                </configuration>

            </plugin>

        </plugins>

    </build>

3. 创建Java 代码结构如下：

TestController:

 @Autowired

    private UsersDAO usersDAO;

    @RequestMapping(value = "/index", method = RequestMethod.GET)

    public ModelAndView indexGet(){

        List<Users> list = usersDAO.getAllUser();

        ModelAndView mv = new ModelAndView("index") ;

        mv.addObject("size", list.size());

        return mv;

    }

    @RequestMapping(value = "/", method = RequestMethod.GET)

    @ResponseBody

    public String defaultGet(){

        return "default" ;

    }

UsersDAO

public class UsersDAO {

    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {

        this.sessionFactory = sessionFactory;

    }

    public SessionFactory getSessionFactory() {

        return sessionFactory;

    }

    public List<Users> getAllUser(){

        String hsql="from Users";

        Session session = sessionFactory.openSession();

        Query query = session.createQuery(hsql);

        return query.list();

    }

}

Users

@Entity()

//@Table(name="users")

public class Users {

    public Users(){

    }

    @Id

    @GeneratedValue

    public Long id ;

    public String name;

    public String email;

    public String password;

    public Long getId() {

        return id;

    }

    public void setId(Long id) {

        this.id = id;

    }

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getEmail() {

        return email;

    }

    public void setEmail(String email) {

        this.email = email;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

}

4. 配置Spring 和 Hibernate4 Xml 设置，文件放在代码目录中的resources文件夹中

spring-hibernate.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </property>

        <property name="username" value="${jdbc.user}" />

        <property name="password" value="${jdbc.pass}" />

    </bean>

    <!-- 配置Hibernate事务管理器 -->

    <bean id="transactionManager"

          class="org.springframework.orm.hibernate4.HibernateTransactionManager">

        <property name="sessionFactory" ref="sessionFactory" />

    </bean>

    <!-- 配置事务异常封装 -->

    <bean id="persistenceExceptionTranslationPostProcessor"

          class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

    <!--  声明式容器事务管理 ,transaction-manager指定事务管理器为transactionManager -->

    <!--<aop:config expose-proxy="true">-->

        <!--&lt;!&ndash; 只对业务逻辑层实施事务 &ndash;&gt;-->

        <!--<aop:pointcut id="txPointcut" expression="execution(* com.lei.demo.service..*.*(..))" />-->

        <!--&lt;!&ndash; Advisor定义，切入点和通知分别为txPointcut、txAdvice &ndash;&gt;-->

        <!--<aop:advisor pointcut-ref="txPointcut" advice-ref="txAdvice"/>-->

    <!--</aop:config>-->

    <bean id="usersDAO" class="priv.bruce.demoproject.hibernatedemo.dao.UsersDAO">

        <property name="sessionFactory" ref="sessionFactory"></property>

    </bean>

</beans>

系统参数配置文件 persistence-mysql.properties

# jdbc.X

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://datasource?useUnicode=true&characterEncoding=utf8

jdbc.user=root

jdbc.pass=123456

hibernate.connection.driverClass=org.gjt.mm.mysql.Driver

hibernate.connection.url=jdbc:mysql://datasource?useUnicode=true&characterEncoding=utf8

hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

hibernate.connection.username=root

hibernate.connection.password=pass

hibernate.show_sql=true

hibernate.hbm2ddl.auto=create-drop

5. Spring Mvc 配置

　　5.1 webapp中增加view 用做保存 velocity模版

　　5.2 配置web.xml

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xmlns="http://java.sun.com/xml/ns/javaee"

         xmlns:web="http://java.sun.com/xml/ns/javaee"

         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

         id="WebApp_ID" version="3.0">

  <display-name>Archetype Created Web Application</display-name>

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:/spring-*.xml</param-value>

  </context-param>

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <!-- 定义DispatcherServlet -->

  <servlet>

    <servlet-name>dispatcher</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

      <!-- 默认/WEB-INF/[servlet名字]-servlet.xml加载上下文，

          如果配置了contextConfigLocation参数，

          将使用classpath:/lei-dispatcher-servlet.xml加载上下文

      -->

      <param-name>contextConfigLocation</param-name>

      <param-value>classpath:/dispatcher-servlet.xml</param-value>

    </init-param>

    <load-on-startup>1</load-on-startup>

  </servlet>

  <!-- 拦截匹配的请求，这里所有请求采用名字为lei-dispatcher的DispatcherServlet处理 -->

  <servlet-mapping>

    <servlet-name>dispatcher</servlet-name>

    <url-pattern>/</url-pattern>

  </servlet-mapping>

</web-app>

　　5.3 配置 dispatcher-servlet.xml，文件放在resources文件夹中，也可以自行配置文件所在位置。

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xmlns:p="http://www.springframework.org/schema/p"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="

        http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-3.0.xsd

        http://www.springframework.org/schema/mvc

        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

        http://www.springframework.org/schema/tx

        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd

        ">

    <!-- 启动自动扫描该包下所有的Bean(例如@Controller) -->

    <context:component-scan base-package="priv.bruce.demoproject.hibernatedemo.controller" />

    <!-- velocity解析器,替换掉原来的jsp -->

    <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">

        <property name="contentType" value="text/html;charset=UTF-8" />

        <property name="suffix" value=".html" />

    </bean>

    <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">

        <property name="resourceLoaderPath">

            <value>WEB-INF/views/</value>

        </property>

        <property name="velocityProperties">

            <props>

                <prop key="input.encoding">UTF-8</prop>

                <prop key="output.encoding">UTF-8</prop>

                <prop key="contentType">text/html;charset=UTF-8</prop>

            </props>

        </property>

    </bean>

</beans>

　　5.4 创建模板 index.html

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

size: $!size

</body>

</html>

6. 创建数据表，插入一条记录。

CREATE TABLE `users` (

  `id` bigint(20) NOT NULL AUTO_INCREMENT,

  `email` varchar(255) DEFAULT NULL,

  `name` varchar(255) DEFAULT NULL,

  `password` varchar(255) DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;

7. 启动项目输入地址： http://127.0.0.1:8080/hibernatedemo/index

　显示：size: 1

　表示项目已经运行成功
