Spring MVC配置(三)

以下是本人对Spring MVC View层AbstractPdfView的一个实现及使用:

1.AbstractPdfView的实现类:

package com.sunfairs.northwind.servlet; import java.awt.Color; import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.view.document.AbstractPdfView; import com.lowagie.text.Document; import com.lowagie.text.Font; import com.lowagie.text.FontFactory; import com.lowagie.text.Paragraph; import com.lowagie.text.Table; import com.lowagie.text.pdf.PdfWriter; public class ReportXlsViewResolver extends AbstractPdfView { @Override protected void buildPdfDocument(Map map, Document document, PdfWriter writer, HttpServletRequest request, HttpServletResponse response) throws Exception { String header = (String) map.get("header"); Paragraph headerParagraph = new Paragraph(header); headerParagraph.setFont(FontFactory.getFont(FontFactory.HELVETICA, 16, Font.BOLD, new Color(255, 0, 0))); document.add(headerParagraph); Table content = (Table) map.get("content"); document.add(content); String copyRight = (String) map.get("copyRight"); Paragraph copyRightParagraph = new Paragraph(copyRight); document.add(copyRightParagraph); } }

2.AbstractController的实现:

package com.sunfairs.northwind.servlet; import java.awt.Color; import java.util.HashMap; import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.log4j.Logger; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; import com.lowagie.text.Cell; import com.lowagie.text.Phrase; import com.lowagie.text.Table; public class PdfViewController extends AbstractController { private static final Logger logger = Logger.getLogger(PdfViewController.class); private String viewName; public String getViewName() { return viewName; } public void setViewName(String viewName) { this.viewName = viewName; } @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { Map map = new HashMap(); map.put("header", "PDF Viewer"); Table table = new Table(5,4); table.setAlignment("center"); table.setBackgroundColor(Color.LIGHT_GRAY); table.setBorder(1); table.setBorderColor(Color.YELLOW); table.setSpacing(0); table.setPadding(0); table.addCell(new Phrase("Name")); table.addCell(new Phrase("Age")); table.addCell(new Phrase("Total purchase")); table.addCell(new Phrase("Email")); table.addCell(new Phrase("Date")); table.addCell(new Phrase("Peter")); table.addCell(new Phrase("28")); table.addCell(new Phrase("$9.99")); table.addCell(new Phrase("peter.parker@gmail.com")); table.addCell(new Phrase("Jul 6, 2006 8:14 AM")); table.addCell(new Phrase("John")); table.addCell(new Phrase("32")); table.addCell(new Phrase("$19.99")); table.addCell(new Phrase("john.doe@gmail.com")); table.addCell(new Phrase("Dec 10, 2002 5:14 AM")); map.put("content", table); map.put("copyRight", "All rights reserve©boboo_2000_0"); return new ModelAndView(this.getViewName(),map); } }

3.web.xml配置:

<servlet> <servlet-name>viewServlet</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>viewServlet</servlet-name> <url-pattern>*.po</url-pattern> </servlet-mapping>

4.viewServlet-servlet.xml的配置:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" > <beans> <bean id="viewResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver"/> <bean id="servletHandlerAdapter" class="org.springframework.web.servlet.handler.SimpleServletHandlerAdapter"/> <bean id="controllerHandlerAdapter" class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> <bean id="beanMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="excel.po">pdfViewController</prop> </props> </property> </bean> <bean id="reportXlsView" class="com.sunfairs.northwind.servlet.ReportXlsViewResolver"/> <bean id="pdfViewController" class="com.sunfairs.northwind.servlet.PdfViewController"> <property name="viewName"> <value>reportXlsView</value> </property> </bean> </beans>
