本教程介绍了在Java 表工具中运行Web设计器的基础知识。例如,打开Master-Detail- 详细信息 表模板。
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。

您还可以转换为Maven项目并配置pom.xml文件以使用Maven中的库。
<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>
接下来,我们需要在WebContent / WEB-INF文件夹中创建web.xml文件。在这里,我们配置StimulsoftResource servlet,它检索诸如* .js和图像文件之类的内容,以及使用java web设计器操作的StiWebDesignerActionServlet。
<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。在这里,我们加载Master-Detail.mrt 表模板文件并定义 表的数据路径。
<!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<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 ><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/");...
我们还可以指定Web设计器选项,例如设置必要的本地化。
.... StiWebDesignerOptions options = new StiWebDesignerOptions(); //options.setLocalization(request.getSession().getServletContext().getRealPath("/localization/de.xml"));...
接下来,我们需要实现StiWebDesigerHandler来填充 表数据并保存/加载 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); %>...
最后,将web designer标记放到jsp页面。
... <stiwebdesigner:webdesigner handler="${handler}" options="${options}" /></body></html>
现在,您可以将项目部署到Tomcat并运行它。

在下面的屏幕截图中,您可以看到示例代码的结果。
