1 楼5iasp（aspboy）回复于 2006-06-02 16:55:08 得分 0
相关代码如下：
具体代码有如下类：
User.java:值对象
UserDAO.java dao接口
UserDAOImp dao接口实现类
UserService service接口
UserServiceImp service接口实现类
UserController 控制器类,在这里调用业务逻辑。
代码如下：
1. User.java
package apps.hibernatetest.ioc;
public class User implements java.io.Serializable
{
private String id;
private String username;
private String password;
public User(){}
public String getId()
{
return id;
}
public void setId(String id)
{
this.id = id;
}
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
}
2. UserDAO.java
package apps.hibernatetest.ioc;
public interface UserDAO
{
public void userAdd(User user);
}
3.UserDAOImp.java
package apps.hibernatetest.ioc;
import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Query;
import net.sf.hibernate.Session;
import org.springframework.orm.hibernate.HibernateCallback;
import org.springframework.orm.hibernate.support.HibernateDaoSupport;
public class UserDAOImp extends HibernateDaoSupport implements UserDAO
{
public void userAdd(User user)
{
try
{
System.out.println("save="+getHibernateTemplate().save(user));
getHibernateTemplate().save(user);
}
catch(Exception e)
{
System.out.println("执行插入用户错误！");
}
}
}
4. UserService.java
package apps.hibernatetest.ioc;
public interface UserService
{
public void userAdd(User user);
}
5.UserServiceImp.java
package apps.hibernatetest.ioc;
public class UserServiceImp
{
private UserDAO userDAO;
private User user = new User();
public UserDAO getUserDAO()
{
return userDAO;
}
public void setUserDAO(UserDAO userDAO)
{
this.userDAO = userDAO;
}
public void userAdd(User user)
{
userDAO.userAdd(user);
}
}
6.UserController.java
package apps.hibernatetest.ioc;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.*;
import javax.servlet.http.*;
import org.springframework.web.bind.RequestUtils;
import java.io.IOException;
import java.util.Map;
import java.util.*;
import java.util.HashMap;
import org.apache.commons.beanutils.BeanUtils;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
public class UserController implements Controller
{
private UserService userService;
public void setUserService(UserService userService)
{
this.userService = userService;
}
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException,
IOException
{
String url="";
url="test.jsp";
User u=new User();
u.setUsername("11111");
u.setPassword("1111");
userService.userAdd(u);
return new ModelAndView(url);
}
}

把public class UserServiceImp
改为
public class UserServiceImp implements UserServiceTop
