ssh2项目搭建注解形式

1.加入spring-hibernate-struts2JAR包


2.Userinfo.java:


package com.ruicaiedu.test.domain;


import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;


import org.springframework.stereotype.Component;


@Component("userinfo")//相当于实例化userinfo，可不写
@Entity//代替hibernate映射文件的class
public class Userinfo implements java.io.Serializable{


/**
* 
*/
private static final long serialVersionUID = 1L;
@Id
private String userid;
private String userpwd;
private int userage;
//@OneToMany("students")关联的话这样写
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getUserpwd() {
return userpwd;
}
public void setUserpwd(String userpwd) {
this.userpwd = userpwd;
}
public int getUserage() {
return userage;
}
public void setUserage(int userage) {
this.userage = userage;
}


}
-----------------------------------------------------
3.UserinfoDao：


package com.ruicaiedu.test.dao;


import java.util.List;


import com.ruicaiedu.test.domain.Userinfo;


public interface UserinfoDao {
public void saveUserinfo(Userinfo userinfo);

public void deleteUserinfo(Userinfo userinfo);

public void updateUserinfo(Userinfo userinfo);

public Userinfo getUserinfo(Userinfo userinfo);

public List<Userinfo> getUserinfos();
}
----------------------------------------------------------
4.UserinfoImpl：


package com.ruicaiedu.test.impl;


import java.util.List;


import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;


import com.ruicaiedu.test.dao.UserinfoDao;
import com.ruicaiedu.test.domain.Userinfo;


@Repository("userinfoDao")//持久层实例化，相当于@Component
public class UserinfoImpl implements UserinfoDao {
private Session session = null;
@Autowired//相当于DI注入
private SessionFactory sessionFactory;


public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}


@Override
public void saveUserinfo(Userinfo userinfo) {
session = sessionFactory.getCurrentSession();
session.save(userinfo);
}


@Override
public void deleteUserinfo(Userinfo userinfo) {
session = sessionFactory.getCurrentSession();
session.delete(userinfo);
}


@Override
public void updateUserinfo(Userinfo userinfo) {
session = sessionFactory.getCurrentSession();
session.update(userinfo);


}


@Override
public Userinfo getUserinfo(Userinfo userinfo) {
session = sessionFactory.getCurrentSession();
Query query = session
.createQuery("from Userinfo where Userinfo.userid=?");
query.setString(0, userinfo.getUserid());
return (Userinfo) query.uniqueResult();
}


@Override
public List<Userinfo> getUserinfos() {
session = sessionFactory.getCurrentSession();
Query query = session.createQuery("from Userinfo");
return query.list();
}


}
--------------------------------------------------------
5.UserinfoService：


package com.ruicaiedu.test.service;


import java.util.List;


import com.ruicaiedu.test.domain.Userinfo;




public interface UserinfoService {
public void saveUserinfo(Userinfo userinfo);


public void deleteUserinfo(Userinfo userinfo);


public void updateUserinfo(Userinfo userinfo);


public Userinfo getUserinfo(Userinfo userinfo);


public List<Userinfo> getUserinfos();
}
-----------------------------------------------------------------
6.UserinfoServiceImpl：


package com.ruicaiedu.test.serviceImpl;


import java.util.List;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;


import com.ruicaiedu.test.dao.UserinfoDao;
import com.ruicaiedu.test.domain.Userinfo;
import com.ruicaiedu.test.service.UserinfoService;


@Service("userinfoService")//业务层实例化，相当于@Component
public class UserinfoServiceImpl implements UserinfoService{
@Autowired//相当于DI注入
private UserinfoDao userinfoDao;

public void setUserinfoDao(UserinfoDao userinfoDao) {
this.userinfoDao = userinfoDao;
}


@Transactional(propagation=Propagation.REQUIRED)
@Override
public void saveUserinfo(Userinfo userinfo) {
userinfoDao.saveUserinfo(userinfo);
}


@Transactional(propagation=Propagation.REQUIRED)
@Override
public void deleteUserinfo(Userinfo userinfo) {
userinfoDao.deleteUserinfo(userinfo);

}


@Transactional(propagation=Propagation.REQUIRED)
@Override
public void updateUserinfo(Userinfo userinfo) {
userinfoDao.updateUserinfo(userinfo);

}


@Transactional(propagation=Propagation.NOT_SUPPORTED)
@Override
public Userinfo getUserinfo(Userinfo userinfo) {
return userinfoDao.getUserinfo(userinfo);
}


@Transactional(propagation=Propagation.NOT_SUPPORTED)
@Override
public List<Userinfo> getUserinfos() {
return userinfoDao.getUserinfos();
}


}
-------------------------------------------------------------------------
7.UserinfoAction：


package com.ruicaiedu.test.action;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;


import com.ruicaiedu.test.domain.Userinfo;
import com.ruicaiedu.test.service.UserinfoService;


@Controller("userinfoAction")//实例化控制层，相当于@Component
public class UserinfoAction {
private Userinfo user;
@Autowired//相当于DI注入
private UserinfoService userinfoService;
//这个是spring的di
public void setUserinfoService(UserinfoService userinfoService) {
this.userinfoService = userinfoService;
}


//下面两个是struts2的
public Userinfo getUser() {
return user;
}


public void setUser(Userinfo user) {
this.user = user;
}




//只实现添加
public String saveUserinfo(){
userinfoService.saveUserinfo(user);
return "index";
}


public String updateUserinfo(){
return "index";
}

public String deleteUserinfo(){
return "index";
}

public String getUserinfo(){
return "index";
}
public String getUserinfos(){
return "index";
}
}
-----------------------------------------------------------------------
8.jdbc.properties文件（数据库连接员员）：


jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/jingteng?useUnicode=true&amp;characterEncoding=utf-8
jdbc.username=root
jdbc.password=jingteng
