ssh框架初步搭载

1.导入jar包
2.创建web.xml文件，配置spring监听器和struts2的过滤器

<!-- Spring框架使用监听器,服务器启动的时候加载Spring的配置文件 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- 监听器默认加载WEB-INF/application.xml -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>

<!-- Struts2使用核心过滤器 -->    <filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

3.配置db.properties文件加载数据库的基本配置

jdbcUrl=jdbc:mysql://localhost:3306/myshop?useUnicode=true&characterEncoding=utf8driverClass=com.mysql.jdbc.Driveruser=rootpassword=rootinitialPoolSize=10maxPoolSize=30

4.applicationContext的配置
（一）

 <!-- 导入外部的properties配置文件 -->    <context:property-placeholder location="classpath:db.properties" />

（二）

<!-- 配置c3p0数据源 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">        <property name="jdbcUrl" value="${jdbcUrl}"></property>        <property name="driverClass" value="${driverClass}"></property>        <property name="user" value="${user}"></property>        <property name="password" value="${password}"></property>        <!--初始化时获取三个连接，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->        <property name="initialPoolSize" value="${initialPoolSize}"></property>        <!--连接池中保留的最小连接数。Default: 3 -->        <property name="minPoolSize" value="3"></property>        <!--连接池中保留的最大连接数。Default: 15 -->        <property name="maxPoolSize" value="${maxPoolSize}"></property>        <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->        <property name="acquireIncrement" value="3"></property>        <!--最大空闲时间，1800秒内未使用则连接被丢弃，若为0则永不丢弃。Default: 0 -->        <property name="maxIdleTime" value="1800"></property>    </bean>

（三）sessionFactory的配置

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">        <!--配置数据库属性 -->        <property name="dataSource" ref="dataSource"></property>        <!--配置hibernate属性 -->        <property name="hibernateProperties">            <props>                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>                <prop key="hibernate.show_sql">true</prop>                <prop key="hibernate.hbm2ddl.auto">update</prop>                <prop key="javax.persistence.validation.mode">none</prop>            </props>        </property>        <property name="mappingLocations">            <list>                <value>classpath:cn/itcast/shop/*/entity/*.hbm.xml</value>             </list>        </property>    </bean>

(四) 事务的配置
两种方式：
①

<!-- 事务管理 -->    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean><!-- 事务通知 -->    <tx:advice id="txAdvice" transaction-manager="txManager">        <tx:attributes>            <tx:method name="find*" read-only="true"/>            <tx:method name="get*" read-only="true"/>            <tx:method name="list*" read-only="true"/>            <tx:method name="*" rollback-for="Throwable"/>        </tx:attributes>    </tx:advice><!-- aop配置被事务控制的类 -->    <aop:config>        <aop:pointcut id="serviceOperation" expression="bean(*Service)"/> <!-- 扫描以Service结尾的bean --><!-- <aop:pointcut id="serviceOperation" expression="execution(* cn.itcast..service.impl.*.*(..))"/>  --><!--处理事务的类具体落实到service路径的配置 -- >        <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/>    </aop:config>

②在service类前加上@Transactional，声明这个service所有方法需要事务管理。每一个业务方法开始时都会打开一个事务。

<!-- 声明式事务管理 -->    <!-- 配置事务管理器 -->    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">        <!-- 注入 sessionFactory-->        <property name="sessionFactory" ref="sessionFactory"/>    </bean>    <tx:annotation-driven transaction-manager="transactionManager"/>

（五）创建bean

<bean id="baseDao" abstract="true">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean><!-- 引入外部sprign配置文件 -->    <import resource="classpath:cn/itcast/shop/*/conf/*-spring.xml"/>

5.创建项目中总struts2配置文件

<!-- 禁用动态方法访问 -->    <constant name="struts.enable.DynamicMethodInvocation" value="false" />    <!-- 配置成开发模式 -->    <constant name="struts.devMode" value="true" />    <!-- 配置拓展名为action -->    <constant name="struts.action.extention" value="action" />    <!-- 把主题配置成simple -->    <constant name="struts.ui.theme" value="simple" />

再次将子配置文件添加进来

<!-- 包含struts配置文件 -->    <include file="cn/itcast/shop/index/conf/index-struts.xml"></include>

6.创建实体类entity包下的user类

public class User implements Serializable{    private Integer uid ;    private String username;    private String password;    private String name;    private String email;    private String phone;    private String addr;    private String sex;    public Integer getUid() {        return uid;    }    public void setUid(Integer uid) {        this.uid = uid;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    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 getPhone() {        return phone;    }    public void setPhone(String phone) {        this.phone = phone;    }    public String getAddr() {        return addr;    }    public void setAddr(String addr) {        this.addr = addr;    }    public String getSex() {        return sex;    }    public void setSex(String sex) {        this.sex = sex;    }}

7.创建entity下的User.hbm.xml的配置文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="cn.itcast.shop.user.entity.User" table="user">        <!-- 配置唯一标识 -->        <id name="uid" column="uid">            <generator class="native"/>        </id>        <!-- 配置普通属性 -->        <property name="username" column="username"/>        <property name="password" column="password"/>        <property name="name" column="name"/>        <property name="email" column="email"/>        <property name="phone" column="phone"/>        <property name="addr" column="addr"/>        <property name="sex" column="sex"/>    </class></hibernate-mapping>

8.抽取以BaseDao和BaseService为名的核心代码

①BaseDao

public interface BaseDao<T> {    //新增    public void save(T entity);    //更新    public void update(T entity);    //根据id删除    public void deleteById(Serializable id);    //根据id查找    public T findObjectById(Serializable id);    //查找列表    public List<T> findObjects();}

②BaseDaoImpl

public class BaseDaoImpl<T> extends HibernateDaoSupport implements BaseDao<T> {    Class<T> clazz;    public BaseDaoImpl(){        ParameterizedType pt = (ParameterizedType)this.getClass().getGenericSuperclass();        clazz = (Class<T>)pt.getActualTypeArguments()[0];    }    @Override    public void save(T entity) {        // TODO Auto-generated method stub        getHibernateTemplate().save(entity);    }    @Override    public void update(T entity) {        // TODO Auto-generated method stub        getHibernateTemplate().update(entity);    }    @Override    public void deleteById(Serializable id) {        // TODO Auto-generated method stub        getHibernateTemplate().delete(findObjectById(id));    }    @Override    public T findObjectById(Serializable id) {        // TODO Auto-generated method stub        return getHibernateTemplate().get(clazz, id);    }    @Override    public List<T> findObjects() {        // TODO Auto-generated method stub        Query query = getSession().createQuery("FROM "+clazz.getSimpleName());        return query.list();    }}

③BaseService

public interface BaseService<T> {    //新增    public void save(T entity);    //更新    public void update(T entity);    //根据id删除    public void deleteById(Serializable id);    //根据id查找    public T findObjectById(Serializable id);    //查找列表    public List<T> findObjects();}

④BaseServiceImpl

public class BaseServiceImpl<T> implements BaseService<T> {    private BaseDao<T> baseDao;    public void setBaseDao(BaseDao<T> baseDao) {        this.baseDao = baseDao;    }    @Override    public void save(T entity) {        // TODO Auto-generated method stub        baseDao.save(entity);    }    @Override    public void update(T entity) {        // TODO Auto-generated method stub        baseDao.update(entity);    }    @Override    public void deleteById(Serializable id) {        // TODO Auto-generated method stub        baseDao.deleteById(id);    }    @Override    public T findObjectById(Serializable id) {        // TODO Auto-generated method stub        return baseDao.findObjectById(id);    }    @Override    public List<T> findObjects() {        // TODO Auto-generated method stub        return baseDao.findObjects();    }}

9.使用具体的业务代码继承上述的核心代码
①UserDao

public interface UserDao extends BaseDao<User> {    public User findUserByAccountAndPassword(String username, String password);}

②UserDaoImpl

public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao {}

③UserService

public interface UserService extends BaseService<User>{}

④UserSericeImpl

@Service("userService")public class UserServiceImpl extends BaseServiceImpl<User> implements UserService {    private UserDao userDao ;    @Resource    public void setUserDao(UserDao userDao) {        super.setBaseDao(userDao);        this.userDao = userDao;    }}

10.编写action代码

public class UserAction extends ActionSupport {    @Resource    private UserService userService ;    private User user ;     //跳转到注册页面    public String registerPage(){        return "registerPageSuccess";    }    //实行注册功能    public String register(){        userService.save(user);        return "registerSuccess";    }    //跳转到登陆页面    public String loginPage(){        return "loginPageSuccess";    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }}

11.配置子配置文件user-struts和user-spring文件
①user-struts

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"    "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <package name="user-action" namespace="/user" extends="struts-default">        <action name="user_*" class="userAction" method="{1}">            <result name="registerPageSuccess">/WEB-INF/jsp/user/register.jsp</result>            <result name="registerSuccess">>/WEB-INF/jsp/index/success.jsp</result>                 </action>    </package></struts>

@user-spring文件

<?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:context="http://www.springframework.org/schema/context"    xmlns:aop="http://www.springframework.org/schema/aop" 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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <bean id="userAction" class="cn.itcast.shop.user.action.UserAction"></bean>    <bean id="userDao" class="cn.itcast.shop.user.dao.impl.UserDaoImpl" parent="baseDao"></bean>    <!-- 扫描service -->    <context:component-scan base-package="cn.itcast.shop.user.service.impl"></context:component-scan></beans>

最最后———————————————-

配置文件的注解和xml配置的区分：
注解：

<!-- 扫描service -->    <context:component-scan base-package="cn.itcast.shop.user.service.impl"></context:component-scan>

那么就无需在xml 文件中创建bean，只需在service类上注入就行

@Service("userService")    public class UserServiceImpl extends BaseServiceImpl<User> implements UserService {    }

同时用@Resource进行属性的装配

@Resource    private UserDao userDao ;

xml配置：

<!-- 配置Dao================================== -->    <bean id="userDao" class="cn.itcast.shop.user.UserDao">        <property name="sessionFactory" ref="sessionFactory"/>    </bean><!-- 配置Service================================== -->    <bean id="userService" class="cn.itcast.shop.user.UserService">        <property name="userDao" ref="userDao"/>    </bean><!-- 配置Action================================== -->    <bean id="userAction" class="cn.itcast.shop.user.UserAction" scope="prototype">        <property name="userService" ref="userService"/>    </bean>

那么在实际代码中需

// 注入Dao    private UserDao userDao;    public void setUserDao(UserDao userDao) {        this.userDao = userDao;    }
