作为IT届的小弟，本篇作为本人的第一篇手记，还希望各位大牛多多指点，以下均为个人学习所得，如有错误，敬请指正。本着服务IT小白的原则，该手记比较详细。由于最近使用postgre开发大型项目，发现了关系型数据库的弊端及查询效率之慢，苦心钻研之下，对nosql的mongoDB从无知到有了初步了解。 项目环境：win10+IntelliJ IDEA2016+maven3.3.9+MongoDB 3.2+JDK1.7+spring4.1.7 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 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：<localRepository>F:\.m2\repository</localRepository> <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> 这里不实用idea自带maven插件，改用3.3.9 图片描述 项目结构：图片描述 这里dao与mongoDao分别为mongoDB的两种查询方式： dao为JPA的查询方式（请参考springdataJPA） mongoDao使用mongoTemplate，类似于关系型数据库使用的jdbcTemplate 不罗嗦，上代码 先看配置文件 spring-context.xm为最基本的spring配置 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"

</project> 两个实体类： /** * Created by DuLida on 2016/10/20. */ 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; } @Override public String toString() { return "Address{" + "city='" + city + '\'' + ", street='" + street + '\'' + ", num=" + num + '}'; } } /** * Created by DuLida on 2016/10/20. */ @Document(collection="person") public class Person implements Serializable { @Id 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 getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } @Override public String toString() { return "Person{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + ", address=" + address + '}'; } } 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); 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 /** * Created by DuLida on 2016/10/21. */ public interface PersonMongoDao { List<Person> findAll(); void insertPerson(Person user); void removePerson(String userName); void updatePerson(); List<Person> findForRequery(String userName); } @Repository("personMongoImpl") public class PersonMongoImpl implements PersonMongoDao { @Resource private MongoTemplate mongoTemplate; @Override public List<Person> findAll() { return mongoTemplate.findAll(Person.class,"person"); } @Override public void insertPerson(Person person) { mongoTemplate.insert(person,"person"); } @Override public void removePerson(String userName) { mongoTemplate.remove(Query.query(Criteria.where("name").is(userName)),"person"); } @Override public void updatePerson() { mongoTemplate.updateMulti(Query.query(Criteria.where("age").gt(3).lte(5)), Update.update("age",3),"person"); } @Override 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： /** * Created by DuLida on 2016/10/20. */ @RunWith(SpringJUnit4ClassRunner.class) //告诉junit spring配置文件 @ContextConfiguration({"classpath:spring/spring-context.xml","classpath:spring/spring-mongo.xml"}) public class PersonDaoTest { @Resource private PersonDao personDao; /*先往数据库中插入10个person*/ @Test 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("石家庄","裕华路",i))); } personDao.save(persons); } @Test public void findMongo() { System.out.println(personDao.findByAge(2,8,"name6")); } } mongoTemplate查询的测试类 /** * Created by DuLida on 2016/10/21. */ @RunWith(SpringJUnit4ClassRunner.class) //告诉junit spring配置文件 @ContextConfiguration({"classpath:spring/spring-context.xml","classpath:spring/spring-mongo.xml"}) public class MongoTemplateTest { @Resource private PersonMongoImpl personMongo; @Test public void testMongoTemplate() { //personMongo.insertPerson(new Person("wukong",24,new Address("石家庄","鑫达路",20))); //personMongo.removePerson("name3"); //personMongo.updatePerson(); //System.out.println(personMongo.findAll()); System.out.println(personMongo.findForRequery("wukong")); } } 注意测试前请先通过testMongo()向数据库中插入数据。 项目源码Git地址，仅供学习使用：https://github.com/dreamSmile/mongo.git
