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;@Repositorypublic 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;@Servicepublic 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 */@Controllerpublic 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"  />  <property name="prefix" value="/WEB-INF/views/" />  <property name="suffix" value=".jsp" /> </bean> <mongo:mongo host="localhost" port="27017"></mongo:mongo>    <bean id="mongoTemplate" value="test"/>    </bean>  </beans>
