Spring+MongoDB实现登录注册功能

这篇文章主要为大家详细介绍了Spring+MongoDB实现登录注册功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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.jspspringorg.springframework.web.servlet.dispatcherServletcontextConfigLocationclasspath:applicationContext.xmlspring/encodingorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8encoding*.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; } }
