基于annotation的struts1.3+hibernate3.3+spring2.5

今天弄了一天，查了N次资料和baidu，终于做出来啦。自己被自己感动了。学习中，大家都别笑话。

实体类：

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
@Table(name="user")
public class User {
	@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
	private int id; 
	@Column(name="name",length=15)
	private String name;
	@Column(name="password",length=15)
	private String password;
	
	public User(){
		
	}
	
	public User(String name, String password) {
		this.name = name;
		this.password = password;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
}

DAO层的接口与实现类：

import com.iesgroup.annotation.entity.User;

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

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import com.iesgroup.annotation.dao.UserDao;
import com.iesgroup.annotation.entity.User;

@Repository
public class UserDaoImpl  implements UserDao {
	
	@Resource private SessionFactory sessionFactory;

	public void save(User user) {
//		sessionFactory.getCurrentSession().persist(user);
		sessionFactory.openSession().save(user);
	}
}

这里的实现类在使用annotation的时候，最好不要给它起别名，UserDaoImpl的类名字只能是默认的userDaoImpl。否则的话会出现此bean无法创建的错误。

service层的接口与实现类
[

import com.iesgroup.annotation.entity.User;

public interface UserService {
	public void addUser(User user);
}

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.iesgroup.annotation.dao.UserDao;
import com.iesgroup.annotation.entity.User;
import com.iesgroup.annotation.service.UserService;

@Service
@Transactional(propagation=Propagation.SUPPORTS)
public class UserServiceImpl implements UserService {

@Resource private UserDao userDao;

// @Transactional(propagation=Propagation.REQUIRES_NEW)
public void addUser(User user) {
userDao.save(user);
}

}
form:

import org.apache.struts.action.ActionForm;

public class UserForm extends ActionForm {
	private int id;
	private String name;
	private String password;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
}

action:

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.MappingDispatchAction;
import org.springframework.stereotype.Controller;

import com.iesgroup.annotation.entity.User;
import com.iesgroup.annotation.form.UserForm;
import com.iesgroup.annotation.service.UserService;

@Controller("/add")
public class UserAction extends MappingDispatchAction {

	@Resource private UserService userService;
	
	public ActionForward add(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		UserForm userForm = (UserForm)form;
		User user = new User(userForm.getName(),userForm.getPassword());
		userService.addUser(user);
		return mapping.findForward("success");
	}
	
}

spring中配置数据源以及hibernate的一些配置项

这两天找了很久都没找到好的资料，自己把已有的一次资料整理了一下，做了出来，给正在寻找的朋友留个低而已。
只是把流程过了一遍而已，有什么不对的地方请大家多指教。
