官网下载试用安装工具Crystal Reports，注册获得试用期30天。
二.配置数据源Crystal Reports 2008(水晶报表) JDBC连接mysql数据库 - Hongten - 博客园
三.优缺点使用Crystal Reports尝试配置模板的体验，主要与Jasper Studio对比。
3.1 优点
1.流式布局，交互类似office
2.官方demo丰富
3.2 缺点
1.通过URL加载的图片不支持https，只接受http
Does Crystal Reports support secure (HTTPS) images - Stack Overflow
2.相关教程博客很少
3.集成至开发环境对C#友好，JAVA对eclipse友好，无idea开发控件，官方demo通过jsp的形式查看报表
四.集成到项目4.1 SDK
由于官方没有提供idea插件，需要额外引入依赖项文件，下载地址如下，在该页面中下载 Runtime Libraries：
SAP Crystal Reports, version for Eclipse - Downloads
值得注意的是，直接从Crystal Reports工具的lib中也可以找到看上去相似的sdk文件，接口完全相同但是实现完全不同，不可引入项目使用。
maven资源库无所需依赖项，需要在项目配置中单独添加lib文件。
官方API文档：
Overview (Report Application Server Java SDK)
4.2 实战
官方提供了大量demo程序：
Crystal Reports Java SDK Samples - Business Intelligence (BusinessObjects) - Community Wiki
下面总结一些常用API范例：
4.2.1导出PDF到浏览器
配置模板如下：
输出PDF样例代码如下：
// 读取模板文件ReportClientDocument reportClientDoc = new ReportClientDocument();reportClientDoc.open("./reports/jrc_export_report.rpt", 0);ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream) reportClientDoc. getPrintOutputController().export(ReportExportFormat.PDF);reportClientDoc.close();// 输出PDFbyte[] buffer = new byte[byteArrayInputStream.available()];int bytesRead = 0;response.reset();response.setHeader("Content-disposition", "inline;filename=report.pdf");response.setContentType("application/pdf");while ((bytesRead = byteArrayInputStream.read(buffer)) != -1) { response.getOutputStream().write(buffer, 0, bytesRead);}response.getOutputStream().flush();response.getOutputStream().close();PDF效果图如下所示：
4.2.2数据库连接
在第一个样例中，数据库连接配置在模板中，不需要由代码配置，这也是默认的连接方式。
如需要更改数据库连接，参考官方实例change_db_location（CRJ12_Sample_CodesRCAPI），大致如下：
String REPORT_NAME = "change_db_location/simplereport.rpt";String DBUSERNAME = "vantech";String DBPASSWORD = "vantech";String CONNECTION_STRING = "!com.microsoft.jdbc.sqlserver.SQLServerDriver!jdbc:microsoft:sqlserver://10.50.212.103:1433;DatabaseName={database};user={userid};password={password}";String TRUSTEDCON = "false";String PREQESERVERNAME = "jdbc:microsoft:sqlserver://10.50.212.103:1433";String SERVERTYPE = "JDBC (JNDI)";String DATABASE_DLL = "crdb_jdbc.dll";String DATABASE = "Xtreme";String DBCLASSNAME = "com.microsoft.jdbc.sqlserver.SQLServerDriver";String USEJDBC = "true";String DATABASE_NAME = "Xtreme";String SERVERNAME = "jdbc:microsoft:sqlserver://10.50.212.103:1433";String CONNECTIONURL = "jdbc:microsoft:sqlserver://10.50.212.103:1433";String SERVER = "10.50.212.103";//Open report.ReportClientDocument boReportClientDocument = new ReportClientDocument();boReportClientDocument.open(REPORT_NAME, 0);// Set DB Username and PasswordboReportClientDocument.getDatabaseController().logon(DBUSERNAME, DBPASSWORD);// Create the two connectioninfo objects to useIConnectionInfo oldConnectionInfo = new ConnectionInfo();IConnectionInfo newConnectionInfo = new ConnectionInfo();// Assign the old Connection info to the reports current infoDatabaseController dbController = boReportClientDocument.getDatabaseController();oldConnectionInfo = dbController.getConnectionInfos(null).getConnectionInfo(0);// If this connection needed parameters, we would use this field.Fields pFields = null;// Create a new propertybag for the new locationPropertyBag boPropertyBag1 = new PropertyBag();// Set new table logon propertiesboPropertyBag1.put("JDBC Connection String", CONNECTION_STRING);boPropertyBag1.put("Trusted_Connection", TRUSTEDCON);boPropertyBag1.put("PreQEServerName", PREQESERVERNAME);boPropertyBag1.put("Server Type", SERVERTYPE);boPropertyBag1.put("Database DLL", DATABASE_DLL);boPropertyBag1.put("Database", DATABASE);boPropertyBag1.put("Database Class Name", DBCLASSNAME);boPropertyBag1.put("Use JDBC", USEJDBC);boPropertyBag1.put("Database Name", DATABASE_NAME);boPropertyBag1.put("Server Name", SERVERNAME);boPropertyBag1.put("Connection URL", CONNECTIONURL);boPropertyBag1.put("Server", SERVER);// Assign the properties to the connection infonewConnectionInfo.setAttributes(boPropertyBag1);// Set the DB Username and PwdnewConnectionInfo.setUserName(DBUSERNAME);newConnectionInfo.setPassword(DBPASSWORD);// The Kind of connectionInfos is SQLnewConnectionInfo.setKind(ConnectionInfoKind.SQL);// set the parameters to replace.// The 4 options are:// _doNotVerifyDB// _ignoreCurrentTableQualifiers// _mapFieldByRowsetPosition// _useDefaultint replaceParams = DBOptions._ignoreCurrentTableQualifiers + DBOptions._doNotVerifyDB;// Now replace the connectionsdbController.replaceConnection(oldConnectionInfo, newConnectionInfo, pFields, replaceParams);4.2.3动态注入参数
参考样例：Java_CRJ12_Web_Set_Parameters（CRJ12_Sample_CodesViewingExport）
模板配置如下：
数据填充示例如下：
ReportClientDocument document = new ReportClientDocument();document.setReportAppServer(ReportClientDocument.inprocConnectionString);document.open("./reports/Java_CRJ12_Web_Set_Parameters.rpt", OpenReportOptions._openAsReadOnly);ParameterFieldController parameterFieldController = document.getDataDefController() .getParameterFieldController();parameterFieldController.setCurrentValue("", "StringParam", "Hello");parameterFieldController.setCurrentValue("sub", "StringParam", "Subreport string value");parameterFieldController.setCurrentValue("", "BooleanParam", true);parameterFieldController.setCurrentValue("", "CurrencyParam", 123.45);parameterFieldController.setCurrentValue("", "NumberParam", 123);Calendar calendar = Calendar.getInstance();calendar.clear();// Ensure h:m:s and milliseconds clearedcalendar.set(2004, Calendar.FEBRUARY, 17);// February 17, 2004 - Month is 0-based.parameterFieldController.setCurrentValue("", "DateParam", calendar.getTime());calendar.clear();calendar.set(2002, Calendar.JUNE, 12, 8, 23, 15);parameterFieldController.setCurrentValue("", "DateTimeParam", calendar.getTime());calendar.clear();calendar.set(2002, Calendar.JUNE, 12, 13, 44, 59);parameterFieldController.setCurrentValue("", "TimeParam", calendar.getTime());// Multi-valued stringparameterFieldController.setCurrentValues("", "StringMultiParam", new Object[]{"One String", "Two String", "Three String"});// Range valueParameterFieldRangeValue parameterFieldRangeValue = new ParameterFieldRangeValue();parameterFieldRangeValue.setBeginValue(1);parameterFieldRangeValue.setEndValue(100);parameterFieldRangeValue.setLowerBoundType(RangeValueBoundType.inclusive);parameterFieldRangeValue.setUpperBoundType(RangeValueBoundType.inclusive);parameterFieldController.setCurrentValue("", "NumberRangeParam", parameterFieldRangeValue);// Multi Range valuesParameterFieldRangeValue[] parameterFieldRangeValues = new ParameterFieldRangeValue[2];parameterFieldRangeValues[0] = new ParameterFieldRangeValue();parameterFieldRangeValues[0].setBeginValue(12);parameterFieldRangeValues[0].setEndValue(15);parameterFieldRangeValues[0].setLowerBoundType(RangeValueBoundType.inclusive);parameterFieldRangeValues[0].setUpperBoundType(RangeValueBoundType.exclusive);parameterFieldRangeValues[1] = new ParameterFieldRangeValue();parameterFieldRangeValues[1].setBeginValue(100);parameterFieldRangeValues[1].setEndValue(200);parameterFieldRangeValues[1].setLowerBoundType(RangeValueBoundType.exclusive);parameterFieldRangeValues[1].setUpperBoundType(RangeValueBoundType.exclusive);parameterFieldController.setCurrentValues("", "NumberMultiRangeParam", parameterFieldRangeValues);最终输出PDF效果：
4.2.4子报表
与4.2.3采用相同示例，配置模板如下：
实际展示效果如4.2.3
