图表生成器Stimulsoft Reports.Java示例:运行 Java 页设计器

首先,我们需要创建动态 Web 项目。

然后将 Stimulsoft Java Libs 添加到项目中。

也可以转换为 Maven 项目并配置pom.xml文件以使用来自Maven 的库:

<project 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>

接下来,我们需要在“WebContent/WEB-INF”文件夹中创建“web.xml”文件。这里我们配置了StimulsoftResourceservlet 来检索诸如 *.js 和图像文件等内容,以及StiWebDesignerActionServlet与 java web 设计器一起操作的servlet :

<ml version="1.0" encoding="UTF-8"gt;<web-app xmlns_xsi="http://www.w3.org/2001/XMLSchema-instance"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,我们需要在“WebContent”文件夹中创建“index.jsp”页面。这里我们加载“Master-Detail.mrt” 告模板文件并定义 告的数据路径:

<!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 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 ><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/");...

接下来我们需要实现StiWebDesigerHandler用于填充 告数据并保存/加载 告模板:

...StiWebDesignerOptions options = new StiWebDesignerOptions();//options.setLocalization(request.getSession().getServletContext().getRealPath("/localization/de.xml"));...

我们也可以指定 页设计器选项,例如设置必要的本地化:

...StiWebDesigerHandler handler = new StiWebDesigerHandler() {// Occurred on loading webdesinger. Must return edited StiReportpublic 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 StiReportpublic 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);%>...

最后,将 页设计器标签放到jsp页面中:

...<stiwebdesigner:webdesigner handler="${handler}" options="${options}" /></body></html>

现在您可以将项目部署到 Tomcat 并运行它。
