SpringMVC中Bean的配置spring-mvc.xml

Hibernate的配置hibernate.cfg.xml

<?

</hibernate-configuration>

实体层

package com.myweb.entity;
import java.io.Serializable;
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 = "w_user")
public class User implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Column(name = "user_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    @Column(length = 50)
    private String username;
    @Column(length = 20)
    private String password;
    public Integer getId() {
        return id;
    }

    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

数据訪问层（DAO层）

接口：

package com.myweb.dao;
import com.myweb.entity.User;
public interface UserDao {
    User save(User user);
}

实现：

package com.myweb.dao.imp;

import javax.inject.Inject;

import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;

import com.myweb.dao.UserDao;
import com.myweb.entity.User;

@Repository
public class UserDaoImp implements UserDao {
    @Inject
    private HibernateTemplate template;

    @Override
    public User save(User user) {
        // TODO Auto-generated method stub

        template.save(user);

        return template.load(User.class, user.getId());
    }

}

服务层（Service层）

接口：

package com.myweb.service;
import com.myweb.entity.User;
public interface UserService {
    User save(User user);
}

实现：

package com.myweb.service.imp;
import javax.inject.Inject;
import org.springframework.stereotype.Service;
import com.myweb.dao.UserDao;
import com.myweb.entity.User;
import com.myweb.service.UserService;
@Service
public class UserServiceImp implements UserService {
    @Inject
    private UserDao userDao;
    @Override
    public User save(User user) {
        // TODO Auto-generated method stub
        return userDao.save(user);
    }
}

控制层（Controller层）

package com.myweb.controller;
import javax.inject.Inject;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import com.myweb.entity.User;
import com.myweb.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
    @Inject
    private UserService userService;
    @RequestMapping(value = "/register.do", method = RequestMethod.POST)
    public String register(User user) {
        userService.save(user);
        return "login";
    }
    @RequestMapping(value = "/login.do", method = RequestMethod.POST)
    public String login(@ModelAttribute("user") User user) {
        return "self";
    }
}

视图成（View层）

register.jsp
