使用代码:
query = sessionFactory.getCurrentSession().createSQLQuery("CALL my_sp_test(:gender_id,:category_id,:is_date_criteria_on,:from_date,:to_date,:unit_sold_above)");
query.setParameter("gender_id",bestSellCriteriaForms[0].getSelectedGender()); query.setParameter("category_id",bestSellCriteriaForms[0].getSelectedDepartment());
query.setParameter("unit_sold_above", 200);
query.setParameter("is_date_criteria_on", true);
query.setParameter("from_date", date);
query.setParameter("to_date", date);
//Get query as list
reportList = query.list();
我正在搜索此错误,但尚未找到任何解决方案。
如何解决此问题? (老实说,我无法理解为什么会发生这种情况)

我通过将自己的方言课写为
来重新开始我的答案import java.sql.Types;
import org.hibernate.Hibernate;
import org.hibernate.dialect.MySQLDialect;
import org.hibernate.dialect.function.StandardSQLFunction;
public class CustomeDialect extends MySQLDialect {
public CustomeDialect(){
registerFunction("group_concat", new StandardSQLFunction("group_concat", Hibernate.STRING));
registerFunction("coalesce", new StandardSQLFunction("coalesce", Hibernate.STRING));
registerHibernateType(Types.LONGVARCHAR, Hibernate.TEXT.getName());
}
}
并以
的形式添加到disptcher-servlet.xml中<bean id="MySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="mydbDatasource"/>
<property name="configurationClass">
<value>org.hibernate.cfg.AnnotationConfiguration</value>
</property>
<property name="packagesToScan" value="com.example.entity" />
<property name="hibernateProperties">
<value>
hibernate.dialect=com.example.utils.CustomeDialect
</value>
</property>
</bean>
它对我来说很好。

像这样创建hibernate.cfg.xml。
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">password</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mkyong</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property>
<mapping resource="com/mkyong/common/Stock.hbm.xml"></mapping>
</session-factory>

问题是返回类型。 my_sp_test的返回类型是什么? JDBC驱动程序将返回类型报告为-1,但Hibernate不知道如何解释它并且您没有告诉它如何。
我的猜测是my_sp_test没有返回类型,但您尝试通过select查询工具使用它。如果my_sp_test没有返回,那么您可以尝试调用Query.executeUpdate()
的{{1}} insteasd。我不能肯定这会起作用,因为Query.list()
真的是用于处理UPDATE / DELETE查询。同样,如果是这种情况,最好的办法是下载到JDBC。
