使用MyEclipse搭建Spring+Hibernate环境

1.数据库提前准备好，新建web项目

2.添加mysql的jar包

3.配置spring，右键项目->myeclipse->add spring...选择以下libraries库->下一步->默认即可

4.finish，效果如图

5.myeclipse右上角切换至MyEclipse database

右键左侧空白区域，new

6.填写相应信息->test driver，测试通过，finish即可

7.回到MyEclipse java

8.右键项目，MyEclipse->add hibernate...->默认选中的库即可（注意更改图中部分）

9.next->选择是生成新的配置文件，还是合并到spring中，选择合并

10.选择已有文件

11.next->选择刚刚建立的数据源

12.next->去掉所选部分，finish即可

13.在web.xml中配置信息

contextConfigLocation

classpath:applicationContext.xml


   org.springframework.web.context.ContextLoaderListener

14.使用逆向工程生成映射文件，选中MyEclipse database...右键打开数据源

15.填写相应信息->next，默认即可，next，finish

16.index.jsp

   

   
   
   
   
   
   
   
   
   
   
   
   
   
   

用户名：
密码：

   

 

17.loginservlet

public class LoginServlet extends HttpServlet {


private static final long serialVersionUID = 1L;


Logger logger = Logger.getLogger(LoginServlet.class);

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {


response.setCharacterEncoding("utf-8");
String username = request.getParameter("username");
String password = request.getParameter("password");

Users users = new Users();
users.setName(username);
users.setPwd(password);

users = LoginHelper.getUserService().checkUser(users);

System.out.println(users.getId());

if (users.getId()!=0) {
response.sendRedirect("success.jsp");
}
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doGet(request, response);
}

}

18.loginhelper

public class LoginHelper {

private static UserService userService;

public static UserService getUserService() {
if(userService == null){
userService = (UserService) BeanHelper.get("loginService");
}
return userService;
}     
}

19.beanhelper

public class BeanHelper{


/**

*/
public static WebApplicationContext WEB_APP_CONTEXT = null;

/**

//娴嬭瘯鐢?
CLASS_PATH_XML_APP_CONTEXT = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
}

}

}

20.success.jsp

 
    success
 

21.userservice

public interface UserService {
Users checkUser(Users users);
}

22.userserviceimpl

public class UserServiceImpl implements UserService {
private UserDao userDao;
/**
* @param userDao the userDao to set
*/
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public Users checkUser(Users users) {
// TODO Auto-generated method stub
return userDao.checkUser(users);
}
}

23.userdao

public interface UserDao {
Users checkUser(Users users);
}

24.userdaoimpl

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
public Users checkUser(Users users) {
//return 
List list = this.getHibernateTemplate().find("from com.zym.entity.Users where name=? and pwd=?", users.getName(),users.getPwd());
if (list.size()>0) {
return list.get(0);
}
return null;
}
}

25.web.xml中配置

    LoginServlet
    com.zym.servlet.LoginServlet
 

 
    LoginServlet
    /LoginServlet
 

26.applicationContext.xml文件

xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">






org.hibernate.dialect.MySQLDialect





com/zym/entity/Users.hbm.xml

至此，环境配置以及简单实例到此结束
