</beans>

第三步 jdbc.properties属性文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/shop
jdbc.username=root
jdbc.password=admin

第四步 struts.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
    <!-- 修改常量管理struts 中的action的工程，这个常量的使用，必须引入 spring和struts的整合包，
    不然spring无法管理struts2 Action 中的实体类-->
    <constant name="struts.objectFactory" value="spring" />

    <package name="user" extends="struts-default" namespace="/">
        <action name="user_*" class="userAction" method="{1}">

            <result name="success">
                /index.jsp
            </result>

            <!-- struts 2.5 之后，使用通配符必须加上这一行 ，否则无法使用通配符访问-->
            <allowed-methods>m1,saveUser</allowed-methods>
        </action>
    </package>
</struts>

第五步 编写 XxxDao.java

package com.ssh.dao;

import com.ssh.model.User;

public interface UserDao {
     User getUser(Integer uid);

    void saveUser(User user);
}

第六步 编写 XxxDaoImpl.java

package com.ssh.dao;

import com.ssh.model.User;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import javax.annotation.Resource;
@Repository
public class UserDaoImpl implements UserDao{

    /*sessionFactory依赖注入*/
    @Resource(name="sessionFactory")
    private SessionFactory sessionFactory;
    public User getUser(Integer uid) {
        Session session = sessionFactory.getCurrentSession();
        User user = session.get(User.class,uid);
        return user;
    }

    public void saveUser(User user) {
        Session session = sessionFactory.getCurrentSession();
        session.save(user);
        System.out.println("输出："+user.getUsername());
    }
}

第七步 编写 XxxService.java

package com.ssh.service;

import com.ssh.model.User;

public interface UserSerivce {
    User getUser(Integer uid);

    void saveUser(User user);
}

第八步 编写 XxxServiceImpl.java

package com.ssh.service;

import com.ssh.dao.UserDao;
import com.ssh.model.User;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import javax.transaction.Transactional;

@Service("userService")
public class UserServiceImpl implements UserSerivce{

    @Resource
    private UserDao userDao;

    @Transactional(rollbackOn={Exception.class,RuntimeException.class})
    public User getUser(Integer uid) {
        return userDao.getUser(uid);
    }
    @Transactional(rollbackOn = {Exception.class,RuntimeException.class})
    public void saveUser(User user) {
        userDao.saveUser(user);
    }
}

第九步 编写 XxxAction.java

package com.ssh.action;

import com.opensymphony.xwork2.ActionSupport;
import com.ssh.model.User;
import com.ssh.service.UserSerivce;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import javax.annotation.Resource;

@Controller("userAction")
@Scope("prototype")
public class UserAction extends ActionSupport {
    private User user;
    @Resource
    private UserSerivce userService;
    public User getUser() {
        return user;
    }

    public String m1(){
        user =  userService.getUser(1);
        System.out.println(user.getUsername());
        return SUCCESS;
    }

    public String saveUser(){
        User user = new User();

        user.setUsername("事务提交");
        userService.saveUser(user);

        return SUCCESS;
    }
}

第十步 编写model Xxx

package com.ssh.model;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class User {
    private int uid;
    private String username;
    private String password;
    private String name;
    private String email;
    private String phone;
    private String addr;
    private Integer state;
    private String code;

    @Id
    @Column(name = "uid")
    public int getUid() {
        return uid;
    }

    public void setUid(int uid) {
        this.uid = uid;
    }

    @Basic
    @Column(name = "username")
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Basic
    @Column(name = "password")
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Basic
    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Basic
    @Column(name = "email")
    public String getEmail() {

    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Basic
    @Column(name = "phone")
    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    @Basic
    @Column(name = "addr")
    public String getAddr() {
        return addr;
    }

    public void setAddr(String addr) {
        this.addr = addr;
    }

    @Basic
    @Column(name = "state")
    public Integer getState() {
        return state;
    }

    public void setState(Integer state) {
        this.state = state;
    }

    @Basic
    @Column(name = "code")
    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        User user = (User) o;

        if (uid != user.uid) return false;
        if (username != null ? !username.equals(user.username) : user.username != null) return false;

        if (code != null ? !code.equals(user.code) : user.code != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = uid;
        result = 31 * result + (username != null ? username.hashCode() : 0);
        result = 31 * result + (password != null ? password.hashCode() : 0);
        result = 31 * result + (name != null ? name.hashCode() : 0);
        result = 31 * result + (email != null ? email.hashCode() : 0);
