【Stimulsoft Reports Java教程】執行Java Web Designer
阿新 • • 發佈:2018-11-20
本教程介紹了在Java報表工具中執行Web設計器的基礎知識。例如,開啟Master-Detail- 詳細資訊報表模板。
首先,我們需要建立動態Web專案。
然後將Stimulsoft Java Libs新增到專案中。
您還可以轉換為Maven專案並配置pom.xml檔案以使用Maven中的庫。
<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/xsd/maven-4.0.0.xsd“ > <modelVersion> 4.0.0 < / modelVersion> <groupId> webdesigner < / groupId > <artifactId> webdesigner < / artifactId> <version> 0.0.1-SNAPSHOT < / version> <packaging> war </ packaging> <build> <sourceDirectory> src < / sourceDirectory> <plugins> <plugin> <artifactId> maven-compiler-plugin < / artifactId> <version> 3.5.1 < / version> <configuration> <source> 1.6 < / source> <target> 1.6 < / target> < / configuration> < / plugin> < / plugins> < / build> <dependencies> <dependency> <groupId> com.stimulsoft </ groupId> <artifactId> stimulsoft-reports-libs < / artifactId> <version> 2017.1.1 < / version> < / dependency> < / dependencies> < / project>
接下來,我們需要在WebContent / WEB-INF資料夾中建立web.xml檔案。在這裡,我們配置StimulsoftResource servlet,它檢索諸如* .js和影象檔案之類的內容,以及使用java web設計器操作的StiWebDesignerActionServlet。
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/webapp_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>stimulsoft_webdesigner</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>StimulsoftResource</servlet-name> <servlet-class>com.stimulsoft.web.servlet.StiWebResourceServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>StimulsoftResource</servlet-name> <url-pattern>/stimulsoft_web_resource/*</url-pattern> </servlet-mapping> <servlet> <servlet-name>StimulsoftDesignerAction</servlet-name> <servlet-class>com.stimulsoft.webdesigner.servlet.StiWebDesignerActionServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>StimulsoftDesignerAction</servlet-name> <url-pattern>/stimulsoft_webdesigner_action</url-pattern> </servlet-mapping> </web-app>
在下一步中,我們需要在WebContent資料夾中建立index.jsp頁面。在這裡,我們載入Master-Detail.mrt報表模板檔案並定義報表的資料路徑。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <%@page import=";java.io.FileOutputStream"%> <%@page import=";java.io.FileInputStream"%> <%@page import=";com.stimulsoft.report.utils.data.StiDataColumnsUtil"%> <%@page import=";com.stimulsoft.report.dictionary.StiDataColumnsCollection"%> <%@page import=";com.stimulsoft.report.dictionary.StiDataColumn"%> <%@page import=";com.stimulsoft.report.utils.data.StiSqlField"%> <%@page import=";com.stimulsoft.report.dictionary.dataSources.StiDataTableSource"%> <%@page import=";com.stimulsoft.report.utils.data.StiXmlTable"%> <%@page import=";com.stimulsoft.report.utils.data.StiXmlTableFildsRequest"%> <%@page import=";com.stimulsoft.webdesigner.StiWebDesigerHandler"%> <%@page import=";com.stimulsoft.webdesigner.StiWebDesignerOptions"%> <%@page<br< a=""> /> import="com.stimulsoft.report.dictionary.databases.StiXmlDatabase"%> <%@page import=";java.io.File"%> <%@page import=";com.stimulsoft.report.StiSerializeManager"%> <%@page import=";com.stimulsoft.report.StiReport"%> <%@page language=";java" contentType="text/html; charset=utf-8" pageEncoding="UTF-8"%> <%@taglib uri=";http://stimulsoft.com/webdesigner" prefix="stiwebdesigner"%> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Stimulsoft Webdesigner for Java</title> <style type="text/css"> </style> </head> <body> <% final String reportPath = request.getSession().getServletContext().getRealPath("/reports/Master-Detail.mrt"); final String xmlPath = request.getSession().getServletContext().getRealPath("/data/Demo.xml"); final String xsdPath = request.getSession().getServletContext().getRealPath("/data/Demo.xsd"); final String savePath = request.getSession().getServletContext().getRealPath("/save/"); ...
我們還可以指定Web設計器選項,例如設定必要的本地化。
.... StiWebDesignerOptions options = new StiWebDesignerOptions(); //options.setLocalization(request.getSession().getServletContext().getRealPath("/localization/de.xml")); ...
接下來,我們需要實現StiWebDesigerHandler來填充報表資料並儲存/載入報表模板。
.... StiWebDesigerHandler handler = new StiWebDesigerHandler(){ //Occurred on loading webdesinger. Must return edited StiReport public StiReport getEditedReport(HttpServletRequest request){ try{ StiReport report = StiSerializeManager.deserializeReport(new File(reportPath)); report.getDictionary().getDatabases().add(new StiXmlDatabase("Demo", xsdPath, xmlPath)); return report; } catch (Exception e){ e.printStackTrace(); } return null; } //Occurred on opening StiReport. Method intended for populate report data. public void onOpenReportTemplate(StiReport report, HttpServletRequest request){ report.getDictionary().getDatabases().add(new StiXmlDatabase("Demo", xsdPath, xmlPath)); } //Occurred on new StiReport. Method intended for populate report data. public void onNewReportTemplate(StiReport report, HttpServletRequest request){ report.getDictionary().getDatabases().add(new StiXmlDatabase("Demo", xsdPath, xmlPath)); try{ StiXmlTableFildsRequest tables = StiDataColumnsUtil.parceXSDSchema(new FileInputStream(xsdPath)); for (StiXmlTable table : tables.getTables()){ StiDataTableSource tableSource = new StiDataTableSource( "Demo." + table.getName(), table.getName(), table.getName()); tableSource.setColumns(new StiDataColumnsCollection()); for (StiSqlField field : table.getColumns()){ StiDataColumn column = new StiDataColumn( field.getName(), field.getName(), field.getSystemType()); tableSource.getColumns().add(column); } tableSource.setDictionary(report.getDictionary()); report.getDictionary().getDataSources().add(tableSource); } } catch (Exception e){ e.printStackTrace(); } } //Occurred on save StiReport. Method must implement saving StiReport public void onSaveReportTemplate(StiReport report, StiRequestParams requestParams, HttpServletRequest request) { try { FileOutputStream fos = new FileOutputStream(savePath + requestParams.designer.fileName); if (requestParams.designer.password != null) { StiSerializeManager.serializeReport(report, fos, requestParams.designer.password); } else { StiSerializeManager.serializeReport(report, fos, true); } fos.close(); } catch (Exception e) { e.printStackTrace(); } } }; pageContext.setAttribute("handler", handler); pageContext.setAttribute("options", options); %> ...
最後,將web designer標記放到jsp頁面。
... <stiwebdesigner:webdesigner handler="${handler}" options="${options}" /> </body> </html>
現在,您可以將專案部署到Tomcat並執行它。
在下面的螢幕截圖中,您可以看到示例程式碼的結果。
