第一步：导包

写一个映射文件以及实体类

package oyb.domain;

public class User {
    private Integer id;
    private String username;
    private String password;

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = 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 Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username=‘" + username + ‘\‘‘ +
                ", 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">

dao层

package oyb.dao;

import oyb.domain.User;

public interface IUserDao {
    public void save(User user);
}

package oyb.dao.impl;

import org.springframework.orm.hibernate3.HibernateTemplate;
import oyb.dao.IUserDao;
import oyb.domain.User;

public class UserDaoImpl implements IUserDao {
    //停供set方法由spring注入
    private HibernateTemplate hibernateTemplate;

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }

    @Override
    public void save(User user) {
        this.hibernateTemplate.save(user);
    }
}

service层

package oyb.service;

import oyb.domain.User;

public interface IUserService {
    public void save(User user);
}

package oyb.service.impl;

import oyb.dao.IUserDao;
import oyb.domain.User;
import oyb.service.IUserService;

public class UserService implements IUserService {
    private IUserDao userDao;

    public void setUserDao(IUserDao userDao) {
        this.userDao = userDao;
    }

    @Override
    public void save(User user) {
        userDao.save(user);
    }
}

hibernate的配置文件

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

        <!-- 配置JavaBean与表的映射文件 -->
        <mapping resource="oyb/domain/User.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

applicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!--xmlns xml namespace:xml命名空间-->

单元测试类

package oyb.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 oyb.domain.User;
import oyb.service.IUserService;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class test {
    @Autowired
    private IUserService userService;

    @Test
    public  void test(){
        User user = new User();
        user.setUsername("oyb");
        userService.save(user);
    }

}

运行之后的结果：

但是查看数据库并没有数据

技术图片

原因是因为保存用户是要提交事务的，所以还需在Spring里配置hibernate的事务管理器

在applicationContxt配置事务

<!--配置事务-->
    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <!--配置事务详情-->
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="save"/>
        </tx:attributes>
    </tx:advice>

    <!--AOP编程-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* oyb.service..*.*(..))"></aop:advisor>
    </aop:config>

整合Struts

编写UserAction

package oyb.action;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import oyb.domain.User;
import oyb.service.IUserService;

public class UserAction extends ActionSupport implements ModelDriven<User> {
   private User user =new User();
    //默认会根据名称自动注入
    /**
     * 在action中使用Service注意：
     * 1.不需要在spring的配置文件中注入service
     * 2.会根据spring中的id的名字注入到当前属性中
     * 3.在action中service要提供set方法
     */
    private IUserService userService;

    public void setUserService(IUserService userService) {
        this.userService = userService;
    }
    public String save(){
        //实际开发中这里接收参数
       
        System.out.println(user);
        userService.save(user);
        return SUCCESS;
    }
    @Override
    public User getModel() {
        return user;
    }
}

配置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">
