需要一些帮助的人。 我只是学习使用Spring和Hibernate，所以我可能在某处犯了一个基本错误，但我无法弄清楚在哪里。 我尝试在tomcat 8服务器上运行我的应用程序，我使用BoneCP作为DataSource实现和MySQL，我在没有Maven的情况下构建它。

之前我没有遇到任何问题

我有我的Spring XML文件 springdispatcher-servlet.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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd">

<context:component-scan base-package="main.statisthira"/>
<context:property-placeholder location="WEB-INF/properties/gers.properties"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix"><value>/WEB-INF/jsp/</value></property>
    <property name="suffix"><value>.jsp</value></property>
</bean>

<bean name="dataSource" class="com.jolbox.bonecp.BoneCPDataSource">
    <property name="username" value="gers"/>
    <property name="password" value="password"/>
    <property name="user" value="jdbc:mysql://localhost:3306/statisthira"/>
    <property name="driverClass" value="com.mysql.jdbc.Driver"/>
</bean>

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" lazy-init="true">
    <property name="dataSource" ref="dataSource"/>

</bean>

<bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<bean name="songNewDAO" class="main.statisthira.dao.SongNewDAO">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

然后我的Hibernate XML配置文件 hibernate.cfg.xml 。 hibernate.dialect是明确定义的，但没有任何反应

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "classpath://org/hibernate/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.cache.use_second_level_cache">false</property>
        <property name="hibernate.cache.use_query_cache">false</property>
        <property name="show_sql">false</property>
        <mapping package="main.statisthira.model"/>
    </session-factory>
</hibernate-configuration>

我尝试在简单的DAO中使用sessionFactory 

    @Transactional
    @Repository
    public class SongNewDAO implements ISongNewDAO{

        @Autowired
        private SessionFactory sessionFactory;

        @Override
        public Song getSongById(String id){
            return (Song) sessionFactory.getCurrentSession().byId(id);
        }

        public SessionFactory getSessionFactory() {
            return sessionFactory;
        }

        public void setSessionFactory(SessionFactory sessionFactory) {
            this.sessionFactory = sessionFactory;
        }

no error at compilation, but when I try to access one of my controller that uses the DAO, I get a long error message, ending with :

我离线工作，thread建议在

中进行一些更改

web.xml 文件

<?xml version="1.0" encoding="UTF-8"?>

http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"          版本=＆＃34; 3.1＆＃34;＆GT;

    <url-pattern>/</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>/WEB-INF/jsp/home.jsp</welcome-file>
</welcome-file-list>

我的Controller Home.java 

Controller

@RequestMapping（＆＃34; /家＆＃34） 公共课主页{

@Autowired
private ISongNewDAO songNewDAO;

@RequestMapping(method = RequestMethod.GET)
public String helloWorld(ModelMap model) {
    Song song = songNewDAO.getSongById("0isp4utk4v");
    model.addAttribute("song", song);
    model.addAttribute("message", "Hello world");
    return "home";
}

public ISongNewDAO getSongNewDAO() {
    return songNewDAO;
}

public void setSongNewDAO(ISongNewDAO songNewDAO) {
    this.songNewDAO = songNewDAO;
}

答案 0 :(得分：1)

您需要在sessionFactory bean中指定hibernate配置文件的位置：

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" lazy-init="true">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
