3. 新建applicationContext.xml
<?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:context="http://www.springframework.org/schema/context" 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/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 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <context:component-scan base-package="com.lq" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="jdbc:mysql://127.0.0.1:3306/test"> </property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <prop key="hibernate.show_sql"> true </prop> </props> </property> <property name="mappingResources"> <list> <value>hbm/User.hbm.xml</value> </list> </property> </bean> <!-- 配置事務管理器（採用註解的方式） --> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 開啟註解事務 --> <tx:annotation-driven transaction-manager="txManager" /> </beans>
4. web.xml配置spring監聽器和struts2過濾器
<!-- 配置Spring的監聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 指定Spring配置檔案所在路徑 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 配置Struts2過濾器 --> <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>
5.新建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>
<constant name="struts.devMode" value="false" />
<!-- <constant name="struts.objectFactory" value="spring" /> -->
<package name="default" namespace="/" extends="struts-default">
<action name="user" class="com.lq.action.UserAction">
<result name="success">/index.jsp</result>
</action>
</package>
</struts>6.建立action
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import com.lq.model.User;
import com.lq.service.IUserService;
import com.opensymphony.xwork2.ActionSupport;
@Controller
public class UserAction extends ActionSupport{
private User user;
@Autowired
private IUserService userService;
@Override
public String execute() throws Exception {
userService.login();
return "success";
}
public IUserService getUserService() {
return userService;
}
public void setUserService(IUserService userService) {
this.userService = userService;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}7.建立service
public interface IUserService {
public boolean login();
}
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.lq.dao.UserDao;
/**
*
* @author haowl
*@Transactional 可以作用於介面、介面方法、類以及類方法上。當作用於類上時，
* 該類的所有 public 方法將都具有該型別的事務屬性
* 該屬性用於設定需要進行回滾的異常類陣列，當方法中丟擲指定異常陣列中的異常時，則進行事務回滾。例如：
指定單一異常類：@Transactional(rollbackFor=RuntimeException.class)
指定多個異常類：@Transactional(rollbackFor={RuntimeException.class, Exception.class})
*/
@Service
@Transactional
public class UserServiceImpl implements IUserService{
@Autowired
private UserDao userDao;
@Override
public boolean login() {
return userDao.login();
}
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
}8.建立dao
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import com.lq.model.User;
@Repository
public class UserDao extends HibernateDaoSupport{
public boolean login() {
Session session =getSessionFactory().openSession();
String sql="select * from tb_users where username=?";
User user = (User)session.createSQLQuery(sql).addEntity(User.class).setParameter(0, "123456").uniqueResult();
System.out.println(user.getLikes());
return false;
}
//按照名稱找到sessionFacotry注入給父類的sessionFacotry屬性
@Resource
public void setSessionFacotry(SessionFactory sessionFacotry) {
super.setSessionFactory(sessionFacotry);
}
}9.建立實體類和與之對應的hbm檔案
public class User implements java.io.Serializable {
private String username;
private String password;
private String email;
private String sex;
private String likes;
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 getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getLikes() {
return likes;
}
public void setLikes(String likes) {
this.likes = likes;
}
}<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
