在此示例中，我将展示如何将DynamicReport和JasperReports与Servlet和CDI集成。

工具：

• TIBCO Jaspersoft Studio-6.0.4。最终版
• Eclipse Luna服务版本2（4.4.2）。
• WildFly 8.x应用程序服务器。

这是Eclipse上项目层次结构的屏幕截图。

1. pom.xml文件包含Servlets + JSF + CDI + DynamicReports所需的依赖项。

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.ithinkisink</groupId><artifactId>DynamicReportsWithJSFServletsAndCDI</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>DynamicReportsWithJSFServletsAndCDI Maven Webapp</name><dependencies><dependency><groupId>javax.inject</groupId><artifactId>javax.inject</artifactId><version>1</version><scope>provided</scope></dependency><dependency><groupId>javax.faces</groupId><artifactId>jsf-api</artifactId><version>2.1</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.1.0</version><scope>provided</scope></dependency><dependency><groupId>javax.enterprise</groupId><artifactId>cdi-api</artifactId><version>1.0</version><scope>provided</scope></dependency><dependency><groupId>net.sourceforge.dynamicreports</groupId><artifactId>dynamicreports-core</artifactId><version>4.0.0</version></dependency></dependencies><build><finalName>DynamicReportsWithJSFServletsAndCDI</finalName><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><source>1.7</source><target>1.7</target></configuration></plugin></plugins></build>
   </project>

2. 使用TIBCO Jaspersoft Studio创建一个简单的JRXML模板，其中包含一个图像，该图像随后将作为参数从DynamicReportsManagedBean动态传递到DynamicReports。

3. 创建一个Item类，它将作为模型对象，其中包含要绑定到JRXML模板字段的数据。 另外，我创建了一个InvoiceDetails类，该类具有将绑定到JRXML模板参数的数据。

   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将负责准备参数列表和包含将绑定到JRXML字段的Lis​​t <Item>的JRBeanCollectionDataSource。

   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;@PostConstructpublic 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 getterspublic 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使我们能够将DynamicReportsManagedBean的实例注入到DynamicReportsServlet。 Servlet将处理响应输出流，该响应输出流将显示从模板的DynamicReports创建的输出流。

   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;@Injectprivate DynamicReportsManagedBean dynamicReportsManagedBean;@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {resp.setContentType("application/pdf");OutputStream out = resp.getOutputStream();out = dynamicReportsManagedBean.getOS(getServletContext(), out);out.close();}@Overrideprotected 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. 在将servlet添加到web.xml中时，我更喜欢老派。

   <?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包含一个指向servlet的<iframe>。

   <!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. 通过运行示例的最终输出。
