我遇到了这个问题我无法使用通用DAO调用hibernate存储过程，显然HQL是错误的：
这就是我打电话给SP的方式：
@SuppressWarnings("unchecked")
public List<Object> consultaNamedQuery(String[] args) {
String decimalPattern = "([0-9]*)\\.([0-9]*)";
session=sf.getCurrentSession();
//gets the name of the parameter
Query q=session.getNamedQuery(args[0]);
for (int i = 1; i < args.length; i+=2) {
//args[i] = name of parameter - args[i+1] = value of parametro
if(Pattern.matches(decimalPattern, args[i+1]))
q.setInteger(args[i], Integer.parseInt(args[i+1]));
else
q.setString(args[i], args[i+1]);
}
System.out.println(":::"+q.toString());
System.out.println(":::"+q.list().size());
return q.list();
}
这是将参数传递给通用DAO的地方：
public JSONObject getPresenciaGas(String parametros) {
/*
//parametros de entrada
JSONObject obj = new JSONObject(parametros);
JSONObject datos = obj.getJSONObject("parametros");
String region = datos.getString("region");
int desplazamiento = datos.getInt("desplazamiento");
*/
//json de salida con imagen de presencia de gas en sector
JSONObject objPrincipal = new JSONObject();
List<Object> o = new ArrayList<Object>();
// o = servicioGenericoCRUD.consulta("from reporte_tipologias_presencia('"+region+"',"+desplazamiento+",1)");
o = servicioGenericoCRUD.consulta("call reporte_tipologias_presencia('Toluca',0,1)");
System.out.println(o.size());
try {
for(Object s : o){
//process data
}
日志：

编辑：使用命名查询添加类的定义：
@NamedNativeQueries(
{
@NamedNativeQuery(
name = "reporteGasRegional",
query = "CALL reporte_gas_region(:region)",
resultClass = ReporteGasRegional.class
)
}
)
@Entity(name="reporte_gas_regional")
public class ReporteGasRegional {
@Id private int gid;
//more variables & setter and getters
答案 0 :(得分：1)
我正在纠正这个答案。在我看来，你有以下几个问题：
query = "CALL reporte_gas_region(:region)",
使用＃3优于＃2的好处是，您可以将您的回复作为ReporteGasRegional列表返回，这样您就不必进行一堆投射。如果使用＃2，那么您将获得响应为List of Object数组，并且必须将每个字段显式地转换为其数据类型。
