Ric*_*ich 2 java sql tapestry jasper-reports
我正在使用Tapestry 5.1.0.5框架编写一个用Java编写的Web应用程序.这个框架没有对JasperReports的开箱即用支持,所以我编写了一个修改ChenilleKit的JasperReport服务的服务.我不依赖于ChenilleKit版本,而是使用JasperReport 3.5.0依赖.这可能不是必要的信息,但具体而言从不会受到伤害.
无论如何,我的服务工作得很好.我把它内置到webapp中,我能够编译和输出PDF,XLS,HTML和CSV格式的基本报告.但是,我在jasperReport XML文件中获取SQL以正确加载参数映射时遇到了很大的问题.
尝试使用startdate和enddate参数运行报表时出现以下错误.
SQLException: Missing IN or OUT parameter at index:: 1
SQL知识会说这意味着我有某种形式的参数没有传递给SQL.调试语句向我表明我正在传递参数,并且至少有一些正在进入XML报告.
例如,我将三个参数传递给报表,Title,StartDate和EndDate.标题显示在报告的呈现中,但StartDate和EndDate似乎在翻译中丢失了？
我不确定我缺少什么,因为几乎相同的代码在我公司的基于JSP-Tomcat-Servlet的JasperReports应用程序中运行.
无论如何,我将开始显示代码并解释发生了什么:
public StreamResponse getReport(String reportTitle, ExportFormat formMode, Date startDate, Date endDate) {
Map<String,String> parameterMap = loadParameters(reportTitle);
Connection conn = null;
OutputStream os = new ByteArrayOutputStream();
try{
conn = Report.getConnection();
Resource resc = new ContextResource(cimpl, "src/main/webapp/reports/"+reportTitle+".xml");
log.debug("Calling fillAndExport to fetch the report " + reportTitle);
log.debug("resource="+resc+"\n"+"formMode="+formMode+"\n"+"parameterMap="+parameterMap+"\n"+"conn="+conn+"\n"+
"outputStream="+os);
SimpleDateFormat repDate = new SimpleDateFormat("MM/dd/yyyy HH:mm");
parameterMap.put("StartDate", repDate.format(startDate));
parameterMap.put("EndDate", repDate.format(endDate));
log.debug("StartDate into report: " + parameterMap.get("StartDate"));
log.debug("EndDate into report: " + parameterMap.get("EndDate"));
js.fillAndExport(resc, formMode, parameterMap, conn, os);
SimpleDateFormat sdf = new SimpleDateFormat("MMMddyyyy");
return new JasperStreamResponse((ByteArrayOutputStream) os, formMode, reportTitle+"-"+sdf.format(startDate)+"-"
+sdf.format(endDate));
}catch (Exception e){
log.error("Caught exception while trying to execute the report fillAndExport service method.");
throw new TapestryException("Issue executing report", e);
} finally {
if(conn != null){
try {
conn.close();
} catch (SQLException e) {
System.out.println("Could not close the JDBC connection!!");
}
}
}
}
简而言之,我加载报表资源,并添加StartDate和EndDate参数(Title已经在parameterMap中).然后我调用JasperService,使用fillAndExport生成报告.如果没有例外,它将以流的形式返回到浏览器.
这是伴随的调试语句给定时间我得到异常:

因此,您可以看到值一直在参数映射中直到JasperService调用JapserReports API.现在我将展示JasperService代码和一些报告,以便您可以看到SQL破坏事物.
JasperService:
/**
* Fills the report design loaded from the supplied input resource and returns the generated report object.
* <p/>
* if parameter <em>jasperPrint<em> not null, the data filled into <em>jasperPrint</em>
* instead of returns a new jasper print object.
*
* @param jasperPrint

* @param parameterMap the parameter map
* @param dataSource the datasource, either a JRDataSource or an SQL JDBC Connection.

*/
public JasperPrint fillReport(JasperPrint jasperPrint, Resource inputResource, Map parameterMap, Object dataSource) throws JRException
{
JasperReport jasperReport = doCompileReportSource(inputResource);
JasperPrint actualJasperPrint;
logger.debug("In fillReport, parameterMap is : " + parameterMap + "\n startDate: " + parameterMap.get("StartDate") + "\n endDate: " + parameterMap.get("EndDate"));
try
{
if (dataSource != null && dataSource instanceof JRDataSource)
actualJasperPrint = JasperFillManager.fillReport(jasperReport, parameterMap, (JRDataSource) dataSource);
else if(dataSource != null && dataSource instanceof Connection)
actualJasperPrint = JasperFillManager.fillReport(jasperReport, parameterMap, (Connection) dataSource);
else
actualJasperPrint = JasperFillManager.fillReport(jasperReport, parameterMap);
if (jasperPrint != null)
{
for (Object page : actualJasperPrint.getPages())
jasperPrint.addPage((JRPrintPage) page);
}
else
jasperPrint = actualJasperPrint;
return jasperPrint;
}
catch (JRException e)
{
logger.error("Caught exception in fillReport of ReportsServiceImpl {}", e);
throw new JRException(e);
}
