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：

<beans xmlns="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<!-- 开启自动注入，进行包扫描 -->
<context:component-scan base-package="com" />
<mongo:mongo host="127.0.0.1" port="27017"/>
<!-- 配置MongoTemplate-->
<bean id="mongoTemplate" class="org.springframework.data.document.mongodb.MongoTemplate">
<constructor-arg ref="mongo"/>
<!-- 指定数据库名字-->
<constructor-arg name="databaseName" value="data1"/>
</bean>
<!-- 映射转换器，扫描back-package目录下的文件，根据注释，把它们作为mongodb的一个collection的映射 -->
<mongo:mapping-converter base-package="com.model" />
<!--普通注入-->
<bean id="userDaoImpl" class="com.userdaoimpl.UserDaoImpl">
<property name="mongoTemplate" ref="mongoTemplate"></property>
</bean>
<context:annotation-config />
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<!-- 配置视图解析器，将ModelAndView及字符串解析为具体的页面 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>

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;
}
}
