5.3. JRXML 报表示例
该示例也是基于示例 Library 应用程序,源代码可在 GitHub 上获取。
首先,在 CUBA Studio 中打开 Project Properties 编辑器:点击 CUBA → Project Properties 主菜单项。在页面上的 App components 列表中添加 reports 应用程序组件。然后启动应用。
打开 Reports → Reports 界面,然后单击 Import 按钮导入报表。在项目根目录中选择 Reports.zip。在表格中将显示两个报表,其中一个报表显示每个图书类目中可用的书籍。这个报表显示选中的类目下的图书出版物列表;默认输出格式为 XLS。我们为此报表创建新的 JasperReports 模板。
-
报表带区:
-
Header 带区 - 报表标题。它是包含 Groovy 脚本的数据集,该脚本输出报表外部参数值:
[['library_department_name' : params['library_department'].name]]
-
Data 带区通过运行以下 Groovy 脚本输出指定类目下的实例列表,这个类目根据传递的参数确定:
import com.haulmont.cuba.core.global.AppBeans def persistence = AppBeans.get('cuba_Persistence') def tx = persistence.createTransaction() try { def result = [] def em = persistence.getEntityManager() def ltList = em.createQuery('select lt from library$LiteratureType lt').getResultList() ltList.each { lt -> def count = em.createQuery(''' select count(bi) from library$BookInstance bi where bi.libraryDepartment = ?1 and bi.bookPublication.book.literatureType = ?2 ''') .setParameter(1, params['library_department']) .setParameter(2, lt) .getSingleResult() def refCount = em.createQuery(''' select count(bi) from library$BookInstance bi where bi.libraryDepartment = ?1 and bi.bookPublication.book.literatureType = ?2 and bi.isReference = true''') .setParameter(1, params['library_department']) .setParameter(2, lt) .getSingleResult() result.add(['literature_type_name': lt.name, 'books_instances_amount': count, 'reference_books_instances_amount': refCount]) } return result } finally { tx.end() }
此查询使用外部报表参数 -
library_department
。这个参数是 Entity 类型,但可以直接将其与实体标识符字段进行比较,类型转换会自动完成。
-
-
报表参数.
Parameters and Formats 标签页包含一个声明的报表外部参数 - Department:
运行报表时,用户必须输入此参数。部门是通过应用程序中的
library$LibraryDepartment.lookup
界面选择的。 -
报表模板。
Templates 标签页包含一个定义好的 XLS 模板,从
BookAvailability.xls
加载。使用以下内容创建新的 JRXML 文件:

这个模板中的表格绑定到子数据集(subDataset)。
title
元素直接使用 Header 区数据。可以在 JasperReports 可视化设计器中打开模板文件来查看报表布局。将新模板上传到应用程序,选择任何一种输出类型,并将其设置为默认值:
运行一下报表以确定报表定义正确:
