整个项目:
3.spring整合hibernate
3.1 po类
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; } @Override public 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层
spring提供 HibernateTemplate 用于操作PO对象,类似Hibernate Session对象
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; //底层需要SessionFactory,自动创建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层
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分两种情况:
一种是有hibernate.cfg.xml
一种没有hibernate.cfg.xml
先说有hibernate配置文件的:
hibernate.cfg.xml文件为:
<?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> <!-- 基本四项 --> <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输出 --> <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> <!-- 绑定线程 --> <property name="hibernate.current_session_context_class">thread</property> <!-- 导入映射文件 --> <mapping resource="com/alice/ssh/domain/User.hbm.xml"/> </session-factory> </hibernate-configuration>
这种情况下,spring配置文件写成如下:
<?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.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 1.加载hibenrate.cfg.xml 获得SessionFactory * configLocation确定配置文件位置 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean> <!-- 2.创建模板 * 底层使用session,session 有sessionFactory获得 --> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 3.dao层 --> <bean id="userDao" class="com.alice.ssh.dao.impl.UserDaoImpl"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> <!--4.service层 --> <bean id="userService" class="com.alice.ssh.service.impl.UserServiceImpl"> <property name="userDao" ref="userDao"></property> </bean> <!-- 5.事务管理 --> <!-- 5.1 事务管理器 :HibernateTransactionManager --> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 5.2 事务详情 ,给ABC进行具体事务设置 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="register"/> </tx:attributes> </tx:advice> <!-- 5.3 AOP编程,ABCD 筛选 ABC --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/> </aop:config> </beans>
无hibernate配置文件的,现在比较常用,这种情况如下配置:
删除hibernate.cfg.xml
在applicationContext.xml中配置相应的文件
<?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.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置数据源 --> <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,获得SessionFactory * configLocation确定配置文件位置 <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> 1)dataSource 数据源 2)hibernateProperties hibernate其他配置项 3) 导入映射文件 mappingLocations ,确定映射文件位置,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 ,加载执行映射文件,从src下开始 。不支持通配符* <property name="mappingResources" value="com/itheima/domain/User.hbm.xml"></property> mappingDirectoryLocations ,加载指定目录下的,所有配置文件 <property name="mappingDirectoryLocations" value="classpath:com/itheima/domain/"></property> mappingJarLocations , 从jar包中获得映射文件 --> <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层 --> <bean id="userDao" class="com.alice.ssh.dao.impl.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!--4.service层 --> <bean id="userService" class="com.alice.ssh.service.impl.UserServiceImpl"> <property name="userDao" ref="userDao"></property> </bean> <!-- 5.事务管理 --> <!-- 5.1 事务管理器 :HibernateTransactionManager --> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 5.2 事务详情 ,给ABC进行具体事务设置 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="register"/> </tx:attributes> </tx:advice> <!-- 5.3 AOP编程,ABCD 筛选 ABC --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/> </aop:config> </beans>
修改dao,使用HibernateDaoSupport
// 底层需要SessionFactory,自动创建HibernateTemplate模板 public class UserDaoImpl extends HibernateDaoSupport implements UserDao { @Override public void save(User user) { this.getHibernateTemplate().save(user); }
测试用例:
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 { @Autowired private UserService userService; @Test public 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创建action
1.编写action类,并将其配置给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 封装数据 private User user = new User(); public User getModel() { return user; } //2 service private UserService userService; public void setUserService(UserService userService) { this.userService = userService; } /** * 注册 * @return */ public String register(){ userService.register(user); return "success"; } }
applicationContex.xml中注入action
2.编写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> <!-- 开发模式 --> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <!-- 底层自动从spring容器中通过名称获得内容, getBean("userAction") --> <action name="userAction_*" class="userAction" method="register"> <result name="success">/success.jsp</result> </action> </package> </struts>
3.表单jsp页面
<form action="${pageContext.request.contextPath}/userAction_register" method="post"> 用户名:<input type="text" name="username"/> <br/> 密码:<input type="password" name="password"/> <br/> 年龄:<input type="text" name="age"/> <br/> <input type="submit" /> </form>
4.web.xml 配置
1.确定配置文件contextConfigLocation
2.配置监听器 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 确定spring xml位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicactionContext.xml</param-value> </context-param> <!-- 2 spring监听器 --> <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创建action
1 删除spring action配置
2 struts <action class="全限定类名">
<struts> <!-- 开发模式 --> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <!-- 底层自动从spring容器中通过名称获得内容, getBean("userAction") --> <action name="userAction_*" class="com.alice.ssh.web.action.UserAction" method="register"> <result name="success">/success.jsp</result> </action> </package> </struts>
