5.如何使用報表設計器創建示例頁面？
用報表設計器創建一個簡單的頁面。為此，請將以下庫放入WebContent \ WEB-INF \ lib \目錄中：stimulsoft.lib.jar，stimulsoft.reports-base.jar，stimulsoft.reports-report.jar，stimulsoft.reports-flex.jar， stimulsoft.reports-web.jar。結果，可以看到以下內容（下圖）：
圖8.將庫放置在項目中
接下來，打開web.xml進行編輯，它應該類似于清單2：
<?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"
id="WebApp_ID" version="2.5">
<display-name>sti_webviewer</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- configuration, this parameter indicates the main application directory -->
<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>StimulsoftAction</servlet-name>
<servlet-class>com.stimulsoft.webviewer.servlet.StiWebViewerActionServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>StimulsoftAction</servlet-name>
<url-pattern>/stimulsoft_webviewer_action</url-pattern>
</servlet-mapping>
</web-app>
清單2. web.xml的內容
其余的web.xml塊保持不變，它們定義了工作所需的servlet。然后，編輯index.jsp（請參見下面的代碼）：
<!DOCTYPEhtmlPUBLIC"-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib uri="http://stimulsoft.com/designer" prefix="stidesignerfx" %>
<%@ taglib uri="http://stimulsoft.com/viewer" prefix="stiviewerfx" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Stimulsoft Reports.Fx for Java</title>
</head>
<body>
<h1 align="center">My first report!</h1>
<stidesignerfx:iframe
width="100%" height="90%" align="middle"
styleClass="" frameborder="0" styleId=""
marginheight="4" marginwidth="10" name="stiviewer"
scrolling="no" style="" title="report"/>
</body>
</html>
清單3. index.jsp的內容
在JSP中添加taglib指令（清單4）。它們將與頁面上的自定義標簽一起使用。
<%@ taglib uri="http://stimulsoft.com/designer" prefix="stidesignerfx" %>
<%@ taglib uri="http://stimulsoft.com/viewer" prefix="stiviewerfx" %>
清單4.自定義Stimulsoft標簽
添加標簽<stidesignerfx：iframe />，它是html標簽iframe的類似物，并支持其所有屬性。作為應用程序部署的結果，請參見以下內容（圖9）：
6.您是否有自定義標簽的描述？
從清單5中可以看出，它分為兩個組件：DesignerFx和ViewerFx?？紤]一個DesignerFx組件。對于ViewerFx，其工作方式相同。
<stidesignerfx:link text="a link for jumping to the Designer"/>
<stidesignerfx:button value="a button for jumping to the Designer"/>
<stidesignerfx:frame title="analog of the html tag frame which contains a Designer"/>
<stidesignerfx:iframe title="analog of the html tag iframe which contains a Designer"/>
所有這些都是類似HTML標記的類似物，支持所有屬性。擴展了標準屬性列表，以顯示報告和設置報告變量。report =“ SimpleList.mrt”屬性將打開名稱為SimpleList.mrt的報告。報表中的變量可以通過兩種方式傳遞：
以以下格式將variableStr屬性的值設置為字符串：“ Variable1 = value1＆Variable2 = value2”。在這種情況下，將在報表中傳遞兩個具有value1的變量Variable1和具有value2的Variable2。例如，您需要編輯index.jsp文件以通過單擊按鈕打開名為MyFirstReport.mrt的報告，并且MyVar報告變量具有stidesignerfx值（清單6）。
<!DOCTYPEhtmlPUBLIC"-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ page contentType="text/html;charset=UTF-8" import="java.util.*" %>
<%@ taglib uri="http://stimulsoft.com/designer" prefix="stidesignerfx" %>
<%@ taglib uri="http://stimulsoft.com/viewer" prefix="stiviewerfx" %>
<html>
<head>
<title>Report</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<stidesignerfx:button value="Run the report designer" report="MyFirstReport.mrt" variableStr="MyVar=stidesignerfx" />
</html>
也可以將參數作為Map <string，string =>傳遞給報表。重新設計我們的網頁，如下所示（清單6）。在這種情況下，名稱為MyFirstReport.mrt的報表將被加載到報表中，并將兩個參數傳遞到該報表中。
<!DOCTYPEhtmlPUBLIC"-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ page contentType="text/html;charset=UTF-8" import="java.util.*" %>
<%@ taglib uri="http://stimulsoft.com/designer" prefix="stidesignerfx" %>
<%@ taglib uri="http://stimulsoft.com/viewer" prefix="stiviewerfx" %>
<html>
<head>
<title>Report</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<%
Map<String, String>variableMap= new HashMap<String, String>();
variableMap.put("Variable1", "var1");
variableMap.put("Variable2", "var2");
request.setAttribute("myMap", variableMap);
%>
<stidesignerfx:iframe report="MyFirstReport.mrt" variableMap="myMap"
width="100%" height="100%" align="right"
styleClass="" frameborder="0" styleId=""
marginheight="1" marginwidth="1" name="stidesignerfx"
scrolling="no" style="" title="report" />
</body>
</html>
此處的數據作為HashMap傳遞，此參數應設置為請求或會話，并將其存在的鍵作為variableMap屬性傳遞給標簽。不允許應用兩個屬性variableMap和variableStr。
7.如何覆蓋加載，保存和加載自定義數據的方法？
在運行之前，應先配置應用程序。為了進行配置，使用了web.xml中指定的
my.servlet.ApplicationInitializer類。
package my.servlet;
import java.io.IOException;
import java.util.Properties;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import my.actions.MyLoadAction;
import my.actions.MyLoadDataAction;
import my.actions.MyLocalizationAction;
import my.actions.MyMailAction;
import my.actions.MyRenderReportAction;
import my.actions.MySaveAction;
import com.stimulsoft.base.exception.StiException;
import com.stimulsoft.flex.StiFlexConfig;
/**
* Application initialization.
*/
public class ApplicationInitializer implements ServletContextListener {
@Override
public void contextInitialized(final ServletContextEvent event) {
try {
// configuration application
StiFlexConfig stiConfig = initConfigWithoutDir();
// ---------------------------------------------------------
// need to override the standard methods
// another comment
stiConfig.setLoadClass(MyLoadAction.class);
stiConfig.setSaveClass(MySaveAction.class);
stiConfig.setLoadDataClass(MyLoadDataAction.class);
stiConfig.setMailAction(MyMailAction.class);
stiConfig.setLocalizationAction(MyLocalizationAction.class);
stiConfig.setRenderReportAction(MyRenderReportAction.class);
// ---------------------------------------------------------
StiFlexConfig.init(stiConfig);
// set variable in servlet context attribute
// Map<String, String> myVariableMap = new HashMap<String, String>();
// myVariableMap.put("Variable1", "myVariableMap");
// event.getServletContext().setAttribute("myMap", myVariableMap);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void contextDestroyed(final ServletContextEvent event) {
// empty
}
public StiFlexConfig initConfigWithoutDir() throws StiException, IOException {
Properties properties = new Properties();
// load your own Properties;
// InputStream inStream = getClass().getResourceAsStream("RESOURCE_PATH");
// properties.load(inStream);
return new StiFlexConfig(properties);
}
}
將在其中定義帶有文件stimulsoft.properties的主應用程序目錄。為了保存或加載自己的報告，有必要在配置中指定這些類，就像指定可以從xml加載數據的類一樣。類如下：列出MyLoadAction.java
package my.actions;
import java.io.InputStream;
import com.stimulsoft.actions.LoadAction;
import com.stimulsoft.library.LoadFileReport;
public class MyLoadAction extends LoadAction {
@Override
public InputStream load(String repotrName) {
System.out.println("my load class" + repotrName);
return new LoadFileReport().getReport(repotrName);
}
}
package my.actions;
import com.stimulsoft.flex.StiSaveAction;
import com.stimulsoft.flex.utils.StiOperationResult;
import com.stimulsoft.flex.utils.StiSaveLoadFileReport;
public class MySaveAction extends StiSaveAction {
@Override
public StiOperationResult save(String report, String reportName, boolean newReportFlag) {
System.out.println("must override this method to specify your own save report");
return new StiSaveLoadFileReport().save(report, reportName, newReportFlag);
}
}
package my.actions;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
import com.stimulsoft.flex.StiLoadDataAction;
public class MyLoadDataAction extends StiLoadDataAction {
@Override
protected String getConnectionString() {
System.out.println("must override this method to specify your own connection string");
// return
// "Data Source=localhost\\SQLEXPRESS;Initial Catalog=Mybase;User ID=UserName; Password=Password;";
return super.getConnectionString();
}
@Override
protected String getUserName() {
System.out.println("must override this method to specify your own user name");
// return "UserName";
return super.getUserName();
}
@Override
protected String getPassword() {
System.out.println("must override this method to specify your own password");
// return "Password";
return super.getPassword();
}
@Override
protected String getQuery() {
System.out.println("my Query " + super.getQuery());
return super.getQuery();
}
@Override
public Connection getConnection() throws ClassNotFoundException, SQLException {
System.out.println("must override this method to specify your own connection");
boolean overrideByConnectionString = getConnectionString() != null
&& getConnectionString().equals("needOverride");
boolean overrideByDataSource = getDataSourceName() != null
&& getDataSourceName().equals("DataSourceOverride");
if (overrideByConnectionString || overrideByDataSource) {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Properties info = new Properties();
info.setProperty("user", "test");
info.setProperty("password", "test");
String connectionString = "jdbc:sqlserver://localhost\\SQLEXPRESS1:1433;databaseName=mybase;";
return DriverManager.getConnection(connectionString, info);
} else {
return super.getConnection();
}
}
}
8.如何使用SWT（標準小部件工具包）組件？
創建一個新的Java項目。為此，請選擇文件>新建> Java項目。在項目向導中，輸入項目的名稱，例如“ swtfx”。在項目屬性中，將一個關系添加到“ Standard Widget Toolkit（SWT）”庫，以設計應用程序GUI。還要添加用于處理報告的庫：stimulsoft.reports.fx-core-2011.1.1000.jarstimulsoft.reports.fx-designer-2011.1.1000.jar，stimulsoft.reports.fx-viewer-2011.1.1000.jar，stimulsoft。 reports.fx-swt-2011.1.1000.jar。
然后使用包my.swt和報告名稱創建一個新類。
package my.swt;
import java.io.File;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import com.stimulsoft.StiConfig;
import com.stimulsoft.StiReportSwt;
import com.stimulsoft.library.StiException;
import com.stimulsoft.widgets.DesignerFx;
public class Reports {
public static void main(String[] args) {
initReport();
Display display = new Display();
Shell shell = new Shell(display);
GridLayoutgridLayout = newGridLayout();
gridLayout.marginHeight=0;
gridLayout.marginWidth=0;
shell.setLayout(gridLayout);
shell.setText("My report");
try {
DesignerFx designer = new DesignerFx(shell, SWT.NO);
GridDatagridData = new GridData(GridData.FILL_BOTH);
designer.getComposite().setLayoutData(gridData);
} catch (StiException e) {
e.printStackTrace();
Label label = new Label(shell, SWT.NONE);
label.setLayoutData(newGridData(SWT.BEGINNING, SWT.CENTER, false, false));
label.setText("failed to create reports designer");
}
shell.setMaximized(true);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
Private static void initReport() {
try {
File stiDir = new File("D:/stimulsoft");
StiConfig stiConfig = new StiConfig(stiDir);
StiReportSwt.init(stiConfig);
} catch (StiException e) {
e.printStackTrace();
}
}
}
可以通過事件分發和修改報告和選項。為此，請按以下方式更改Reports.java中的代碼。
package my.swt;
import java.io.File;
import java.util.HashMap;
import java.util.Map;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.events.SelectionListener;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import com.stimulsoft.StiConfig;
import com.stimulsoft.StiReportSwt;
import com.stimulsoft.library.StiException;
import com.stimulsoft.widgets.ViewerFx;
public class Reports {
Display display = new Display();
Shell shell = new Shell(display);
private final ViewerFx viewer;
public Reports() throws StiException {
shell.setLayout(new GridLayout(2, false));
Map<String, String> params = new HashMap<String, String>();
params.put("Variable1", "My parameter");
viewer = new ViewerFx(shell, SWT.NO, "SimpleList.mrt", params);
GridDatagridData = new GridData(GridData.FILL_BOTH);
viewer.getComposite().setLayoutData(gridData);
Button button = new Button(shell, SWT.PUSH);
button.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));
button.setText("update report");
button.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent arg0) {
try {
Map<String, String>paramsNew = new HashMap<String,String>();
paramsNew.put("Variable1", "My new parameter");
viewer.assignReport("SimpleList.mrt", paramsNew);
} catch (Exception e) {
e.printStackTrace();
}
}
public void widgetDefaultSelected(SelectionEvent arg0) {
}
});
shell.setMaximized(true);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
public static void main(String[] args) {
try {
initReport();
new Reports();
} catch (StiException e) {
e.printStackTrace();
}
}
private static void initReport() throws StiException {
StiConfigstiConfig = new StiConfig(new File("D:/stimulsoft"));
StiReportSwt.init(stiConfig);
}
}
這將導致以下結果：
單擊更新報告按鈕后，報告將被更新：
使用呈現報告的組件時，應在運行該應用程序之前配置該應用程序。應該創建以下方法。
private static void initReport() throws StiException {
File stiDir = new File("D:/Stimulsoft");
new Resource().copyAll(stiDir);
StiSwtConfig stiConfig = new StiSwtConfig(stiDir);
StiReportSwt.init(stiConfig);
}
將在其中 定義帶有stimulsoft.properties文件的主應用程序目錄。初始化與針對Web應用程序描述的初始化相同。還可以為設計者和查看者覆蓋應用程序的端口。例如：
private static void initReport() throws StiException {
// Initialization is identical to that described for the web application
File stiDir = new File("D:/Stimulsoft");
new Resource().copyAll(stiDir);
StiSwtConfig stiConfig = new StiSwtConfig(stiDir);
// ---------------------------------------------------------
// need to override the standard methods
// another comment
stiConfig.setLoadClass(MyLoadAction.class).setSaveClass(MySaveAction.class);
stiConfig.setXMLDataClass(MyXMLDataAction.class).setLoadDataClass(MyLoadDataAction.class);
stiConfig.setViewerPort(7845).setDesignerPort(8789);
// ---------------------------------------------------------
StiReportSwt.init(stiConfig);
}
也可以將設計器和查看器組件用作對話框。組件類別：
com.stimulsoft.widgets.DesignerFxDialog
com.stimulsoft.widgets.ViewerFxDialog
使用Designer組件的示例：
package my.swt;
import java.io.File;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.events.SelectionListener;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import com.stimulsoft.StiConfig;
import com.stimulsoft.StiReportSwt;
import com.stimulsoft.library.StiException;
import com.stimulsoft.widgets.DesignerFxDialog;
public class DialogReports {
public static void main(String[] args) {
try {
initReport();
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout());
final DesignerFxDialog dialog = new DesignerFxDialog(shell,
SWT.RESIZE | SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL);
dialog.setSize(1250, 800);
Button button = new Button(shell, SWT.PUSH);
button.setText("open dialog");
button.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent arg0) {
try {
dialog.open("SimpleList.mrt");
} catch (StiException e) {
}
}
public void widgetDefaultSelected(SelectionEvent arg0) {
}
});
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
} catch (StiException e) {
e.printStackTrace();
}
}
private static void initReport() throws StiException {
File stiDir = new File("D:/stimulsoft");
StiConfig stiConfig = new StiConfig(stiDir);
StiReportSwt.init(stiConfig);
}
}
