我有这个问题我是不能用一般的DAO与Hibernate调用存储过程调用存储过程与本地命名查询，显然HQL是错误的：Hibernate的错误尝试
这是我怎么叫SP：
@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();
}
这里就是参数传递给通用的DAO：
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：添加类的定义与命名查询：
@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
它看起来像存储过程退出并返回结果。 –
