象类的目的，是为了使开发者尽可能不用直接接触jasperReport（此为笔者自己的方式，笔者是PM，为了考虑底下的人的开发）。以下为抽象类以及笔者提供的一个sample:

以上的例子应当很清楚的写明了如何生成数据源。
对于数据源的填充，笔者使用了二个类，分别用来对应使用Connction及JavaBean Collection进行填充。
