Spring MVC与Mongodb整合开发实例

Spring MVC与MongoDB整合开发实例：

1、mongodb层

package com.zhao.sys.mongodb;

import com.zhao.sys.domain.User;
/**
 * System - 用户 - mongo层
 * 
 * @author Dwen
 * @version v 0.1 2013-3-19 下午03:38:04
 */
public interface IUserMongo {

    /**
     * 用户登录
     * @param user
     * @return
     */
    public User login(User user);
    
    
}

 

package com.zhao.sys.mongodb.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Repository;

import com.zhao.sys.domain.User;
import com.zhao.sys.mongodb.IUserMongo;
@Repository
public class UserMongoImpl implements IUserMongo {

    @Autowired
    private MongoTemplate mongoTemplate;

    /** 用户登录 **/
    public User login(User user) {
        return  mongoTemplate.findOne(new Query(Criteria.where("userName").is(user.getUserName())), User.class,"User");
    }
   
}

 

2、Service层

package com.zhao.sys.service;

import com.zhao.sys.domain.User;
/**
 * System - 用户 - Service层
 * 
 * @author Dwen
 * @version v 0.1 2013-3-19 下午03:38:30
 */
public interface IUserService {

    /**
     * 用户登录
     * @param user
     * @return
     */
    public User login(User user);
}

 

package com.zhao.sys.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.zhao.sys.domain.User;
import com.zhao.sys.mongodb.impl.UserMongoImpl;
import com.zhao.sys.service.IUserService;
@Service
public class UserServiceImpl implements IUserService {

    @Autowired
    private UserMongoImpl userMongo;
    
    /**
     * 用户登录
     * @param user
     * @return
     */
    public User login(User user) {
        User user2 = userMongo.login(user);
        return user2;
    }
}

 

3、Controller层

package com.zhao.sys.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.zhao.sina.weibo4j.util.WeiboConfig;
import com.zhao.sys.domain.User;
import com.zhao.sys.service.impl.UserServiceImpl;

/**
 * System - 用户 - Controller
 * @author Dwen
 * @version v 0.1 2013-3-17 下午09:00:05
 */
@Controller
public class UserController extends BaseController{
    @Autowired
    private UserServiceImpl userService;

    /**
     * 登录
     */
    @RequestMapping("/login")
    public ModelAndView login(HttpServletRequest request,User user){
        User user2 = userService.login(user);
        ModelAndView mav = new ModelAndView();
        if (null==user2) {
            mav.setViewName("sys/index");
        }else{
            mav.addObject("user", user2);
            mav.setViewName("sys/marketing");
        }
        return mav;
    }
}

 

 4、web.xml配置 (该文件放在工程的WEB-INF下)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
	
    <display-name>Spring3MVC</display-name>
 	<servlet>
        		<servlet-name>spring</servlet-name>
	        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	        <load-on-startup>1</load-on-startup>
	 </servlet>
	 
	 <servlet-mapping>
	        <servlet-name>spring</servlet-name>
        		<url-pattern>*.html</url-pattern>
     </servlet-mapping>
	 
	<welcome-file-list>
	        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

 

5、spring-servlet.xml (该文件放在工程的WEB-INF下)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	 	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	 	xmlns:p="http://www.springframework.org/schema/p"
	 	xmlns:mongo="http://www.springframework.org/schema/data/mongo"
	 	xmlns:context="http://www.springframework.org/schema/context"
	 	xsi:schemaLocation="http://www.springframework.org/schema/beans
	  	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
	  	http://www.springframework.org/schema/data/mongo  
         http://www.springframework.org/schema/data/mongo/spring-mongo.xsd
  		http://www.springframework.org/schema/context
  		http://www.springframework.org/schema/context/spring-context-3.0.xsd">
	   
    <!-- sys Module-->
    <context:component-scan base-package="com.zhao.sys.mongodb" />
    <context:component-scan base-package="com.zhao.sys.service" />
	<context:component-scan base-package="com.zhao.sys.controller" />

	 <bean id="viewResolver"
	  class="org.springframework.web.servlet.view.UrlBasedViewResolver">
	  <property name="viewClass"
	   value="org.springframework.web.servlet.view.JstlView" />
	  <property name="prefix" value="/WEB-INF/views/" />
	  <property name="suffix" value=".jsp" />
	 </bean>
	 
	<mongo:mongo host="localhost" port="27017"></mongo:mongo>
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">  
    		<constructor-arg ref="mongo"/>  
    		<constructor-arg name="databaseName" value="test"/>  
  	</bean>  
</beans>
