Question

我正在尝试将hibernate与spring集成。这是我的代码：

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包）

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;
    }

}

最后是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>

没有错误，但它不会从数据库中读取数据。如果我使用SessionFactory sf = (SessionFactory)appContext.getBean("sessionFactory");替换Main.java中的SessionFactory sf = new Configuration().configure().buildSessionFactory();，它可以正常工作。所以问题可能在Config.java，也许我的做法根本不是那么好？无论如何数据库连接正在运行，里面有一些记录。结束这个我粘贴我的控制台结果：

Answer 1

你的hibernate.hmb.xml应该是hibernate cfg文件，但在你的情况下它不是必需的，因为你创建了Config.java并且你声明了LocalSessionFactoryBean。在Config.java的sessionFactory方法中，你传递的是asfb.setMappingResources（“hibernate.cfg.xml”）; .. setMappingResources方法是期待hbm文件ex：mapping.hbm.xml。

Java Spring + Hibernate LocalSessionFactoryBean无效
