Mal*_*ana 4 java jasper-reports
我正在使用JasperReports生成一个报告,并假设将其导出为多种格式.但目前我只使用excel报告.
这是我的控制器代码.
InputStream in = reportTemplate.getTemplate(reportInquery.getTemplateFile());
JasperPrint print = JasperFillManager.fillReport(in, null,
new JRResultSetDataSource(reportDao.getReportData(reportInquery)));
resp = HttpConfig.setHeaders(reportInquery, resp);
Exporter exporter = reportOption.getRenderOptions(reportInquery.getFormat(), resp.getOutputStream(), print);
exporter.exportReport();

在我的配置工厂中,excel报告在调用getRenderOptions方法后配置如下.
public Exporter exporterOptions(OutputStream outputStream, JasperPrint print) {
JRXlsExporter exporter = new JRXlsExporter();
exporter.setExporterInput(new SimpleExporterInput(print));
OutputStreamExporterOutput outputStreamExporterOutput = new SimpleOutputStreamExporterOutput(outputStream);
exporter.setExporterOutput(outputStreamExporterOutput);
SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
configuration.setOnePagePerSheet(true);
configuration.setDetectCellType(true);
configuration.setMaxRowsPerSheet(100);
configuration.setRemoveEmptySpaceBetweenColumns(true);
configuration.setRemoveEmptySpaceBetweenRows(true);
exporter.setConfiguration(configuration);
return exporter;
}

创建JRResultSetDataSource我OracleCachedRowSet在上面的getReportData方法中使用了oracle .
public RowSet getReportData(ReportInqueryDTO reportInquery) {
try {
String query = getQueryById(reportInquery.getTemplateId());
Map<String, String> params = new HashMap<>();
params.put("fromDate", reportInquery.getFromDate());
params.put("toDate", reportInquery.getToDate());
params.put("appName", this.applicationName);
RowSet rowSet = namedParameterJdbcTemplate.query(query, params, new ResultSetExtractor<RowSet>() {
@Override
public RowSet extractData(ResultSet resultSet) throws SQLException, DataAccessException {
OracleCachedRowSet rs = new OracleCachedRowSet();
rs.populate(resultSet);
return rs;
}
});
rowSet.beforeFirst();
return rowSet;
} catch (Exception exception) {
log.error("getReportData failed.");
}
return null;
}

我的问题是,excel总是带有第一个缺失的记录,其中resultSet指向的光标.(例如:这rowSet.beforeFirst()意味着在第一个索引之前.我错过了这个场景中的第一个记录.)
几天我都遇到了这个问题.我想知道这是一个碧玉问题我该怎么解决它.如果无法解决,我想知道如何在第一条记录之前动态添加缓存行集?
我有几个jrxml文件,其中一个在下面添加.每个文件都遵循相同的格式.

提前致谢.
请发布您的jrxml文件.
问题可能不在您的代码中.
在Jasper中,数据源中的记录指针由接收它的每个元素递增(因此,例如,如果您在报告中有一个表,并且您将表的数据源设置为报告的数据源,它将跳过第一条记录.如果是这种情况,则必须将报告中的数据源作为参数传递给表格.
更新:
1.从服务器发送数据源作为参数,并使用不同的报告填充报告(可以为空).
2.在与bean集合相同类型的报告中删除一个新参数,我们将其命名为"DS1".
3.设置TableDatasource以使用$ P {DS1}参数.
请参阅我对如何在Table组件的帮助下显示JRBeanCollectionDataSource数据的响应 ?举个例子.
正如劳拉(Laura)在这个答案中提到的那样,数据源中的记录指针随着接收它的每个元素而递增。由于我正在传递结果集,因此我认为再次将结果集作为参数传递是没有意义的。最后我决定在结果集的开头添加一个空记录。
在getReportData上述问题的方法中,您可以按照以下方法来完成。
RowSet rowSet = namedParameterJdbcTemplate.query(query, params, new ResultSetExtractor<RowSet>() {
@Override
public RowSet extractData(ResultSet resultSet) throws SQLException, DataAccessException {
OracleCachedRowSet rs = new OracleCachedRowSet();
rs.populate(resultSet);
// Have to add a empty row, because jasper is not displaying
// the first row of report.
rs.setReadOnly(false);
rs.beforeFirst();
rs.moveToInsertRow();
int numCol = rs.getMetaData().getColumnCount();
for (int i = 1; i < numCol + 1; i++) {
// Add null inserted row to each column
rs.updateNull(i);
}
rs.insertRow();
rs.beforeFirst();
return rs;
}
});
