搭建SpringMVC+Mybatis框架并实现数据库的操作

User类

public class User {
private Integer id;
private String userName;
private String password;
private String tel;
private String email;
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Integer getId() {
return id;
}
public void setId(Integer 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;
}

}

dao

public interface UserMapper {
public List<User> getUserList();
public User getUser(User user);
public int insertUser(User user);
public int deleteUser(User user);
public int updateUser(User user);

}

mybatis的映射

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="org.project.dao.user.UserMapper">

<!-- getUserList -->
<select id="getUserList" resultType="user" parameterType="user">
select * from user order by id desc
</select>

<!-- getUser -->
<select id="getUser" resultType="user" parameterType="user">
select * from user where username = #{userName} and password = #{password}
</select>

<!-- insertUser -->
<insert id="insertUser" parameterType="user">
insert into user (username,password,tel,email) values (
#{userName},#{password},#{tel},#{email}
)
</insert>

<!-- deleteUser -->
<delete id="deleteUser" parameterType="user">
delete from user where id = #{id}
</delete>

<!-- updateUser -->
<update id="updateUser" parameterType="user">
update user set password = #{password}, tel = #{tel}, email = #{email}
where id = #{id}
</update>
</mapper>

service

public interface UserService {
/**
* getUserList
* @return
*/
public List<User> getUserList();
/**
* getUser
* @param user
* @return user
*/
public User getUser(User user);
/**
* insertUser
* @param user
* @return int
*/
public int insertUser(User user);
/**
* deleteUser
* @param user
* @return int
*/
public int deleteUser(User user);
/**
* updateUser
* @param user
* @return int
*/
public int updateUser(User user);
}

service实现类（注解的方式）

@Service
public class UserServiceImpl implements UserService {

@Resource
private UserMapper mapper;

public int deleteUser(User user) {
// TODO Auto-generated method stub
return mapper.deleteUser(user);
}

public User getUser(User user) {
// TODO Auto-generated method stub
return mapper.getUser(user);
}

public List<User> getUserList() {
// TODO Auto-generated method stub
return mapper.getUserList();
}

public int insertUser(User user) {
// TODO Auto-generated method stub
return mapper.insertUser(user);
}

public int updateUser(User user) {
// TODO Auto-generated method stub
return mapper.updateUser(user);
}

}

控制器

@Controller //类似Struts的Action
public class IndexController {
private Logger loger = Logger.getLogger(IndexController.class);
@Resource
private UserService userService;

@RequestMapping("/index.html")  // 请求url地址映射，类似Struts的action-mapping
public String index() {
loger.debug("IndexController index.userService:" +userService );
return "index";
}
@RequestMapping("/register.html")
public String register(){
return "register";
}
@RequestMapping("/exit.html")  // 请求url地址映射，类似Struts的action-mapping
public String exit() {
loger.debug("IndexController exit.");
return "exit";
}
@RequestMapping("/login.html")
public String login(){
return "login";
}
@RequestMapping("/loginsuccess.html")  // 请求url地址映射，类似Struts的action-mapping
public ModelAndView  loginsuccess(User user) {
loger.debug("IndexController login.username : " + user.getUserName()
+ " --- password:"+user.getPassword());

user = userService.getUser(user);

loger.debug("select username : " + user.getUserName()
+ " --- password:"+user.getPassword());
return new ModelAndView("loginsuccess");
}

@RequestMapping("/regsuccess.html")
public ModelAndView regsuccess(User user){
loger.debug("IndexController register.username : " + user.getUserName()
+ "---- password: " + user.getPassword());
int f = userService.insertUser(user);
if(f > 0){
user = userService.getUser(user);
}
return new ModelAndView("regsuccess");
}

}

mybatis的配置文件

<!DOCTYPE configuration
