SpringMVC整合MongoDB

?首先，在pom文件中新增spring-data-mongodb的依賴：

<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中導入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.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsdhttp://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" />    <!-- 導入mongodb的配置文件 --><import resource="spring-mongo.xml"/></beans>

在model層，新建UserInfo類

@Document
public 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層，先新建BaseDao接口

public interface BaseDao {
    void add(Object obj);
}
其后實現該接口

@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層如下：

@Service(value = "userInfoService")
public class UserInfoServiceImpl extends MongoDBBaseDaoImpl implements UserInfoService {
}
最后定義了Controller類如下：

@Controller
public 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";
    }
}
到此為止，一個簡單的SpringMVC整合MongoDB就完成，啟動該項目，在瀏覽器中輸入http://localhost:8080/test后，查詢Mongo數據庫，可以發現其中多了一條數據。
