使用代碼：

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();

我尋找這個錯誤，但coudn't找到任何解決辦法呢。

我該如何解決這個問題？（老實說，我不明白爲什麼會發生）

什麼是你使用的底層數據庫？ – kyiu

@KHY我正在使用mysql –

在您的hibernate.cfg.xml文件中設置MySQLDialect。 –

我原來決心我的答案寫我自己的方言類作爲

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()); 

} 
}

，並添加到disptcher-servlet.xml中的

<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>

及其對我工作的罰款。

謝謝，它也適用於我。 –

像這樣創建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>

的問題是返回類型。什麼是my_sp_test的返回類型？ JDBC驅動程序將返回類型報告爲-1，但Hibernate不知道如何解釋該類型，並且您沒有告訴它如何去做。

我的猜測是，my_sp_test沒有返回類型，但你試圖通過選擇查詢設施來使用它。如果my_sp_test沒有返回，那麼你可以嘗試調用Query.executeUpdate() insteasd Query.list()。我不能肯定地說這會起作用，因爲executeUpdate確實意味着處理UPDATE/DELETE查詢。同樣，如果是這種情況，最好的辦法就是下載到JDBC。
