DynamicReports и JasperReports с JSF, сервлетом и CDI

В этом примере я покажу, как интегрировать DynamicReport и JasperReports с сервлетом и CDI.

Инструменты:

• TIBCO Jaspersoft Studio-6.0.4. Финал.
• Eclipse Luna Service Release 2 (4.4.2).
• Сервер приложений WildFly 8.x.

Это скриншот из иерархии проектов в Eclipse.

1. Файл pom.xml содержит необходимые зависимости для сервлетов + JSF + CDI + DynamicReports.

2. Создание простого шаблона JRXML с использованием TIBCO Jaspersoft Studio, содержащего изображение, которое будет динамически передавать его путь в качестве параметра из DynamicReportsManagedBean в DynamicReports позже.

3. Создание класса Item, который будет объектом модели, содержащим данные, которые будут связаны с полями шаблона JRXML. Также я создал класс InvoiceDetails, в котором будут данные, которые будут связаны с параметрами шаблона JRXML.

   01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

   package com.ithinkisink.model;   /**  *  * @author Belal  *  */ public class Item {    private String itemNo;  private String description;  private double unitCost;  private int quantity;     public Item(String itemNo, String description, double unitCost, int quantity) {   super();   this.itemNo = itemNo;   this.description = description;   this.unitCost = unitCost;   this.quantity = quantity;  }    public String getItemNo() {   return itemNo;  }    public void setItemNo(String itemNo) {   this.itemNo = itemNo;  }    public String getDescription() {   return description;  }    public void setDescription(String description) {   this.description = description;  }    public double getUnitCost() {   return unitCost;  }    public void setUnitCost(double unitCost) {   this.unitCost = unitCost;  }    public int getQuantity() {   return quantity;  }    public void setQuantity(int quantity) {   this.quantity = quantity;  } }

4. DynamicReportsManagedBean будет отвечать за подготовку карты параметров и источника JRBeanCollectionDataSource, содержащего List <Item>, который будет связан с полями JRXML.

   001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 071 072 073 074 075 076 077 078 079 080 081 082 083 084 085 086 087 088 089 090 091 092 093 094 095 096 097 098 099 100 101

   package com.ithinkisink.managedbean;   import static net.sf.dynamicreports.report.builder.DynamicReports.report;   import java.io.InputStream; import java.io.OutputStream; import java.io.Serializable; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import java.util.Map;   import javax.annotation.PostConstruct; import javax.enterprise.context.SessionScoped; import javax.inject.Named; import javax.servlet.ServletContext;   import net.sf.dynamicreports.report.exception.DRException; import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;   import com.ithinkisink.model.InvoiceDetails; import com.ithinkisink.model.Item;   /**  *  * @author Belal  *  */ @Named @SessionScoped public class DynamicReportsManagedBean implements Serializable {    private static final long serialVersionUID = -1;    private String invoiceName;  private JRBeanCollectionDataSource beanCollectionDataSource;  private Map<String, Object> parameters;    @PostConstruct  public void init() {   invoiceName="Invoice.jrxml";       List<Item> itemList = new ArrayList<>(Arrays.asList(     new Item("01", "Item 01 description", 1.1, 1),     new Item("02", "Item 02 description", 2.2, 2),     new Item("03", "Item 03 description", 3.3, 3)));   beanCollectionDataSource = new JRBeanCollectionDataSource(itemList);       parameters = (new InvoiceDetails("INV#01", "Billing Company", "Billing Company Add",     "Billing Company State 1", "Billing Company State 2",     "Shipping Name", "Shipping Address", "Shipping State 1", "Shipping State 2", 1000)).toMap();  }     /**   * Preparing an output stream of the generated PDF invoice.   *   * @return   */  public OutputStream getOS(ServletContext context, OutputStream outputStream) {     parameters.put("IMAGE_PATH", context.getRealPath("/jasper/invoices"));     InputStream is = context.getResourceAsStream("/jasper/invoices/" + invoiceName);     try {    report().setTemplateDesign(is)      .setDataSource(beanCollectionDataSource)      .setParameters(parameters).toPdf(outputStream);   } catch (DRException e) {    e.printStackTrace();   }     return outputStream;  }    // setters and getters  public String getInvoiceName() {   return invoiceName;  }    public void setInvoiceName(String invoiceName) {   this.invoiceName = invoiceName;  }    public JRBeanCollectionDataSource getBeanCollectionDataSource() {   return beanCollectionDataSource;  }    public void setBeanCollectionDataSource(    JRBeanCollectionDataSource beanCollectionDataSource) {   this.beanCollectionDataSource = beanCollectionDataSource;  }    public void setParameters(Map<String, Object> parameters) {   this.parameters = parameters;  }    public Map<String, Object> getParameters() {   return parameters;  } }

5. CDI позволяет нам внедрить экземпляр DynamicReportsManagedBean в DynamicReportsServlet. Сервлет будет обрабатывать поток вывода ответа, который будет представлять созданный поток вывода из DynamicReports шаблона.

   01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

   package com.ithinkisink.servlet;   import java.io.IOException; import java.io.OutputStream;   import javax.inject.Inject; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;   import com.ithinkisink.managedbean.DynamicReportsManagedBean;   /**  *  * @author Belal  *  */ public class DynamicReportsServlet extends HttpServlet {  private static final long serialVersionUID = 1L;    @Inject  private DynamicReportsManagedBean dynamicReportsManagedBean;     @Override  protected void doGet(HttpServletRequest req, HttpServletResponse resp)    throws ServletException, IOException {   resp.setContentType("application/pdf");   OutputStream out = resp.getOutputStream();   out = dynamicReportsManagedBean.getOS(getServletContext(), out);   out.close();  }     @Override  protected void doPost(HttpServletRequest req, HttpServletResponse resp)    throws ServletException, IOException {   super.doPost(req, resp);   this.doGet(req, resp);  }     public void setDynamicReportsManagedBean(    DynamicReportsManagedBean dynamicReportsManagedBean) {   this.dynamicReportsManagedBean = dynamicReportsManagedBean;  }     public DynamicReportsManagedBean getDynamicReportsManagedBean() {   return dynamicReportsManagedBean;  } }

6. Я предпочитаю старую школу при добавлении сервлета в web.xml.

   01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22

   <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">    <display-name>DynamicReportsWithJSFServletsAndCDI Maven Webapp</display-name>    <servlet>   <description></description>   <display-name>DynamicReportsServlet</display-name>   <servlet-name>DynamicReportsServlet</servlet-name>   <servlet-class>com.ithinkisink.servlet.DynamicReportsServlet</servlet-class>  </servlet>  <servlet-mapping>   <servlet-name>DynamicReportsServlet</servlet-name>   <url-pattern>/*</url-pattern>  </servlet-mapping>     <welcome-file-list>   <welcome-file>/index.xhtml</welcome-file>  </welcome-file-list> </web-app>

7. Index.xhtml содержит <iframe>, который указывает на сервлет.

   01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16

   <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"  xmlns:h="http://java.sun.com/jsf/html">   <h:head>  <title>DynamicReports with Servlets, JSF and CDI</title> </h:head>   <h:body>  <h:form>   <iframe name="receipt" height="600" id="theIFrame" width="100%"    src="http://localhost:8080/DynamicReportsWithJSFServletsAndCDI" />  </h:form> </h:body>   </html>

8. Окончательный вывод, запустив пример.
