3.spring整合hibernate

3.1 po類

package com.alice.ssh.domain;public class User {private Integer id;private String username;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}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 Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}@Overridepublic String toString() {return "User [id=" + id + ", username=" + username + ", password="+ password + ", age=" + age + "]";}} <?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 package="com.alice.ssh.domain"><class name="User" table="t_user"><id name="id"><generator class="native"></generator></id><property name="username" type="string"></property><property name="password" type="string"></property><property name="age" ></property></class></hibernate-mapping>

3.2 dao層

spring提供 HibernateTemplate 用于操作PO對象，類似Hibernate Session對象

package com.alice.ssh.dao;import com.alice.ssh.domain.User;public interface IUserDao {public void save(User user); } package com.alice.ssh.dao.impl;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.alice.ssh.dao.IUserDao; import com.alice.ssh.domain.User;//底層需要SessionFactory，自動創建HibernateTemplate模板 public class UserDaoImpl extends HibernateDaoSupport implements IUserDao{// private HibernateTemplate hibernateTemplate;// public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { // this.hibernateTemplate = hibernateTemplate; // }public void save(User user) {this.getHibernateTemplate().save(user);System.out.println("dao+"+user);}}

?

?3.3 service層

package com.alice.ssh.service;import com.alice.ssh.domain.User;public interface UserService {public void register(User user);} package com.alice.ssh.service.impl;import com.alice.ssh.dao.IUserDao; import com.alice.ssh.domain.User; import com.alice.ssh.service.UserService;public class UserServiceImpl implements UserService{private IUserDao userDao;public void setUserDao(IUserDao userDao) {this.userDao = userDao;}public void register(User user) {userDao.save(user);System.out.println("service+"+user);}}

spring整合hibernate分兩種情況：

一種是有hibernate.cfg.xml

一種沒有hibernate.cfg.xml

先說有hibernate配置文件的：

?

?hibernate.cfg.xml文件為：

<?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><!-- 基本四項 --><property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property><property name="hibernate.connection.url">jdbc:mysql://localhost:3306/spring</property><property name="hibernate.connection.username">root</property><property name="hibernate.connection.password">alice</property><!-- 配置方言 --><property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property><!-- sql輸出 --><property name="hibernate.show_sql">true</property><property name="hibernate.format_sql">true</property><!-- 自生成表格 --><property name="hibernate.hbm2ddl.auto">update</property><!-- 綁定線程 --><property name="hibernate.current_session_context_class">thread</property><!-- 導入映射文件 --><mapping resource="com/alice/ssh/domain/User.hbm.xml"/></session-factory></hibernate-configuration>

這種情況下，spring配置文件寫成如下：

<?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: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.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 1.加載hibenrate.cfg.xml 獲得SessionFactory * configLocation確定配置文件位置--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean><!-- 2.創建模板 * 底層使用session，session 有sessionFactory獲得 --> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"><property name="sessionFactory" ref="sessionFactory"></property> </bean><!-- 3.dao層 --> <bean id="userDao" class="com.alice.ssh.dao.impl.UserDaoImpl"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean><!--4.service層 --> <bean id="userService" class="com.alice.ssh.service.impl.UserServiceImpl"><property name="userDao" ref="userDao"></property> </bean><!-- 5.事務管理 --> <!-- 5.1 事務管理器 ：HibernateTransactionManager --> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 5.2 事務詳情 ，給ABC進行具體事務設置 --> <tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="register"/></tx:attributes> </tx:advice><!-- 5.3 AOP編程，ABCD 篩選 ＡＢＣ --> <aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/> </aop:config> </beans>

無hibernate配置文件的，現在比較常用，這種情況如下配置：

刪除hibernate.cfg.xml

在applicationContext.xml中配置相應的文件

<?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: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.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><!-- 配置數據源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="com.mysql.jdbc.Driver"></property><property name="jdbcUrl" value="jdbc:mysql://localhost:3306/spring"></property><property name="user" value="root"></property><property name="password" value="alice"></property> </bean><!-- 1.3配置 LocalSessionFactoryBean，獲得SessionFactory * configLocation確定配置文件位置<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>1)dataSource 數據源2)hibernateProperties hibernate其他配置項3) 導入映射文件mappingLocations ，確定映射文件位置，需要“classpath:” ,支持通配符 【】<property name="mappingLocations" value="classpath:com/itheima/domain/User.hbm.xml"></property><property name="mappingLocations" value="classpath:com/itheima/domain/*.hbm.xml"></property>mappingResources ，加載執行映射文件，從src下開始 。不支持通配符*<property name="mappingResources" value="com/itheima/domain/User.hbm.xml"></property>mappingDirectoryLocations ，加載指定目錄下的，所有配置文件<property name="mappingDirectoryLocations" value="classpath:com/itheima/domain/"></property>mappingJarLocations ， 從jar包中獲得映射文件 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties"><props><prop key="hibernate.dialec">org.hibernate.dialect.MySQL5Dialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.current_session_context_class">thread</prop></props></property><property name="mappingLocations" value="com/alice/ssh/domain/User.hbm.xml"></property></bean><!-- 3.dao層 --> <bean id="userDao" class="com.alice.ssh.dao.impl.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean><!--4.service層 --> <bean id="userService" class="com.alice.ssh.service.impl.UserServiceImpl"><property name="userDao" ref="userDao"></property> </bean><!-- 5.事務管理 --> <!-- 5.1 事務管理器 ：HibernateTransactionManager --> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 5.2 事務詳情 ，給ABC進行具體事務設置 --> <tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="register"/></tx:attributes> </tx:advice><!-- 5.3 AOP編程，ABCD 篩選 ＡＢＣ --> <aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/> </aop:config> </beans>

? 修改dao，使用HibernateDaoSupport

// 底層需要SessionFactory，自動創建HibernateTemplate模板 public class UserDaoImpl extends HibernateDaoSupport implements UserDao {@Overridepublic void save(User user) {this.getHibernateTemplate().save(user);}

?

?測試用例：

package com.alice.ssh.test;import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alice.ssh.domain.User; import com.alice.ssh.service.UserService;@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:applicactionContext.xml") public class UserTest {@Autowiredprivate UserService userService;@Testpublic void test(){User user = new User();user.setUsername("llili");user.setPassword("124354");user.setAge(18);userService.register(user);}}

4、? struts整合spring

4.1?spring創建action

1.編寫action類，并將其配置給spring ，spring可以注入service

package com.alice.ssh.web.action;import com.alice.ssh.domain.User; import com.alice.ssh.service.UserService; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven;public class UserAction extends ActionSupport implements ModelDriven<User>{/*** */private static final long serialVersionUID = 1L;//1 封裝數據private User user = new User();public User getModel() {return user;}//2 serviceprivate UserService userService;public void setUserService(UserService userService) {this.userService = userService;}/*** 注冊* @return*/public String register(){userService.register(user);return "success";}}

applicationContex.xml中注入action

?

2.編寫struts.xml

<?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><!-- 開發模式 --><constant name="struts.devMode" value="true" /><package name="default" namespace="/" extends="struts-default"><!-- 底層自動從spring容器中通過名稱獲得內容， getBean("userAction") --><action name="userAction_*" class="userAction" method="register"><result name="success">/success.jsp</result></action></package> </struts>

?

3.表單jsp頁面

<form action="${pageContext.request.contextPath}/userAction_register" method="post">用戶名：<input type="text" name="username"/> <br/>密碼：<input type="password" name="password"/> <br/>年齡：<input type="text" name="age"/> <br/><input type="submit" /></form>

?

4.web.xml 配置

?????? 1.確定配置文件contextConfigLocation

?????? 2.配置監聽器 ContextLoaderListener

?????? 3.配置前端控制器 StrutsPrepareAndExecuteFitler

?

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><display-name></display-name> <!-- 1 確定spring xml位置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicactionContext.xml</param-value></context-param><!-- 2 spring監聽器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 3 struts 前端控制器 --><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><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list> </web-app>

4.2?struts創建action

1? 刪除spring action配置

?

2 struts <action class="全限定類名">

<struts><!-- 開發模式 --><constant name="struts.devMode" value="true" /><package name="default" namespace="/" extends="struts-default"><!-- 底層自動從spring容器中通過名稱獲得內容， getBean("userAction") --><action name="userAction_*" class="com.alice.ssh.web.action.UserAction" method="register"><result name="success">/success.jsp</result></action></package> </struts>
