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);
}

}

报错问题：userService 不能实例话

Error creating bean with name 'userService' defined in

ServletContext resource [/WEB-INF/SpringhibernateStudy-servlet.xml]: Initialization of bean failed; nested exception is

org.aopalliance.aop.AspectException: null
java.lang.IllegalStateException: Unknown callback class

[lxxstarii]

我已经帮你解决了，给我分：）

[5iasp]

问题已解决

[lxxstarii]

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>

[lxxstarii]

把public class UserServiceImp

改为
public class UserServiceImp implements UserService
