idea 搭建 springdata+mongodb+maven+springmvc
今天我们来学习一下 SpringData 操作 MongoDB。
项目环境：IntelliJ IDEA2017+maven3.5.0+MongoDB 3.2+JDK1.7+spring4.3.8
推荐网站（适合学习各种知识的基础）：http://www.runoob.com/
mongo 安装请参考：http://www.runoob.com/mongodb/mongodb-window-install.html
1. 创建 maven 工程
首相创建 maven 工程，New project:
这里不使用 idea 自带 maven 插件，改用下载好的 3.5.0 版 maven；
由于最近 osChina 的 maven 仓库挂掉，推荐大家使用阿里的镜像，速度快的飞起maven配置：D:\apache-maven-3.5.0\conf\setting.xml中找到mirrors:
<mirrors>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
项目结构如下图，手动创建相关文件夹及文件，并设置文件夹的对应属性：
至此，maven 工程创建完毕。
2. 访问 mongodb 数据方式
这里dao与mongoDao分别为mongoDB的两种查询方式：
(1)
dao为JPA的查询方式（请参考springdataJPA）；(2)
mongoDao使用mongoTemplate，类似于关系型数据库使用的jdbcTemplate。
3. 详细代码
先看配置文件
spring-context.xml 为最基本的spring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:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 开启注解 -->
<context:annotation-config/>
<!-- 扫描 service 包嗲所有使用注解的类型 -->
<context:component-scan base-package="com.lewis.mongo">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<span class="hljs-comment"><!-- 导入mongodb的配置文件 --></span>
<span class="hljs-tag"><<span class="hljs-name">import</span> <span class="hljs-attr">resource</span>=<span class="hljs-string">"spring-mongo.xml"</span>/></span>
</beans>
spring-web.xml 为springmvc的基本配置:
<?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:mvc="http://www.springframework.org/schema/mvc"

http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 配置 springmvc-->
<!--1. 开启 springmvc 注解模式 -->
<context:annotation-config/>
<!-- 简化配置：
(1) 主动注册 DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter
(2) 提供一系列功能：数据绑定，数字和日期的 format @NumberFormt @DataTimeFormat，xml json 默认的读写支持 -->
<mvc:annotation-driven/>
<!--servlet-mapping-->
<!--2 静态资源默认的 servlet 配置，
（1）允许对静态资源的处理：js，gif
（2）允许使用“/”做整体映射 -->
<!-- 容器默认的 DefaultServletHandler 处理 所有静态内容与无 RequestMapping 处理的 URL-->
<mvc:default-servlet-handler/>
<!--3: 配置 jsp 显示 viewResolver-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
<span class="hljs-comment"><!-- 4自动扫描且只扫描@Controller --></span>

</beans>
spring-mongo.xml 为 mongo 配置:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

pom.xml，这里要注意的是junit版本需要 4.12 以上，不然 idea 会报错；spring-data-mongodb版本要 1.10.1 以上；

两个实体类：
Address.java:
package com.lewis.mongo.entity;
/**
Created by liu on 2017/6/7.
*/
public class Address {private String city;
private String street;
private int num;public Address() {
}public Address(String city, String street, int num) {
this.city = city;
this.street = street;
this.num = num;
}public String getCity() {
return city;
}public void setCity(String city) {
this.city = city;
}public String getStreet() {
return street;
}public void setStreet(String street) {
this.street = street;
}public int getNum() {
return num;
}public void setNum(int num) {
this.num = num;
}
public String toString() {
return "Address{" +
"city='" + city + ''' +
", street='" + street + ''' +
", num=" + num + '}';
}
}
Person.java:
package com.lewis.mongo.entity;
import java.io.Serializable;
import org.bson.types.ObjectId;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
/**
Created by liu on 2017/6/7.
*/
public class Person implements Serializable {
private ObjectId id;
private String name;
private int age;
private Address address;public Person() {
}public Person(String name, int age, Address address) {
this.name = name;
this.age = age;
this.address = address;
}public ObjectId getId() {
return id;
}public void setId(ObjectId id) {
this.id = id;

public String toString() {

}
}
JPA 的 dao，注意这里只要继承 MongoRepository 不用写注解 spring 就能认识这是个 Repository，MongoRepository 提供了基本的增删改查，不用实现便可直接调用，例如 testMongo 的 personDao.save(persons);
PersonDao.java:
package com.lewis.mongo.dao;
import com.lewis.mongo.entity.Person;
import org.bson.types.ObjectId;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.mongodb.repository.Query;
import java.util.List;
/**
-
Created by liu on 2017/6/7.
*/
public interface PersonDao extends MongoRepository<Person, ObjectId> {
@Query(value = "{'age': {'$gte': ?0,'$lte': ?1},'name': ?2}", fields = "{'name': 1,'age': 1}")
List<Person> findByAge(int age1, int age2, String name);
}
mongoTemplate 的 dao，PersonMongoDao.java:
package com.lewis.mongo.mongoDao;
import com.lewis.mongo.entity.Person;
import java.util.List;
/**
Created by liu on 2017/6/7.
*/
public interface PersonMongoDao {
List<Person> findAll();
void insertPerson(Person user);
void removePerson(String userName);
void updatePerson();
List<Person> findForRequery(String userName);
}
PersonMongoImpl.java:
package com.lewis.mongo.mongoDao;
import com.lewis.mongo.entity.Person;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.stereotype.Repository;
import javax.annotation.Resource;
import java.util.List;
/**
Created by liu on 2017/6/7.
*/
public class PersonMongoImpl implements PersonMongoDao {
private MongoTemplate mongoTemplate;
public List<Person> findAll() {
return mongoTemplate.findAll(Person.class, "person");
}
public void insertPerson(Person person) {
mongoTemplate.insert(person, "person");
}
public void removePerson(String userName) {
mongoTemplate.remove(Query.query(Criteria.where("name").is(userName)), "person");
}
public void updatePerson() {
mongoTemplate.updateMulti(Query.query(Criteria.where("age").gt(3).lte(5)), Update.update("age", 3), "person");
}
public List<Person> findForRequery(String userName) {
return mongoTemplate.find(Query.query(Criteria.where("name").is(userName)), Person.class);
}
}
JPA 查询的测试类，PersonDaoTest.java:
import com.lewis.mongo.dao.PersonDao;
import com.lewis.mongo.entity.Address;
import com.lewis.mongo.entity.Person;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
import java.util.ArrayList;
import java.util.List;
/**
Created by liu on 2017/6/7.
*/
// 告诉 junit spring 配置文件
public class PersonDaoTest {
private PersonDao personDao;/先往数据库中插入 10 个 person/
public void testMongo() {
List<Person> persons = new ArrayList<Person>();
for (int i = 0; i < 10; i++) {
persons.add(new Person("name" + i, i, new Address("广州市", "天河区", i)));
}
personDao.save(persons);
}
public void findMongo() {
System.out.println(personDao.findByAge(2, 8, "name6"));
}
}
mongoTemplate 查询的测试类，MongoTemplateTest.java:
import com.lewis.mongo.entity.Address;
import com.lewis.mongo.entity.Person;
import com.lewis.mongo.mongoDao.PersonMongoImpl;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
/**
Created by liu on 2017/6/7.
*/
// 告诉 junit spring 配置文件
public class MongoTemplateTest {
private PersonMongoImpl personMongo;
public void testMongoTemplate() {<span class="hljs-comment">//personMongo.insertPerson(new Person("Lewis",24,new Address("广州","天河",20)));</span> personMongo.removePerson(<span class="hljs-string">"name3"</span>); personMongo.updatePerson(); System.out.println(personMongo.findAll()); System.out.println(personMongo.findForRequery(<span class="hljs-string">"Lewis"</span>));}
}
注意测试前请先通过
PersonDaoTest.java中的testMongo()方法向数据库中插入数据。
