Spring+MongoDB实现登录注册功能

本文实例为大家分享了Spring，Spring MVC，MongoDB实现登录注册 的具体代码，供大家参考，具体内容如下

工程目录： 

Spring配置文件：

Web.xml:

  
 
 login.jsp
 
 
 
 spring
 org.springframework.web.servlet.DispatcherServlet
 
 contextConfigLocation
 classpath:applicationContext.xml
 
 
 
 spring
 /
 
 
 
 encoding
 org.springframework.web.filter.CharacterEncodingFilter
 
 encoding
 UTF-8
 
 
 
 
 encoding
 *.do
 
 

Model层：

package com.model;

import org.springframework.data.annotation.Id;
import org.springframework.data.document.mongodb.mapping.document;


@document(collection = "p3") 
public class User {
 @Id
 String name;
 String password;
 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;
 }
 
 
 
} 

UserDao:

 package com.userdao;

import com.model.User;

public interface UserDao {
 public void insert(User user);
 public boolean find(String name,String password);
 public void save(User user);
 
 
} 

UserDaoImpl:

package com.userdaoimpl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.document.mongodb.MongoTemplate;
import org.springframework.data.document.mongodb.query.Criteria;
import org.springframework.data.document.mongodb.query.Query;

import com.model.User;
import com.userdao.UserDao;

public class UserDaoImpl implements UserDao{
 
 @Autowired
 MongoTemplate mongoTemplate;
 
 @Override
 public void insert(User user) {
 getMongoTemplate().insert(user);
 
 }
 
 
 
 @Override
 public boolean find(String name, String password) {
 Criteria criteria=Criteria.where("name").is(name).and("password").in(password);
 User user = getMongoTemplate().findOne(new Query(criteria), User.class);
 if (user==null) {
 return false;
 }
 return true;
 }

 @Override
 public void save(User user) {
 getMongoTemplate().save(user);
 
 }


 public MongoTemplate getMongoTemplate() {
 return mongoTemplate;
 }

 public void setMongoTemplate(MongoTemplate mongoTemplate) {
 this.mongoTemplate = mongoTemplate;
 }
 
 
 
} 

LoginController:

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.userdaoimpl.UserDaoImpl;


@Controller
public class LoginController {
 @Autowired
 UserDaoImpl userDaoImpl;
 
 
 @RequestMapping("/login")
 public String login(String name,String password,Model model) {
 boolean rs = userDaoImpl.find(name, password);
 if (rs==true) {
 return "index";
 }
 return "erro";
 
 }


 public UserDaoImpl getUserDaoImpl() {
 return userDaoImpl;
 }


 public void setUserDaoImpl(UserDaoImpl userDaoImpl) {
 this.userDaoImpl = userDaoImpl;
 }
} 

RegisterController:

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.model.User;
import com.userdaoimpl.UserDaoImpl;


@Controller
public class RegisterController {
 @Autowired 
 UserDaoImpl userDaoImpl;
 @RequestMapping("/register")
 public String register(String name,String password,Model model) {
 User user = new User();
 user.setName(name);
 user.setPassword(password);
 userDaoImpl.save(user);
 return "login";
 }
 public UserDaoImpl getUserDaoImpl() {
 return userDaoImpl;
 }
 public void setUserDaoImpl(UserDaoImpl userDaoImpl) {
 this.userDaoImpl = userDaoImpl;
 }
 
 
 
}
