SSH整合方案一(带有hibernate.cfg.xml)

整体结构

1.导入响应的jar包

2.在web.xml中配置struts的过滤器和spring整合web的监听器

   <!--配置Spring整合web的监听器-->

    <listener>

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

    </listener>

    <context-param>

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

        <param-value>classpath:applicationContext.xml</param-value>

    </context-param>

    <!--配置struts的过滤器-->

    <filter>

        <filter-name>struts</filter-name>

        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>struts</filter-name>

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

    </filter-mapping>

配置struts核心过滤器和Spring监听器

3.编写Action,使用继承ActionSupport的方式创建Action,并使用模型驱动来封装表单

在Action中编写需要调用的Service层的属性,并提供set方法

public class CustomerAction extends ActionSupport implements ModelDriven{

    private CustomerService customerService;

    public void setCustomerService(CustomerService customerService) {

        this.customerService = customerService;

    }

    //必须手动new

    private Customer customer=new Customer();

    //模型和属性驱动

    /**

     * 保存客户

     * @return

     */

    public String add(){

        customerService.save(customer);

        return NONE;

    }

    @Override

    public Object getModel() {

        return customer;

    }

}

CustomerAction

4.编写struts的配置文件,struts.xml中我们主要配置Action,将Action的创建由Spring来管理,在struts.xml主要对bean的引用

(1)将Action的创建由Spring管理

 <!--配置Action必须多例-->

    <bean id="customerAction" class="cn.zqr.action.CustomerAction" scope="prototype">

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

    </bean>

Spring管理的customerAction

(2)在struts.xml主要对bean的引用

 <package name="crm" namespace="/" extends="struts-default">

        <!--Action由Spring管理,class值为Spring的id-->

        <action name="customer_*" class="customerAction" method="{1}">

        </action>

    </package>

struts引用Spring创建的Action

5.编写service层,service中主要需要对dao层的调用,和开启事务两步

对dao层的调用,采用Spring对bean的管理方法,在类中提供dao层的对象,并提供对应的set方法

@Transactional

public class CustomerServiceImpl implements CustomerService {

    private CustomerDao customerDao;

    public void setCustomerDao(CustomerDao customerDao) {

        this.customerDao = customerDao;

    }

    /**

     * 保存客户信息

     * @param customer

     */

    @Override

    public void save(Customer customer) {

        customerDao.add(customer);

    }

}

CustomerServiceImpl

 <!--配置service-->

    <bean id="customerService" class="cn.zqr.service.impl.CustomerServiceImpl">

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

    </bean>

    <!--配置sessionFacotry-->

    <bean class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" id="sessionFactory">

        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>

    </bean>

    <!--配置事务-->

    <bean class="org.springframework.orm.hibernate5.HibernateTransactionManager" id="transactionManager">

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

    </bean>

    <!--开始事务的注解-->

    <tx:annotation-driven/>

配置serice并配置sessionFactory,配置事务,开启注解事务

事务的管理和dao层的持久化都依赖于session,使用Spring管理sessionFactory的创建,并开始事务注解

6.编写dao层,dao层采用继承HibernateDaoSupport类的方式实现,需要使用HibernateDaoSupport类中的方法获取jdbc模板

dao层代码

public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {

    /**

     * 保存客户

     */

    @Override

    public void add(Customer customer) {

        System.out.println("持久层Customer customer"+customer);

        this.getHibernateTemplate().save(customer);

    }

}

dao层代码

dao层的配置

  <!--配置dao-->

    <bean id="customerDao" class="cn.zqr.dao.impl.CustomerDaoImpl">

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

    </bean>

Spring中dao层的配置

编写实体类和配置hibernate配置文件不做详解,代码如下:

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

<!DOCTYPE hibernate-configuration PUBLIC

    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- 必须配置 -->

        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="hibernate.connection.url">jdbc:mysql:///ssh</property>

        <property name="hibernate.connection.username">root</property>

        <property name="hibernate.connection.password">admin</property>

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- 可选配置 -->

        <property name="hibernate.show_sql">true</property>

        <property name="hibernate.format_sql">true</property>

        <property name="hibernate.hbm2ddl.auto">update</property>

        <!-- 配置C3P0的连接池 -->

        <property name="connection.provider_class">org.hibernate.c3p0.internal.C3P0ConnectionProvider</property>

        <!-- 映射配置文件 -->

<mapping resource="Customer.hbm.xml"></mapping>

    </session-factory>

</hibernate-configuration>

hibernate.cfg.xml
