Spring Data MongoDB 环境搭建

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

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <name>mongos</name>
    <url>http://maven.apache.org</url>

    <properties>
        <org.springframework-version>4.0.6.RELEASE</org.springframework-version>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

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/aop
                        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
                        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());
        }
    }

}
