jsf和jsp

在此示例中，我將展示如何將DynamicReport和JasperReports與Servlet和CDI集成。

工具：

• TIBCO Jaspersoft Studio-6.0.4。最終版
• Eclipse Luna服務(wù)版本2（4.4.2）。
• WildFly 8.x應(yīng)用程序服務(wù)器。

這是Eclipse上項(xiàng)目層次結(jié)構(gòu)的屏幕截圖。

pom.xml文件包含Servlets + JSF + CDI + DynamicReports所需的依賴項(xiàng)。 <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>

使用TIBCO Jaspersoft Studio創(chuàng)建一個(gè)簡(jiǎn)單的JRXML模板，其中包含一個(gè)圖像，該圖像隨后將作為參數(shù)從DynamicReportsManagedBean動(dòng)態(tài)傳遞到DynamicReports。 <?xml version="1.0" encoding="UTF-8"?> <!-- Created with

創(chuàng)建一個(gè)Item類，它將成為包含要綁定到JRXML模板字段的數(shù)據(jù)的模型對(duì)象。 另外，我創(chuàng)建了一個(gè)InvoiceDetails類，該類具有將綁定到JRXML模板參數(shù)的數(shù)據(jù)。 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;} }

DynamicReportsManagedBean將負(fù)責(zé)準(zhǔn)備參數(shù)映射和包含將綁定到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;} }

CDI使我們能夠?qū)ynamicReportsManagedBean的實(shí)例注入到DynamicReportsServlet。 Servlet將處理響應(yīng)輸出流，該輸出將呈現(xiàn)從模板的DynamicReports創(chuàng)建的輸出流。 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;} }

在將servlet添加到web.xml中時(shí)，我更喜歡老派。 <?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>

index.xhtml包含一個(gè)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>

通過運(yùn)行示例的最終輸出。
