Java Spring + Hibernate LocalSessionFactoryBean not working

Question

I'm trying to integrate hibernate with spring. Here are my codes:

Main.java

import java.util.List;
import local.bb.entities.Words;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

    public static void main(String args[]) {

        ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("spring.xml");
        SessionFactory sf = (SessionFactory)appContext.getBean("sessionFactory");
        Session s = sf.openSession();

        try {

            List<Words> words = s.createCriteria(Words.class).list();
            int i=1;
            for( Words w : words ) {
                System.out.println( "["+ (i++) +"]" + w.getWord());
            }

        } catch(Exception e) {
            e.printStackTrace();
        }

        sf.close();

    }

}

spring.xml

    <?xml version='1.0' encoding='UTF-8' ?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:p="http://www.springframework.org/schema/p"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:tx="http://www.springframework.org/schema/tx"
        xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="
            http://www.springframework.org/schema/beans 
            http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
            http://www.springframework.org/schema/aop 
            http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
            http://www.springframework.org/schema/tx 
            http://www.springframework.org/schema/tx/spring-tx-4.0.xsd

            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <context:component-scan base-package="local.bb.config">
    </context:component-scan>

    <aop:aspectj-autoproxy proxy-target-class="true"/>
</beans>

Config.java(local.bb.config package)

import java.util.Properties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;

@Configuration
public class Config {

    @Bean
    DriverManagerDataSource dataSource() {
        DriverManagerDataSource dmds = new DriverManagerDataSource("jdbc:mysql://localhost:3306/java?zeroDateTimeBehavior=convertToNull");
        dmds.setUsername("root");
        return dmds;
    }

    @Bean
    LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean asfb = new LocalSessionFactoryBean();
        asfb.setDataSource(dataSource());
        asfb.setMappingResources("hibernate.cfg.xml");
        Properties props = new Properties();
        props.setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
        asfb.setHibernateProperties(props);
        return asfb;
    }

}

And finally 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.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/java?zeroDateTimeBehavior=convertToNull</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.hbm2ddl.auto">validate</property>
    <mapping class="local.bb.entities.Users" />
    <mapping class="local.bb.entities.Words" />
  </session-factory>
</hibernate-configuration>

There are no errors but it doesn't read data from database. If I replace SessionFactory sf = (SessionFactory)appContext.getBean("sessionFactory"); in Main.java, with SessionFactory sf = new Configuration().configure().buildSessionFactory(); it works fine. So the problem may be in the Config.java and maybe my approach isn't that good at all? Anyway database connection is working and there are some records inside. Ending this I paste my console result:

Answer 1

your hibernate.hmb.xml should be hibernate cfg file but in your case it's not required as you have created Config.java and in that you declared LocalSessionFactoryBean. In sessionFactory method of Config.java you are passing asfb.setMappingResources("hibernate.cfg.xml");.. setMappingResources method is expecting hbm file ex: mapping.hbm.xml.
