Spring Data MongoDB 环境搭建详解大数据

一、开发环境

• spring版本：4.0.6.RELEASE

• spring-data-mongodb版本：1.4.1.RELEASE

• junit版本 4.11

• maven版本:3.0.5

二、pom.xml

使用Maven管理jar包

三、db.xml

spring mongodb 核心配置

<?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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 
    xmlns:mongo="http://www.springframework.org/schema/data/mongo" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tool="http://www.springframework.org/schema/tool" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
                        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
                        http://www.springframework.org/schema/context 
                        http://www.springframework.org/schema/context/spring-context-4.0.xsd 
                        http://www.springframework.org/schema/tx

                        http://www.springframework.org/schema/tool                       
                        http://www.springframework.org/schema/tool/spring-tool-4.0.xsd 
                        http://www.springframework.org/schema/mvc                  
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 
                        http://www.springframework.org/schema/data/mongo 
                        http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd"> 
 
    <!-- 
        <context:property-placeholder 
        location="classpath:sysconfig/properties/mongodb.properties" /> 
    --> 
 
    <!-- 定义mongo对象，对应的是mongodb官方jar包中的Mongo，replica-set设置集群副本的ip地址和端口 --> 
    <mongo:mongo id="mongo" host="127.0.0.1" port="27017"> 
        <!-- 一些连接属性的设置 --> 
        <mongo:options connections-per-host="8" 
            threads-allowed-to-block-for-connection-multiplier="4" 
            connect-timeout="1000" max-wait-time="1500" auto-connect-retry="true" 
            socket-keep-alive="true" socket-timeout="1500" slave-ok="true" 
            write-number="1" write-timeout="0" write-fsync="true" /> 
    </mongo:mongo> 
 
    <!-- mongo的工厂,通过它来取得mongo实例,dbname为mongodb的数据库名,没有的话会自动创建 --> 
    <mongo:db-factory id="mongoDbFactory" dbname="mydb" 
        mongo-ref="mongo" /> 
 
    <!-- 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.ithome.bean" 
        id="mongoConverter" /> 
 
    <!-- mongodb的主要操作对象,所有对mongodb的增删改查的操作都是通过它完成 --> 
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> 
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /> 
        <constructor-arg name="mongoConverter" ref="mongoConverter" /> 
    </bean> 
 
    <!-- mongodb bean的仓库目录,会自动扫描扩展了MongoRepository接口的接口进行注入 --> 
    <mongo:repositories base-package="com.ithome.bean" /> 
 
    <bean id="personDao" class="com.ithome.dao.impl.PersonDaoImpl"> 
        <property name="mongoTemplate" ref="mongoTemplate" /> 
    </bean> 
 
</beans>

四、实体 Bean

import java.io.Serializable; 
 
public class Person implements Serializable { 
 
    private static final long serialVersionUID = 1L; 
 
    private String id; 
    private String name; // 姓名 
    private String sex; // 性别 
    private String idCard; // 身份证号码 
    private String note; // 备注 
 
    /** 
     * 省略 set() get() 
     */ 
 
}

五、接口 PersonDao

import java.util.List; 
import com.ithome.bean.Person; 
 
public interface PersonDao { 
 
    /** 
     * 插入数据 
     * @param u 
     */ 
    public void insert(Person u); 
 
    /** 
     * 查询全部 
     * @return 
     */ 
    public List<Person> queryAll(); 
 
}

六、接口实现 PersonDaoImpl

import java.util.List; 
import org.springframework.data.mongodb.core.MongoOperations; 
import org.springframework.stereotype.Repository; 
import com.ithome.bean.Person; 
import com.ithome.dao.PersonDao; 
 
@Repository 
public class PersonDaoImpl implements PersonDao { 
 
    private MongoOperations mongoTemplate; 
 
    public void setMongoTemplate(MongoOperations mongoTemplate) { 
        this.mongoTemplate = mongoTemplate; 
    } 
 
    @Override 
    public void insert(Person u) { 
        mongoTemplate.insert(u); 
    } 
 
    @Override 
    public List<Person> queryAll() { 
        List<Person> user = mongoTemplate.findAll(Person.class); 
        return user; 
    } 
}

七、测试类

import java.util.List; 
import org.junit.BeforeClass; 
import org.junit.Test; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
import com.ithome.bean.Person; 
import com.ithome.dao.PersonDao; 
 
@org.junit.runner.RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "classpath:db.xml" }) 
public class PersonTest { 
 
    @BeforeClass 
    public static void setUpBeforeClass() throws Exception { 
    } 
 
    @Autowired 
    public PersonDao personDao; 
 
    @Test 
    public void insert() { 
        Person person = new Person(); 
        person.setName("zhangsan"); 
        person.setSex("男"); 
        person.setIdCard("110112100589911"); 
        person.setNote("无"); 
        personDao.insert(person); 
    } 
 
    @Test 
    public void getAll() { 
        List<Person> list = personDao.queryAll(); 
        for (Person p : list) { 
            System.out.println("ID: " + p.getId() + "  姓名：" + p.getName()); 
        } 
    } 
 
}
