2.2、导入spring

spring 添加玩以后，会多出很多的jar 包和一个配置文件 applicationContext.xml

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:p="http://www.springframework.org/schema/p"	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"></beans>

2.3、添加 struts2导入 struts2

2.4、添加 Hibernate

导入hibernate

Hibernate 的配置自动添加到 applicationContext.xml文件中

<!-- 连接池 --><bean id="dataSource"class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName"value="https://tazarkount.com/read/com.mysql.jdbc.Driver"></property><property name="url"value="https://tazarkount.com/read/jdbc:mysql://localhost:3306/myschool"></property><property name="username" value="https://tazarkount.com/read/root"></property><property name="password" value="https://tazarkount.com/read/root"></property></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource"><ref bean="dataSource" /></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop></props></property></bean>

在 applicationContext.xml 中配置事务和支持注解开发

保存，web.xml就配置完了
部署到Tomcat服务器上，无报错，即搭建成功！

2.7、数据编写

建立基本结构
- com.ssh.action
- com.ssh.dao
- com.ssh.pojo
- com.ssh.service
实体类和dao层
实体类

public class Users implements java.io.Serializable {	private Integer uid;	private String uname;	private String usex;	private Timestamp ubirth;//get/set方法，有参无参构造函数，toString();}

? dao层

package com.ssh.dao;import java.sql.Timestamp;import java.util.List;import org.hibernate.LockMode;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.context.ApplicationContext;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.ssh.pojo.Users;public class UsersDAO extends HibernateDaoSupport {private static final Logger log = LoggerFactory.getLogger(UsersDAO.class);// property constantspublic static final String UNAME = "uname";public static final String USEX = "usex";protected void initDao() {// do nothing}public void save(Users transientInstance) {log.debug("saving Users instance");try {getHibernateTemplate().save(transientInstance);log.debug("save successful");} catch (RuntimeException re) {log.error("save failed", re);throw re;}}public void delete(Users persistentInstance) {log.debug("deleting Users instance");try {getHibernateTemplate().delete(persistentInstance);log.debug("delete successful");} catch (RuntimeException re) {log.error("delete failed", re);throw re;}}public Users findById(java.lang.Integer id) {log.debug("getting Users instance with id: " + id);try {Users instance = (Users) getHibernateTemplate().get("com.ssh.pojo.Users", id);return instance;} catch (RuntimeException re) {log.error("get failed", re);throw re;}}public List findByExample(Users instance) {log.debug("finding Users instance by example");try {List results = getHibernateTemplate().findByExample(instance);log.debug("find by example successful, result size: "+ results.size());return results;} catch (RuntimeException re) {log.error("find by example failed", re);throw re;}}public List findByProperty(String propertyName, Object value) {log.debug("finding Users instance with property: " + propertyName+ ", value: " + value);try {String queryString = "from Users as model where model."+ propertyName + "= ?";return getHibernateTemplate().find(queryString, value);} catch (RuntimeException re) {log.error("find by property name failed", re);throw re;}}public List findByUname(Object uname) {return findByProperty(UNAME, uname);}public List findByUsex(Object usex) {return findByProperty(USEX, usex);}public List findAll() {log.debug("finding all Users instances");try {String queryString = "from Users";return getHibernateTemplate().find(queryString);} catch (RuntimeException re) {log.error("find all failed", re);throw re;}}public Users merge(Users detachedInstance) {log.debug("merging Users instance");try {Users result = (Users) getHibernateTemplate().merge(detachedInstance);log.debug("merge successful");return result;} catch (RuntimeException re) {log.error("merge failed", re);throw re;}}public void attachDirty(Users instance) {log.debug("attaching dirty Users instance");try {getHibernateTemplate().saveOrUpdate(instance);log.debug("attach successful");} catch (RuntimeException re) {log.error("attach failed", re);throw re;}}public void attachClean(Users instance) {log.debug("attaching clean Users instance");try {getHibernateTemplate().lock(instance, LockMode.NONE);log.debug("attach successful");} catch (RuntimeException re) {log.error("attach failed", re);throw re;}}public static UsersDAO getFromApplicationContext(ApplicationContext ctx) {return (UsersDAO) ctx.getBean("UsersDAO");}}

Users.hbm.xml
注意：里面的 not null = ‘true’ 需要删除，不然做曾删改时会报错！
如果没删传对象时所有属性都不能为空！

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping><class name="com.ssh.pojo.Users" table="users" catalog="myschool"><id name="uid" type="java.lang.Integer"><column name="uid" /><generator class="identity" /></id><property name="uname" type="java.lang.String"><column name="uname" length="20" /></property><property name="usex" type="java.lang.String"><column name="usex" length="2" /></property><property name="ubirth" type="java.sql.Timestamp"><column name="ubirth" length="19"/></property></class></hibernate-mapping>

编写Service层的接口和实现类
接口

package com.ssh.service;import java.util.List;import com.ssh.pojo.Users;public interface UsersService {	//查询所有用户	List<Users> queryUsersList();//单值查询	Users queryUsers();//添加	void addUsers(Users users);//修改	void updateUsers(Users users);//删除	void delUsers(Users users);}

?实现类

package com.ssh.service;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.transaction.annotation.Transactional;import com.ssh.dao.UsersDAO;import com.ssh.pojo.Users;public class UsersServiceImpl implements UsersService {private UsersDAO usersDAO;public void setUsersDAO(UsersDAO usersDAO) {this.usersDAO = usersDAO;	}//添加	@Autowired	@Transactional	public void addUsers(Users users) {usersDAO.save(users);}//删除	@Autowired	@Transactional	public void delUsers(Users users) {usersDAO.delete(users);}	//单值查询	public Users queryUsers(int uid) {return (Users) usersDAO.findById(uid);	}//查询所有	public List<Users> queryUsersList() {return usersDAO.findAll();	}	//修改	@Autowired//自动装配	@Transactional//开启事务行为，曾删改	public void updateUsers(Users users) {usersDAO.merge(users);}}

编写action层

package com.ssh.action;import java.util.List;import javax.servlet.http.HttpSession;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;import com.ssh.pojo.Users;import com.ssh.service.UsersService;public class UsersAction extends ActionSupport {	private UsersService usersService;private Users users;private List<Users> list;private int uid;//get/set方法public void setUsersService(UsersService usersService) {this.usersService = usersService;	}@Override	public String execute() throws Exception {// TODO Auto-generated method stubreturn super.execute();	}//查询所有用户	public String list() throws Exception {list = usersService.queryUsersList();return "list";}//单值查询	public String query() throws Exception {Users user = usersService.queryUsers(uid);//获取session会话HttpSession session = ServletActionContext.getRequest().getSession();//给session赋值session.setAttribute("user", user);//返回return "query";}	//添加	public String add() throws Exception {usersService.addUsers(users);return list();	}	//删除	public String del() throws Exception {usersService.delUsers(users);return list();	}//修改	public String update() throws Exception {usersService.updateUsers(users);return list();	}}

applicationContext.xml配置
