SpringMVC整合MongoDB

首先，在pom文件中新增spring-data-mongodb的依赖：

<dependency>    <groupId>org.springframework.data</groupId>    <artifactId>spring-data-mongodb</artifactId>    <version>1.8.1.RELEASE</version></dependency>然后，新建spring-mongo.xml

<?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:context="http://www.springframework.org/schema/context"           xmlns:mongo="http://www.springframework.org/schema/data/mongo"           xsi:schemaLocation="http://www.springframework.org/schema/context          http://www.springframework.org/schema/context/spring-context.xsd          http://www.springframework.org/schema/data/mongo          http://www.springframework.org/schema/data/mongo/spring-mongo-1.8.xsd          http://www.springframework.org/schema/beans          http://www.springframework.org/schema/beans/spring-beans.xsd">

<mongo:mongo host="localhost" port="27017"/>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">        <constructor-arg ref="mongo"/>        <constructor-arg name="databaseName" value="test"/>        <!--<constructor-arg ref="userCredentials"/>-->    </bean>

</beans>然后，在Spring的配置文件Spring-context中导入spring-mongo配置文件

<?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:util="http://www.springframework.org/schema/util"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.1.xsd">

   <context:annotation-config />
   <context:component-scan base-package="com.pudp" />    

   <!-- 导入mongodb的配置文件 -->
   <import resource="spring-mongo.xml"/>

</beans>

在model层，新建UserInfo类

@Documentpublic class UserInfo {

private String id;    private String username;    private String nickname;    private String sex;    private String age;

public UserInfo(){}

public UserInfo(String username, String nickname, String sex, String age){        super();        this.username = username;        this.nickname = nickname;        this.sex = sex;        this.age = age;    }

public String getId() {        return id;    }

public void setId(String id) {        this.id = id;    }

public String getUsername() {        return username;    }

public void setUsername(String username) {        this.username = username;    }

public String getNickname() {        return nickname;    }

public void setNickname(String nickname) {        this.nickname = nickname;    }

public String getSex() {        return sex;    }

public void setSex(String sex) {        this.sex = sex;    }

public String getAge() {        return age;    }

public void setAge(String age) {        this.age = age;    }}在DAO层，先新建BaseDao接口

public interface BaseDao {    void add(Object obj);}其后实现该接口

@Repository(value = "baseDaoImpl")public class MongoDBBaseDaoImpl implements BaseDao {

@Autowired    @Qualifier("mongoTemplate")    protected MongoTemplate mongoTemplate;

@Override    public void add(Object obj) {        this.mongoTemplate.insert(obj);    }}service层如下：

@Service(value = "userInfoService")public class UserInfoServiceImpl extends MongoDBBaseDaoImpl implements UserInfoService {}最后定义了Controller类如下：

@Controllerpublic class TestController {

@Resource    private UserInfoService userInfoService;

@RequestMapping(value = "test",method = RequestMethod.GET)    public String test(){        UserInfo userInfo = new UserInfo();        userInfo.setNickname("nick");        userInfo.setUsername("Nike2");        userInfo.setSex("female");        userInfo.setAge("27");        userInfoService.add(userInfo);        return "test";    }}到此为止，一个简单的SpringMVC整合MongoDB就完成，启动该项目，在浏览器中输入http://localhost:8080/test后，查询Mongo数据库，可以发现其中多了一条数据。
