java - 在 jasper 中将存储过程设置为 SQL 语句

Question

我有这个简单的代码:

JasperDesign jDes = JRXmlLoader.load("jasperfile.jrxml");
String sql = "Select * From table WHere address like 'St. Vincents College%'";
JRDesignQuery newQuery = new JRDesignQuery();
newQuery.setText(sql);
jDes.setQuery(newQuery);
JasperReport jRep = JasperCompileManager.compileReport(jDes);
JasperPrint jPrint = JasperFillManager.fillReport(jasperReport,null,conn);
JasperViewer.viewReport(jPrint);

基本上，打印的就是报告。我想要的不是 SELECT... 查询，我想使用一个存储过程，比方说:

ProcedureName:    GenerateReportByAddress
Parameter    :    personName

如何在 jasper 中使用 CallableStatement？

CallableStatement cstmt = con.prepareCall("{call GenerateReportByAddress(?)}");
cstmt.setString(1, "secret");

原因是:

- to make query of application encapsulated by calling only stored procedure
- to avoid SQL Injection. (because some address contains Single Quote)

Jasper Reports 不支持存储过程。临时表是正确的方法。有关详细信息，请参阅此博客条目:

How To Call Stored Procedures From JasperReports

或者，您可以将 Jasper Reports 绑定(bind)到不同的数据源。看这里:
