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

首先,我们需要创建动态Web项目。

Stimulsoft

然后将Stimulsoft Java Libs添加到项目中。

Stimulsoft

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 = “//maven.apache.org/POM/4.0.0”
         xmlns:xsi = “//www.w3.org/2001/XMLSchema-instance”
         xsi:schemaLocation = “http:/ /maven.apache.org/POM/4.0.0 //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。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
        xmlns="//java.sun.com/xml/ns/javaee" 
        xmlns:web="//java.sun.com/xml/ns/javaee/webapp_2_5.xsd" 
        xsi:schemaLocation="//java.sun.com/xml/ns/javaee //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报表模板文件并定义报表的数据路径。

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "//www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<%@page import=";java.io.FileOutputStream"%>
<%@page import=";java.io.FileInputStream"%>

<%@page language=";java" contentType="text/html; charset=utf-8" pageEncoding="UTF-8"%>
<%@taglib uri=";//stimulsoft.com/webdesigner" prefix="stiwebdesigner"%>
<html xmlns="//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来填充报表数据并保存/加载报表模板。

....
        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。
