4.Java Code:

(1) Control layer Usercontroller.java

Package Com.ssm.controller;

Import org.springframework.beans.factory.annotation.Autowired;
Import Org.springframework.stereotype.Controller;
Import org.springframework.web.bind.annotation.RequestMapping;
Import Org.springframework.web.bind.annotation.RequestMethod;

Import Com.ssm.dao.UserDao;
Import Com.ssm.model.User;

@Controller
public class Usercontroller {
@Autowired
Private Userdao DAO;
@RequestMapping (value= "/login", method = Requestmethod.post)
public string Login (string name,string password) {
if (Name==null | | password==null) {
return "fail";
}
User user = Dao.finduserbyname (name);
if (User!=null && password.equals (User.getpassword ())) {
Return "Success";
}
return "fail";
}

}

(2) DAO Layer:

① interface

Package Com.ssm.dao;

Import Com.ssm.model.User;
/**
* DAO interface Layer
*/
Public interface Userdao {
/**
* Query user information according to user name
* @param name
* @return
*/
Public User finduserbyname (String name);
}

② Implementation Class

Package Com.ssm.dao;

Import org.springframework.beans.factory.annotation.Autowired;
Import org.springframework.stereotype.Component;

Import Com.ssm.mapper.UserMapper;
Import Com.ssm.model.User;
/**
* DAO Implementation Layer
*/
@Component
public class Userdaoimpl implements userdao{
@Autowired
Private Usermapper Usermapper;
@Override
Public User finduserbyname (String name) {
User user = Usermapper.selectuserbyname (name);
return user;
}

}

(3) Mapping Relationship interface

Package com.ssm.mapper;

Import Com.ssm.model.User;
/**
* Mapper Mapping class
*/
Public interface Usermapper {
Public User selectuserbyname (String name);

}

(4) Entity class

Package Com.ssm.model;
/**
* User Mapping class
*/
public class User {
Private Integer ID;
private String name;
private String password;
Public Integer getId () {
return ID;
}
public void SetId (Integer id) {
This.id = ID;
}
Public String GetName () {
return name;
}
public void SetName (String name) {
THIS.name = name;
}
Public String GetPassword () {
return password;
}
public void SetPassword (String password) {
This.password = password;
}
@Override
public int hashcode () {
final int prime = 31;
int result = 1;
result = Prime * result + ((name = = null)? 0:name.hashcode ());
result = Prime * result
+ ((password = = null)? 0:password.hashcode ());
return result;
}
@Override
public boolean equals (Object obj) {
if (this = = obj)
return true;
if (obj = = null)
return false;
if (GetClass ()! = Obj.getclass ())
return false;
User other = (user) obj;
if (name = = null) {
if (other.name! = null)
return false;
} else if (!name.equals (other.name))
return false;
if (password = = null) {
if (Other.password! = null)
return false;
} else if (!password.equals (Other.password))
return false;
return true;
}

}
